过滤阴极真空电弧镀膜技术所制得氧化铝薄膜的结构和特性摘要:通过过滤阴极真空电弧镀膜技术制备氧化铝薄膜时,其内部结构、组成、形态、光学和机械性能被详尽的描述,这些都与制备时氧气的流量有关。

薄膜结构、组成、形态和性能都是很重要的,随着氧气流量的增加,薄膜的结构也由非晶体经过一系列变化到单晶体,随着O/Zr原子比率的增加和Z离子由低氧化作用的状态转化为Zr4+再一次形成非晶体。

形成这样的结构是由于其内部结构的变化而引起的,并且影响其形态和机械性能,以致这种非晶体薄膜表面有一些小簇,其光滑程度就像低硬度的多晶体薄膜。

当反射指数和系数相对接近最大值时,在发射率和光学带宽随着O/Zr比增加时,薄膜的组成来决其光学性能而非其密度。

1.说明在大气压力下由于三种不同温度有多种不同靶形态结构,单晶体时低于1170O C,四面体时为1170-2370O C,2370O C为立方体,知道2680O C时形成金属。

Zr有很高的反射指数,大光学带宽间距,和很低的光损失及在0.3-8范围内高透明度,所以被广泛的应用于光学领域。

此外,Zr具有很高的电介质,低泄露量等特点,最有可能代替做电解质的晶体管。

进而,由于Zr很低的传热性,它成为了装置中隔热层的首选。

Z其他的特性如:高硬度、高抗氧性也使其成为机械材料中的热门。

至今为止,已经有很多制备Z的方法,例如反应磁控溅射,离子辅助反应溅射,化学气相沉积等。

薄膜特性的优劣取决于制备过程及其参数。

过滤阴极真空电子弧镀膜技术,在低电压和高电流状态下工作。

通过磁性机械过滤器来防止微粒从阴极发射。

它提供了一种具有很高能量的沉积离子源,远大于相应的热蒸发和磁控溅射。

能有效去处宏观无用微粒,很明显能提高薄膜质量并拓展其应用。

固有的高能量提高薄膜的附着性和密度。

由于能力是离子辅助沉积中最重要的参数,这种制备的方法已经有了一些应用,已经应用于在高热平衡和高SP3状态下碳薄膜的制备,还合成了一些金属氧化物的薄膜。

然而对我们最有利的是,很少有关过滤阴极真空电子弧镀膜技术制备ZrO2薄膜的知识。

我们现在的工作是系统研究在不同O2流量与ZrO2薄膜的结构、组成、表面形态和性质之间的关系。

我们的结论表明薄膜的结构、组成特性都与O2流量有关系。

过滤阴极真空电子弧镀膜技术所制的薄膜特性与其他方法相比,更说明了该方法的优越性。

2.实验图1为制备设备。

该图已经详细反应了这个系统,各个部分都表现了出来。

该系统有一个双倍滤光器,可以使弧自身发射出微粒。

阴极Zr原子在120A电流下,阴、阳极瞬间接触点燃喷出的浆体,该浆体是从一个400mT的磁场放射出来并压缩的。

一个旋转泵和一个冷凝泵可使这个系统的压力达到4×10-6T。

O2通过一个有很多小孔的铜管进入Zr靶附近区域。

这种发射O2的方式可使O2电离到最大程度,因此增加了与浆体的接触使得Zr与O2之间发生充分的反应。

O2流量可选择10-98sccm,在制备过程中,随着O2流量的增加,靶的氧化更加充分。

O2增加使得靶材充分氧化,并且损失了冷凝粒子,使得制备的速率 75nm/s降至35nm/s。

`在室温下薄膜生长在n-si和石英表面。

基片被放在制备室之中,按顺序被丙酮、酒精和未电离的水清洗。

所制得的薄膜厚度大约在200 nm。

通过由CUKα做源的XRD法可得出薄膜所处阶段和晶体结构。

光谱计记录下反射率等参数,光学特性也被软件检测。

主要特征和组成分析被XPS通过ALK辐射测得到。

不可使用没有清洗过的样品溅射,以免所溅射得到的薄膜化学组成发生变化。

图13.结果3.1结构图2表明在不同O2流量ZrO2薄膜由XRD测得的结构,在10sccm时,在曲线中对应着边缘处,而系统峰值在32.4o C附近,为标准的结构。

