The first is termed aero-optic and involved optical transmission through aberrating fluid layer whose thickness, L, is smaller than or comparable with the viewing aperture dimension, A, and the turbulence scales, A , are smaller than or the order as the layers thickness:The second category, atmospheric propagation, involved optical transmission through the aberrating medium over very long propagation distance compare with the viewing aperture size, and the turbulent scales of note are generally less than or the same order as the propagation distance:Depending on the atmospheric conditions, for ground-based observatories, wave-front sensor operating at 300HZ can adequately resolved both the important spatial scales and the temporal evolution of the atmospheric-turbulence-induced aberrating wave front over viewing aperture associated with relatively large telescope.

第一类问题光学畸变发生在&近场&较短的光路上，即流层厚度L，光束直径A，以及湍流尺度Λ三者之间存在关系式：ΛA≤L≤A第二类大气传输问题光学畸变则发生在较长的一段光路上，L，A，以及Λ满足： A＜＜Λ≤L对于地基情况下的大气光学传输，300Hz的波前传感器就能实时地测得光波前畸变包括时间、空间频率的相关信息，为我们的自适应光学系统的设计、制造以及进行相关的自适应校正都有着相当重要的指导意义。

This paper presents an overview of recent and on-going evolutions in the X window system.

The prediction of the grape disease is a typical nonlinear system, and there are also many factors to result in plant disease..

葡萄病害发生的猜测是一个典型的非线性系统，影响病害发生因素又很多，采用常规方法猜测将是一件非常困难的事。

The power net is injected high frequency impulse signal online from voltage transformer connected to substation bus after the fault of single-phase grounding take place,and then the echo traveling wave from the fault spot corresponding to the high frequency impulse signal is captured by the fault detector installed in the substation.

配电网作为电力系统给用户供电的一个重要环节，它直接给用户提供高质量和可靠的电能，配电网在发生单相永久接地后，为防止发生多点接地短路故障，必须尽快确定故障线路及故障点到供电所的距离，这就是小电流接地电网故障定位问题。

Suppose the system went wrong (system frequency saltated at 100s and then recovered at 200s), the Wavelet function of signal processing is Daubechies Wavelet.

假设系统工作到100s时发生故障，频率发生突变，持续到200s时恢复正常，信号分析采用的小波函数为Daubechies小波。

Experiments were also performed to study the IIF behavior of microcapsules of various sizes by the cryomicroscope. It was observed that the microcapsules behaved as osmometers that water migrated across the cell wall when there was an osmotic potential. During freezing, IIF phenomenon of microcapsules occurred immediately after the ice front touched the microcapsule following the seeding of the supercooled solution.

在本研究中亦以褐藻酸钠为材料制作不同大小微胶囊以模拟人工细胞，并以低温显微镜系统进行其低温冷冻实验，实验结果显示微胶囊会因为内外渗透压不同而发生水分迁移现象，且当触发囊壁外过冷水溶液时，囊壁外冰晶形成会随即造成微胶囊发生细胞内冻结现象。

So when unit 2 failed will be the occurrence time of totalfailure of this two-unit system.

所以，元件2故障发生时也是双元件系统整体故障发生的时点。

Tobacco tomato spotted wilt disease was found in many provinces.This disease is widely distributed in Yunnan production tobacco area and it causes above 60% losses in some area. The tomato spotted wilt disease is one of the most potentially dangerous disease of tabacco in the world. This paper reviewed the distribution,symptomology, causal agents, pathogenic mechanism, the composition and function of virus genome and epidemiology and management of the tobacco tomato spotted wilt disease.

目前该病在中国许多省均有发生的报道，在云南烟区广泛分布，在局部地区可造成60%以上的严重损失，烟草番茄斑萎病被认为是世界上对烟草最具潜在危险病害之一，较为系统全面的综述了烟草番茄斑萎病的发生与分布，病害症状学，病原物，致病机制，病毒基因组结构和功能以及病害的流行及控制等方面的研究进展。

The problem considered in this paper contains absorbing-emitting medium, absorption and emission of radiation not only exist on boundary of the system, but exist in the whole space fulled of medium, variation of temperature, pressure, density, compusure and property with coordinates must be considered in computation, so computation in this paper is based on three dimensional flow field.

本文所计算的问题包含吸收-发射性介质，能量的吸收和发射不仅发生在系统的边界上，而且还发生在充满介质的全部空间，在计算中要考虑介质中各点的温度、压力、浓度、成份以及物性在空间上的变化，因此本文的计算是根据三维流场计算的数据进行的。

According to the fault data information and expert"s field knowledge, the system can distinguish the lines and buses which fault occurs in, also judge the line"s fault type and the circuit breakers and relayss action performance and give the maintenance suggestion.

系统能在电网发生故障时，根据故障数据信息和专家领域知识，判别发生故障的线路、母线，线路的故障类型以及断路器、保护的动作性能，并给出维修建议。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
