在现今情况来看,国际间竞争的关系越来越激烈化,这种竞争关系实质上就是以科技力量和经济力量为基础的较量综合国力的一种形式,其竞争的主要竞争力归根结底也就是人才与人才之间的竞争。这种趋势下,要求我们必须要加强对我国人才的继续教育培养力度,以增强我国人才与国际上的技术人才相互较量的本钱,然而在这一问题上就又回到了继续教育和造就人才的关系上。对加大继续教育管理力度和造就人才的关系进行分析,仅供同行业人士参考借鉴,逐渐提升我国人才素质。 相似文献

EFFECT OF SMALL CLUSTER DIFFUSION DURING TWO-DIMENSIONAL THIN FILM GROWTH ON METAL SURFACE 总被引:1,自引:0,他引:1 下载免费PDF全文
The diffusion of small clusters such as dimers and trimers on metal surface and the growth of two-dimensional thin films are studied by Monte Carlo simulation, using realistic growth model and physical parameters. It is found that small cluster diffusion plays an important role in the process of thin film growth at not very low temperature. It affects not only the island density and the size of islands but also the critical value of saturation occurring during growth of thin films. The effect of small cluster diffusion depends on both the size of critical nucleus and the growth temperature. The simulation results also show that the larger the cluster allowed to diffuse, the easier the saturation that takes place, giving rise to the lower critical coverage of saturation occurring. It is suggested that the effect of small cluster diffusion should be included in establishing the growth models of thin films. 相似文献