这个高峰来自于没有完全氧化的ZrO固体。

由于类似现象可看出峰值点又是不对称的和急剧变化处。

当O2流量增加至20sccm,一个最高峰是当晶体阶段,相对弱的高峰是多晶体阶段。

氧气流量决定峰值。

我们可以检测出它是怎么影响薄膜结构的。

在35sccm时,出现了更多的弱高峰,在 m(200)处峰值变得很弱,在m(-202m)变得很强。

然而当氧气的流量增加至65sccm时,薄膜由多晶体变为无定形,在弯曲处出现更宽的高峰。

结构的不同反应出02流量在薄膜结构形成中扮演了很重要的角色。

正在一定流量范围内(20-50sccm)薄膜保持在多晶体状态,而在纯单晶体阶段在不同的范围内。

3.2化学组成和化学状态通过典型的XPS光谱测量可以得到由光电离子及Zr和O转变达到高峰,在与空气接触后的抽样中经过观察C1S是主要表面组成部分。

在Zr3d和O1S处出现两个高峰。

图4中可看到常态的元素和由XPS测得的局部光谱。

频谱非常接近标准单晶体的 ZrO2。

两个高峰,Zr3d5/2和Zr3d3/2时的能量分别为181.8ev和184.2ev,非常接近在中标准ZrO2,并且是对称的,在氧化状态的薄膜中只有它。

他们的强度比率和导致旋转轨道在1.5ev和 2.4ev的能量间隔和其他研究是一致的。

一个不对称的高峰能分解为的529.6evLBE能量和531ev的HBE,与报告中的那些类似。

相比之下,薄膜沉积速率很低时,例如35sccm,Zr3d光谱是以某种方式不同的而O1S 频率是十分类似的。

出现较低能量接近其边缘,有形式为Zr,Zr n+,(n=1,2,3)氧化物存在。

可得出随着O流量的不同可转变为使得和发生充分的反应。

氧化程度的不同也被2表明,薄膜中O和Zr的原子比率可由它们在峰值区域的灵敏度算出。

O1S的HBE是一个小片段所以高峰不能被确定。

正如预料,O/Zr比增加可导致更多氧化。

可看到在薄膜沉积速率为时,O/Zr比为1.98:1接近原子比为2:1,在65sccm及起以上,薄膜3.3表面形态五表现了在65sccm时典型的薄膜。

在薄膜表面,小簇由相同的冷凝的原子成。

这表面相当干净和光滑,RMS粗燥率小于0.1nm在1um×1um区域内。

上面提到的高能量轰击微粒使得形成干净、光滑的表面,这些微粒运动时损失粒子,或者促进原子和提供足够能量运动到生长表面相结合,再一次建议流量的边界值不影响原子的运动,与XRD测量结果一致。

