This paper introduces the functions of the pressure stabilizer in the pre - acting design of the automatic sprinkler system , and expounds some experiences of maintaining the systemic pressure by selecting the pressure stabilizer 介绍了自动喷水灭火系统预作用设计中稳压装置的作用,阐明了选择稳压装置来维护系统压力的一些体会。
When the system pressure goes up to the value that will open the security valve , the main steam security valve will be released all by itself , discharge the excessive steam in the system and lower down the system pressure 当系统运行压力上升至安全阀的开启压力时，主蒸汽安全阀自行打开，排放主蒸汽系统中的蒸汽，使系统压力降低。
Flow pulsation of hydraulic pumps is the source of pressure and flow pulsation in hydraulic systems . one method to reduce the pressure and flow pulsation of system is to reduce the flow pulsation of hydraulic pumps 液压泵的流量脉动是液压系统存在压力及流量脉动的根源,消除液压系统压力及流量脉动的方法之一是减小液压泵的流量脉动。
Secondly , the specific analysis about the socioeconomic factors is carried out in each section of zhangye oasis . pca indicates that the pressure of the society system , the development of the dynamic economy and the progress of the 主成分分析结果表明，张掖绿洲耕地资源变化主要受社会经济因素中的社会系统压力、经济发展动态和农业科技进步的影响。
The single , iterative run is an attempt to reduce the amount of unpredictable and untargeted kernel code executions that result from the kernel s attempt to load balance the multiple , concurrent runs of the system stress test 单个地、循环地运行，是为了减少在同时运行多个系统压力测试时，内核尝试去平衡它们的负载而导致的不可预知的和无目的的内核代码执行。
So far the mechanism and the effects of developing flow , condensate film roughness , property variation in the gas phase , system pressure , and sorts of noncondensable gases and its contents on condensing are not adequately understood 而且，系统压力、蒸气过热度、蒸气流速和不凝性气体种类及其含量是影响蒸气冷凝的重要因素，这使得蒸气冷凝换热现象大大复杂化。
( 2 ) in the original system because of the area between the piston and the piston pole is too small , the system pressure will rise when in the return stroke . and the reliever valve will open . the return velocity will reduce ( 2 )原设计中，由于活塞和活塞杆的面积差很小，回程上行时，系统压力会迅速升高造成溢流阀的溢流而使回程速度降低，从而降低了系统的工作效率。
The system ' s transfer function is acquired according to the step response curve . the influence of the system ' s pressure balance time affected by the steady and unstable state ' s increasing is discussed , the conclusion has practice meaning 深入客观地探讨了不同的加压速率利加压幅值以及分阶段加压对卸荷阀性能测试系统压力平衡时间的影响，获得了有实践指导意义的结果。
These machines and tools have a rich adjustment merit ability , and his two - way riveting bit , riveting pressure and advance to speed can be transferred to riveting capacity , and system pressure also can be transferred , and fully pledges optimum riveting effect 该机具有丰富的调整功能，其双向铆接位铆接压力进给速度铆接量都可调校，系统压力也可调，充分保证最佳的铆接效果。
According to the principle of absorption , it can cyclicly dry and expel the humidty of the compressed air which comes from aircompressor to adjust the system pressure , the grainy dryer has strong power to absorb the humidity and to regenerate 根据吸附原理对来自空压机的压缩空气进行循环干燥及排除水分(干燥器内的颗粒状干燥剂具有很强的吸附空气中水分的能力及再生能力) ，调整系统压力。
