In order to improve calibration precision,projection matrixes of camera were obtained by optimization based on Householder orthogonalization transformation which has character of not changing the length of transformed vector.

根据豪斯赫尔德正交变换具有不改变被变换向量长度的特性，采用优化的方法来求得法方程的解析解，得到摄像机的投影矩阵，以提高标定精度。

The results showed that the acid releaser HTA was able to lower the pH values gradually and to increase the levelness without changing the dye fastness.

探讨了释酸剂用量、加入方式以及起始pH值等对锦纶弱酸性染料染色的上染速率和上染率的影响，结果表明：释酸剂HTA能逐渐降低染液的pH值，在不改变染色牢度的前提下，可提高匀染性

Based on transformation thermodynamics analysis, the smaller the grain sizes of melt-spun alloys are, the lower the M is. The melt-spinning technology does not change the crystal structure of the alloy. There exist obvious textures with (400) crystal plane preferential oriented crystal structure in the melt-spun alloys with different quenching rates.

Ni-Mn-Ga合金马氏体相变的热力学分析表明：快淬合金晶粒愈细小，M愈低；快淬工艺不改变合金的晶体结构；在不同淬速的快淬合金中有以(400)晶面为择优取向的织构存在。

The resolution and renaturation efficiency of lysozyme were found to be independent of the flow rate and gradient time when the volume of mobile phase was kept a constant.

在计量置换模型的基础上首次提出了流动相用量估算公式，用实验对其进行了检验，并得出在保持流动相用量不变的条件下，改变流速和梯度时间对分离度和变性蛋白的复性效率影响不大的结论。

Accept certain inalienable truths, prices will rise, politicians will philander, you too will get old, and when you do you'll fantasize that when you were young prices were reasonable, politicians were noble and children respected their elders.

接受一些不可能改变的事实，物价会涨，政客会玩弄权手段，你也会老；当你老时，你会幻想着你年轻时合理的物价，高贵的政客，孩子们对长辈的尊重。

Doctor Liu and his study group hope to follow these isolated and poor schools to study the film effect .He says that film course may be an essential platform to balance the education resources in China.

刘博士他们的课题组，希望跟踪这些偏远贫困的学校，在电影课开展后的作用，他说，也许，电影课能成为中国改变教育资源不平衡的重要平台。

As one of the basic principles of traditional contract law, the principle of contract relativity is changing worldwide, no matter in Continental Law System or in Ordinary Law System, with the development of social economy.

合同相对性原则作为传统合同法的基本原则之一，随着社会经济的发展发生了动摇，这种改变是世界性的，不管是在大陆法系还是在普通法系国家都是一个不争的事实。

In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.

针对有序尺度变量，给出了有序信息系统与有序决策表在优势关系下的粗糙集约简定义；利用粗糙集方法将对象综合排序，进而得到一组秩；根据这些秩，运用非参数统计的思想研究了两个属性子集之间的相关性，并将Spearman秩相关系数作为属性相关性度量；在不改变总体序信息情况下，给出了基于此度量对有序信息系统与有序决策表进行约简的新方法。

The benefit of changing graphics from raster to vector is you do not need to implement anything special for different resolution.
