查询词典 collinear

We have proved experimentally and theoretically that OBNC PM is more interesting than collinear PM in OPA and OPO due to its two characteristics: noncriticality for the noncritical beam and collinearity of the propagation directions of energy of the noncritical beam and pump beam in the crystal.

OBNC过程中作用光波中的一个光束与所产生谐波光束是非临界的，并且它们的能量流方向是一致的；OBNC具有很大的容限角，而其匹配条件比共线匹配过程宽容得多，从而可以使现有的多种非线性光学晶体通过OBNC获得比共线情况更有效的非线性作用。

This thesis makes use of complex numbers to study geometry. It mainly considers the following questions: using complex numbers to express collected points and curves on the level;geometric applications of complex numbers on collinear,concurrent,round,Mobius Mappings of Complex numbers problems,etc..Meanwhile,this thesis recommends some methods for thinking on mathematics.

本文利用复数来研究几何，主要考虑如下的问题：平面上的点集的复数表示；平面曲线的复数表示；复数在共线、共点、共圆、复数的麦比乌斯变换等几何问题上的应用，在说明这些应用的同时介绍一些数学上常用的思考方法。

That is,(1),Angle-tuning curve in thex-zplanefor a type II KTP OPG process phase—matched pumped by a1.064μm Nd:YAG beam and(2),Tuning curves for a 532nm pump(second harmonlcof Nd:YAG)for COllinear type II phase matching in thex-y,plane(θ=90°),they-zplaneand thex-zplaneIn addition,from the Sellmeierequations,the walk-off and group velocity dispersion effects were also calculated.

计算得出，(1)Nd：YAG1.064μm泵浦的KTP晶体在x-z调谐面内的II类相位匹配的角度调谐曲线；(2)Nd：YAG二次谐波532nm泵浦的KTP参量器件在x-y，y-z以及x-z调谐面内的II类共线相位匹配的角度调谐曲线。

The complexity decreases; the operational problems,such as collinear nodes,reflexions and signalinterferences,are reduced; and finally it avoids the overlapping problem.

这一个运算法则的效率以下列的有关结果为基础：复杂减少；操作的问题，像是在同一直线上的节点，弯曲和讯号干扰，被减少；而且最后它避免交叠处理问题。

I was particularly intrigued when a friend pointed out a much simpler collinear, consisting of just a length of copper wire appropriately bent, as detailed here, with a claimed gain of about 6dBi.

当一个朋友告诉我，有人把一段铜线弯曲成一个简单的天线，，就有 6dBi的增益，我的好奇心被激发起来了。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
