扩散的

The diffusion of mass or heat across two phases is extensively involved in chemical processes. Because of the effect of this kind of diffusion, there will be a inhomogeneous distribution of material concentration and then a gradient of interfacial tension will be occured on the interface of the two phases. When the gradient tends to a certain value, the natural convection would be induced derivatively, and orderly convective cells would appear in the system simultaneously. This is the so-called Marangoni phenomenon.

在化工过程中，广泛涉及到两相间的质量或热量扩散，由于这种扩散的作用，将在相界面处产生物质浓度的不均匀分布，从而出现界面张力梯度，这种梯度达到一定值以后，将出现派生的自然对流运动，并且在系统中呈现有序的对流胞结构，这就是所谓的Marangoni现象。

Furthermore, social progress and IT advancement strengthen the urban spatial diffusion. Such diffusion effect and the increasingly constant exchanges between city and its surrounding areas accelerate the extension of city and the integration of urban and rural areas.

The labor force in the tertiary industry disperses from urban core to its edge area within a distance of 15 km; oppositely it has a centralizing trend to inner city out of a distance of 15 km, especially in exurban area.

第二、三产业从业劳动力的分布变动互不相同：第二产业主要表现为由中心城区向郊区扩散的较大范围的单向均衡化变动；第三产业从业劳动力空间分布的变动则相对更向中心城区集聚，表现为在距离市中心15km圈内由都心区向其边缘区扩散、15km圈以外地区特别是远郊区则反呈趋向中心城区的集中化变动。

FRAP is a technique widely usedin cell biology to observe the dynamics of biological systems, including the diffusionof membrane components.

FRAP是在细胞生物学中被广泛用于测定生物体系动态性包括生物膜组分动态扩散的一种技术，其原理是利用高强度激光将细胞内一小部分区域的荧光分子漂白，然后通过记录该区域随后的荧光恢复，检测周围未漂白区域内的荧光分子与漂白区域荧光分子的交互扩散。

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。

The free bile acid and dihydroxy bile acid glycine union(exisistence by the of non-ionic form ) also be absorb again through the simple proliferation way.this may occurs in any part of the small intestine and colon.

未结合的胆汁酸和二羟基胆汁酸的甘氨酸结合物，也过简单扩散的方式被重吸收。这种通过小肠膜的非离子化扩散可在小肠的任何部位及结肠发生。

In addition,the mechanism isdiscussed on the prevention of interface diffusion via S-passivation.The FexS-dominateinterface reaction layer,is considered to prevent the reaction of Fe with As further meanwhilestabilizes the interface,therefore inhibits the diffusion from the substrate into Fe overlayer,which is different from the model of Anderson.

并且提出了S钝化阻止界面扩散的内在机制，认为在钝化层基底上形成的界面反应层，阻止了Fe和衬底As的反应并稳定了界面，从而阻止衬底元素向薄膜层的扩散，这与Anderson提出的模型不同。

The activity of catalysis of IER was affected by the chemical reactive process, it's inner and outer diffusion processes, serving time and esterified degree.
