好的，现在我要画一张图代表什么是…这是代数，什么是几何，这张图代表了什么？

Ok, now I wanna draw a picture that represents what's this, this is algebra, what the geometry, what's the picture that goes with it?

由计算结果可以得到，几何非对称结构对多频率段降噪效果好，而改变壳面的曲率半径对壳的固有频率提高较大。

Based on results, the geometrical asymmetry shell has obvious effect about reducing noise in large range of frequencies, and change radius of curvature can increase eigenfrequency obviously.

对于径向分辨率好或高的测量结果而言，其径向微分几何因子在与仪器一定距离的位置有一个尖峰。

A measurement with good or high radial resolution will have a sharp peak in the radial differential geometric factor at some distance from the tool.

The length of a line segment?

好，几何学是怎么说的来着？

So, we should use that, but people in finance resist using that because it's a lower number and when you're advertising your return you want to make it look as big as possible.

所以我们应该用这个指标,但金融界反感使用几何平均,因为它比其他平均数都来得小,他们为自己的收益率做广告时,当然希望数字越大越好
