It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

同化实验对于台风眼区的螺旋形雨带贡献显著，说明TCFM云导风资料同化实验不仅有效调整了模式的垂直速度场，还对降水模拟有了明显改善。4通过理论分析，利用云粒子与极化降水粒子碰撞并弹离的感应起电机制和较大过冷云滴与雹粒碰冻并产生冰屑的温差起电机制下得到的E-Ir，由雷达、卫星遥感资料直接和间接同化模拟得到Ir，来反推E，了解雷暴云中闪电强度的平面分布，设置放电阈值为300KV/m，推算出放电的位置和首次发生闪电的时间。

To explore new synthetic methods, we set out a careful investigation of the reaction of benzimidazolium salt with many nucleophilic agents, including the active aromatic compounds and heteratom nucleophilic agents, and found that the quaternary C=N is not so active; when benzimidazolium salt is reacted with big nitrogen nucleophilic agent? phthalimide, it does not give the expected addition product, instead, produces N-alkyl phthalimide through alkyl-transfermation from benzimidazolium salt to phthalimide.

为了开发新的合成方法，研究了苯并咪唑盐与各种亲核试剂（活泼芳环与杂原子亲核试剂）的反应，发现苯并咪唑盐不与活泼芳环及杂原子亲核试剂发生2位加成反应；在与体积较大的位阻型N亲核试剂邻苯二甲酚亚胺反应时，未得到亲核试剂与极化的C＝N的加成产物，而是得到N烷基化的邻苯二甲酰亚胺，进一步研究表明，苯并咪唑盐将1（3）位N上的烷基转移给了邻苯二甲酰亚胺，并讨论了其反应机理和取代基，溶剂效应。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.
