孔量 meaning in English

borehole surveying

The method to calculate value of crushing hole in roller chain plate is introduced
给出了计算链板最佳挤孔量的有效计算方法。
At same time we analysed the necessary of reaming after pressing - bushed and found out the deformed law in the hole through a lot of testing
同时分析了压套后铰孔的必要性，经大量试验摸清了套内孔变形规律，确定了预留铰孔量。
Abstract : the factors to influence fatigue life of chain plate areconcluded by experimental methods . the factors to prolong life of chain plate are analyzed by theoretical methods . the maximum value of crushing hole in 16a roller chain plate is calculated by finite element method
文摘:用试验方法确定了挤孔对链板疲劳寿命的影响，从理论上分析了在最佳挤孔量下，链板疲劳寿命提高的因素，用有限元法计算了16a链板的最佳挤孔量，并与试验结果进行了比较。