流动速率XRD分析出的薄膜结构的改变有关。

有趣的是,薄膜的形态似乎也被O2在10sccm时,薄膜表面的簇会很大。

这种簇的变化可以反映出薄膜表面粗糙。

XRD分的流量有关。

换句话说,与无定型薄膜析出的薄膜结构的改变说明薄膜表面结构与O2相比较,这种多晶体薄膜在20-50sccm速率下在表面形成巨大的簇并且看起来很粗糙。

3.4机械性能薄膜的硬度是测量抵制塑性变形和确定载荷符合凹行区域的峰值。

实际上,硬度通过卸载数据所构成能量方程来表现。

薄膜的机械性能作为流量方程显示在图9,其值平均至少出现了3次,微硬度和是依赖于氧气流量。

当流量由10sccm增加到20sccm,硬度几乎维持为13.6GP,再增加流量会导致硬度急速提高。

在35。

50,硬度仍然在增加,超出50sccm后,薄膜开始变软,并且在65sccm会降至13.4GPA。

显然,硬度的改变非常接近在XRD式样中观察的。

这表明硬度是由薄膜的结构确定而非特性确定其硬度,这与KAO的报告结果不一致。

4.结论通过过滤阴极真空电弧镀膜技术制备薄膜,研究了在不同氧气流量时,薄膜的结构、组成、形态、光学性能和机械性能,最终的流量达到了98sccm。

经研究发现O2流量的增加,薄膜的结构由无的流量是薄膜结构、组成、特性的重要参数。

随着O2定型到不同氧化率的单晶体再到无定型;随着0/Zr原子比的增加,Zr原子由低氧化率到Zr。

这种与氧气流量有关的结构趋势会导致薄膜组成的改变并且决定表面形态和薄膜的机械性能。

g.q. yub.k. tay_z.w. zhaoStructure and propertiesof zirconium oxide thin filmsprepared by filtered cathodic vacuum arcSchool of Electrical and Electronic Engineering, Nanyang TechnologicalUniversity,Singapore, 639798, SingapoReceived: 19 September 2003/Accepted: 17 January 2004Published online: 1 April 2004 • © Springer-Verlag 2004ABSTRACT Zirconium oxide (ZrO2) thin films deposited atroom temperature by the filtered cathodic vacuum arc (FCVA) technique are detailed in terms of the film structure, composition, morphology, and optical and mechanical properties, which are tailored by the oxygen (O2) flow rate during deposition. The relationships between the film structure, composition, morphology, and properties are emphasized. With an increasing flow rate, the film evolves in structure from amorphous, through a pure monoclinic phase with varying preferential orientation, to amorphous again, accompanied by an increase in the O/Zr atomic ratio and a conversion of Zr ions from low oxidation states into Zr4+. Such a structural trend arises from the change in composition, and influences the film morphology and mechanical properties so that the amorphous films exhibit small clusters on the surface and smoother morphology as well as lower hardness compared with the polycrystalline films. Thefilm composition rather than the density dominates the optical properties, where the transmittance and the optical band gap increase with increasing O/Zr values, while the refractive index and extinction coefficients behave conversely with the lowest refractive index (2.16 at 550 nm) approaching the bulk value (2.2).PACS 68.55.Jk; 78.66.Nk; 68.37.Ps1. IntroductionZirconium oxide (ZrO2) has three temperature dependent polymorphic structures at atmospheric pressure. A monoclinic phase is stable at temperature below 1170 ◦C, a tetragonal between 1170 and 2370 ◦C, and a cubic from 2370 ◦C to the melting point at 2680 ◦C. ZrO2 is widely used in optical fields [1–3], because of its high refractive index,large optical band gap, and low optical loss and high transparency in the 0.3–8 μm range. In addition, ZrO2 is a promising candidate to replace silicon dioxide as the gate dielectric in transistors, due to its high dielectric constant (∼25), lowleakage current level, etc. [4–6]. Furthermore, ZrO2 has potentialas a thermal barrier coating in devices due to its low thermal conductivity [7, 8]. Other properties such as high hardness, large resistance against oxidation, also make it interesting as a mechanical material [9]. To date, many efforts to prepare ZrO2 have been made by various deposition techniques, for example, reactive magnetron sputtering [10–13], ion-assisted reactive sputtering or evaporation deposition [8, 14–25], solgelmethods [26], chemical vapor deposition [4,17], and so on. The film properties are generally strongly dependent on the deposition process and parameters.The filtered cathodic vacuum arc technique (FCVA) [27–29], operated at low pressure, low voltage, and high current, effectively eliminates micro-sized (0.1–10 μm) macroparticles from being emitting from cathode materials during arcing by means of mechanical, magnetic, or electrical filters,or a combination of these. It also provides an intense source of fully ionized deposition specieswith energies (50∼150 eV) greater than counterparts produced in thermal evaporation or magnetron sputtering [30, 31]. The removal of detrimental macro-particles undoubtedly improves the resulting film quality and extends the application of the deposition technique. The inherent high-energy could increase the film adhesion and the packing density. The full ionization of the deposition species allows tailoring of the film properties with substrate bias, since kinetic energy is one of the most important parameters as in ion beam assisted deposition (IBAD) [8]. This technique has been demonstrated in the preparation of a diamond-like carbon film with high thermal stability and a high sp3 [32], to fill trenches [33, 34], as well as the synthesisof certain metal oxide films [35, 36]. However, to the best of our knowledge, little work has been reported on ZrO2synthesis by the (FCVA) technique.In the present work, we systematically investigate the structural, chemical composition, optical, and mechanicalproperties of ZrO2 films deposited at different oxygen (O2) flow rates by FCVA. The emphasis is placed on the relationships between structure, composition, surface morphology, and properties of the films. Our results disclose that the structural and compositional properties of the films are considerably influenced by the O2 flow