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。

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

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.

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.

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.
