In this study, on the basis of information theory and statistical methods, we use mutual information, n-tuple entropy and conditional entropy, combining with biological characteristics, to analyze the long range correlation and short range correlation in human Y chromosome palindromes.

本文中，我们利用信息论和统计学的方法并结合生物学的特征研究人类Y染色体回文序列的互信息、'n字'熵、条件熵，定量分析了回文序列的长程关联和短程关联，发现其中既存在长程关联，也存在短程关联，并且它们主要是由序列中的重复序列引起的。

In order to cipher out sum of square and effect estimation of combining ability, transpose procedure, merge sentence and z=x + y, gi= 1/(p+2 *(hi-2*zh/p), sij = xij -/(p+2)+ 2*zh/(p+1 *(p + 2) etc. transformations are applied in this study .New data gather and varieties are produced from original data to meet the analysis by using the sentences of keep, file, infile, put,set and so on.Multiple comparison of combining ability effect is carried outin SAS system by using fuctions of probf (f,dfl,df2), probt, tinv and lag , transformations of LSD0.o5=ee*abstinv(px,dfe, LSD0.01=ee*abstinv(pj ,dfe , and conditional sentence of if, then.

主要须用到transpose过程，merge语句以及统计代换z=x+y、gi=1／(p+2*(hi—2*zh／p)和sij=xij-／(p+2)+2*zh／(p+1*(p+2)等算出各种配合力平方和及其效应估计；用语句keep、file、infile、put、set等通过原始数据资料产生各种新的数据集和变量以满足分析需要；利用概率函数probf(f，df1，df2)和probt，反概率函数tinv，延迟函数lag，LSD_(0.05)=ee*abstinv(px，dfe、LSD_(0.01)=ee*abstinv(Pj，dfe等几个统计代换，以及if、then条件语句等实现了配合力显著性测验和配合力效应之差的显著性测验。

Combined CD method and a new conjugate gradient method given by Liu.Y, Storey. C, the second class of nonlinear conjugate gradient method is proposed, which not only has descent property, but also is proved global convergence with the general Wolfe line search. Finally, the numerical results show this class of conjugate gradient methods is very efficient.

第二类算法是结合CD法和Liu.Y， Storey.C提出的新共轭梯度法，提出一类新的非线性共轭梯度法，新方法不但具有下降性质，而且在推广的Wolfe线搜索下是全局收敛的，最后进行了数值验证。

In the second exception, the word initial'y' sound is actually a glide phonetically,which has consonantal properties;consequently,it is treated as a consonant,requiring 'a'.

因为'h'没有任何发音，不见声音。在第一个例外中，跟随冠词的是圆音，所以使用'an'。在第二个例外中第一个'y'实际上是

The fibrewise separation condition holds important status in the TOP_b categorythe objects are the fibrewise topological spaces over B,for two objects (X,p and,a morphism from X to Y is a continuous map such that p=q o Φ..

中文摘要：纤维分离条件在TOP_B范畴对象是以B为基的纤维拓扑空间，对于对象(X，p，，它们之间的态射是连续映射Φ：X→Y，满足p=q οΦ。

Use the camera system X、Y and micro-angle to contraposition, BGA solder ball overlap with the PCB board plate

利用摄像对位系统X、Y微及角度微调进行对位，使BGA锡球与PCB板焊盘重叠

The reactor is operating at 85% power with control rod X-Y inserted 20%.

一反应器在85%功运转，X-Y位置的控制棒插入20％。

The longitudinal coordinate -axis Y is the sum of "method points".

纵坐标Y轴是"方法点"的集合。

In this coordinate space the X axis points right, Y points up and Z points away from camera.

在这个坐标系中，x轴指向右边，y轴指向上边，z轴指向相机前方。

For example, if the screen resolution is 640*480, the right-lower corner of the screen is x==639 and y==479. If you want to convert the screen coordinate to window coordinate, use ScreenToClient function.

例如，如果屏幕分辨率是640*480，屏幕右下角的坐标是 x=639 y=479，如果你想屏幕坐标为窗口坐标，用 ScreenToClient 函数。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
