Since cross ratio is an invariant of the group of all Mbius transformations,and a Mbius transformation maps a circle into another circle, it is convenient to represent a segment of circular arc with a parametric complex rational function.

利用Mbius变换的保交比性质和保圆性质，给出了一种快速、简便地生成平面上的一段精确圆弧曲线的新方法。

利用分块成向量的方法证明了MnMn(F为域F上所有n×n矩阵构成的乘法半群上的n×n拟正交矩阵组至多含有n个矩阵，利用方程组的解的理论证明了Mn中与给定矩阵A构成两两拟正交矩阵组的矩阵个数不超过n-Rank+1，从而得到Mn上保持拟正交性的线性映射φ要么是降秩的或者保秩的映射，要么φ的值域中含有幂零元。

After undertaking to the interact of dwell pressure, dwell time and mould temperature orthogonal experiment makes an on-the-spot investigation, reach: Material of miscellaneous 赑 OM(N2720 M63) and material of UHM WPE(GUR EP4221), the interact that basically is dwell time and mould temperature affects the systole of gear to be out of shape, to PA66(RTP 0205) material the systole that basically is gear of dwell pressure and influence of dwell time interact is out of shape.

对保压压力、保压时间和模具温度的交互功能进行正交实验考察后得出：对于POM(N2720 M63)材料和UHM WPE(GUR EP4221)材料，主要是保压时间和模具温度的交互功能影响齿轮的收缩变形，对于PA66(RTP 0205)材料主要是保压压力和保压时间交互功能影响齿轮的收缩变形。

As Spurgeon puts it, it is as if he says, I know the person into whose hand I have committed my present condition, and my eternal destiny. I know who he is, and I therefore, without any hesitation, leave myself in his hands.

司布真解释它时，仿佛保罗是说：「我把自己现今状况和永恒的命运交托在某人手上，我认识他，我知道他是谁，所以我毫不迟疑地把自己交在他的手上。

The specific properties of materials, such as the palate adhesion, dynamic cruor, anti-bacterial and the degradability of lysozyme, were studied, which provide valuable data for further application. The main creative ideas are listed as follows:(1) The water-retention chitosan/poly vinyl alcohol blend fiber was obtained by coagulating in 10％ NaOH/ethanol solution, and the blend and crosslink due to GA can enhance the mechanical properties of fiber;(2) The controlled degradable chitosan/gelatin blend fiber was obtained by solution filature, and the mechanical properties were improved;(3) The N-acylchitosan with the different degree of substitution were successfully prepared, and the relationship between structure and properties was estabilished;(4) By a new solvent system of 6％ NaOH/4％ urea for cellulose, the blood anti-coagulant function films were prepared by blending cellulose with chitin;(5) In the same solvent system above mentioned, the anti-bacterial blend films based on cellulose and carboxymethyl-chitosan were prepared, and the relationship of DS and the anti-bacterial property was concluded;(6) The controlled degradable chitosan films was obtained by the chemical crosslink.
