Benefit of this modified shape is that the expansion around the first corner reduces the initial pressure coefficient on the frustum to low values . 这个改进的外型的优点是绕第一角点的膨胀会把截锥上的初始压力系数减少到很低的值。
Code for initial pressure testing of collapsible soils 湿陷性土起始压力测试规程
Methodology for the initial pressure and the hydrodynamic system in hydrocarbon reservoirs 油气藏原始地层压力及压力系统确定方法
Effect of initial pressure on characteristic parameters of detonation wave in pde pulse detonation engine 混合气体燃烧中压力对爆震波特性参数影响研究
Check initial pressure to see if full intended line pressure is applied at the valve inlet 检查初始压力,看看是否全部预设管道压力是否应用在阀门进口处。
After initial pressure differential reading is taken , refer to flow rate charts to obtain flow rate based on pressure differential and valve setting 在获得初始压差读数后,参阅根据压差和阀门设置而得的流量表。
The handles have to be pressed and released by hand a few times . as result an initial pressure within an area from 0 to 16 bar or - 780 to 0 mbar is produced 把柄要用手握紧释放多次,这样就能产生最初压力,范围在0到16 bar或- 780到0 mbar 。
Fenves " 3 - d joint element modei and its constitutive relations are demonstrated and used to simulate the opening , closing and sliding of joints , and the initial pressure and tensile strength at the interface 论述了三维fenves缝单元模型及缝单元的本构关系,可用以模拟横缝的张开、闭合和滑移,并可考虑缝面的初始压力和抗拉强度。
In experiments , an entire process from occurrence of the attenuation to the onset of the overdriven detonation is captured by using smoked foil records and the experimental relationships between the re - intension length and the initial pressure are also got 该非稳定爆轰波传出声学吸收段后再次加强,并在距声学吸收段出口端一定距离处突然发展成超驱动爆轰。
The paper calculates and analyzes the influences of the initial pressure , the volume of the expansion chamber , and the throat diameter of the nozzle on the non - loaded performance of the circuit breaker , and presents the variation of the state parameters of the expansion volume and the flow field during interruption period , also predicts the nature of the self - extinguishing circuit breaker 本文分析计算了起始压力、膨胀室体积及喷口喉部直径的变化对断路器空载特性的影响,给出了断路器膨胀室状态参数及灭弧室内气流场在断路器开断过程中的变化,得到了自能式sf _ 6断路器固有的特性。
