Furthermore, the influences of all inlet parameters of expander, evaporator pressure and nominal load on expander efficiency are analyzed by simulation. 另外,理论模拟研究膨胀机各进口参数、蒸发器压力和负载对膨胀机效率的影响。
The Nominal Design Pressure and the Nominal Working Pressure of Gas Appliances 燃具设计额定压力(PN)与工作额定压力(PN)
In certain flow field structure, obtained the linear regression equation of pressure compensating emitter nominal flow and elastic membrane of thickness and hardness. Guiding significance for development of pressure compensating emitter. 在一定流道结构形式下,得到压力补偿滴头标称流量与弹性膜片厚度和硬度之间的线性回归方程,对于压力补偿滴头的开发有一定的指导意义。
Before each start, the air source pressure shall be checked to be within nominal range and cooling water shall be checked to be under normal flowing. 每次开机前应检查气源压力是否在额定值范围内,冷却水是否正常。
China has seemingly resisted years of US pressure to revalue the renminbi and the pace of nominal revaluation remains low. 多年来,中国似乎抵制了美方要求人民币升值的压力,人民币兑美元的名义升值速度仍然很慢。
