EDV, ESV, and LVEF were calculated using Simpson's rule algorithm for monoplane LV angiography, using M-mode method for two-dimensional echocardiography.

左室造影采用单平面法(辛普森法则)，二维超声心动图采用M型超声获得EDV、ESV和LVEF。

This paper presents a new type of Electronic Servo valve (ESV) which includes the pulse width modulator, electro-mechanical actuator and variable section area valves.

本文介绍了一种新型的电子伺服活门。它由脉冲调制器和机电作动器以及变截面活门组成。

Furthermore, it proves MSPV is the final extension of safety vectors (SV) and extended safety vectors (ESV), which also use the vectors to record the optimal paths in hypercube multi-computers system.

与基于安全向量及扩展安全向量的容错路由算法相比，MSPV是SV以及ESV的最大扩展，解决了如何用向量的形式来记录最多最优通路的问题。