rate. The variation in compositioninduces structural transformation from amorphous through a pure monoclinic phase to amorphous again, and determines the optical properties,whereas the change in structure controls the mechanical properties and affects the surface morphology. The properties of the films are also crosscomparedwith those of films prepared by other methods to highlight the FCVA features.2 ExperimentalA schematic diagram of the FCVA deposition system is shown in Fig. 1. The details regarding the main principles of the system have been described elsewhere [37]. Briefly, the system incorporates an off-plane double bendfilter, which effectively removesmacro-particles originating from the arc itself. A Zr cathode (99.98% pure) operated at 120 A dc current is ignited through instant contact between cathode and anode to obtain the plasma, which is steered out by a toroidal magnetic field fixed at 40 mT to condense on a substrate. The base pressure of the system, evacuated by a rotary pump and a cryo-pump, can reach 4×10−6 Torr. O2 gas (99.99% pure) is led into the region near the Zr target through a copper tube on which many tiny holes are distributed.This way of introducing O2 is expected to maximize O2 ionization due to its relatively increased collision with the plasma, possibly promoting a chemical reaction between O2 and Zr. The O2 flow rate chosen here is varied from 10 to 98 sccm corresponding to 1×10−4 to 4.6×10−4 Torr. During deposition, the deposition rate decreases from 75 to 35 nm/min with an increasing O2 flow rate as a result of increased .oxidization of the target, and collision-induced loss of condensing particles. The films are grown on n-Si (100) and quartz substrates at roomtemperature. All the substratesare sequentially cleaned in acetone, alcohol, and de-ionizedwater prior to being loaded into the deposition chamber. All the films being investigated are generally around 200 nm thick. The film phase and crystal structure are identified by Xray diffraction (XRD) with a Cu Kαsource at 1.54 Å. Transmittance and reflectance are recorded from 200 to 1100 nm with a spectrometer. Optical constants are obtained by fitting optical spectra with Scout software [38]. Core level spectra and compositional analysis areand compositional analysis are carried out by X-ray photoelectronspectroscopy (XPS) with monochromatic Al Kαradiation (1486.6 eV). No sputter cleaning of the samples is performed to avoid changes in chemical compositions induced by preferential sputtering. The spectrum obtained iscorrected by an adventitious C1s peak at 284.6 eV. Surface morphology is measured by atomic force microscopy (AFM) in tapping mode (Dimension 3000 scanning probe microscope from Digital Instruments). The mechanical properties on a nano-scale are obtained by a nanoindentation techniqueapparatus (Hysitron Inc.) attached to the above AFM equipment.Nanoindentations were made using a Berkovich diamond indenter and the maximum loads applied were 500 μN. The indenter was loaded at 100 μN/s, held at peak load for 5 s and then finally unloaded at 100 μN/s.3 Results3.1 StructureFigure 2 shows theXRDpatterns for ZrO2 films deposited at differentO2 flowrates.At 10 sccm, a broad but symmetric peak centered at around 32.4◦is observed in curve (a), indicative of an amorphous structure. The peak is believed to come from an oxygen-deficient Zr-O solidsolution [40].Wong et al. [13] also reported a similar phenomenon, where, however, the peak was unsymmetric and sharp. As the O2 flow rate increases to 20 sccm (Fig. 2b) ), one peak at 33.7◦assigned to (200) planes of monoclinic phase (denoted as m(200)) is predominant, accompanied by the appearance of other weak peaks also from the monoclinic phase. This rapid occurring of diffraction peaks shows that so much oxygen is incorporated that sufficient ZrO2 crystallite forms which can be detected. The easy combination between Zr and O is possiblyrelated to charged and therefore active emitted species, as well as further stimulated by energetic Zr particles bombarding the surface as in IBAD. At35 sccm, in addition to more weak peaks, them(200) peak becomes weaker while the m(-202) peak gets stronger. When the O2 flow rate goes up to 50 sccm, the dominant peak is changed tom(-111) while many more monoclinic peaks are produced.3.2 Chemical compositions and chemical statesIt was concluded from a typical XPS survey spectrum (not shown) that besides the peaks contributed by photoelectrons and Auger transitions of Zr and O, C1s is observed as well, which is mainly from surface contamination after exposure of the sample to air. The two strong peaks at 185.9 and 533.2 eV are identified as Zr 3d and O1s, respectively. Fig. 4 presents the normalized Zr 3d (a) and O1s (b) XPS local spectra for the film prepared at 50 sccm. The spectra closely resemble those observed in standard monoclinic ZrO2 [42]. Two peaks, Zr 3d5/2 and Zr 3d3/2 observed at binding energies of 181.8 and 184.2 eV, very near to the values of Zr4+ in ZrO2 [42], are symmetrical, denoting that only one oxidation state of Zr exists in the film. Their intensity ratio (I3d5/2/I3d3/2) and energy interval (∆3d5/2–3d3/2) resulting from spin-orbit splitting are 1.5 and 2.4 eV, in agreementwith other studies [20, 42]. An asymmetric