中碳钢
中碳钢中碳钢medium carbon steel碳量0.25％～0.60％的碳素钢。
有镇静钢、半镇静钢、沸腾钢等多种产品。
除碳外还可含有少量锰(0.70％～1.20％)。
按产品质量分为普通碳素结构钢和优质碳素结构钢。
热加工及切削性能良好，焊接性能较差。
强度、硬度比低碳钢高，而塑性和韧性低于低碳钢。
可不经热处理，直接使用热轧材、冷拉材，亦可经热处理后使用。
淬火、回火后的中碳钢具有良好的综合力学性能。
能够达到的最高硬度约为HRC55(H B538)，σb为600～1100MPa。
所以在中等强度水平的各种用途中，中碳钢得到最广泛的应用，除作为建筑材料外，还大量用于制造各种机械零件。
中碳钢的焊接中碳钢含碳量比低碳钢高，强度较高，焊接性较差。
常用的有35、45、55号钢。
中碳钢焊条电弧焊及其铸件焊补的主要特点如下：(1)热影响区容易产生淬硬组织。
含碳量越高，板厚越大，这种倾向也越大。
如果焊接材料和工艺规范选用不当，容易产生冷裂纹。
(2)由于基本金属含碳量较高，所以焊缝的含碳量也较高，容易产生热裂纹。
(3)由于含碳量的增高，所以对气孔的敏感性增加。
因此对焊接材料的脱氧性，基本金属的除油除锈，焊接材料的烘干等，要求更加严格。
低碳钢低碳钢(low carbon steel)又称软钢, 含碳量从0.10％至0.30%低碳钢易于接受各种加工如锻造, 焊接和切削, 常用於制造链条, 铆钉, 螺栓, 轴等。
碳含量低于0.25％的碳素钢，因其强度低、硬度低而软，故又称软钢。
它包括大部分普通碳素结构钢和一部分优质碳素结构钢，大多不经热处理用于工程结构件，有的经参碳和其他热处理用于要求耐磨的机械零件。
特性低碳钢退火组织为铁素体和少量珠光体，其强廖和硬度较低，塑性和韧性较好。
因此，其冷成形性良好可采用卷边、折弯、冲压等方法进行冷成形。
这种钢翅具有良好的焊接性。
碳含量很低的低碳钢硬度很低，切削加工性不佳，淬火处理可以改善其切削加工性。

Electro-proportional relief valve - pilot capacity, high pressure setting with no commandCapacity: .25 gpm (1L/min.)Model: RBANProduct DescriptionThis 2-port, pilot-stage, direct-acting relief cartridge is an electro-proportionally controlled, normally-closed pressureregulating valve. The valve is spring biased closed to its highest setting (customer specified). Increasing current to the coil will proportionally decrease the pressure setting. When the pressure at port 1 (inlet) is sufficient to overcome the springforce minus the solenoid force, as determined by the analog input signal, the poppet lifts and allows flow from port 1 to port 2 (outlet). This pilot control cartridge utilizes the T-8A cavity so it can be used in conjunction with Sun's main stage, pressure control elements.Technical FeaturesCustomer must specify a relief setting that falls within the selected pressure range. This setting represents the maximum relief pressure which the valve will default to with no command. As the command increases, the relief setting will decrease. See performance curves for selected pressure range. This setting is not adjustable in the field. Damped construction provides stable operation over a wide range of operating conditions.Varying the analog input signal to the proportional solenoid provides a step-less control of pressure.Low leakage levels in the closed position. (Reseat occurs at 85% of cracking pressure.)This electro-proportional cartridge utilizes the Sun T-8A, 2-port cavity making it the ideal choice to use in conjunction with Sun's main stage cartridges. Separate pilot lines are eliminated and only one cavity needs to be machined to accommodate both the control and primary function. Note: All 2-port pilot stage control cartridges utilize the same cavity and are physically interchangeable. Functionality is the only consideration. Coils are interchangeable with Sun's other full flow, solenoid operated valves and can be mounted on the tube in either direction.Note: The main stage valve should first be installed to the correct torque value followed by the T-8A pilot control section into the main stage valve to its required torque value.For optimum performance, an amplifier with current sensing andadjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.High pilot capacity allows for operation of larger size main stage elements.Incorporates the Sun floating style construction to minimize thepossibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.DownloadRBAN-XAN-***Control Adjustment Range Seal Material CoilStandard OptionsX*No Manual Override Standard OptionsA3000 - 1500 psi (105 - 210bar)B1500 - 800 psi (55 - 105 bar)D800 - 300 psi (20 - 55 bar)W4500 - 3000 psi (210 - 315bar)Standard OptionsN Buna-NV Viton***See Coil Options BelowStandard Coil Options (View All)DIN 43650 3 pin(Hirschman)SAE J858A AMP Junior Timer Twin Lead Metri-Pack Deutsch DT04-2P *** no coil 612AMP Junior Timer 12 VDC 812Metri-Pack 12 VDC212DIN 43650 3 pin(Hirschman) 12 VDC624AMP Junior Timer 24 VDC 824Metri-Pack 24 VDC224DIN 43650 3 pin(Hirschman) 24 VDC712Twin Lead 12 VDC 912Deutsch DT04-2P 12 VDC524SAE J858A 24 VDC 724Twin Lead 24 VDC 924Deutsch DT04-2P 24 VDC Embedded Coil Options (Click Here)2B12A DIN 43650 3 pin(Hirschman) commandcommon on fourth pin 12VDC 0-20 mA 2C24V DIN 43650 3 pin(Hirschman) +5V referenceon fourth pin 24 VDC 0-10V4A12A Deutsch DT04-6P allfunctions enabled (separatecommand common, 5 vreference, and an enable) 12VDC 0-20 mA2B12V DIN 43650 3 pin(Hirschman) commandcommon on fourth pin 12VDC 0-10V 2D12A DIN 43650 3 pin(Hirschman) enable input onfourth pin 12 VDC 0-20 mA4A12V Deutsch DT04-6P allfunctions enabled (separatecommand common, 5 vreference, and an enable) 12VDC 0-10V2B24A DIN 43650 3 pin(Hirschman) commandcommon on fourth pin 24VDC 0-20 mA 2D12V DIN 43650 3 pin(Hirschman) enable input onfourth pin 12 VDC 0-10V4A24A Deutsch DT04-6P allfunctions enabled (separatecommand common, 5 vreference, and an enable) 24VDC 0-20 mA2B24V DIN 43650 3 pin(Hirschman) commandcommon on fourth pin 24VDC 0-10V 2D24A DIN 43650 3 pin(Hirschman) enable input onfourth pin 24 VDC 0-20 mA4A24V Deutsch DT04-6P allfunctions enabled (separatecommand common, 5 vreference, and an enable) 24VDC 0-10V2C12A DIN 43650 3 pin(Hirschman) +5V referenceon fourth pin 12 VDC 0-20mA 2D24V DIN 43650 3 pin(Hirschman) enable input onfourth pin 24 VDC 0-10V4F12V Deutsch DT04-6Pprogrammable ramps,separate rise and fall 12VDC 0-10V2C12V DIN 43650 3 pin(Hirschman) +5V referenceon fourth pin 12 VDC 0-10V 2F12V DIN 43650 3 pin(Hirschman) programmableramps, separate rise and fall12 VDC 0-10V4F24V Deutsch DT04-6Pprogrammable ramps,separate rise and fall 24VDC 0-10V2C24A DIN 43650 3 pin(Hirschman) +5V referenceon fourth pin 24 VDC 0-20mA 2F24V DIN 43650 3 pin(Hirschman) programmableramps, separate rise and fall24 VDC 0-10VAdditional Options (Click Here) Additional Coils512SAE J858A 12 VDC 71299Twin Lead to Deutschconnector, 9 inch lead length 72499Twin Lead to Deutschconnector, 9 inch lead lengthStainless options not available for this model* Special Setting required, specify at time of orderCopyright © 2002-2012 Sun Hydraulics Corporation.

D这是我做实验的过程中的胰酶配制方法：:D
0.25%胰酶溶液的配制：
1.称取1:250 （或1：125）的胰酶粉末0.25g（Sigma产品）
2.先用少许灭菌过的D-Hank's液或PBS（不含Ca离子，镁离子均可）调成糊状
3.然后补足到100ml。
4.置室温用磁力搅拌器搅拌4小时或4℃冰箱内过夜
5.过滤灭菌，分装成5-10ml小瓶，-20℃保存备用。
