波阵面

The process can be visualized as a wavefront being reflected back and forth between the two ends of the laser, picking up more photons with each reflection.

这过程可以想象波阵面在两个激光终端来回反射，伴随每一次反射集聚更多的光子。

Deformable mirrors hidden away above the silver covers on the ceiling are used to shape the beam's wavefront and compensate for any flaws before it enters the switchyard.

可变形的镜子隐藏在天花板上覆盖的银膜下面，这种镜子是被用来塑造光束的波阵面，并弥补它在进入调试间前出现的任何缺陷。

A train of light wave may often be represented more simply by means of rays than by wave fronts.

一列光波往往可以更简单地用光线，而不用波阵面表示。

Objective: To study the higher order aberrations of emmetropic and ametropic eyes with wavefront aberrometer.

To overcome the shortcomings of the traditional active decoying theory confronting an ARM(Anti-Radiation Missile),the monopulse angle is utilized tracking principles to deduce in the Cartesian coordinate system the bias angle formulas due to multiple sources.

针对反辐射导弹传统有源诱偏理论的不足，从单脉冲雷达跟踪合成波阵面法线方向的理论出发，对多个辐射源的诱偏公式在三维空间中作了推导，对多目标影响建立了较通用的干扰模型并分析得到该模型具有当只有一个干扰源时，诱偏方位角偏差跟目标干扰源方位角之差有关的特点，同时诱偏仰角偏差也有类似的特点。

可见，HD401井原油，是先期注入的少量下奥陶统-寒武系烃源岩生成的产物，在O〓烃源岩主体原油自北向南的充注过程中，&波阵面&式的推进结果使其处于该油藏的最南端。

As for the importance of the distribution of the solutions on the Pareto front, the following measures are introduced in the dissertation: the Niching technique for keeping the genetic diversity and the real coding combining with the average crossover operator for eliminating the so-called"ending effect"of the GAs coding.

求解Pareto波阵面时，解的分布性至关重要，本文从两个角度来提高解的分布性：一是采用小生境技术解决了基因材料多样性损失问题；二是采用常规实数编码配合平均交叉算子解决了端点效应问题。

After basic theory and definings of Voronoi diagram and also parameterized bisectors have been analyzed,two main algorithms of simple-connected at present have been compared;adjust the algorithm of initialization and data construct so as to obtain the algorithm could used in practice; extand the idea of wavefront-propagation algorithm to computing multi-connected voronoi diagram.

通过对Voronoi图的基本理论、定义和参数化平分线公式的分析，以及对两种主要单连通域Voronoi图算法的比较，作者改进了初始化算法和数据结构，得到便于工程应用的单连通域Voronoi算法，并将波阵面传播的思想扩展应用到多连通域的Voronoi图计算，形成新的多连通域问题算法。

It is also convenient to think of light as propagating as wavefronts .

同样可以简单地理解光以波阵面来传播。

Light may be considered as energy being transported in a train of wavefronts.

光可以看作是以连续波阵面传递能量。
