变化点

That is, the average size of scattering grains (the correlative interval at the first minimum point of autocorrelation function), the descending curve of the autocorrelation and the rectilinear asymptote of the autocorrelation at the large correlated interval changed regularly with the differential roughness of the scattering screen.

即当散射屏粗糙度改变时，散斑颗粒(自相关函数的第一个极小点所对应的相关间隔)的平均大小、散斑的自相关函数曲线的下降趋势和散斑自相关函数在大的相关间隔处的渐近值等都按一定的规律变化。

In the aspect of the force analysis between cycloid disk and pin wheel, a kind of force analysis method of the mesh with initial clearance is put forward in allusion to the teeth profile of the equidistant and radial-moving combining modification, which is more accord with the actual engineering.

该方法主要是从整个传动过程中动态地考虑摆线轮与针齿齿面的受力情况，依据摆线轮与针齿的实际最先接触点的分布区间不同，对不同的等距与移距组合修形方式分别给出了动态受力分析方法，并且在整个传动过程中进行了优化搜寻，从而得出了整个传动过程中的接触力动态变化规律，相对以前的受力分析方法，计算的精度和准确性得到了提高。

This controller has good robustness to disturbances of power system.

Duane Kuang: This is a big topic, a few changes.

邝子平：这也是一个大话题，几点变化。

Methods RPE cells were exposed to shear stress of 2 dyne/cm2 for 0, 0.25, 0.5, 0.75, 1, 1.5, and 3 h. Reverse transcription polymerase chain reaction was used to detect the levels of c-fos and c-myc mRNA in RPE cells. One-way analysis of variance was used to compare the differences.

用2 dyne/cm2的剪切力作用于体外培养的人RPE细胞，作用时间分别为0、0.25 h、0.5 h、0.75 h、1 h、1.5 h和3 h，采用逆转录聚合酶链反应观察c-fos和c-myc mRNA的表达变化，并采用单因素方差分析比较各时间点之间表达的差异。

The 2-D transfer function of the bistatic SAR is obtained. Azimuth position distortion along range existing in the original alogrithm is corrected by mapping from scene coordinate to azimuth-slant distance coordinate. Bistatic SAR date can still be processed by a mono-static SAR processor. The efficaciousness of the proposed algorithm is verified through point target simulations.

算法通过数值计算得到双基地二维传递函数，通过场景坐标系向方位－斜距平面的映射校正了原算法中存在的沿距离变化的方位位置畸变，进而来用常规单基地SAR成像处理流程实现对双基地SAR回波数据的成像处理，最后通过点目标仿真验证了算法的有效性。

Femoral stress has been studied by electrometric experimental stress analysis methods to know about femoral stress value and its distribution case in front and rear of replacement to artificial femoral head.

结果表明：股骨内外侧应力大于前后侧应力；人工股骨头置换术后股骨头近端应力明显下降；在使用骨水泥固定后，股骨上各点应力无大的变化，而当使用带颈领的人工股骨头时，股骨头近端应力下降受到抑制。

In order to understand its ecological adaptability, Iodimetry which can be measured the oxygen content in the water is undertaken to determine the Elodea nuttallii's light compensation point under the temperature of 10℃、15℃、20℃、25℃ and 30℃.

为了解其生态适应性，采用碘量法测定水中含氧量来研究它在10℃、15℃、20℃、25℃和30℃的温度下其光补偿点的变化。

Teacher: Well, if it is, he's changed enormously.

如果真是那样的话，他的变化也太大了点。

By the numerical methods, the efficient and reliable numerical axisymmetric models have been established, especially the inner core passage, the effect of blade entrance angle and fan nozzle pressure ratio on thrust reverser effectiveness and discharge coefficient is investigated, the calculated results and the available experimental data are compared.

本文建立了外涵叶栅反推器的轴对称计算模型，给出了内涵计算域的有效处理方法，利用数值模拟手段研究了叶片几何进气角、外涵入口压比的变化对反推效率、流量系数等的影响规律，并将计算结果与可能得到的试验结果的数据点进行了比较。

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。
