Then, the method to estimate cavitation erosion characteristic of high pressure piston plunger pump by analyzing impingement angle on outlet of throttling groove is put forward. That is, to hold the impingement angle range of 30°～60°as appraisal criterion of cavitation erosion characteristic on high pressure hydraulic plunger pump.4 The throttling characteristic of hydraulic control valve is studied by CFD calculation and experiment.

最后，提出了一个通过分析节流槽出口处的射流方向来评价高压轴向柱塞空蚀特性的空蚀评价方法，即将节流槽出口的射流角范围30°～60°作为评价高压轴向柱塞泵空蚀特性的标准。4对液压控制阀的节流特性进行了CFD数值计算和试验研究。

When plunger running, for the centrifugal inertial force brought by crankshaft and impact inertial force generated by repeated running of plunger piston, the high power vibration and noise appear.

柱塞泵在运转过程中，主要由于曲轴产生离心惯性力和柱塞来回运动产生惯性冲击力，会产生较大的振动和噪声。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