O1s peak can be decomposed into two components peaked at a low binding energy (LBE) of 529.6 eV and high binding energy (HBE) of 531.6 eV, quite comparable with reported ones [14, 43]. It has been accepted that the LBE peak is assigned to the oxygenin zirconia [14, 20, 43] while the HBE is attributed to oxygen present in the hydroxide and/or adsorbed oxygen or carbonates or higher-valent oxides [14, 42, 44, 45].Matsuoka et al. [20]ascribed it to oxygen possibly bound to Zr. In contrast, for the film deposited at the low flow rate, i.e., 35 sccm, the Zr 3d spectrum is somehow different whereas the O1s spectrum is very similar.A shoulder of the Zr 3d5/2 clearly appears at the lower binding energy side (Fig. 4c), indicating that other oxidation states of Zr (Zrn+, n = 1, 2, 3) occur. This shoulder is attributed to Zr suboxides [14, 20]. It can be concluded from this discrepancy that with increasingflow rate, Zrn+ (n ≤3) will convert into Zr4+ due to a full reactionbetween Oand Zr in the films. This consistent variation in the oxidation state of Zr ions with the film composition was also reported in [20]. The atomic ratio of Oto Zr (O/Zr) in the films can be calculated with their respective peak areas cali- brated by their sensitivity factors (0.66, 2.1, 0.66 forO1s and Zr 3d). For the calculation, theO1s HBE peak is not includeddue to its small fraction. As expected, theO/Zr ratio increases with more addition of oxygen (not shown). Note that for the film deposited at 50 sccm, the O/Zr ratio obtained is approximately 1.98 : 1, near to the ideal stoichiometric ratio of 2 : 1. At 65 sccm and above, the films areover-stoichiometric (∼2.2 : 1).3.3 Surface morphologyFigure 5a presents a typical top-view AFM image of the film at 65 sccm. On the film surface, the clusters composed of many condensing adatoms are uniformly distributed. The surface is quite clear and smooth, with its rootmean-square (RMS) roughness less than 0.1 nmover the area of 1μm×1 μm. This clearness and smoothness is associated with the above-mentioned high energy of bombarding particles, which possibly removes loose particles (so-called “self-sputtering”) or promotes bonding between adatoms andoffers the adatoms enough lateral mobility on the growing surface [39, 46], again suggesting that the flow rate range selected does not greatly affect the adatoms mobility, in accordance with the XRD results. Interestingly, the film morphology seems to be affected by the O2 flow rate as well. At 10 sccm, the clusters distributed on the film surface are similar in size to that forthe film at 65 sccm. However, in the range of 20 to 50 sccm, larger clusters are present on the surface. This change in cluster size is also reflected in the curve of roughness versus the O2 flow rate (Fig. 5b) the O2 flowrate (Fig. 5b), where the roughness is larger for a 20–50 sccm flow rate range. The flowrate-dependent surface morphology could be correlated with the film structural change as drawn from XRD analysis. In other words,compared with the amorphous films, the polycrystalline films formed in a 20–50 sccm flowexhibit larger clusters on the surface and look relatively rougher.3.4Mechanical propertiesThe film hardness is a measure of resistance to plastic deformation and defined as the peak load divided by the corresponding indentation area. Practically, the hardness is obtained by fitting the unloading data with a power law equation [39]. The mechanical properties of the films as a function of flow rate are displ ayed in Fig. 9, where the v alues are averaged at least three times. Both the microhardness and Young’s modulus are apparently dependent upon the O2 flow rate. When flow rate increases from 10 to20 sccm, the hardness almost stays at about 13.6GPa. Further increasing the flow rate leads to an abrupt increase in hardness. At 35 and 50 sccm, the increase is pronounced. However, beyond 50 sccm, the film starts to become soft and at 65 sccm drops to 13.4GPa in hardness. Clearly, thechange in hardness is very similar to the structural variation observed in the XRD patterns. This signifies that the film structure rather than the composition determines the film hardness, which is not in agreement with the result reported by Kao [19].4 ConclusionsThe structure, composition, morphology, optical, and mechanical properties of ZrO2 films deposited by the filtered cathodic vacuum arc (FCVA) technique have been investigated at varyingO2 flowrates, up to 98 sccm. TheO2 flow rate is found to be an important parameter in controlling the film structure, composition, and properties. With increasing O2 flow rate, ZrO2 film evolves in structure from amorphous, through to a pure monoclinic phase with varying preferential orientation, to amorphous again, concurrent with an increase in the O/Zr atomic ratio, and a conversion of Zr ions from lowoxidation states into Zr4+. Such a trend in the structure with the O2 flow rate is a result of a change in the film composition, and determines the surface morphology and the mechanical properties of the film. The film composition instead of the film density, dominates the optical properties, where transmittance and optical band gap increase with increasing O/Zrvalue, whereas the refractive index and extinction coefficients behave inversely.。

