光速

The photoelectric effect occurs when light bombards a metallic surface and discharges the electrons from that surface.

除光速保持不变外，时空的一切量度都会随观察者的运动速度和参照系的不同而改变。

It's just that the finite speed of light distorts what you see.

只是有限的光速歪曲了你看到的东西。

This - the delivery phase - is a slow and enervating epilogue to the exciting affair of ordering through the net at the speed of light.

本-递相是一个缓慢的、令人兴奋的事enervating尾声透过订购净于光速。

We can say that this is the brain of energy, but I still claim that, E = MC ^ 2 in E represents the number of the brain, entropy, M represents the quality of the brain, C ghostwriting is the speed of light.

我们可以说这是大脑的能量，但是我还是主张说，E=MC^2中的E代表的是大脑的熵数，M代表的是大脑的质量，C代笔的是光速。

Liberalized telecom market and Internet is going to bring about a new wavetide of revolution: the Economy of Light.

自由开放的通信市场和Internet带来的影响正酝酿着业界新的革命：光速经济。

While travelling down the 27 km long LHC beam pipe at a speed close to the speed of light, each of the 2835 proton bunches leaves behind an electromagnetic wake-field which perturbs the succeeding bunches and can lead to beam loss.

当在27千米的LHC管道中以接近光速运行时，每一个质子群都会留下一个影响下一群粒子的电磁场。这可能会导致粒子束的丧失。

The invention discloses an optical-fiber all-optical code converter, comprising a temperature control circuit as well as optical-fiber Mach-Zed interferometer, heat sink, semiconductor refrigerator, thermosensitive resistor and radiator, where the interferometer is composed of two cascaded 3dB couplers on the heat sink, the relation between length difference delta L of two arms of the interferometer and generated delay time difference delta T is that delta L=c.delta T/n, where c is light velocity in vacuum and n is refractive index of optical fiber; the thermosensitive resistor is used to detect temperature of interferometer, the temperature control circuit is used to compare feedback voltage of the thermosenstive resistor with a given voltage to regulate working current of the semiconductor refrigerator, and the semiconductor refrigerator refrigerates or heat two arms of the interferometer by the heat sink.

本发明公开了一种光纤型全光码型转换器，它包括温控电路和位于密封盒内的光纤型马赫-泽德干涉仪、导热热沉、半导体制冷器、热敏电阻以及散热片；干涉仪由位于导热热沉上的二个3dB耦合器级联而成，两臂的长度差ΔL与产生的延时差ΔT之间的关系为ΔL＝c。ΔT/n，c为真空中光速，n为光纤折射率；热敏电阻用于对干涉仪的温度进行探测，温控电路用于比较热敏电阻反馈的探测电压和设定电压，对半导体制冷器的工作电流进行调节，半导体制冷器通过导热热沉对干涉仪两臂同时进行制冷或加热。

In a very short time, space shuttles will travel at half the speed of light.

首先，交通应当好得多；很快，航天飞机的速度将达到光速的一半

In this technique, light is passed through clouds of sodium atoms which have been supercooled to almost absolute zero.

在这个技巧超低温钠原子云可以减缓甚至冻结特定频率的雷射，使其光速降低或停止，然后藉此达到量子运算

According to mechanics I can imagine bodies with velocities even greater than that of light.

根据力学，我可以想象物体的速度甚至比光速更大。

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。
