查询词典 P.Q.

That is, if ''Q'' is special orthogonal then one can always find an orthogonal matrix ''P'', a change of basis, that brings ''Q'' into block diagonal form

就是说，如果''Q''是狭义正交的，则你可以找到改变基的一个正交矩阵''P''，把''Q''带回到分块对角形式

Entailment can be interpreted as follows: under all circumstances, if P is true, then Q is true.

蕴涵可表述为：在所有情况下 P为真 Q也为真时，那么 P 蕴涵 Q。

Then one solution would be for Shell to build at P,Esso to build as Q,B.P.as S,and Gulf at T,leaving either Shell or Gulf to build at R;however,if Gulf decides to back out of the whole agreement,then it is clearly impossible for the other three companies to erect the garages in the specified manner.

那么一种解决方法是Shell在P处修建，Esso建在Q处，B.P建在S处，Gulf建在T处，留下一个由Shell或Gulf建在R处；然而如果Gulf退出这一协议(在R和T建汽车修理厂)，则很显然，对其他三家公司来说，无论如何也不可能按照所约定的方式修建汽车修理厂。

Let P be a Markov operator in, and Q any ergodic Markov operator possessing finite invariant measure. In this note a simple and direct proof of the equivalence of the mixing property for Q and the ergodicity for Cardesian product PQ is given.

Conversely, a point P to the right of the origin, whose distance from the origin is d units, shall have as its corresponding real number the positive real number d and, similarly, if Q is a point d units to the left of the origin , then Q shall have as its corresponding real number the negative real number –d.

Conversely，在起源右边的点P，从起源的距离是d单位，将有作为它对应的实数正面实数d和，同样地，如果Q是点d单位在起源左边，然后Q将有作为它对应的实数消极实数–d。

In chapter 6, we study the dimension of a code associated with a difference set and we also study how to construct Ramanujan graph by using difference sets, we obtain:(1) let q≡1 (mod 4) be a prime power, p be a prime such that p｜〓, then the p-rank of the quadratic residue partial difference set in the finite field GF is 〓.

在第六章中，我们研究差集对应的码的维数及用差集构造Ramanuian图，得到了：（1）设q≡1（mod 4）是素数幂，素数p｜〓，则GF中的二次剩余部分差集的p-秩是〓。

In chapter 4, by AREELS, the Generalized Oscillator Strength Density Spectra were measured in the energy region from 56 to 66eV, with the incident energy 2. 5 keV and energy resolution 80 meV, at scattering angles from 0°to 6°, corresponding to the momentum transfer K〓=0.03~2. 01 a. u. The Fano profile parameters f〓 and q for the optically allowed transition 〓(0, 1)〓P°and the optically forbidden transitions 〓(1, 0)〓S〓and 〓(1, 0)〓D〓 were obtained as a function of K〓. With the hyperspherical coordinate wavefunctions, the dynamical correlation are discussed qualitatively. So, a new experimental way to study dynamical electron correlation effect is opened.In chapter 5, the widely used R-matrix theory was introduced. Then, the GOSDS for the optically allowed excitation series (1s〓)〓S〓→〓(0, 1)〓P°(n=2-4) were calculated by this method, and the Fano profile parameters f〓 and q were obtained sequently. So the electron correlation effect can be described by these parameters quantitatively, and the theoretical results were compared with our AREELS experimental results.

在第四章中，实验上，同样使用角分辨的高能量分辨快电子能量损失谱仪，在2.5keV电子入射能量和80meV的能量分辨下，测量了0°到6°散射角下的He原子双电子激发态在56~66eV的广义振子强度密度谱，这种情况，0°~6°对应的动量转移范围K〓=0.03~2.01a.u。，得到了光学允许跃迁的双电子激发态〓（0，1）〓P〓和光学禁戒跃迁的双电子激发态〓（1，0）〓S〓、〓（1，0）〓D〓的Fano线形参数f〓，q等随动量转移变化的曲线；观测到了几个强度很弱、能级很窄的光学允许和禁戒跃迁双电子激发态，用前人准确的理论结果进行了标识；通过比较弱共振〓（1，0）〓S〓和〓（-1，0）〓S〓的强度随动量转移K〓的变化规律，结合超球坐标理论计算的波函数，定性地阐述了在电子碰撞散射过程中它们各自不同的动力学电子关联效应，发展了一套在实验上研究电子关联效应的新方法。

The split between the two groups can hardly be papered over.
