光束

Each beam starts out about as strong as the one in your laser pointer, but all together they end up pumping out 500 terawatts in two billionths of a second — roughly 500 times the entire peak power output of the United States.

每束光束刚产生时，强度仅跟你的激光指示器发出的激光强度一样，但是它们在二十亿分之一秒内，强度就能曾大到500太拉瓦，大约是美国能量输出峰值时功率的500倍。

The artificial daylight spread by the capital's orbital mirrors is sliced by intersecting flames of ion drives and punctuated by star burst explosions; contrails of debris raining into the atmosphere become tangled ribbons of cloud.

这个由首都星球的轨道镜面散发出来的人造白昼被交织的离子光束和爆炸火球切割得支离破碎；无数碎片雨点一般落到星球的大气层中，划出的轨迹化为云层中杂乱交错的缎带。

If corpuscles fall on the surface of glass, for example, it may be that a force is exerted on them by the particles of the matter, a force which strangely enough acts only in the immediate neighbourhood of matter.

如果作用在光的微粒上的力是垂直于玻璃表面的引力，那么光束新的运动路线将会在原来的路线与垂直线之间。

The formulas of the statistical average radius of wave-front circle edge dislocations had been developed for the coaxes beams that had different beam diamantes and crossbeams in the cases that the averaging time was shorter t

Theoretical analysis of the group delay dispersion caused by multi beam interference between two parallel optical surfaces was presented.The expression of Fabry-Perot etalons dispersion was derived.

推导了光通信系统中任意两平行光学表面间由多光束干涉引起的群延迟色散的表达式；分析了GDD的变化规律，包括周期性、平方律特性和对表面反射率的依赖关系。

The light beam then hits a film or photographic paper in proportion to the strength of the current.

光束然后点击电影或相纸的比例强度的电流。

"Flashtube, also flash tube:a gas discharge tube used in an electronic flash to produce a brief, intense flash of light."

闪光管：一种用于在电子闪光时产生短暂而强烈的光束的气体释放管。

" Flash tube, also flash tube:a gas discharge tube used in an electronic flash to produce a brief, intense flash of light."

The fractional Fourier transform of partially coherent flat-topped beams is also studied.

同时，我们也研究了部分相干平顶光束的分数傅立叶变换。

Generally,the energy density distribution of a TEA CO2 laser was flat-topped.

TEA CO2激光器输出光束的能量密度分布一般为平顶型分布。

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。
