Our main work is as follows: the stable laser mode theory in uniform plasmas is extended to non-uniform plasma cases; the discussion of the sufficient and necessary conditions for laser self-focusing in uniform plasmas is developed to non-uniform plasma cases; a quantitative approach to judge the impact of different plasma density distribution on laser self-focusing is proposed; the evolution properties of asymmetric laser filed in non-uniform and uniform plasmas are discussed and mechanisms that symmetric channel-like plasmas can confine the laser centroid around the plasma channel axes and symmetrize initially asymmetric laser beams are proposed; the formation of solitary standing wave in moderate plasma density is studied by PIC simulations and can be explained by stimulated Raman scattering of laser beams in plasmas.

主要工作为：把均匀等离子体中激光的稳定模理论推广到横向非均匀等离子体情形；把均匀等离子体中激光自聚焦的充分和必要条件的讨论推广到横向非均匀等离子体情形；给出横向密度分布不同的等离子体影响激光自聚焦的定量判据。讨论了初始不对称的激光场在横向非均匀及均匀等离子体中的演化特性，并提出了具有对称腔道结构的等离子体箍缩激光质心和对称化初始不对称激光场的物理机制。用粒子模拟讨论了激光场在等离子体中形成孤立驻波的过程，认为前向受激拉曼散射是发生此现象的可能机制。

It has been shown that tautomerism has a significant effect on the QSAR modelling, and the models obtained from 1H-indazol tautomeric form always represent higher quality than those from 2H-indazol tautomer, which indicates that 1H-indazol tautomer of the indazolyl urea is probably the active form when binding with the TRPV1 channel protein. It has also been demonstrated that the theoretical descriptors derived from electrostatic potentials on molecular surface together with the GETAWAY descriptors can be well used to express the quantitative structure-activity relationship of indazolyl urea TRPV1 channel antagonists.

结果表明：互变异构对QSAR结果具有一定的影响，采用1H-吲唑异构形式得到的模型，在质量上均高于采用2H-吲唑异构体，预示着1H-吲唑异构体更有可能是吲唑脲类分子的活性异构形式；分子表面静电势参数结合GETAWAY参数可以较好地用于描述TRPV1通道拮抗剂分子结构与其活性间的定量关系。
