The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst.

分子内季铵盐和吡啶盐具有相转移能力，对于取代色烯不对称环氧化的作用与外加的吡啶盐和卤化铵的作用相似，使Mn催化剂催化取代色烯环氧化反应的活性明显提高。

Poly(1-alk-1-viny pyridinium halides) have also been shown to be good negative electron beam resists with sensitivities as high as 5uCcm-2 in a 20kV electron beam and line widths as low as 0.3um.

波河 (单一 alk 的-1-葡萄树的 pyridinium 卤化物)也已经被显示很好否定的电子光线以敏感 20 仟伏电子光线和线宽度的像 5uCcm-2 一样的高度像 0.3um 一样的低点抵抗。

The enhancement of the reaction activity is attributed to the phasetransfer capability of the built-in quaternary ammonium and pyridinium salts of theMn catalyst. The effect of the internal quaternary ammonium and/or pyridiniumsalt on the epoxidation of substituted chromenes is similar to that of the externalpyridinium salts and ammonium halides.

The results show that the rearing larvae of Penaeus vannamei is related to both the water quantity change and the change of ponds, expecially to the kind and the amount of diets. During the microencapsulated diets used, diets of "OK" brand are better than that of "Bonasse" brand. The diet blended with 80%"OK" brand and 20% rotifera is the best.

主要是与投喂饲料的种类及用量有关：在所使用的微囊饲料中欧开牌饲料比博尚牌饲料的育苗效果好，其中80%欧开牌微胶囊饲料和20%卤虫配合使用培育凡纳对虾幼体的效果又是最佳的。

All emergence index were higher markedly than control group (P.05), besides, the shrimp larvae showed high quality anduniformity, the amount of "OK" brand that was used in every group during cultivation was 48.34%,58.50%,48.81%,and 49.5% less than that of "Bonasse" brand, however, the former had the better larval nursery effect than the latter obviously. It was more recommendable that using the compound blended with formulated diet of 80% microencapsulated diets of "OK" brand and 20% rotifera than only using microencapsulated diets of "OK" brand.

另外，在培育过程中投喂欧开牌微胶囊饲料的各实验组其饲料投喂量分别比博尚牌饲料少用48.34％、58.50％、48.81％和49.5％，但其育苗效果明显好于后者。80％欧开牌微胶囊和20％卤虫配合使用培育凡纳对虾幼体的效果比单独使用欧开牌微胶囊饲料培育效果好：前者的出苗率，出苗时平均尾重，平均体长分别高出后者38.73％、利用截欢囊句料培育凡姑对炸幼体苟比软研究25%和7.8%，各项出苗指标也明显高于后者(P 。05)。

The nursery water was the best, when microencapsulated diets of "OK" and rotifera were blended at the percentage of 80% and 20%, the nursery water quality was the best during the rearing period, the highest concentration of NH3-Nt (NH3-Nm) was 1.025mg/L (0.0836mg/L),and the highest concentration of NO2-- N was 0.0236mg/L. When larvae emerged, the concentration of COD was 1.526mg/L, Puyrrop Hta was 1000 Entries/ml, and the metamorphic rates of all periods exceeded symmetrically 97%, and the survival rates also higher than the control group fed pure crude diets. The emergence status in P7 period was described as follows: the metamorphic rate: 73.33%; the average tail weight: 2mg; average body length: about 7.604mm; which were 18.30%, 19.3%, 8.4% higher than that of control group respectively.

其中80％欧开牌微胶囊饲料和20％卤虫配合使用的育苗效果最好，在整个育苗期间该实验组水质较好，NH_3-N_t(NH_3-Nm)含量最高为1.025mg／L(0.0836mg／L)，NO_2~--N_2含量最高为0.0236mg／L，出苗时COD为1.526mg／L，甲藻类含量为1000个／ml，幼体各期的变态率较稳定均衡，均大于97％，成活率也高于只投喂天然饵料的对照组，至仔虾第7天(P_7)出苗时，出苗率为73.33％，平均尾重为2mg，平均体长达7.604mm，分别比天然饵料的对照组高出18.30％、19.3％和8.4％，各项出苗指标均明显高于对照组(P＜0.05)；且虾苗活泼健壮、体表洁净、均匀度高。
