波阵面

The operative method was wavefront aberration-guded Lasik with Allegretto wave- light and Mona-2 keratome.

手术方法为波阵面差引导下鹰式准分子激光角膜原位磨镶术，采用WAVE-LIGHT公司的波阵面差仪和ALLEGRETTO鹰式准分子激光机，法国MORIA-2自动角膜板层刀。

Two coherent laser beams derived from a single source intersect at a fixed angle. The intersection volume of the two beams is positioned on the sample surface.

多普勒激光引伸计工作原理来自同一激光源的两个相同的激光束以固定的角度交叉，两个光束的交叉部分定位在试样表面，两个激光束的波阵面影响交叉部分的大小，并形成一个干涉图。

Two coherent laser beams derived from a single source intersect at a fixed angle. The intersection volume of the two beams is positioned on the sample surface. The wavefronts of the two beams interfere in the intersection volume and form an interference pattern.

来自同一激光源的两个相同的激光束以固定的角度交叉，两个光束的交叉部分定位在试样表面，两个激光束的波阵面影响交叉部分的大小，并形成一个干涉图。

The direction of propagation is in a direction perpendicular to the wavefront.

传播方向(除了各向异性的媒介物以外)是与波阵面垂直的方向。

He also obtained a proof of the refraction law in terms of the existence of wavefronts, a construction now called Huygens's principle.

他也获得依据波阵面存在的折射规律证据，现在称之为 Huygens 解释。

It keeps the same when the hypocenter location deviates from the center of the slab.

发现当俯冲板块中存在6%的低速异常时，直达P波和直达S波之间存在波阵面近平面的易于识别的P-S转换震相，其传播方向不因震源位置偏离低速层的中心而改变。

The point at which the incident wave, reflected wave, and mach fronts meet is called the "triple point"

入射冲击波、反射冲击波与马赫波波阵面汇合之点叫做"三相点。"

May be a reflection, refraction, diffraction, or any other type of wavefront.

可能是反射波，折射波，绕射波，或其它类型的波阵面。

Methods: Forty of cases 77 emmetropic and ametropic eyes were measured with an aberrometer based on Tscherning's principle with the pupils dilated. The Zernike coefficients and root mean square values of wavefront aberrations up to the 6th order were recorded and statistically analyzed.

40人77只正视眼及屈光不正眼，散瞳后用基于Tscherning原理的波阵面像差仪进行测量，记录高达6阶的波阵面像差Zernike系数和均方根值，并进行统计学分析。

Plane wave: Having wavefronts which are planar, as might originate from a very remote source.

平面波：波阵面是平面的波，如震源很远的波。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
