极惯性矩 [
jí guàn xìng jǔ]
[力] polar moment of inertia
- 最大的切应力和所加扭矩成正比,与截面的极惯性矩成反比。
the maximum shearing stress is proportional to the applied torque and inversely proportional to the polar moment of the cross section. - 特征提取是葡萄干等级检测的基础,该文在研究极惯性矩计算长短轴方法的基础上,提出一种利用数值微分法进行长短轴检测的新方法。
Based on studying the way of polar moment of inertia, a new method of major and minor axis detecting by DDA was provided.
