In this paper the internal microdefects of single crystals of〔Ca_3(VO_4)_2〕were studied by Doppler broadening S parameter and positronlifetimes under different growth conditions and different physical treats.

本文用正电子湮没 Doppler 展宽 S 参数和寿命，研究了在不同生长条件下和经过不同物理条件处理的正钒酸钙〔Ca_3(VO_4)_2〕晶体内部的微观缺陷。

According to the boundary relations of the electromagnetic field, and based on the phenomena of double refraction and double reflection in crystals, the reflectivity and transmissivity are deduced at boundary when an extraordinary beam is incident from an isotropic medium upon a crystal or from a crystal to an isotropic medium with optical ax.

为分析非常偏振光在晶体表面的能量损耗，给出一种求解反射率和透射率的方法，即根据电磁场的边值关系以及晶体的双折射和双反射现象，求解晶体光轴在入射面内时，非常偏振光从各向同性介质入射到晶体和从晶体出射到各向同性介质两种情况的反射率和透射率的方法，并给出反射率和透射率的解析解，同时得到对于晶体光轴在入射面内的情况，光轴的取向对非常偏振光反射率的大小几乎没有影响，但对产生全反射的临界角θc影响较大的结论。

Although Dragoon was defeated, the difference between Dark and Light crystals remained.

虽然巨龙后来被击败了，但是黑暗与光明的水晶却遗留了下来。

This is because the top of the troposphere is normally very cold, causing ascending water vapour to freeze into ice crystals that drift and fall, rather than continuing up into the stratosphere.

这是因为对流层的顶端通常极其寒冷，上升的水蒸汽凝结成飘落而下的冰晶，而没有继续上升进入平流层。

"Druse:a crust of tiny crystals lining a rock cavity, usually composed of the same minerals that occur in the rock."

"晶簇：嵌于岩石洞穴的小晶簇，一般由与岩石相同的矿物成分组成。"

Druse crystals were produced in palisade cells under all light conditions but crystal diameter changed, being greatest at 100 E m^(-2) s^(-1) and decreasing with higher light.

在所有之测试的光强度下，栅状叶肉细胞内均会产生晶簇状的草酸钙晶体，但所形成晶体的直径并不相同，在100E m^(-2) s^(-1)光强度下其直径最大，而在光线较强时，晶体的直径则减小。

Now Morris and others have found the strongest evidence yet for magnetic monopoles, in small crystals about the size of an ear plug.

现在莫里斯和他的组员发现了迄今为止表明磁单极子存在的最有力的证据，这些证据存在于一个和耳塞大小差不多的晶体之中。

Metals on the absorption of laser light energy to the metal actually inside the transmission, once the incident laser photon to metal crystals, photon elastic collision with electrons, photons transfer their energy to the electronics, from the low-energy level of electronic transitions to the high-energy level.

金属对激光的吸收实际上也是光能向金属内的传输，一旦激光光子入射到金属晶体，光子就与电子发生弹性碰撞，光子将其能量传递给电子，使电子由原来的低能级跃迁到高能级。

By using calculated activation energy of the V colorcenter and measured current-time curves, mechanism explanation of the colorcenter formation for the electrolytically colored crystals is presented.

借助算得的V色心激活能和测得的电流~时间关系图，对经此种电注入着色晶体中色心形成提出机理解释。

It has been recently suggested that a simple model based on the concept of optical electronegativity and some other parameters should be good enough to study the main properties of ionic crystals and semiconductors with the use of only a few numerical constants.

它已 最近提出一个简单的模型的基础上，的概念，光电和其他一些参数应该不够好，研究的主要性能的离子晶体和半导体与使用只有极少数的数值常数。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
