光速

The earth moves at a crawl compared with the speed of light.

与光速相比，地球也只是在爬行。

The earth moves at a crawl compared with the sp d of light.

与光速相比，地球也只是在爬行。

How would you know the hyperdrive is deactivated?

你怎知道超光速被人破坏了？

We cannot dispense with the idea of the speed of light.

我们不能废弃光速这个概念。

"Einstein's mass-energy relation :Relationship between mass and energy in Albert Einstein's special theory of relativity , expressed E = mc2, where c equals (300,000 km/second), the speed of light."

"爱因斯坦质能关系在爱因斯坦狭义的相对论中用公式E＝mc2表示的质量和能量之间的关系。式中c为光速，即每秒300，000公里。"

The theoretical discovery of an electromagnetic wave spreading with the speed of light is one of the greatest achievements in the history of science.

从理论上发现以光速传播的电磁波，这是科学史上最伟大的成就之一。

Tuesday's experiment took place at a record total collision energy of 7 billion billion electron volt s and at a nano-fraction of a second slower than the speed of light in the 16.8 mile Large Hadron Collider.

周二的实验中，在长达16.8英里的大型电子对撞机里，两束质子流以创纪录的7万亿电子伏特的总能量进行超高能量对撞，对撞速度仅比光速慢了1纳秒。

In inertia system K,geometric sphere is changed to elliptic sphere in K system by Lorentz transformation ,and the pre-sphere of optical wave in K system is changed to sphere in K system.

对惯性系K中的几何球面施以洛仑兹变换，在K′系得到扁椭球面；对K中的光波前球面，在K′系则得到球面；两者皆源于时空的基本属性，但前者是由于物体长度的相对性，后者则是由于光速的不变。

No input of energy, however great, can push the speed past the speed of light.

不管供给多大的能量，也不可能使速率超过光速。

The gravitational field is so strong that the escape velocity near it exceeds the speed of light.

重力场是如此的强大以致於靠近它的逃逸速度超过光速。

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。
