您要查找的是不是：
- The opening force available is essentially equal to the seat area times the tank pressure. 这个打开阀座的作用力基本上等于阀座面积乘以储罐压力。
- A pilot-operated vent valve for pressure relief uses tank pressure, not weights or a spring, to keep the vent valve seat closed. 先导式通气阀泄压时利用储罐压力，而不是重力或弹簧外力，来保持通气阀阀座关闭。
- High-tech features inside are said to include pressure sensing buttons, combined with backlit glass panels and the retracting transmission selector knob used in the XF. 高科技特点是内据说包括压力传感按钮，加上背光的玻璃面板和旋钮选择撤消传输中使用芳。
- The pressure control system consists of an aft outflow valve, forward outflow valve, pressure controller, control panel, pressure sensing inputs, and monitoring indicators. 压力控制系统包括一个外流阀、前外流阀、压力控制器、控制面板、压力传感器和监视器。
- Verification of the set pressure of a venting device after it has been installed on a storage tank can be accomplished by increasing the tank pressure or vacuum. 通气装置安装到储罐之后，通过增加罐的压力和真空可以实现设定压力的确认。
- A direct-acting vent valve is tightest when tank pressures are 75 percent or less of set pressure. 当罐压力为设定压力的75%25或更低时，直接作用式通气阀有最好的气密性。
- The process uses less fuel and more air to generate power by using advanced technologies, direct injection, electric cam phasing, variable valve lift and cylinder pressure sensing. 该过程使用的燃料和更多的空气来发电用先进的技术，直接喷射，电子凸轮分阶段，可变阀门升程以及缸内压力传感.
- When tank pressures are 90 percent or more of set pressure, seat leakage is common. 当罐压力为设定压力的90%25或更高是，阀座的泄露很常见。
- The process conditions of water solubte pressure sensing acrylic adhesive preparation were studied,and optimum conditions were obtained.The product is featured of safe,less pollution and low cost. 在实验的基础上,研制了水溶型的丙烯酸类压敏粘合剂,并确定了工艺条件。该产品具有安全性好,环境污染小,成本低等优点。
- When pressure drops to 245 psig, a portion of the liquid is passed through a pressure buildup coil which vaporizes the liquid in the coil, and the resultant vapor is sent to the tank's vapor space until a tank pressure of 255 psig is attained. 当压力降到245 psig时，部分液体流过一个压力积累蛇管，蛇管使其内部的液体蒸发，产生的蒸气送到容器的蒸气空间，直到容器压力达到255 psig。
- This force is maximum just before the vent valve opens, so leakage will not occur when tank pressure increases or when tank pressure is kept near the set point of the venting device. 在通气阀打开之前，这一作用力达到最大，所以在储罐压力增加时或储罐压力保持在通气装置设定压力附近时，不会发生泄漏。
- In addition, the nitrogen rich gas is used for fuel tank pressurization during descent. 另外，在飞机降落过程中，富氮气体还可用于油箱增压。
- The objective with this thesis is to build a Black-Box model of the tank pressurization system in JAS 39 Gripen. 燃料电池以其发电效率高及燃料多元之特性，成为最具潜力的新能源技术，其中又以质子交换膜型燃料电池发展最为兴盛。
