真空

In 1896, the French physicist Becquerel Republic issued a report on the work of a detailed description of the many experiments he found that uranium, uranium and its compounds have a special ability, it can automatically and continuously release of a person's invisible rays, which rays of light and general different, so that through the photographic film and photographic paper, Roentgen discovered with also different, in the absence of high-vacuum gas discharge and high voltage plus the conditions, able to uranium and uranium from automatic salt.

1896年，法兰西共和国物理学家贝克勒尔发表了一篇工作报告，详细地介绍了他通过多次实验发现的铀元素，铀及其化合物具有一种特殊的本领，它能自动地、连续地放出一种人的肉眼看不见的射线，这种射线和一般光线不同，能透过黑纸使照相底片感光，它同伦琴发现的伦琴射线也不同，在没有高真空气体放电和外加高电压的条件下，却能从铀和铀盐中自动发生。

The chemist made a vacuum in the bell jar when he exhausted the air from it.

Biot-Savart law is used to solve axial magnetic field generated by azimuthal current, this can avoid simulation difficulties due to expansion of simulation regions.

基于FLUENT软件对流体方程和电磁以及电子能量方程进行了耦合求解，从而实现了对真空电弧磁流体动力学模型的仿真。

However, Marshall[1] derived the Planck's black body radiation formula from classical theory without any quantum hypothesizes, and also She[2,3] derived directly the quantization of light energy in vacuum and the Planck radiation formula from classical electromagnetic theory.

可是，英国科学家Marshall却不借助任何量子假设而仅仅依靠经典理论就导出了Planck的黑体辐射公式[1]，中国科学家She也不依靠任何量子理论而仅仅根据经典理论就直接导出了真空中光能量的量子化，还能顺利导出Planck的黑体辐射公式[2，3]。

Which, as you can imagine, DIDN'T happen for my poor beautiful mum being dragged all the way to London to be dismissed by a professor she once trusted in a void of vagueness and bleakness who hadn't even looked at her scans before she'd left to make that dreadful journey.

其中，正如你可以想见，没有发生对我的穷人美丽的妈妈被拖入所有的方式到伦敦被解雇，由一名教授，她曾经信任的在真空中的含糊和bleakness谁hadn '吨，甚至看她的扫描之前，她要离开，使那个可怕的旅程。
