Let x be an immersion of a compact Willmore surface M into the n-dimensional unit sphere Sn. In this thesis we first consider the Willmore surfaces in the unit 3-sphere, and establish an integral inequality for the square of the length of the trace free part of the second fundamental form and the mean curvature.

Exposure time and distance of the light into a square, our experience shows that if the lights distance, you will need to increase the exposure time of Chapter 3, section; on the other hand, if you zoom out, 100% exposure time light spacing should be reduced to a quarter of the original.

曝平工夫与灯距成平方干系，教训表明，如果灯距补充1倍，曝平工夫则需给补充3倍；反之，如果放不小1倍灯距，曝平工夫答加为本来的四不合之一。

The optimal process conditions are that the weight ratio between the adhesive and turquoise powder is 1:4. The size of the particles is no less than 250 eyelet. The pressure is 1.5×10^4~3.0×10^4MPa/m^2. Then after self-hardening at room temperature for 1~2 days, the turquoise body should be heated for solidify with a certain temperature curve.

实验效果最佳的工艺条件为：胶粘剂的质量与绿松石粉料的质量比例为1：4，绿松石粉体粒度不小于250目，加压压力为1.5×10^4~3.0×10^4MPa/平方公尺，在室温下自硬化1~2d后按照一定的恒温曲线进行加热固化。

Firstly got the sequence of the contour points with one pixel width of the image to be assembled.

首先求出待匹配图像单像素宽的轮廓曲线上像素点的坐标序列，然后利用轮廓上各点和与其相差六个点的像素点之间的位置关系及行列坐标差的平方代数和对轮廓进行表示，得到两轮廓曲线的表示序列后；接着采用寻找两轮廓表示序列的最长公共子序列的方法进行匹配，并在匹配过程中引入了"断点续配"的概念，有效提高了算法的容错性。
