Through numerical calculation and comparison with the complete formula,the accuracy of the approximate formula for calculation of reflection coefficient often used in AVA method for gas hydrate is discussed.

通过与完整公式的对比，对AVA常用的反射系数近似计算式的精度进行了讨论，同时分析了地震波速度、泊松比、密度等参数对于BSR反射系数的不同贡献。

The thickness of aqueous diffusion layer d(subscript a and diffusion coefficient (d0) of Hg through SLM were evaluated by the linear slope method, and they were found to be 1.57×10^(-5) m and 7.26×10^(-13) m^2/s, respectively.

Hg在N503-煤油支撑液膜体系中的扩散层厚度δa为1.57×10^(-5)m，膜内扩散系数d0为7.26×10^(-13)平方公尺/s，确立了Hg的渗透系数P方程。

固然，有须要指出，质量系数不是丈量图片质量的准确标准，只是如果另存为网页格式和另存为都是基于jpeg标准附录中的量化表的线性丈量，那末质量系数是独一能用来比力图片质量的参量。

With the increase of the refractive error before refractive surgery, the asphericity of the anterior cornea changes from negative to positive, which leads to the increase of the spherical aberration.

考虑了激光斜入射和反射后的术后非球面系数与Munnerlyn公式的预期值差别不大，术后非球面系数的大小与光区的关系不大。

In order to represent accurately and concisely the changing characteristics of one-dimensional spectrum density function in the chatter development. This thesis, for the first time, proposes the Edgeworth asymptotic expansion formulas of spectral density. A detailed proof is given. Some new statistic including spectral skewness, spectral kurtosis and spectral cumulants are proposed.

为了准确、简洁地表达一维谱密度函数在切削颤振建立过程中的变化特征，论文首次建立了一维谱密度函数的Edgeworth渐近谱展开式，给出了详细的证明；并由此提出了"谱偏态系数"、"谱峰态系数"和"谱累积量函数"等新的谱统计量。

Furthermore, the larger the atomic lattice, the smaller the sliding friction coefficient is.

滑动摩擦系数随晶格常数的增加而降低，而当晶格常数较大时，其变化对滑动摩擦系数影响较小。

Strata quality factor and attenuation factor especially these of near surface, are studied.

对松辽盆地南部的地层品质因素和地层衰减系数、尤其是近地表的地层品质因素和地层衰减系数进行研究，进而研究了野外地震采集的激发和接受等各个因素。

However, as Fama and French (2002) note, the time-series standard errors of the coefficient estimates can be biased downward by autocorrelation in the coefficient estimates.

然而，由于和法国法玛（2002）注意到，该系数估计时间序列的标准差可以向下偏估计的自相关系数。

Objective To explore application of spatial autocorrelation and local indicators of spatial autocorrelation in disease.

目的 探讨空间自相关系数及区域型空间自相关系数对疾病的空间数据聚集性的应用。

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。
