光速

Such a hypothetical particle (a tachyon, as opposed to the more familiar tardyon, or slower-than-light particle) might emit Cerenkov radiation analogous to the bow wave of a ship, and thus might perhaps be detected.

这样一个假设的粒子（超光速粒子是相对于较熟悉的次光速粒子，或者是亚光速粒子而言的）可能放出类似于轮船涡流的契伦科夫辐射，因此可能被探测到。

This paper made the discussion and illation in order to study the influence of light speed on the precision of CRDS in measurement of the absorption coefficient. A numerical calculation has been done according to the data provided by the experiments and part of scientific literature.

为了考察吸收系数的测量精度受光速变化的影响程度，进行了相关的分析和推导，并根据实验及部分文献提供的数据进行了数值计算，得到了忽略光速变化将导致测量结果偏小的结论，偏差值与腔镜反射率有关。

Pointing out that the singularity revealed the defects of the general relativity in theory and was not the intrinsic property in the nature world.

而通常所说的光速不变原理，指的是在惯性坐标系或局域惯性坐标系中，真空中的光速各向同性

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。

The subliminal light propagation is a consequence of the lossless normal dispersion.

这里的光速减慢和超光速现象是无吸收介质中的正常色散导致的。

And also, we have done some researches on the Fresnel number of polygon slits, high efficient retroreflective film, the superluminal and/or subluminal velocities of beams in vacuum, the zero-field truncation technology, fractional Fourier transforms and so on.

同时，开展了多边形光阑菲涅耳数、高效逆向反光膜、真空中光束的超光速与亚光速现象、零场截取技术、分数付里叶变换等相关领域作了研究。

If tachyons were shown to exist we might have to rethink the idea of causality, since they would appear in some circumstances to go backwards in time, so that to a hypothetical observer the emission of a tachyon would appear to be its absorption.

假如超光速粒子真的被证明是存在的，我们需要重新构想一下因果关系的概念，因为它们在某些情况下会在时间中逆行，所以对一名假想的观察者来说，超光速粒子的辐射将以吸收出现。

However, a negative-energy tachyon propagating backward in time could be reinterpreted as a positive-energy tachyon propagating forward in time; some physicists think that such a reinterpretation would be the loophole through which the principle of causality might be preserved. J. Richard Gott proposed in 1973 that, after the Big Bang, a tripartite Universe may have been formed, consisting of universes of matter, ANTIMATTER and tachyons.

然而，带有负能量的超光速粒子回到过去可以重新解释为，带有正能量的超光速粒子可以传送到将来；一些物理学家认为通过这样一个重新解释可以避开因果关系法则。J·理查德·高特在1973年提出，大爆炸之后，可能形成了一个三重宇宙，分别包括物质世界，反物质世界和超光速粒子构成的世界。

It's a prototype tachyon accelerator, built to generate faster-than-light particles.

这是一个超光速粒子加速器的原型机，用来制造超光速粒子。

A jet plane may reach a speed of around 3500 km/h but light travels at the speed of 1,071,360,000 km/h (a speed that you and I could not possibly comprehend), so you can imagine the difference in time that would be recorded if the clock were traveling near to that speed.

喷气式飞机能达到3500 km/h，但光速是1，071，360，000 km/h（一个你和我是无法想象的速度），那你想一想，如果那个钟能靠近光速的话，那个时差会有多大。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
