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。

The apoplasmic charater of ectomycorrhizal roots of Larix seedlings infected with Paxillus involutus was examined using the cathnic colloidal gold. The result showed the density and distribution of anionic binding sites were different in sheath and Hartig net. The negative charger in the outer part of the sheath was slightly low. It increased graduately from outer to inter sheath. The negative charger density rised higher in the inter part of the sheath and then decreased graduatedly from the sheath to Hartig net. This may be related to nutrient uptake and atransport in ectomycorrhizal roots.

利用阳离子胶体金探针研究日本落叶松和卷缘桩菇形成的外生菌根质外体的特性，结果表明，外生菌根质外体负电荷分布是不均一的，在菌套外侧负电荷比较低，向内侧逐渐增高，在靠近单宁层菌套菌丝细胞壁负电荷密度最高，再向内侧过度到哈蒂氏网又呈现出明显逐渐下降的现象，而且在哈蒂氏网负电荷主要分布在植物的细胞壁，真菌菌丝细胞壁负电荷很少。
