等离子体

Objective To develop a new technique of air purification by plasma combined with photocatalysis.

目的 研究一种新型的等离子体－光催化复合空气净化技术。

The "Phoenix" was just one of the dramatic "pictorial" crop formations which appeared in the fields of England last summer--and to our surprise the plant samples taken from it (and several of the other equally astounding formations) showed clear evidence of exposure to a plasma discharge: stunted and poorly-developed seed-heads, massive apical node elongation, expulsion cavities and--in several cases--node bending which could not be attributed to phototropism/gravitropism.

"凤凰"只是其中一个戏剧性的作物结构"图案"，去年夏天出现在英格兰的田地-和令我们吃一惊的是取自它的植物样本（及几个其它同样惊人的结构）显示清楚的证据，曾在一等离子体放电下暴露：发育迟缓和弱发展的种子头，大量的顶上茎节延伸，驱逐凹处及-在一些情况下-茎节弯曲并不能归因於向光性/重力影响。

To study the application of plasma in techniques of screening, a model simulating slanting the incidence of plane electromagnetic wave into plasma slabs with metal underlay is adopted.

研究等离子体在隐身技术中的应用。

Irradiation from a Q-switched Nd: YAG laser (pulse duration: 12 ns, repetition rate: 10 Hz) was focused onto the sample surface by a plano-convex lens with a spot diameter of about 1 mm to ablate a portion of sample and generate a micro plasma.

一个平凸透镜把斑直径大约为1 mm的光量开关Nd： YAG激光器（脉宽：12 ns；重复频率：10 Hz）辐照聚焦于样品表面，用来烧蚀样品的一部分，形成一个微等离子体。

He is very interested in plasma physics.

他对等离子体物理学很感兴趣。

It is necessary to develop some new plasma sources to meet the development of semiconductor technology.

为适应半导体技术的快速发展，需要寻求一些新的等离子体源。

It is estimated that more than 99% of the matter in the universe exists in the plasma state.

据估计，宇宙中99%以上的物质以等离子体的状态存在。

Finally we point out the research and development of the plasma position control in future.

在文末，我们指出了等离子体位移控制研究的进一步发展。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