Design theory of stored testing and measuring system and its realization in dynamic data measurement of missileBeijing Institute of TechnologyStored testing and measuring is a kind of dynamic test technology wherein micro data recording gauge is embedded in the object to be measured in the condition that there is no or allowable effect on it. The information is collected and memorized at the spot in real time. The recording device is recollected and computer is used to process the measured information. The key to realize dynamic stored testing and measuring lies in developing of stored testing and measuring system (STMS) that can work normally in the testing environment and have either no effect on the object to be measured or the effect is in the allowable range.The definition, character, application field and basic elements are studied systematically. The overall review of research and development situation in home and oversea is given. During Ph.D candidate studying period, the author has presided over the development of data-recording devices used on 60 channels dynamic data testing and measuring (TM) during atmosphere-reentering of intercontinental ballistic missile (ICBM) warhead, intelligent missile blockbox used on dynamic data-recording of certain heavy anti-tank missile flight, anti-warship missile slip track flight fuse data testing and measuring system, cannon shoot missile ball cartridge flight data-recording device, STMS of inner overloading curve of penetrative pill and ball chamber. Based on these experiences the author analyses thoroughly the inner rules of testing and measuring technology and summarize the design concept and design rules in a philosophical view. The design principles that can conduct theengineering practice of STM are established, which make the design of STMS optimized in a logical and rational way.The STMS researched in the paper mainly used in the special environment with the following attributes: (1) transient single process;(2)multi-parameter interrelation, strict time-relation and the need of precise measuring simultaneously; (3) analogue and digital information, high range transient signal and micro range slow-change signal exist simultaneously (the range difference greater than four orders and both the amplitude-testing and the process-recording is needed); (4) bad testing and measuring environment, for example, high temperature up to 3000℃, high press up to 1000Mpa, 100,000g strong impact vibration , high rotate speed and strong magnetic disturbance; (5)the measured system is high-technology product with expensive test (up to tens of millions RMB for one experiment); (6) small test space (no disturbance to the tested system is required and effect be smallest); (7) difficult to recovery; and so on.After systematically studying many of the STMS examples, the design theory and ten microscopical design principles of STMS are presented. They include realizability of working principle, recollectability of testing and measuring data, matching and/or harmonizing, compatibility, environment-adaptability, reusing and calibrationability, flexible design, modularization design, optimizing and trade-off of technology schemes. The conception of state design of STMS is firstly presented. The basic conceptions (for example, STMS state, state variable, state space, state net, state assemble and state chain) are defined, followed by studying of state assemble, establishing of state chain and/or state net design principles and methods. Further, their application scope and typical applications are illustrated. The time power factor theory andthe mathematics description of system state and its transformation are presented.Considering STMS as an information transmission system, the information transmission model of it is established. The testing and measuring information flow, equivalent information transmission model and noise model are analyzed. From the information transmission view, the similarity between STMS and Shannon communication system is compared to establish the theory basis for studying TM channel by application information theory.Quantify algorithmic defining information of measured signal that make use of entropy and entropy power has been presented, including TM channel capacity principle, the maxim interinformation principle and information rate distortion principle. Channel capacity of continuous analogue signal TM and anti-disturbance capacity limitation. The relation equation between STM channel transmission information and signal energy as well as TM channel anti-disturbance capacity limitation equation is established. The optimization analogue signal TM channel is presented, based on analysis of channel frequency character and information entropy, the maxim SNR condition of TM channel and the condition wherein both the minim TM channel output waveform and the maxim SNR condition are obtained. In the design of TM channel information the conception of distortion and rate distortion is introduced, moreover, the calculation equation of TM channel information rate distortion function is established.STMS digital signal TM channels are composed of one or more duality signal channel. In the paper, the digital test channels are synthesized as a combinaiton of “Z” channel and the channel of symmetric disturbed information. The basic channel and channel capacity as well as caculaiton of