迁移

The smaller the sizes of thediamond grains,the easier the electrins transports in diamond grains due to relativelysmall scattering.So,the ball-like films inlaid with nano-sized diamond grains had goodproperties of field emission.

尺寸越小的金刚石晶粒，电子在金刚石颗粒中由于存在较小的散射，电子的迁移越容易，所以具有纳米尺寸金刚石镶嵌颗粒的薄膜具有较好的场发射特性。

Electrons can be easily injected from thegraphitic matrix into the conduction rand of diamond under the high field which resultedfrom the projection field enhancemext.These injected electrons could reach the vacuumsurface and then emit into vacuum where the negative electron affinity or low electronaffinity could allow the electrons to re emitted more easily.

由于场增强效应，对镶嵌在非晶碳颗粒表面的金刚石晶粒来说，电子在高场作用下通过隧道效应越过金刚石晶粒与非晶碳形成的界面势垒，注入金刚石的导带，在电场的作用下迁移到表面，由于某些金刚石表面具有负电子亲和势或较小的正电子亲和势，电子较易发射进入真空。

Under this tectonic stress, the neotectonic movement of the basin is active. The main manifestations of the neotectonics include the formation of unconformities at the end of the Miocene, the Pliocene and Quaternary within the sequences, the shift of sedimentation centers, the strong fault activities, echelon pattern of diapir structures, mud volcanoes and earthquakes.

受该应力场作用，盆地新构造运动活跃，主要表现包括中新统末、上新统与第四纪之间及层系内部的不整合，盆地的沉降，沉积中心的迁移，断裂活动，底辟带的发育与分布，泥火山和地震等。

Migration of endothelial cells was significantly decreased in Dicer siRNA-transfected cells, whereas Drosha siRNA had no effect.

干扰Dicer表达后，内皮细胞迁移能力明显下降，而干扰Drosha则无此效应。

The X-ray double-crystal diffraction rocking curve measurements show the full-width half maximum of 180" and 185" for (0002) symmetric reflection and (10 12) skew reflection,respectively.A room temperature mobility of 850cm2/ is obtained for a 3μm thick GaN film.

Diffusion coefficient is one of the important parameters deciding migration prediction in migration model of compounds from food packaging material.

在食品包装材料化合物的迁移模型中，扩散系数是决定模型预测性的重要参数之一。

This leads to a relationship between the mobility and the diffusion constant called the Einstein relation.

这种恒定的迁移率和扩散系数之间的关系成为爱因斯坦关系。

In addition, the application of this diffusion and transport model is verified with experimental and engineering data.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
