尘埃

The reason of this is that near the horizon we look through a very great thickness of the lower atmosphere, which is full of the larger dust particles reflecting white light, and this diluter the pure blue of the higher atmosphere seen beyond, And in the vicinity of the sun a good deal of the blue light is reflected back into space by the finer dust, thus giving a yellowish tinge to that which reaches us reflected chiefly from the coarse dust of the lower atmosphere.

这是因为我们向天边望去时，目光要穿过极厚的低空大气层，其中布满颗粒较大的尘埃，反射出白光，这就冲淡了天际高空大气层的纯蓝色。在太阳附近，大量蓝光则由细微的尘埃反射回太空。这样，主要由低空大气层的粗粒尘埃反射到地面的光线，便带有浅黄色。

In the present thesis, firstly, the dispersion relation of an infinite dusty plasmas is studied, it is found that the effects of adiabatic variation, the external magnetic field, the particle collisions and the obliqueness have strong influence on dusty low frequency waves.

本文首先研究了无界尘埃等离子体中低频波的色散关系，发现尘埃绝热电荷扰动、外磁场、粒子碰撞和斜传效应对尘埃低频波都有强烈影响。

But the sun's rays then reach us despite having passed, first, through an enormous thickness of the higIT strata of the air, the minute dust of which reflects maximum of the higIT strata of the air, the minute dust of which reflects maximum of the blue rays away from us, leaving the complementary yellow light to pass on, Then, the somewhat coarser dust reflects the green rays, leaving a abundance orange-coloured light to pass on; and finally some of the yellow is reflected, leaving almaximum pure red.

这就充分呈现了低空尘埃的数量之大。但是太阳的光线终于到达了地面。它们先是穿过厚度极大的高空大气层，其中的细微尘埃把大部份蓝色的光反射掉了，让补色的黄光继续通行。然后，粗粒尘埃又反射掉绿色的光，让偏橙色的光继续通行。最后，部份黄色的光也反射掉，剩下几乎是纯红色的了。

There are two focus included as the following two topics:The measurement of equilibrium charge of dust particles in the plasmas By studying the forces acting on dust particles at the equilibrium position, where, the electric force and gravity force are importantly considered, the equilibrium charge of dust particles can be presumedly calculated according to the relation of the forces.

文中着重进行了以下两个方面的研究：一、等离子体中尘埃粒子平衡电荷量的测量通过研究尘埃粒子在平衡位置处的受力情况确定尘埃颗粒所带的电荷量。主要考虑两种力的作用即尘埃粒子所受的电场力和重力。根据这两种力的平衡关系就可以粗略得出尘埃粒子在平衡位置处的电荷量。

By a theoretical model, influences from electron temperature, ion temperature, plasma flow and secondary electron emission are mainly analyzed.

主要讨论了电子温度、离子温度、等离子体流动以及二次电子发射对尘埃带电的影响；数值计算研究了尘埃带电的弛豫时间；在考虑了离子拖拽力作用下，估算了尘埃粒子在聚变装置中的运动速度；针对碳材料的尘埃理论计算得到了粒子的寿命。

In this thesis, an unmagnetized, collisionless dusty plasma which consisted of extremely massive, highly negatively charged dust particles, ions and electrons are studied. Considering the effects of hot dust fluid with non-thermal ions and variable dust charge, we study the self-consisted system parameters on the structures of the dust-acoustic solitary waves by reductive perturbation methods.

本论文研究无磁化、无碰撞的、由大质量且带负电量的尘埃颗粒、电子和离子组成的尘埃等离子体，考虑尘埃流体的温度、非热离子和尘埃颗粒电荷绝热变化的因素，使用约化摄动方法研究这个自洽的系统的参数对尘埃声孤波结构的影响。

It is investigated with regard to narrate tactics,personage image,poem speciality that how Alai expresses in fable fashion such a process that people is the dust,life is the dust, the war is the dust, the lust is the dust,the wealth is the dust and everything is equally the dust which links the historical process,and ascending like the dust,setting off from and returning to the earth with the new melody again after the quietness.

笔者主要从叙事策略、人物形象、艺术表现三个方面来初步探讨阿来是如何用寓言化的方式来表现&人是尘埃，人生是尘埃，战争是尘埃，情欲是尘埃，财富是尘埃，而历史进程中的每一个环节同样是尘埃，像尘埃那样升腾、飞扬、散落，始于大地而又终于大地，寂静之后便又响起新的旋律&这个过程。

Methods The chest of the confirmed diagnosis of 101 cases of silicosis and 6 objects of observation were radiographed by the CR high thousand voltageand and the tradition high thousand voltage. Refereing to Diagnostic Criteria of Pnemoconioses and 23 chest standard films, we evaluated every radiograph quality and divided the period of silicosis at random.

将已确诊的101例肺尘埃沉着症患者和6例O+患者，采用CR高千伏和传统高千伏两种方法，各摄胸部正位片1张，由肺尘埃沉着症诊断小组，按照肺尘埃沉着症病诊断标准(GBZ 70-2002)及23张标准片，随机对每张胸片质量和肺尘埃沉着症诊断及其分期进行评定。

This is not an ordinary box, which is used as a background picture of the dialog box, very pretty.

详细说明：这可不是一个一般的对话框，它是用图片作为背景的对话框，非常好看。

Conceal me what I am,and be my aid for such disguise as haply shall become the form of my intent.

遮掩我的身份，帮助我，我的面具将成为我的目的。
