扩散

The underline mechanism of diffusion and nucleation also be studied. Electroscopic imaging in transmission electron microscopy shows that SiOx act as a one-way diffusion barrier in oxide-mediated silicidation which only allows Co diffuse into Si substrate but inhibits Si diffuse out.

我们并针对其形成机制作探讨发现，氧化介层形成一个单向的阻绝层，只允许钴扩散进入矽基材，但阻挡矽向外扩散。

Solute diffusion controlled solidification model was employed to simulate the columnar to equiaxial transition of TiAl alloy casting. The simulation results show that solute shock wave occurs when the diffusion fields of columnar and equiaxial dendrites meet.

利用溶质扩散控制模型对TiAl合金柱状晶/等轴晶转变过程进行了数值模拟，结果表明，等轴晶在柱状晶前沿形核及生长过程中，当两个扩散场相遇时，观察到成分冲击波，它可能是导致柱状晶停止生长的一个主要原因。

The diffusivity of ethanethiol in flexible MOR is higher than that in flexible MFI, because the 12 member ring in MOR is larger than the 10 member ring in MFI.

对比这两种沸石，MOR中的扩散系数要比MFI沸石中大，这是因为乙硫醇分子在MOR12元环中扩散更易进行所致。

A precondition was that the stand diameter grew 2 cm every year. For Evodia meliaefolia community, in the competitive living space by close cover stand, the ratio remained low for ten years with little fluctuation. However, in the unlimited open space, the ratio reached two peak values, with the first appearing in the eighth year, and the second in the eleventh year.

在假设了楝叶吴茱萸和油茶每年胸径生长2 cm的前提下，楝叶吴茱萸冠层总面积变化规律是：在郁闭林分被抑制的生长空间里，楝叶吴茱萸冠层总面积扩散速率可以长达10多年基本维持在一个很低的水平下，而且基本没有太大的变化；在获得充分开阔的生长空间里，楝叶吴茱萸冠层总面积扩散速率出现两个增长高峰，一个出现在第八年，一个出现在第十一年。

Based on the theory of technical innovation and technical innovation diffusion elaborated, as well as fluxionary calculus and game theory, the thesis analyses corporation adoption with game theory in the process of technical innovation diffusion: analyzes in the situation of information symmetry and information asymmetry the gambling between the supplies and the latent users of innovation, discusses the mechanism of the phenomenon "reversion choice" with emphasis in the situation of information asymmetry, and also introduces signal transmission model and information screen model to realize Pareto improvement; at the same time it analyzes in the situation of complete rationality and limited rationality the gambling between the latent users of innovation.

依据已阐述的技术创新和技术创新扩散理论，以及微积分、博弈论等相关理论，对技术创新扩散中企业采用行为进行了博弈分析：分析了信息对称和信息不对称情况下创新供给者与创新潜在采用企业之间的博弈，重点讨论了信息不对称时&逆向选择&现象发生的机理，并引入信号传递模型和信息甄别模型以实现帕累托改进；同时分析了完全理性和有限理性情况下创新潜在采用企业间的博弈。

States Gaede s invention patent and the evolution history from the early mercury diffusion pump to oil fractionating diffusion pump .

本文叙述了盖得的发明专利，从初期的汞扩散泵到分馏油扩散泵的演变过程。

Using glyoxylic acid to replace the harmful chemical substance such as formaldehyde as a reducing agent, an electroless copper plating on difficulty deposited substrates was fulfilled, which including Al,Ti and wafers having TiN and TiSiN as the barrier layers.The surface morphologies and grain structures of copper deposits prepared were analyzed.

摘 要：采用乙醛酸代替有害的化学药品作为还原剂的化学镀技术，在工业纯铝片、工业纯钛片、以TiN作为扩散防护层的硅片和以TiSiN作为扩散防护层的硅片等难镀材料实现了化学镀铜。

There are two basic directions. One is Bass mode based on the product diffusion ,which can not fully explore the regularity. The other is raised by Golder who developed the take-off concept and made a great moving by the survival analysis.

目前研究分支有：以产品销售扩散研究发展成的经典的Bass模型，但产品销售起飞本质上是个二分事件，所以扩散流派并没很好倡导和揭示起飞机理；Golder等人不仅提出起飞概念，而且在研究方法上借用生存分析等技术，并取得重大进展。

The experiments reveal that solvent outflow is controlled by the system's viscosity while non-solvent inflow is controlled by the hydrophile of the interface.

实验表明，溶剂外扩散受控于体系的粘度，非溶剂的向内扩散受控于界面的亲水性。

And the degree of a species niche hypervolume diffuse within the niche space is described with niche diffusion index.

物种的实现生态位中心点到理论生态位中心点的距离称为生态位偏离，而物种在生态位空间扩散程度以生态位扩散指数表示之。
