1 The sealing surface connecting the body flange can adopt the planar type for valves with PN≤2.5MPa; and convexo-concave, tongue

4.2.1 与阀体法兰连接的密封面型式，公称压力PN≤2.5MPa的阀门，可采用平面式；其他压力级应为凸凹式、榫槽式或梯形槽等型式，并在

According to induced response method, the expression in frequency domain of pressure response at the end of pipeline is derived using impulse response method and convolution theorem. The expression indicates that that transfer function is only related to the characteristics of pipeline system and the Fourier transform of flow variable only depends on the operating characteristics, and the pressure response in frequency domain is linear with the Fourier transform of flow variable.

基于激励响应法，应用脉冲响应方法和卷积定理得出了管道末端压力响应在频域中的表达式，此式表明：传递函数只与系统的特性相关，流量变量的傅立叶变换只与操作特性相关，且压力频域响应与流量变量的傅立叶变换为线形关系，根据此式在理论上能够得到管道泄漏点的重要信息。

It's no surprise that being told that pain is stress related feels like an affront, Dr. Muller says.'There's this idea among high-functioning people that 'I'm a good coper,' and these symptoms suggest that you're not,' she says.

确实，如果听到别人说，你的病痛是压力引起的，你会觉得这是一种冒犯，穆勒医生说，"正常人都有一种观念，认为'我能应付压力'，而这些病症表明，其实你无法应对自如。"

Against the background of pressure measurement of the muzzle shock wave, the research work about technology of dynamic modeling and compensation, correlatively to the topic of the dynamic characteristics and its improvement of pressure sensors, is described in detail.

由于肋摩擦的影响，作用在扶壁立板上的土压力与古典的库仑或朗金土压力不同。

HOW: Counterpressure fillers work through a series of valves by sealing the bottle, purging air from the bottle with CO2 pressure, and DIFFERENTIAL BY-PASS BALANCING VALVE EN800X opening a valve to allow the already-carbonated beer to flow from a keg that is also driven by CO2 pressure.

如何：反压灌装机工作，通过一系列的阀门密封瓶，从与清除二氧化碳的空气压力瓶，打开阀门，使已经碳酸啤酒流向1桶，这也是由二氧化碳压力驱动。

According to Crenshaw et al.[1], wide tourniquet cuffs are more effective at lower inflation pressures than are narrow ones. Pedowitz et al.[2] demonstrated that curved tourniquets on conical extremities require significantly lower arterial occlusion pressures than straight tourniquets Fig.

根据Crenshaw[1]等人的研究，充气压力较低时宽的止血带比窄的止血带更为有效：Pedowitz[2]等人证实采用弧形止血带对圆锥形的肢体部分加压时，使动脉闭塞所需的压力比使用直止血带(长方形，straight tourniquet)显著降低(图1—1)。
