深圳电商现首波关门潮60%公司注册3年内死亡-深圳电商,公司注册.doc
深圳电商现首波关门潮60%企业注册3年内死亡-深圳电商,企业注册深圳电商现首波关门潮60%企业注册3年内死亡| 8月中旬，深圳华强北一家以手机为主业的中型悄悄关门。
该网站负责人胡先生告诉记者，生意难做主要是上游厂商直接开展电子商务，让他们这些中间商无利可图。
“7月份以来，我身边就有三家做手机B2C业务的网站关门。
”而深圳电子商务行业协会数据显示，注册运营的3700子商务公司，去年倒闭的近500家，占注册数13.5%。
中国电子商务协会网络营销推广中心主任、深圳单仁资讯集团董事长单仁称，传统企业纷纷转型网络营销并产生鲶鱼效应，会将那些缺乏传统业务根基的电子商务网站挤出市场。
随着越来越多传统企业纷纷触网，B2C倒闭风潮将会来得更猛烈。
三成电子商务企业在注册当年亡来自深圳电子商务行业协会的数据显示，截至去年底，深圳市注册的电子商务公司就达3700家，而去年倒闭或转型的电子商务企业接近500家。
“今年以来，深圳关门的电子商务网站比去年有增不减。
”业内人士告诉南都记者。
深圳电子商务协会秘书长高圣涵透露，深圳只有20%左右的电子商务企业能持平或盈利，其面临的命运，与传统企业并没有太大的差别。
统计数据显示，深圳市30%的电子商务企业注册当年就会死亡，30%的企业在注册三年后死亡，只有不到四成的企业能够成活下来。
B2C的艰难背后，是传统企业触网的力度不断加强。
“我国电子商务已从基础网络、平台、建设、人气积累，进入规模应用阶段。
谁先应用，谁先受益。
2009年-2013年是中小企业网络崛起的最好的机会窗口。
”被称为“中国网络营销教父”的单仁称，拥有品牌、资金、人才和渠道优势的巨型企业一旦全面走向网络，传统中小企业的机会窗口就慢慢关掉了。
“传统企业正面临网络转型的紧急关口，再不发力，注定将很快被新兴网络企业打败。
”单仁表示，在未来十年的全球商业竞争中，网站，而不是办公大楼，将成为一个全球化企业最重要的标志和最重要的资产。
人才和观念依然是两大短板对于广大中小企业来说，要真正掌握网络营销，有面临最大的两块短板，那就是人才和观念。
深圳市市场监督管理局电子商务监管处副处长冯念文称，目前不少电子商务企业难以做大甚至难以生存，人才极度匮乏也是其中一个重要的因素。
“懂商务的人不懂电子，而懂电子的人不懂商务。
如何培养合适的电商人才是发展电子商务的当务之急。
”而另一方面，不少企业主认为，只要做个网站，买个百度竞价排名，就能做网络推广和电子商务了。
而一旦发现通过这些手段没有什么效果，不少企业主的积极性又大打折扣，消极退缩到传统市场上。
单仁表示，要克服上述两大短板，就必须大力发展第三方的、系统的、对企业家和营销主管的电子商务培训体系，抢占第三方人才培训制高点。
记者获悉，为辅助中小企业进行网络营销，深圳市科工贸信委已确定，今年将采取电子商务大讲堂的形式，定时对相关从事电子商务的个人和企业，进行有针对性的培训。
观点中国电子商务协会网络营销推广中心主任单仁网络要“去中间化”小店主和大型B2C平台的网络零售，并非中国电子商务的主流。
中国电子商务大发展的真正未来，在于数千万传统企业走向网络，在于拥有成熟产品和一定员工规模的传统企业向互联网营销转型。
随着人民币升值、成本不断上涨的无法阻挡的趋势，未来国内企业在开展对易的时候，必须通过网络“去中间化”，直接对接国外、建立网络营销平台，才能获得理想收益。

Zeiss Vario-Sonnar 35-70mm f3.5-5.6镜头
Zeiss Vario-Sonnar 35-70mm f/3.5-5.6焦长：35-70mm（实测35.11-71.23mm）光圈：最大f/3.5-5.6（由于设备限制无法测量实际光圈），最小f/22-32镜片结构：13片8组视角：对角61°-32°焦长刻线：35-，50-，70mm变焦操作：逆时针旋转变焦环70度至35mm端最近对焦距离：100cm镜身规格：长度最短54mm（连镜后突出部分70mm），最长84mm，直径59mm 重量：308克滤镜尺寸：46mm螺纹可供卡口：康太时G2 附件：软套定价：定价1500美元（美国市场参考零售价999美元）外观与操作：这支独特的镜头可以在康太时G2上提供35-70mm焦长的连续变焦，但是在康太时另一款可换镜头的自动对焦旁轴相机G1上，这支镜头却无法正常使用。
该镜头在G2相机上使用时，取景范围和镜头变焦连续同步。
该镜头十分小巧，不过由于采用坚实的金属结构，对这样规格的镜头来说相对略重。
钛金属表面磨砂处理，十分漂亮。
带棱纹的变焦环提供了很好的握持性，在任何位置均没有滑动现象，但操作起来吃力，阻尼不佳。
邻近变焦环的是带棱纹的光圈环，和变焦环十分相似，以至于使用者经常会搞混。
自动对焦快速平稳，相对安静。
手动对焦通过康太时G系列机身上的控制轮进行，所以镜头上没有手动对焦环。
焦长数值和光圈数值（光圈整档处有定位感）为黑色，明显易认。
镜头不用时须置于35mm位置，不管是在相机上还是单独保存。
测试情况：由于该镜头尾部突出部分特别长而窄，我们的SQF值测试仪器无法辨读画面的边缘及像场弯曲情况。
解像率测试显示这是一支非常锐利的镜头，我们测试的三个焦长段，其结果均媲美高质量的定焦镜头。
35mm处有轻微的桶形畸变（0.75%），50mm处有可察觉的枕形畸变（1.15%），70mm可见轻微的枕形畸变（0.55%）。
焦平面曝光精确度除35mm处最大光圈时由于四周光量下降呈1/2档欠曝外，其余所有焦长和光圈下约2/5档欠曝。

lf35锡球成分
lf35锡球成分
LF35是一种常用的锡球焊料，其成分主要包括锡（Sn）和铅（Pb）。
具体的成分比例会根据不同的制造商和产品而有所差异。
一般而言，LF35锡球的成分含量为约63%的锡和约37%的铅。
举例来说，如果一颗LF35锡球的总重量为10克，其中大约有6.3克的锡和3.7克的铅。
这种比例的锡球在电子焊接中被广泛用于电路板组装和元器件连接，具有良好的焊接性能和可靠性。
需要注意的是，由于铅的环境和健康风险，越来越多的焊接行业已经开始采用无铅焊料替代LF35锡球。
因此，在使用焊料时，应该根据实际需求和相关法规来选择适合的材料。

SIGNAL ANALYZERSDual-Channel, Dynamic Signal Analyzer 244 pHz to 102.4kHz Model 35660A•Network and spectrum analysis. 102.4kHz single channel measurements. 51.2kHz dual channel measurements. 401 line resolutionHP 35660A Dual-channel Dynamic Signal Analyzer The HP 35660A Dynamic Signal Analyzer is an FFT-based instru-ment that provides spectrum and network measurements in electron-ics,mechanical test, acoustics, and other low frequency application areas. The analyzer also offers built-in test and automation features,traditionally available only with a computer. These features includean internal programming language (HP 35680A Instrument BA-SIC), a built in disc drive, limit testing and data tables. With automa-tion built in, the HP 35660A can save you both time and money.The HP 35660A performs spectrum analysis from 488Allz to 102.4kHz and network analysis from 244AI Iz to 51.2 kHz. The FFT provides 401 lines of resolution in both one- and two-channel modes. Complete alias protection and digital zoom ensure high resolution mea-surements with warranted accuracy. Measurements include linear spec-trum, power spectrum, frequency