The global bifurcation and chaotic behaviours are analysed using Melnikov technique, indicating that the random phenomenon of the channelling effect of the superlattice are related to chaotic behaviours of the system. 利用Melnikov方法分析了系统的全局分叉和它的混沌行为.指出了超晶格沟道效应的无规现象与系统混沌的相关性。
Shallow B+ as-implanted profiles can be obtained and channelling effect significantly suppressed by implanting BF2+ molecular ions into silicon, due to low effective boron energy. 用BF2~+分子离子注入n型硅,由于B的有效注入能量减少,可以得到B的浅注入分布,B分布的沟道效应也明显降低。

Through the proposed technique, channelling effect is reduced on the shell side of rotating tube bundle, a secondary flow similar to Dean vortices do exist in a rotating tube, and the heat and mass transfer efficiencies on the shell side are improved. 通过动态旋转技术,可以有效抑制管束间流体的沟流效应,同时管内流体将出现类似Dean游涡的二次流,从而使得管两侧的传递效果都将得到改善。
We should pay attention to thses influence factors in order bring their scientific channelling effect into full play. 我们应该重视这些影响因素使其发挥科学的导向作用。
