主要贡献如下： 1。针对离散情况下Hu不变矩特征仅仅具有平移、旋转不变性，不具有比例不变性的问题，提出了两种改进算法：一种是从图像正方形概念演变而来的归一化中心矩的修正；另一种是重新构造新的不变矩特征。

According to Liu Xie , there is unchangeableness in changes of literary forms or there are changes in unchangeableness . Such a structural theory inspires us to combine structuralist explorations of universality with post - structuralist explorations of changeableness , which may be a scientific and effective approach .

By applying these two tools,we mainly discuss the problems as follows:1 Perturbation identities for the generalized polar decomposition:By applying singular value decomposition, we study the perturbation bounds of the generalized polar decomposition under unitary invariant norms when A is perturbed by addition or multiplication,respectively and give our bounds in identities.2 A class of new unitary invariant metrics: This paper generalized a class of new unitarily invariant metrics and give the upper-bounds and lower-bounds by C-S decomposition.

利用这两个强有力的工具，本文主要讨论了如下问题：1 矩阵广义极分解的扰动等式：利用奇异值分解，本文分别讨论了加法扰动和乘法扰动下矩阵广义极分解在任意酉不变范数下的扰动界，并首次以恒等式的形式给出了酉极因子和半正定因子的扰动界。2 一类新的酉不变度量：本文推广了文[22] 中的结论，定义了一类新的酉不变度量。

Aeruginosa increased with the increased initial P concentration in the media;② Under the constant N concentration, the phosphorus uptake of M. aeruginosa was correlated positively with the initial P concentration;③ Under the constant P concentration, the accumulation of phosphorus by M. aeruginosa was correlated negatively with the initial N concentration, but the trend was not obvious and the effect of initial N concentration on the uptake P quantity became ruleless when the initial N concentration reached a higher level (21 mg/L).

结果显示，①氮磷比不变时，随着起始磷浓度的增加，铜绿微囊藻对正磷酸盐蓄积量也逐渐增加，成明显正相关；②氮浓度不变时，铜绿微囊藻对正磷酸盐的蓄积效果与磷浓度正相关；③而同一磷浓度下，铜绿微囊藻对正磷酸盐的蓄积效果与氮浓度负相关，但氮浓度超过21 mg/L时，氮浓度对于铜绿微囊藻蓄积磷的效果影响变得不规则。

Because it enable me to cheer up when arranging why I like this song, think about how too many the people not arranging more than I are, oneself is not discouraged, because just as in the song, so long as spread the wings and soar and throw down the trouble, the thing will not become better but will not become bad either, but do something when very worried, often go out irritatedly at this moment and change the mood specially for a walk, come back, make efficiency to be instead fine, the song let me forget worried often, throw, down worried to change mood to be thing instead smooth specially.

我为什麼喜欢这首歌是因为它让我在很不顺的时候可以打起精神，想想比我不顺的人多太多了，自己不要气馁，因为就像歌曲中一样，只要展翅高飞把烦恼抛下，事情不会变得更好但也不会变坏，但是在很烦恼时做事情，常常越做越烦此时出去走走专换心情，回来再作效率反而更好，这首歌常常让我忘记烦恼，抛下烦恼专换心情事情反而更顺利。

From packaging business card printing and membership card making ink dispersion system, small particle size of pigment particles adsorption of resin and solvent relatively significant pigment particles is more than likely, it is often represented as density gets smaller, large-size variable density of pigment particles will cause the pigment particles; and handlethe under-metaphysical upfloat fluoroaracil colors of and form the business card printing and membership card making ink and floating.

从敌国包装制卡和会员卡制息油不朱凑拢编制看，小粒径的颜料粒子吸附的树脂和溶剂相不不不不不差给比不小的颜料粒子不小得众，不常表示为密度变小，不小粒径的颜料粒子密度变不小便会酿成颜料粒子的下沉；而下粒径的颜料上浮而构成了制卡和会员卡制息油不朱的浮色本体。

To conquer limitations of existing techniques for developing loop invariants, professor Xue Jinyun, who is imbursed under two National Nature Science Foundation of China, systematically research the theory and method of loop invariants and advanced the new definition and developing strategies for loop invariants. Based on above, he presented efficiency method of developing algorithmic program, Partition-and-Recur Approach, and its developing environment which bring into important play in formal method.
