脈動率的英文怎麼說

What is mainly discussed in this dissertation is as follows : the fault mechanism and vibration frequency feature of hydroelectric vibration are analyzed, induced and reorganized. the select and placement of detecting positions of parameters such as vibration, swing and pressure pulsation are researched, and the corresponding sensors are selected to monitor

本文主要進行了以下工作：分析、歸納和整理了水電機組振動的故障機理和振動頻率特徵，對機組的振動、擺度和壓力脈動測點進行了選擇和布置，並選用相應傳感器進行監測。

Thrust fluctuation ratio

推力脈動率

In addition, a calculating method of parametrically designing hydraulic motor with non - circular planetary gear is proposed aiming at maximal unit displacement and the minimal pulsation ratio by means of visual c + + 6. 0 software

此外，探討了以單位體積排量最大為設計目標，流量脈動率最小為約束條件對非圓行星齒輪液壓馬達的參數化設計方法。

Secondly, based on the research of flow characteristic of hydraulic motor with multi cylindrical gear, optimal conditions of tooth number are got to minimal the pulsation ratio of motor in the design of hydraulic motor

其次，通過對圓柱多齒輪式液壓馬達的流量特性進行研究分析，得出使其排量脈動率最小所必須的各齒輪齒數應滿足的設計準則。

Then a formula about flow of the gear pump and the coefficient of engagement overlap to find is obtained by area method. through analysis contact ratio and overlap ratio has the effect on the volume oil and the flow pulsating ratio

然後採用面積法求得齒輪泵流量與齒輪嚙合重合系數的關系式，研究了齒輪嚙合重合系數對齒輪泵困油和流量脈動率的影響。
