Through the Radon transformation of the normally ordered Wigner operator we introduce two mutually conjugate intermediate coordinate- momentum representations. Based on them we construct the appropriate quantum phase space theory which includes the new Wigner operator adapting to this space and construct the appropriate generalized Fredholm operator equation and then find its solution. We then deriving the Hermite polynomials operator identities by applying the Fredholm equation. We also reveal the connection between the generalized Wigner operator and the 2-dimension normal distribution in statistics, which is useful to study the quantum tomogram. As the application of the entanglement Husimi operator theory we calculate the Wigner function and the Husimi function of the one- and two-mode combination squeezed state , study their characters through drawing the three-dimensional graphics.

由正规序Wigner算符的拉登变换引入了两个互为共轭的中介坐标-动量表象，在此基础上我们建立了相应的量子相空间理论，其中包括引入适合该空间的新的Wigner算符；并在该表象的基础上，建立了广义Fredholm算符方程，求出了它的解，并运用该方程导出有关厄米多项式的算符公式；揭示广义Wigner算符与统计学中的随机变量的二维正态分布形式上的相似，这对于研究量子态的tomogram(是英文Tomography的派生词)有用。

Mauricio Funes, the candidate for the left-wing opposition Frente Farabundo Martí para la Liberación Nacional, declared victory in El Salvador's closely-contested presidential election shortly after polls closed on March 15th.

紧接着3月15日投票结束后，毛里西奥·福奈斯，左翼反对派法拉本多·马蒂民族解放阵线候选人，宣布在势均力敌的总统竞选中胜出。

The paper analyses two kinds of new formulas on the equivalent friction coefficient of V-belt drive in the present mechanical design and finds out that one is reasonable but has certain error and the other is wrong.

对现行机械设计中关于V带传动当量摩擦系数的2种计算公式进行分析。认为其中一种公式是合理的，但存在一定的误差；而另一种公式却是错误的。通过推导V带欧拉公式，给出了计算V带传动当量摩擦系数的准确公式，并在公式中引入了一个新的参数——摩擦力方向角。在考虑皮带拉力变化既有径向滑动又有周向滑动的前提下，改进后的计算公式比现有公式更加完善

WHEN she landed in Mumbai on July 17th as the first front-rank visitor from Barack Obama's administration, Hillary Clinton, America's secretary of state, faced an unfamiliar difficulty.

当巴拉克？奥巴马政府内最有份量的出访者、美国国务卿希拉里？克林顿7月17日到达孟买时，她面临着未曾遇到过的困难。

As soon as Nikolay came in in his full-dress uniform of an officer of hussars, diffusing a fragrance of scent and wine about him, and said himself and heard several times said to him, the words,"Better late than never," people clustered round him. All eyes were turned on him, and he felt at once that he had stepped into a position that just suited him in a provincial town—a position always agreeable, but now after his long privation of such gratifications, intoxicatingly delightful—that of a universal favourite.

身着骠骑兵制服，周身散发出香水和酒的气味的尼古拉，一走进来便说了一句，并且也听到别人对他说了几遍"vautmieusxtardquejamais"，之后便被包围起来；所有的目光都朝向他，使他立即感受到他已进入他在那一省的适当地位——那向来愉快的，如今又在经过长期困苦生活之后陶醉于满足之中的，众人宠爱的地位。

The variational problems of the complete functional in calculus of variations are studied deperding on the arbitrary arguments,arbitrary multivariable functions and arbitrary-order partial derivatives of multivariable functions.

In chapter 4, sufficient conditions of at least one, two and multiple positive periodic solutions to a scalar functional differential equation with muti-finite delays are obtained by using a fixed point theorem introduced in [27] and [85] which is different from the one of a cone compression and expansion of norm type. It generalizes and improves some related results in the literature.

第四章利用文献[27]和[85]中所给出的不同于范数型锥压缩和拉伸的不动(来源：bc1cbcABC论文网www.abclunwen.com)点定理得到了具有有限时滞纯量泛函微分方程至少存在一个、两个和多个正周期解的充分条件，推广并改进了已有的相关结果。

Lividans. Using pIJ903 bearing tsr gene as a vector, the two furthermost fragments of the cluster, 4. 0kb and 1. 5kb in size respectively, were inserted into it. To facilitate the detection of gene replacement, apr gene was placed in the middle of the two inserts. OriT from E coli plasmid RK2 was also incoporated into the vector, therefore, pIJ903 derivatives can be mobilized from E.

在具有硫链丝菌素抗性基因的pIJ903的单—BamHI位点，同向插入了FR-008生物合成基因簇两个最远端的4.0kb和1.5kb片段，并在二者之间插入了可在链霉菌FR-008和变铅青链霉菌中表达的阿泊拉霉素抗性基因，同时也插入了有助于将质粒引入链霉菌的oriT片段，从而构建出了置换整个基因簇的基因置换质粒pHZ691。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
