BmK IT2 associateed with and dissociated from its binding sites on insect synaptosomes quickly in two phase kinetic manner, and its specific binding was independence of membrane potential, but could be significantly inhibited by native BmK IT2, BmK AS and BmK AS-1 in a dose-dependent manner, and only partially by BmK Ⅰ or veratridine at high concentration.

BmK IT2能以两相动力学方式快速与昆虫突触体结合和解离，且其结合不依赖于膜电位，可分别被天然毒素BmK IT2，BmK AS和BmK AS-1剂量依赖地抑制，另也可被高浓度BmK Ⅰ和藜芦碱部分抑制。

By virtue of the coordination of Cr2L (L = CO; PPh3; C3H5 BF4-) with N-vinylcarbazole, acenaphthylene and their derivatives as organic ligands, a series of organometallic complexes have been synthesized. Their spectra characterization and X-ray diffraction analysis have been performed. It is found that this kind of complexes possesses an electronic structure with highly extensive π- delocalization.

The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

该离聚体膜显示出良好的CO_2渗透性能，在20℃和0.05MPa压差下，CO_2渗透系数P_(CO_2)和CO_2/N_2分离系数αCO_2/N_2分别高达223 Barrer和65.70.P_(CO_2)和αCO_2/N_2随CO_2压差的降低而明显增大，显示出促进输送特征，这一行为即使在膜放置2个月之后并不消失，渗透分离性能变化不大。N_2和CH_4无此性能，因此在气体压差较低时，P_(CO_2)和αCO_2/N_2、αCO_2/CH_4可同时提高。

Based on studies of RCM reaction of 50 and CM reaction ofacrylonitrile with 1-octene or 1-decene catalyzed by pyridine derivative-coordinatedruthenium benzylidene complexes, it can be concluded that ruthenium benzylidene complexwith the more labile dissociating ligand exhibits the higher initial activity and better catalyticperformance.

Ionomer membrane containing cobaltous ions, exhibiting CO2 facilitated transport and higher acoi/M value are not ample conditions, but are important factors.

离聚体膜含有钴离子、对CO_2具有促进输送作用以及具有较高的αCO_2/N_2是重要的因素，但还不是充分条件，还可能同时与高分子膜的化学结构、聚集态结构及未知因素有关。

Ionomer membrane containing cobaltous ions, exhibiting CO2 facilitated transport and higher acoi/M value are not ample conditions, but are important factors. The key reasons for the occurring of reverse permeation behavior should be attributed to the polymeric chemical structure and the morphology structure of the membranes as well as other possible unknown factors.
