In this article, the effect on the surface topography of the same material was analyzed by different processing methods, the value of surface parameter arithmetic mean R, root-mean-square roughness R and gradient root-mean-square value Z were used to appreciate the surface topography, and the data were processed with the software Matlab.

分析不同加工方法对同一种材料表面形貌的影响，采用表面形貌统计参数中的轮廓高度算术平均值R、轮廓高度均方根值R、坡度均方根值Z，对表面形貌进行评价，结果表明，准分子激光加工表面的R、R，和Z，值均比研磨加工表面小。

The difference between codon choice randomization in the region of protein regular secondary structure and that in coil region is investigated in detail. We find that the folding free energy of mRNA segments in different protein secondary structures is significantly different. The average Z score is -1. 38 and -1. 71 for regular secondary structure, but -0.93 and -1. 03 for coil.

我们仔细分析了在蛋白质规则结构区域（alpha螺旋和beta折叠）和无规则结构区域密码子随机选择的差异，发现处于不同蛋白质二级结构的mRNA片段的折叠自由能有显著的不同，对于规则结构，Human和E.coli的平均Z-score值分别为-1.71和-1.38，但是无规则结构的Z-score值分别为-1.03和-0.93。

这个符号也起到了指向作用，链接字母a到z，意思是亚马逊的商品无所不包。

NO.1 chromosome was submetacentric,NO.2 and Z chromosome were metacentric,and the others were telocentric,which was slightly different from the results of others. Additionally,analysis of G-banding patterns for macrochromosomes indicated that they were divided into 27 zones and 134 bands.

染色体形态分别为：NO.1染色体为sm型，NO.2、Z染色体为m型，其余染色体均为t型，这与前人研究结果存在一定差异。G带分析结果显示，鹌鹑的前9对大染色体及Z、W染色体G带可分为27个区，134带。