response, gain/phase, group delay, ti me history, and power spectral density. A built-in 3.5 inch disc drive, compatible with HP Series 200/300 workstations, stores traces, tables, states, and application programs.Electrical Spectrum AnalysisThe HP 35660A is typically 10 to 100 times faster than swept spec-trum analyzers for equivalent measurements, and provides higher res-olution(?444H7.throughout the102.4kHz frequency range). This speed and resolution contribute to the quality of HP 35660A tests for distortion, spur level, frequency drift, intermodulation, and other sig-nal parameters. Amplitude accuracy of t0.5 dB and frequency accu-racy of t30 ppm guarantee precision in tests of such devices as headsets, modems, telephone components, speakers, transducers, and electrical motors.Electrical Network AnalysisWith two input channels and a built-in source, the HP 35660A canquickly measure the response of low-frequency filters and networks.Source signals provided are random noise, periodic chirp, and fixedsine. Periodic chirp is useful for testing non-linear responses such asoutput clipping of amplifiers. Random noise is ideal to get a linearapproximation of a non-linear network. Fixed sine lets you test re-sponse at a specific frequency..70dB dynamic range•f0.5dB amplitude accuracy•f0.4dB and f 1.0 degree channel match. Frequency accuracy of t30 ppmThe HP 35660A is also a good choice for low-frequency transmis-sion measurements in telecommunications and other areas. To ensure highly accurate magnitude and phase measurements, the HP 35660A offers t0.4 dB gain and f1.0 degree input channel phase match. For custom analysis of these measurements, the HP 35660A provideswaveform math, including conjugation, FFT, inverse FFT, square root, and frequency domain integration and differentiation.Machinery VibrationThe HP 35660A is an excellent fit for applications that require vi-bration monitoring at full load. With the analyzer's built-in limit ta-bles, users can implement vibration and health monitoring of engines, machine tools, and other equipment, without an external computer and without programming. The analyzer's internal disc drive makes it easy to record, store, and recall limits for production or maintenance testing.1981Structural AnalysisThe HP 35660A uses force and exponential windows to perform frequency response testing of mechanical devices and ing HP Instrument BASIC, the analyzer can simplify data collec-tion for your modal surveys. Fot complete modal analysis, you can choose from several third party modal packages.AcousticsAnother major application area for the HP 35660A is acoustics and noise measurements. This includes testing for room and device responses, noise identification and level, and underwater acoustic tests such as sono-buoy and sonar transducer testing. Acoustic inten-sity measurements are available with third party software.Limit and Data tables for fast, consistent resultsSpectrum and network analyzers are frequently used to test signals and device response against certain specifications. The HP 35660A i mproves this process by providing built-in limit testing. A limit line defines acceptable minimum and maximum values at specific X-axis points (in both time and frequency domains). Users can specify an upper and lower limit for every point in the trace, as well as specifying acceptable bands and slopes. During a test, the HP 35660A checks the trace level against the limit lines, then displays PASS or FAIL on the screen. Limit testing is especially powerful when used with HP Instrument BASIC. For example, a program can quickly pull limit lines of disc and use them as a reference against a series of traces.Data tables are another key feature of the HP 35660A. A data table eliminates the