查询词典 refracted rays

RESULTS:After pinealectomized mice was irradiated WBI with 75 mGy X-rays,we found levels of plasma corticosterone increased obviously,and the effects of the proliferative reaction of splenocytes to ConA and spontaneous proliferation of thymocytes was found to be decrease. But injecting melatonin into pinealectomized mice or putting melatonin in the cultured cell,its immune functions might renew the enhancement.CONCLUSION:Melatonin of pineal gland might regulate the immunoenhancement induced by low dose radiation.MeSH Pineal body; Melatonin; Radiation; Corticosterone; Immunity,cellular

低剂量辐射(low dose radiation，LDR)全身照射(whole body irradiation，WBI)可引起免疫系统的兴奋效应，主要表现在以T淋巴细胞功能激活为主的细胞免疫和体液免疫功能的增强并可提高机体的抗瘤作用［4，5］，在LDR诱发免疫功能增强的同时伴有下丘脑-垂体-肾上腺皮质系统功能下调等神经内分泌功能的改变，神经内分泌对免疫系统的调节可能是LDR免疫兴奋效应发生的必要条件，松果腺MLT与辐射免疫兴奋效应的关系值得研究。

He was a pioneer in the use of X-rays.

他是最早使用X光的人。

Though they were young they walked with bowed heads, which gait of grief the sun's rays smiled on pitilessly.

虽然他们都是年轻人，但是他们走路的时候都把头低着，太阳微笑着把光芒洒在他们悲伤的步伐上，一点儿也不可怜他们。

The light source directs rays through a plane convex lens that focuses the light into a parallel beam. The light beam passes through the grid diaphragm, which splits it to produce a second beam of light 90° out of phase.

光源将光线照射到平凸透镜上，透镜将光线聚焦成平行光束，光束穿过光栅膜片，光栅将光束分离出第二根90度异相光束。

Here, the meaning of virtual focus is a "point" from which rays of light seem to emanate but do not actually do so such as in the image in a plane mirror.

这里所指的虚焦点是一个"点"，从其中的光芒似乎产生，但实际上没有这样做（例如在图像在一个平面镜）。

Platelike, as the hard toothlike scales of sharks, skates, and rays.

楣形的盘状，如鲨鱼、恶鱼和虹鱼的硬齿状的鳞

I Know I Shall Die in the Rays is the masterpiece among lyric poems written by Tsvetaeva, Russian poetess at Silver Age.

《我知道，我将死在霞光中》是俄罗斯白银时代女诗人茨维塔耶娃抒情诗中的一篇佳作。

Equatorial, or low, latitudes are hotter than the polar latitudes because of the angle at which the rays of sunlight arrive at the Earth's surface.

由於太阳光线到达地球表面的角度不同，赤道或较低纬度区比两极纬度区热。

This method is to lay the polarizing code of the different polarizing eyepiece angle in the different direction. Then, each direction's optical fiber was coupled into a bunch of optical fibers. After the focusing collimation set of lenses injection solution leaning path of rays, the laser incidence direction was obtained through the judgment circuit analysis.

该方法是通过在不同方向上放置不同起偏角的偏振片编码，再将各个方向的光纤耦合成一束，经准直透镜组射入解偏光路中，通过判断电路分析得到激光入射方向。

When you are positive in your mi ss ion inside, that positive rays will reflect not only on your face but also in what you do and you are going to overcome whatever difficult situation, however tough it may be...

当你内心充满积极思想时，这种积极的电波不仅会反射在你的脸上，而且会照射在你的行动上，你也将能够克服不管是多么艰难的困境。

Continuously improve the production mechanism, to provide customers with better quality products and services.

不断的完善生产机制，给客户提供更优质的产品及服务。

B:Yes, he was the very prize-winner in the court tennis ten years ago?

是的，他是十年前的世界网球冠军。