channel overlap probability are researched. Moreover, the informationchannels capacity and the best channels layout of test instruction channels and test data channels are discussed.Sampling and quantizing are the most important technology in STMS, which is related to information obtaining quality and STM precision. In common sampling TM system, the sampling frequency setup is inclined to be high (especially while the measured object is not known clearly) in order to obtain enough data. Thus, there is much information redundancy. Real time information compression technology must be developed so that more information that is useful can be recorded in the limited memory (reversely, the STMS cost can be reduced since the needed memory capacity is compressed).According to the attribute of the measured signal, the TM requirement, working environment and so on, the basic problems of STM sampling design are researched. Four STM sampling strategy (uniformity sampling, automatic subsection uniformity sampling, programmable self-adaptive subsection uniformity sampling and self-adaptive sampling) are presented. The algorithm of zero order and one order predictable self-adaptive sampling is introduced in detail. The source of sampling error and the method to avoid it are analyzed and researched.Two kinds of sampling signal quantizers (uniformity and ununiformity) are presented. The information rate distortion function of the uniformity quantizer and the SNR algorithm are established. The signal capacity and multi-channel information TM principle is researched. The alternative principle of ADC multi-channel transducer is presented.Information can be stored in magnetic memory dielectric (MMD) or semiconductor CMOS memory. The latter is commonly used in STMS due to complex control, large volume and low anti over-loading ability of MMD.Information memory subsystem in STMS is studied and designed. Moreover, information memory effective principles are presented, including: (1) Designing memory controller in term of sampling sequence and recording mode. (2) For address generator composed of serial counter, the propulsion of address is done by the rising edge of WR signal. (3) Reducing memory sub system transmission time as possible as one can or making the CMOS memory operation during transmission invalid.Based on study of the information compression principle, two information compressive storing algorithms are presented. One is the algorithm of finite span error limitation used in real time dynamic data collecting. The computer simulation shows that the algorithm is very effective in real-time data compression and storage (data compressive ratio up to 13.6 and memory space save up to 92%). The other is data model compressive algorithm based on dynamic data modeling. Error tolerence technology and redundancy design of STMS are also researched.The double-circle-recording principal and method for improving reliability in measuring transient signals is illustrated. The essential technologies of STMS, including three-micro technology (microvolume, micropower, micronoise), anti high over-loading technology and interface technology etc. are discussed in detail.DF-5A missile is a kind of middle/long distance strategy nuclear missile. It is a necessary task in missile system research to test and measure missile ball cartridge flight dynamic data. In the past, dynamic data of missile system are obtained by the wireless remote test system and magnetic tape recording device. Since plasma intermit section is “black area” of wireless system, missile dynamic data can’t be recorded by wireless remote test. Memory resending wireless remote test can be used to obtain “black area” data, however, only limited dynamic data beforethe missile head contact the ground can be obtained since missile head approach the ground quickly after leaving the “black area”. The other method is micro magnetic tape device on board, but the device operation is complex and the reliability is low.Under the instruction of principle mentioned above, dynamic STMS for a new strategy missile full ballistic trajectory is developed. Without the complex operation of traditional magnetic tape recording devices before blasting-off, the STMS can both inspect 60 channels dynamic data from distance far to 300m and complete inspection and store of missile head system data without dismounting the missile. The device can precisely do the testing and measuring task while the missile head reenter atmosphere plasma intermit section. It’s reliability is higher than magnetic recording devices and it is simpler than wireless remote test system. As substitution of onboard magnetic devices, the STMS is one of the most important measure means of missile head.In the paper the design theory, basic element, working principle, essential technology and reliability experiment of the missile data-recording device are illustrated in detail.The onboard flight test of missile data-recording device was carried out in July, 1995. During atmosphere-reentering of missile head in the experiment the wireless system was invalid, the magnetic-recording devices was broken down, only the STMS devices obtained 60 channel dynamic data during DF-5A reentering atmosphere and the result is highly-praised by the customer.存储测试系统的设计理论存储测试是指在对被测对象无影响或影响在允许范围的条件下, 在被测体内置入微型数据采集与存储测试仪, 现场实时完成信息的快速采集与记忆, 事后回收记录仪, 由计算机处理和再现测试信息的一种动态测试技术。

