On thebasis of the relationship between the diffusion coefficients and the mean free path of gas molecules, it is foundthat the macro-parameters of gas diffusion is determined all by the micro-parameters of gas molecules.

分析了前人测定的不同压力下瓦斯在煤体中的扩散系数与分子平均自由程之间的关系，表明孔隙气体在煤微孔隙中扩散的宏观参数从根本上来看是由于分子微观参数的改变引起的。

In the study of thin-film conductors,ion diffusion is an important phenomenon as electrodiffusion degradation can lead to metallization failure.

在薄层导体的研究中，粒子的扩散是一类重要的现象，由于电扩散的降解能导致金属的毁坏。

In addition, a thin film made between the microelectrode and the substrate was used to minimize the diffusion of the HRP in solution.

同时在工作中为了减小HRP扩散所引起的微米点的扩大，在UME与基底之间形成一厚度为10μm左右的液膜，减小了分子扩散对结果的影响。

The nasalization distinguishes itself in four aspects, including the nasal spreading can be bi-directional, the nasal spreading exhibits different situations between open and close syllables, vowels preceding nasal codas can not be nasalized, and postvocalic glottal stops and glides must agree with nasal onsets. The literature background is based on seven proposals, including Lin's (1992) proposal, Li's (1992) right-spreading theory, Wang's (1995) bi-directional spreading theory, Ang's (1996) downward-spreading theory, Chung's (1996) domain percolation, Ang's (2001) and Chou's (2002) OT analysis.

闽南语鼻音主要有四个特徵：闽南语鼻音扩散可以是双向的；闽南语鼻音在开音节与闭音节里呈现不同的扩散现象；鼻音化子音前的母音无法受到鼻音化；元音后喉音及滑音必须与韵首子音行形成鼻音上的和谐。

It was found that the partial pressure of Hg could influence As diffusion and Hg vacancies in epilayers assisted fast diffusion of As. The As diffusion at a lower temperature of 240℃/24～48 hrs was negligibly slow.

研究表明在低温段的240℃/24～48小时的退火中As的扩散非常有限，对样品中As的浓度分布影响不大，而在高温段380℃/16小时和440℃/30分钟退火中，As扩散较为明显，能使原来的PN突变结变缓。

The diffusion coefficient of niobium is much smaller than that of titanium, which requires more time to be absolutely homogenized.

元素扩散计算结果表明，提高均匀化温度可以提高元素的扩散系数； Nb的偏析系数比Ti的小得多，达到完全均匀化需要很长的时间。

Local polynomial estimation method is a kind of a nonparametric estimation methods which are based on data-analytic approaches.

我们提出了时齐的扩散过程的漂移项和扩散项的局部多项式估计。

The numerical solutions for different coefficient and different boundary conditions are obtained for two models of radon field which have respectively source in the side and inside of collapse column.

根据流体场的扩散理论和对流理论，建立了扩散系数与对流速度为常量或变量情况下的氡气场三维状态方程；对于陷落柱柱体侧面有源氡气场和柱体体内有源氡气场两种理论模型，给出了不同系数和边界条件下的数值解的形式。
