The root of herbaceous peony still has composed , demulcent , solution is hot , fight phlogistic , fight ulcer , reduce portal vein maximum pressure , reduce serum bilirubin , outspread heart coronary artery , restrain plaque to gather , fight bacterium to fight virus action 赤芍还有镇静,镇痛,解热,抗炎,抗溃疡,降低门静脉高压,降低血清胆红素,扩张心脏冠状动脉,抑制血小板聚集,抗菌抗病毒作用。
The mathematical analysis shows that , with disregarding local head losses and by means of different simplified rigid models , the calculated results of the maximum pressure in a pressurized pipe system containing trapped air mass are equal to and independent of the initial length of the water - column 摘要通过数学分析证明,在不计局部水头损失时,目前常用的几种简化刚性数学模型的最大气压计算结果相等,并与管道内初始充水段长度无关。
Relief valves in the form of the structure and type of moving into straight - pilot , and it ' s up in hydraulic pump export guarantee system , or limitation of the maximum pressure constant pressure , sometimes adjacent to import components in the implementation of the components of its security role 溢流阀按结构形式分为直动型和先导型,它旁接在液压泵的出口保证系统压力恒定或限制其最高压力,有时也旁接在执行元件的进口,对执行元件其安全保护作用。
The system has following functions : showing indicator diagram , the mean value of maximum pressure , maximum pressure raise rate and rotating speed , the distribution of maximum pressure , maximum pressure raise rate and ignition advance angles , the speed fluctuation in cycle , speed fluctuation between cycle and ignition advance angles 本系统可以完成如下的工作:测量摩托车发动机的平均示功图;平均最大压力上升率;平均最高压力;平均转速;点火提前角;最大压力分布;最大压力上升率分布;点火提前角分布;循环内转速波动;循环间转速波动等。
Although the flux per revolution of the optimized pumps is a little smaller than that of tatsuno combined pumps , other characteristics , such as fluctuation rate , maximum pressure angle and velocity fluctuation rate etc , are much better . the methods to cut gears are proposed in the theory for the practical produce in the future 虽然,在体积相等的条件下,优化出来的外圆弧包络线内啮合齿轮泵的排量略小于tatsuno组合泵的排量,但其它性能(如:流量脉动率、最大压力角、速度波动量)都更优。
