The 4 nucleotides of DNA sequences can be further encoded with two - bit digits in which t he first bit is the base bit to encode purines and pyrimidines and the second bit is the functional group bit to encode the keto group and amino group. According to the degree of degeneracy of genetic codes and the two dimension distribution of molecular weights and isoelectricpoints of amino acids , a set of classification graph(Venn' s diagram) of amino acids can be obtained. It is suggested that the amino acids of high degenerate group are mostly small and simple, and constitute the transmembranic structure or the structural domains of protein molecules. So amino acids of high degenerate group might appear in the early evolution stage.

根据氨基酸遗传密码子的简并程度并以分子量及等电点作为氨基酸的化学特性坐标，作出其二维集合MP分类图，根据氨基酸的分类分析，可以认为：高简并度氨基酸多数是脂烃类和羟脂烃类的氨基酸，分子量比较小，分子结构比较简单，大部分为疏水性，主要组成跨膜结构或蛋白质的结构域，可能是出现较早的氨基酸；而低简并度的氨基酸，分子结构比较复杂，分子量比较大，多数是和蛋白质功能有密切联系的基团，可能是进化出现较晚的结构。

Magpie match good, iron teacher, you don't know of, the whet son is our young lady painting of diagram, best of the teacher all make uncertain it, recognize our young lady.

喜鹊配合得好，铁师傅，你不知道的，这个磨子是我们小姐画的图，最好的师傅都搞不定它，只认我们小姐。

The disappearance of the three characteristic absorption peaks corresponding to the acridinium salts and the newly formed peaks at 280 nm for 1 and 288 nm for 2 strongly suggested transformation of the acridinium moiety into the corresponding acridane via anionic addition to the C9 position of the former (Figure 2b).

与吖啶盐相应的三个特性吸收峰的消失以及新形成的峰值（1为280nm，2为288nm），强烈表明了吖啶盐分子部分通过阴离子加入到前者的C9位置而转化成了相应的吖啶（图2b）。

Except the castling, the move rules of the rook are the same as in Chinese chess. As Figure 2-6 shows, with horizontal and vertical moves, unlimited spaces. Capture rule: The rook can capture the opponent's chessmen when these chessmen are at the points reachable by the rook.

除了王车易位外，车的走法与中国象棋中车的走法相同，如图2-6所示横、直两种走法，每着格数不限，吃子方法：只要对方的棋子在车可走到的格子上，车就可以消灭对方的这个棋子。

Naturally, we can ask, in general, for the McKay quiver of G which is a finite subgroup of a generalized linear group, what its construction is and what relation there is with the conjugacy class of the group G.

我们自然会问：一般地，一般线性群的有限子群G的McKay箭图的构造如何以及它与群G的共轭类关系怎样？

These diagrams occur respectively for the conjugacy classes of these subgroups.

而这些拓广Dynkin图恰好一一对应于SL(2，C)的有限子群的共轭类。

The contents include the layout optimization models of the difform graph elements, the optimality conditions , the optimality functions, the optimization algorithms for the subproblems, the algorithms for the non-overlap constraints and the unproved genetic algorithm.

主要包括不同图元的布局优化模型、子问题的最优性条件、最优性函数和优化算法、判断不干涉性算法及改进的遗传算法。

He rushed across the plain like a winter torrent that has burst its barrier in full flood; no dykes, no walls of fruitful vineyards can embank it when it is swollen with rain from heaven, but in a moment it comes tearing onward, and lays many a field waste that many a strong man hand has reclaimed- even so were the dense phalanxes of the Trojans driven in rout by the son of Tydeus, and many though they were, they dared not abide his onslaught.

泛滥的河流，汹涌的水头冲垮了堤坝，坚固的河堤已挡不住水流的冲击，那一道道卫墙，防护着果实累累的葡萄园，亦已刹不住它的势头，宙斯的暴雨汇成滚滚的洪流，翻涌升腾，荡毁了一处处精耕细作的田园。就像这样，图丢斯之子打散了多支特洛伊人的队伍；敌方尽管人多，但却挡不住他的进攻。

U(4) algebra is very suitable to describe triatomic molecules, for their Fermi interaction can be described by using nondiagonal matrix elements of Majorana operator.

在研究多原子分子的李代数方法中，尤以U(4)代数适合描述三原子分子，这不仅仅是因为U(4)代数完全描述的是三维情形，物理图象更加清晰直观，而且，U(4)代数的Fermi相互作用可以由Majorana算子的非对角元素给出，不需要再引进另外一个代数。

Digital image process technique is used in pantographic faults monitoring, and a new algorithm named window-edge tracking is proposed in this paper. Based on the binary image of edges which is detected by Canny operator, a window in proper size is set to track the discontinuous edges to estimate the position of the lost edges. With this method continuous edges will be obtained, and continuous and smooth edges will be got after least-squares curve-fitting.

中文摘要：将数字图像处理技术应用于受电弓故障监测，提出一种新型的窗口边缘跟踪算法，在采用Canny算子计算出边缘二值图的基础上，设置适当大小的窗口对初始不连续边缘进行遍历，估计断点处边缘点位置获得连续边缘，并采用最小二乘法拟和出连续平滑的曲线函数。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
