The approach of solving mean curvature,Gaussian curvature and principal curvatures of general triangular mesh model was derived.Considering coarse triangular mesh model is often seen,in order to increase the precision of curvatures,combined with Loop subdivision algorithm,the curvature algorithm was further extended.

推导了一般三角形网格模型顶点的平均曲率、高斯曲率和主曲率的计算方法，考虑到经常遇到粗糙三角形网格模型，为提高其曲率计算方法的精度，结合Loop细分曲面算法，进一步拓展了该曲率计算方法。

Aiming at the problem of coarse footmark surface with severe noises, based on the in-depth analyzing geometrical relationship and differential characteristics of the three-dimensional footmark impressing surface, we propose a principal curvature and principal direction based impressing surface segmentation algorithm and a multi-scale fusion algorithm to segment the stereo footmark.

针对立体赤足迹表面粗糙、噪声严重的特点，深入分析立体足迹三维表面的几何关系和微分特性，提出了基于曲面主曲率和主方向的立体足迹压力面分割算法和多尺度融合算法，分割结果理想并与领域知识吻合。4。

First we compare rough sets and random sets,and derive the relationship between belief function and lower probability.

This Procrustean approach, whatever merits it may otherwise have, cannot possibly do full justice to Chinese culture as an indigenous tradition.

这种粗糙套用的模式，不管它有什麼优点，都不可能充分阐述具有地域性传统的中国文化。

Not only are you slower (even if your rim isn't rubbing against the brakes, its out-of-round profile causes more drag and friction), but the ride is rougher, you have less control, and you could end up on the ground if the wheel folds or a spoke breaks thanks to the pressure of uneven spoke tension.

你不仅会骑的很慢（即使你的车圈没有和刹车发生摩擦，车圈脱离圆轨的摆动也会造成更多的阻碍），而且由于车圈是粗糙的，你将减少对其控制，而由于条幅受到不均等的拉力，你最终将以车圈扭折或条幅断裂为结局。

It is discussed how to eliminate the system error of the optical profiler to measure the supersmooth optical surface.

讨论了如何确定及消除光学轮廓仪的系统误差，进而测定超光滑光学表面粗糙度的方法及结果。

I met a profiteer, he pointed to work a rough state of the motherboard that a well-known domestic manufacturers of PC motherboards is that the motherboard manufacturers to the OEM.
