再计算

What we needed was (1) geometry based subdivision,(2) reasonable number of quadrilaterals, and (3) very low computational cost.

我们需要的是：（1）基与几何的再分，（2）合理的四边形数量，（3）非常低的计算成本。

The method first embeds watermark into the geometric invariant Fourier-Mellin domain of an image to weaken the geometric distortion, brought by printing process, of the watermark in presswork, and the image is then used to create presswork via a legal printing process. Secondly, the method rectifies rescanned image from the presswork by using Radon transformation and the embedded watermark in it is detected. Since there is an obvious difference between the destruction degrees of the watermark caused respectively by legal and pirated printing process, we can judge whether a copy of presswork is valid or not just by computing the ratio of the successfully derived watermark and comparing it with a predefined threshold.

该方法先将水印嵌入到具有几何不变性的Fourier-Mellin域中，以削弱正版印刷过程中的几何失真对水印的破坏；再利用Radon变换对由扫描印刷品所获得的图像进行矫正，并从图像中提取嵌入的水印信息；由于正版和盗版印刷过程对水印的破坏程度区别明显，该方法最终通过计算水印提取的正确率来度量这种破坏，并将其与预先制定的阈值进行比较来判定印刷品的正伪。

First thought is to want to look for a function, appoint the width of the picture and height directly, geometric ratio exemple cuts, the result was not found, can use calculative earth method only, again conveniently used Transform function, after having Crop, need not pass into width and height, feel they are a bit redundant.

最初的想法是想找一个函数，直接指定图片的宽度和高度，等比例剪切的，结果没有找到，只能使用计算的土办法，再随手使用了transform函数，有了crop以后，就不用传入宽度和高度了，感觉他们有点多余了。

The results calculated show that the major contributions for the backscattering cross section come possibly from average cloud diameter, clear-air and humidity turbulence and also from distributions of cloud particles, especially, at higher frequencies.

再分析了云的后向散射机理，计算了西安地区云的后向散射截面；表明影响云的后向散射截面的主要因素为云滴平均半径、大气湿度湍流及云粒子分布，在较高频率时更显著。

Since the approach has been coded into the program, if it can be combined with the predication system of the nautical almanac data, the combined two systems can be further developed in a commercial package and dramatically improve the training or education of the current celestial navigation.

本法因已将理论透过数值计算，若能再结合航海历资料库预测系统，未来将可进一步发展成商用套装软体，改善目前商船教育训练或海上实务作业上天文航海的现况。

Based on Fermat's principle and light path function, it gets the spectral distribution of the incident rays, and it can get the ray tracing map through a matrix method.

在费马原理的基础上利用光程函数法得到入射光通过光栅后的光谱分布情况，再使用传输矩阵的计算方法构造出光谱的点列图。

Employing the Nernst Equation the electrode potential of any possible corrosion galvanic cell may be calculated.

本文作用的方法是基于Nernst方程计算出可能形成的电极电位，再根据电位的高低判断出可能的氧化剂，从而分析出金属腐蚀的原因。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
