查询词典 ultraviolet rays

But the sun's rays then reach us despite having passed, first, through an enormous thickness of the higIT strata of the air, the minute dust of which reflects maximum of the higIT strata of the air, the minute dust of which reflects maximum of the blue rays away from us, leaving the complementary yellow light to pass on, Then, the somewhat coarser dust reflects the green rays, leaving a abundance orange-coloured light to pass on; and finally some of the yellow is reflected, leaving almaximum pure red.

这就充分呈现了低空尘埃的数量之大。但是太阳的光线终于到达了地面。它们先是穿过厚度极大的高空大气层，其中的细微尘埃把大部份蓝色的光反射掉了，让补色的黄光继续通行。然后，粗粒尘埃又反射掉绿色的光，让偏橙色的光继续通行。最后，部份黄色的光也反射掉，剩下几乎是纯红色的了。

An analysis is made about Descartes rays of transparent round-section fibers——a special internal surface reflection rays of the fiber when parallel rays strike the fibers perpendicularly to fiber axis.

分析了透明圆形截面纤维在垂直纤维轴光线照射时纱维内表面反射光的一种特殊现象———笛卡尔线现象。

The specificity of the surface gained in this way is that when the beam of rays parallel to its axis of rotation falls on it, the beam is reflected so that all the rays meet in one point, known as the focus, in the same way that optical lenses focus light rays in their focus.

抛物线的表面或曰抛物面，是由抛物线围绕其对称轴旋转而成，其特点是，和抛物线对称轴平行的射线波束被抛物面所反射，所有的电波都在同一点汇聚， 1 September，2009 3D 角反射天线作馈源的 5.8GHz 偏馈抛物面天线我们把这点叫做焦点。

UV rays and gamma rays are other examples of cosmic rays that can originate from extraterrestrial objects like stars and supernovas.

其他宇宙射线的例子还有紫外线和伽马射线，他们源自于地球外的物体如太阳和超新星。

The Ultraviolet absorption wavelength, standard curve, recovery and accuracy were studied by Ultraviolet spectrophotometer and HPLC.

用紫外分光光度计和高效液相色谱仪，对其紫外吸收波长、标准曲线、回收率和精密度等进行研究。

To estimate the effects of enhanced ultraviolet radiation-B on upgrowth of maize and design answerer plans,the article studied influence of enhanced ultraviolet radiation-B on maize in middle-high elevation and arid regions.

探讨UV-B辐射增强对中高海拔干旱地区玉米的影响，可为正确评估UV-B增强对玉米生长发育的影响程度并据此制定合理的应对措施提供科学依据。

Ultraviolet sunlight can stimulate melanin in the skin, freckles and other skin diseases induced change, the impact of your face, so medical experts will be sunny beauty known as the skin Callisthenics enemy, that women in particular should be careful, even the coldest winter "Ultraviolet" still strong, so applying sunscreen when they go out the best.

阳光中的紫外线可刺激皮肤中的黑色素，诱发雀斑等皮肤病变，影响你的容貌，因此医学美容专家将阳光称为皮肤健美的敌人，强调女性尤其要当心，即使是寒冷的冬天里"紫外线"也依然强烈，所以外出时最好涂抹防晒霜。

The ultraviolet cathodoluminescence spectra of two crops of Chatham synthetic diamonds were analyzed by cathodoluminescence spectrometer made by ourselves and mounted on JCXA-733 EPMA. The research results show that the cathodoluminescence spectra of Chatham synthetic diamonds have ultraviolet peaks at 234 and 268 nm.

用自制的阴极发光分析仪在JCXA-733电子探针上分析两批美国Chatham公司合成钻石的微区紫外－可见阴极荧光，结果表明Chatham合成钻石具有峰波长为234， 268nm等的紫外阴极荧光谱。

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
