rate of pressure rise

In water supply system works, flow rate suddenly changing in pressure piping that create pressure of stream current steep rise or sudden drop, which is also called water hammer or hydraulic transient.

水力过渡过程（或水锤）是指，在供水工程中由于压力管路中流速的突然变化，引起管路中水流压力急剧上升或降低的现象。

CNG DI engine gave low value of the maximum rate of pressure rise.

天然气直喷发动机的最大压力升高率低.

Dihydralazine increased HR and myocardial tension-time index per minute at 15 min after medication in conscious rabbits, but the maximum rate of intraventricular pressure rise was not changed. These results suggested that the major cause of increased myocardial oxygen consumption is induced by elevated HR.

兔静脉注射双肼苯哒嗪，心率加快，每分钟心室肌张力&时间指数（TTI·HR）增加，心室内压变化最大速率无改变，提示心率加快是心肌耗氧增加的主要原因。

The results show that, with the increase of DME proportion, inlet pressure increases, but the ignition delays, the peak in-cylinder pressure and heat release rate, peak in-cylinder temperature and peak pressure rise rate decrease, and their phases retard.

研究发现，采用同一喷嘴时，随着燃料中二甲醚比例的增加，发动机进气压力增加，着火延迟，缸内压力峰值、放热率峰值、最高缸内温度、压力升高率峰值降低，其相位延后。

A study on the pressure and rate of pressure rise in energetic material dusts

含能材料粉尘爆炸压力和压力上升速率的研究

Thermal decomposition and thermal stability of expanded ammonium nitrate were studied by accelerating rate calorimeter. Temperature, pressure and temperature rise versus time curves, decomposition pressure and temperature rise versus temperature curves were obtained respectively.

该文利用加速量热仪研究了膨化硝酸铵的热稳定性，得到了膨化硝酸铵的温度、压力和温升速率随时间的变化曲线以及温升速率、分解压力随温度的变化等曲线。