need to move markers along a trace to read multi-ple values. This is particularly useful for such applications as noise level monitoring at multiple frequencies. Enter up to 400 X-axis loca-tions in a data table, and the HP 35660A fills in the table with a Y-axis value for each X entry. You can display, print, or store a complet-ed table. For repeated measurements, you can create a unique table for each test and quickly recall each table from disc.In addition to data tables and limit testing, the analyzer includes extensive markers to highlight harmonics and sidebands and to search for minimum, maximum, and target values.HP-113System ControlWhen used with HP Instrument BASIC, the HP 35660A can serve as a test system controller. A system might include peripherals such as hard discs, printers and plotters, as well as other instruments such as switch matrices, voltmeters and signal generators. You can auto-mate smaller systems without the cost of an external computer, while conserving rack or bench space.HP 35680A Instrument BASICTo simplify automation and test analysis, the HP 35660A includes a powerful new feature: a subset of HP Series 200/300 BASIC run-ning inside the analyzer. HP 35680A Instrument BASIC adds deci-sion-making, branching, I/O including control of other instruments,and custom user interfaces. IIP Instrument BASIC is fully syntax-compatible with HP BASIC, so current IIP workstation owners can easily merge the HP 35660A and HP Instrument BASIC into their test systems.A Language for Programmers and Non-Programmers With over 150 BASIC commands, HP Instrument BASIC is a powerful tool for programmers. But it also includes a feature that makes it easy for non-programmers to automate analyzer functions.Keystroke recording automatically creates a program as the user makes measurements from the front panel. An entire test sequence can be recorded and saved with no programming required.HP Instrument BASIC programs can be developed on an HP 9000Series 200/300 BASIC workstation and then transferred to the ana-lyzer via a 3.5 inch floppy disc (files must be saved in LIE format).Programs developed on the HP 35660A will also run on a worksta-tion. If desired, the analyzer portion of a computer-aided test (CAT)can be created with keystroke recording, then merged with the main program written on an external computer. The HP 35660A is also fully IIP-IB programmable from an external computer, using any language you choose.Custom solutions with the HP 35660AApplications that involve long and repetitive testing can benefit sig-nificantly from custom solutions available with the HP 35660A. For example, in a production environment, HP Instrument BASIC pro-grams can automatically recall test setups and prompt a technician for date, time, and other important information. Limit testing can quickly indicate the presence of spurs or undesired harmonics. Opera-tor interaction is further reduced with routines that automatically catalog results to a printer/plotter or to disc.The HP 35681A Analysis Pack provides examples of how to cus-tomize the HP 35660A for specific applications. The Analysis Pack is a set of network and spectrum application programs that enhance the power of the HP 35660A analyzer.Written in IIP Instrument BASIC, the Analysis Pack provides sev-eral ready-to-use application tests, including distortion testing, filter parameter testing, and modulation and peak analysis. The Analysis Pack shows how easy it is to customize tests and provides a set of tested, documented routines you can re-use in your own custom appli-cations.SIGNAL ANALYZERSDual-channel, Dynamic Signal Analyzer 244,uHz to 102 kHzHP 35660AHP 35660A SpecificationsFrequencyMeasurement Range: Channel l: 488pHz to 102.4kHz,single channel mode.
