The velocity of light in empty space always has its standard value, independent of the motion of the source or receiver of light.

光在空中的速度永远为标准值，它与光源及光的接受者的运动无关。

The number expressing the velocity of light appears explicitly in the Lorentz transformation, and plays the role of a limiting case, like the infinite velocity in classical mechanics.

表示光速的数明显地出现在洛伦兹转换中，并且如同经典力学中的无限大速度那样，光速将成为一个极限速度。

At the same time, because of the velocity of the matter particles are far slower than the velocity of light, the action time become longer, so the precision and the sensitivity of the matter wave interferometers can be increased.

与光学干涉仪相比，物质波干涉仪的一个重要特性是，可用于研究引力效应；同时，由于物质粒子的速度远低于光速，所研究过程的作用时间增长，因而它的灵敏度和精度可以极大地提高。

In the relativity theory it depends on both rest mass and velocity. The resistance becomes infinitely great as the velocity approaches that of light.

在相对论中它不仅与静止质量有关并且与速度也有关，当速度接近光速时，抗力便成为无限大。

In other words, its mass must increase without limit when its velocity approaches the velocity of light.

换句话说就是，当它的速度接近于光速时，它的质量肯定无限制的增大了。

The main factors effecting on exploration precision of surface wave are analyzed in the light of calculation of phase velocity of surface wave; the merits and demetits of common computing methods for phase velocity between stations and their applied range are discussed and calculation of interstation Green's function for correcting phase is put forward to get the precise phase difference between two stations.

分析了影响面波勘探精度的主要因素，针对计算面波相速度的精度问题，讨论了常用测量台间面波相速度方法的优缺点及其适用范围，并提出通过测量台间格林函数进行相位校正，以得到两台之间的精确相位。

分析了影响面波勘探精度的主要因素，针对计算面波相速度的精度问题，讨论了常用测量台间面波相速度方法的优缺点及其适用范围，并提出通过测量台间格林函数进行相位校正，以得到两台之间的精确相位。以合成的高频理论地震图作为记录信号，并在理论地震图上叠加了 2 0 %的随机噪声，利用这些方法分析理论信号，数字实验表明：在相干频率范围内，格林函数方法能够精确测量台间相速度，而互相关法和窄带通滤波互相关法所得结果较为离散。

Hot-humid climatic wind tunnel the paper introduced can simulate natural climate environmental elements namely solar radiation、air velocity、air temperature and humidity, according to the variant velocity of flow and regulation of infrared light, humidifier, heating and cooling facility.

热湿气候动态风洞实验台在具有可调低速风外，还通过设置红外灯、加热与制冷、加湿与除湿装置，初步实现了对室外自然气候要素太阳辐射、风速及温、湿度环境的模拟控制。

Since the velocity depends on the medium through which the light is passing, it will be different in glass from the velocity in empty space.

因为光的速度依光所通过的介质而异，因此光在玻璃中与在真空中的速度不相同。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
