查询词典 beams

It's very important to understand that this was unconnected with electromagnetics, hidden microphones, targeted beams, or anything else of that nature.

非常重要的一点是，这是与电磁、隐藏的传声器定向电波光束或其他类似性质的东西毫无关联的。

Engineers adopt the ultrasonic technique, matched with the electrometric method , to study damage and breaking features of two concrete notch beams which have different open depths.

利用超声波技术并辅以电测法对 2组不同开口深度混凝土缺口梁的损伤断裂特性进行了试验研究。

Examples are charged particle beams , an electron cloud in a Penning trap , and positron plasmas.

Because COTY colour picture tubes adopt XL lens as main lens, three electron beams are focused by a larger common lens in addition to three circle aperture lenses.

RCA公司在八十年代研制出COTY彩色显象管，它采用XL透镜做主聚焦透镜，其中除了三个单独的小透镜起聚焦作用外，三个电子束还受到一个公用大透镜的作用，因此透镜像差得以降低。

At the same time, the cooperation of the multi-layer frame structure is researched with FEA when the pre-stressed threads are stretching, and the relationship between the beam of stretching layer and the beams of nearly layers is discussed. The layout effect of regular reinforcement in the beam on the pre-stressed effective quantities is also analyzed, and the elementary estimation formula of pre-stressing loss on the multi-layer frame is also deduced according to the pre-stressing loss of one-layer pre-stressed frame structure.

同时文中还运用有限元对多层框架结构在预应力张拉过程中，某层梁预应力的张拉与相邻层梁的影响关系和结构各构件的整体协同工作做了研究，分析了非预应力筋在梁中的配置对框架梁预应力有效量的影响；并且在一层框架梁侧限预应力损失的基础上，扩展了多层框架结构中侧向约束引起梁的预应力损失值的初步设计估算公式。

However, the output beam quality of semiconductor laser is poor. Because of the waveguide properties of their active areas, semiconductor lasers generate large divergence-angle beams with elliptically shaped intensity profiles.

由于半导体激光器的结构特点，使得它发出的光束在垂直于结平面方向上远场发散角和平行于结平面方向的远场发散角相差较大(在垂直和平行于结平面方向上的发散角大小分别在30°左右和10°左右)。

In principle, it is feasible to detect energetic particle beams used in flash perspectivity directly by CCD.

从原理上看，利用CCD来直接探测用于闪光透视的高能粒子束是可行的。

" And Jove answered,"Juno, you need not be afraid that either god or man will see you, for I will enshroud both of us in such a dense golden cloud, that the very sun for all his bright piercing beams shall not see through it.

" 听罢这番话，汇聚乌云的宙斯答道："赫拉，不要怕，此事神和人都不会看见；我会布下一团金雾，稠匝浓密，罩住我俩，连赫利俄斯也休想看穿，虽然他的眼睛，那灼灼的目光，谁都无法企及。

The purpose of the device is to solve the problem that current angle tuning technique can not perfectly control the small angle of the two incoming optical beams of the single etalon.

本发明的目的是解决现有角度调谐技术对于单标准具的两束入射光的小夹角控制不好的问题。

It is found that due to the interference between the multi-reflected beams inside the etalon,the transmitting pulse is composed of a series of sub-pulses which are separated by the one-way traverse time of the light inside the etalon.

由于光在标准具内多次反射所引起的干涉效应，发现输出的光脉冲包含了一连串的次脉冲，这些次脉冲的时间间隔等于光单次通过标准具的时间。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
