Resonant laser ablation is a two-step process, occurring within a pulse of a tunable laser, in which the leading edge of the laser pulse ablates the surface of the solid sample to produce neutral atoms or molecules that are then resonantly ionized by the trailing edge of the same pulse.

共振激光烧蚀技术是指发生在同一激光脉冲时间内的两步过程，它是指用波长可调谐的染料激光取代固定波长输出的激光，并调谐激光输出波长实现所研究原子或分子电子态之间的共振跃迁，激光单次脉冲的前沿对样品进行烧蚀，烧蚀的物质在激光光束内形成粒子气团，同一次激光脉冲的后沿实现对气相原子或分子的共振电离。

Om the subatom microcosmic particles to the integrated big universe, assimilating to the turbulence field sufficing Navier-Stoke Equations of hydrodynamics, this paper has put forward a series of fully different viewpoints with the modern physics, under the foundations, established the Astro-Unitive Field Equations.

对宇宙物质的认识，从微观亚原子粒子到整个宇宙，与流体力学的服从Navier-Stokes方程的湍流场比拟，本文提出了一系列与当今物理学绝然不同的观点，在此基础上，建立了宇宙统一场方程。

Since the teensy particles only weakly interact with ordinary matter, they are thought to easily fly through the sun's core toward the surface unimpeded by other particles.

由于跟普通物质之间只是发生微弱的相互作用，这些微小的轴子能够很容易地穿过太阳核心，朝着表面飞去，不会受到其他粒子的阻拦。

However, although antiparticles can be and are created in the laboratory, this has never been done in sufficient quantity (less than one trillionth of a gram to date) to form what we would think of as antimatter.

然而，尽管反粒子可以而且已经在实验室中创造出来，却没有得到充足的质量（到目前为止所得仍小于一万亿分之一克）以形成我们所谓的反物质。

On elementary theory of non-thermal plasma, the mechanism of VOCs destruction was decided: under the action of activated particles (such as high-energy electrons, ozone, radicals, etc) produced by discharge reaction, a series of physical and chemical reaction will take place, the result is that harmful VOCs is decomposed into unharmful substance.

根据电晕放电等离子体的基本理论，得出了等离子体处理VOCs的机制：在放电产生的活性粒子(如高能电子、臭氧、自由基等)的作用下，发生一系列的物理化学反应，使有害的VOCs转化成无害的物质。

This paper introduced a magnetically confined plasma teaching experimental device. Its main frame is made up of a spherical glass vacuum discharge chamber. It can gain the direct current glow plasmas of the audio-visual.

等离子体是继固体、液体、气体之后物质的第四种聚集状态，是由大量的带电粒子组成的非约束体系，其有别于其它物态的主要特点是长程电磁相互作用起主导作用。

Particles deposited in the alveoli are immediately subjected to coating by surface active lipid materials.

当粒子沉淀到肺泡中时，立刻会遭到表面活性的脂质物质的复盖。

To see dark matter, said Dr. Barish, scientists will have to build the world's biggest particle accelerator.

巴里斯博士说，科学家们必须建造世界最大的粒子加速器才能观察到暗物质。

RESULTS: Gold nanoparticles with good particle size were prepared by using a rate of sodium citrate to chloroauric acid was 6:1.

结果：制备金纳米粒子时，当柠檬酸钠和氯金酸物质的量比为6：1时，纳米粒子粒径均一。

It was concluded by the X-ray photo spectroscopy that the friction performance of metals could be improved by the lube containing nanosize CaCO3 particles due to the coaction of three matters CaCO3, CaO and Ca during friction process.

通过X射线光电子能谱法得出：含有纳米碳酸钙粒子的润滑油，在摩擦过程中通过碳酸钙、氧化钙、钙三种物质共同作用提高金属的摩擦学性能。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
