引入的

Then,a new result of quantum mechanics is given:considering an arbitrary manipulation of one EPR particle,which can be modeled in fullgenerality as a unitary interaction of that particle with an outside system or ancilla,ini-tially in a pure state,we shall show that such interactions can be used to prepare all andonly those states of the joint system(two particles in arbitrary entanglement and theancilla)that yield unperturbed marginal statistics for all measurements on the anotherparticle,with which the ancilla did not interact.

首先，我们介绍了量子通讯的概念是如何被引入的；其次，我们给出了一个新的量子力学结果：制备一对EPR粒子，然后把它们分开，如果我们对其中的一个粒子进行操作，那么该操作将不会改变另外一个粒子的单独测量的期望值。

An optimum threshold level is found that minimizes distortion of the power spectrum for speckle data of the circular and ring apertures.

The other is called Householder transformation method, in which the matrix of inconsistent equation group is orthogonalized and triangulated using Householder transformation, and then the Zernike coefficients can be worked out by using a backsubstitution technique. It is proposed for the first time. Being a method that can avoid the computational error effectively and can be easily performed, it has proven to be a feasible and efficacious algorithm.

特别是第二种方法由本文第一次提出，它避免了构造法方程组，从而避免了以前的方法因构造的法方程组出现严重病态而引入的计算误差，并且易於编程，因而是一种比较理想的实现Zernike多项式拟合的算法。

To show the security of this scheme, we present an explicit relation between the information that an eavesdropper can elicit and the corresponding error rate he/she would introduce.

Tis not a change from the present state, which perhaps corruption or decay has introduced, that makes an inroad upon the government, but the tendency of it to injure or oppress the people, and to set up one part or party, with a distinction from, and an unequal subjection of the rest.

现存国家所发生的变化，消蚀政府的，不是那些有可能引入的堕落和腐烂，而是政府趋向于伤害和压迫它的臣民，并扶植一部分人或一撮人，使它们区别并与其余的人不再平等。

However, please be noted that high sensitivity will allow the interfusion with exterior noise irrelevant to the quantity to be measured, which will be also amplified by the system. As a result, the accuracy of measurement is affected. So, the senor itself should have high signal to noise ratio, to reduce the exterior interfering signals as much as possible.

但要注意的是，传感器的灵敏度高，与被测量无关的外界噪声也容易混入，也会被放大系统放大，影响测量精度，因此要求传感器本身具有很高的信躁比，尽量减少从外界引入的厂忧信号。

In this paper, the influence of error propagation on soft demodulation in coded MIMO system is analyzed in detail. Besides, based on the thought of soft symbol interference cancellation, Iterative Channel Soft Information for coded MIMO system is further deduced and proved to have the same form as the inverse of row norm of Moore-Penrose inverse of channel matrix.

摘要该文针对编码MIMO系统，分析了MIMO检测过程中串行干扰删除引入的误差传播对软解调的影响，同时，借鉴软符号干扰消除的思想，推导出该系统中迭代信道软信息(Iterative Channel Soft Information， ICSI)的计算方法，并证明了该信道软信息等价于信道矩阵广义逆的行范数的倒数。

This paper presents an efficient approach of designing a special dome and its aberration corrector, using the method of Wassermann-Wolf differential equations to generate the optimum contour of the corrector through a macro in CODE V.

The bias drift caused by optical Kerr effect is indistinguishable from the rotational-induced Sagnac frequency shift.

光克尔效应引入的系统零漂与系统的真实旋转在测量时是无法区分的，因此成为主要的噪声之一。