测控技术与仪器专业外文翻译--温室温度和湿度智能控制系统

外文出处:Proceedings of the 3rd WSEAS Int. Conf. on CIRCUITS, SYSTEMS, SIGNAL and TELECOMMUNICATIONS.2009,51(17):120-125中文译文温室温度和湿度智能控制系统摘要:文章是基于嵌入式数据库的温室温湿度智能控制系统。

该系统提出在温室温湿度智能控制系统中采用嵌入式数据库技术,来控制温室作物的生长过程,以解决温室作物在温度和湿度控制的环境中生长过程并不理想的问题,以及提高系统的控制和成本效益的问题。

本文着重阐述了控制系统的结构,硬件、软件的设计和系统控制策略。

该控制系统具有硬件结构简单,成本低,易于使用和维护,温度和湿度数据兼测,稳定性好等优点。

关键语:嵌入式数据库,温度和湿度控制,数据过滤,温室,微控制器1 简介带有嵌入式微控制器技术、智能控制系统是科技发展的方向。

数据库是决策智能控制系统的核心,是智能控制的基础,它需要存储的专业知识和例子很多,也需要不断更新和添加实时数据。

为了确保在温室环境下正常的农业生产和高效率,提高农产品质量和数量,降低劳动强度,节约能源,是温室环境中对温度和湿度控制的必要条件。

目前在温室环境下中、低档产品的控制仍存在一些技术问题:一般只对一套温度和湿度控制使用。

由于作物对温度和湿度的要求不一样,用户必须经常调整控制器的设置,这难以满足现代农业生产的要求。

开发一个,低价格,系统可靠的温室是温湿度智能控制系统必需的。

温室环境是非线性的,参数分布,时变,长延迟,多变量耦合和多个控制对象的控制系统。

在温室中培育不同作物需要不同的栖息地。

在温室的温湿度控制系统中建立温室环境的嵌入式数据库系统的目的在于:(1)专家的经验与用户的实际需要相结合,灵活和自动化生产适合对具体对象种植的监测战略;(二)未提供关于作物栽培系统的专家经验,用户可以通过控制系统的独立运作的使用方式建立监测数据库,并长期保存;(三)建立可能对用户系统进行优化和修改的监测数据。

测控专业英语翻译Unit1Measurement,ControlandInstrumentationInstrumentation is defined as the art and science of measurement and control. Instrumentation engineers are responsible for controlling a whole system like a power plant. 译为:仪器可定义为测量和控制的艺术和科学。

仪器工程师负责控制整个系统,比如一个电厂。

An instrument is a device that measures and/or regulates process variables such as flow, temperature, level, or pressure. Instruments include many varied contrivances that can be as simple as valves and transmitters, and as complex as analyzers.译为:仪器是一种用来测量和/或调节过程变量(如流量、温度、液位或压力)的装置。

仪器包括许多不同的设备,可以像阀和变送器那样简单,也可以像分析仪那样复杂。

Instruments often comprise control systems of varied processes such as refineries, factories, and vehicles. The control of processes is one of the main branches of applied instrumentation. Instrumentation can also refer to handheld devices that measure some desired variable. Diverse handheld instrumentation is common in laboratories, but can be found in the household as well. For example, a smoke detector is a common instrument found in most western homes.译为:仪器通常由如精炼厂、工厂和车辆这些不同流程的控制系统组成。
