In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为:CuD与烯醇形成络合物:含氮有机物的引入起到稳定络合物,降低活化能的作用:而TMPO则充当携氧子起传递氧的作用,并具有选择氧化功能:这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中,用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A,本方法未见文献报道,使反应系统更加温和,收率由52%提高到88.6%:并解决了次氯酸钠稳定性差、有效氯含量低的实际问题,具有重要的实用意义。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物,从猪卵巢上获得的卵母细胞数量虽然较多,但成熟度比较低;由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内,跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应;如果卵胞质成熟或活化程度不够,加之圆形未成熟精细胞成熟度比较差等原因,很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足,引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等,使ROSI显微受精失败。

Because Fov also existed in the roots ofsymptomless seedlings and the stems of both symptomatic and symptomless seedlings afterinoculation,the induced SOD isozyne seems to be originated from plant,not Fov.

由于在接种但未显症的棉株根中和显症或不显症棉株的茎中均可高频率地分离到Fov,因而初步判断该诱导性SOD酶源于棉花基因组中的某一SOD酶基因被活化。

The peripheral blood mononuclear cells were aseptically isolated from goats not treated by selenium and cultured in vitro in media containing sodium selenite respectively at the levels of 4,8,12 and 16 μg/mL, and then their in vitro activation and IL-2 levels were tested.

无菌分离未服硒山羊PBMC,分别加入4,8,12和16μg/mL亚硒酸钠进行体外培养,检测硒在体外对PBMC的活化作用及其分泌IL-2的影响。

Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.

首先考察反应的热力学可能性;其次探讨反应机理;通过实验确定:①Ca主要以气态形式迁移到Dy〓O〓表面参与反应;②Dy〓O〓被Ca还原为Dy的速度很快;③Dy主要以气态形式迁移到Fe表面逐级生成Dy-Fe合金;④DyFe〓的形成过程可以应用收缩核模型来描述;⑤Dy通过DyFe〓产物层向缩小的未反应核中心Fe的扩散是反应的控速步骤,通过动力学计算确定:还原扩散反应的表观活化能E〓=45kJ/mol。

Results Human complement can be activated by unsensitized EL-4 cell through the first pathway.

结果 未致敏EL-4细胞可直接以Ca2+、Mg2+离子依赖的第一途径活化人血清补体系统,在细胞数为1×104~2×104时,1:200稀释的人血清补体为EL-4细胞的非致死剂量。

The results show that the differentheat treatment technologyhave noticeable effects on the activity ofhydrogen storage alloy,the stability capacity and cycle life ofhydrogen storage alloy were improved afterheat treatment,especially after 240 cycle times.

不同热处理工艺对合金的活化性能有较大的影响,合金经过热处理后,其稳定放电容量及循环寿命均有所提高,尤其是在240个周期循环后,热处理后的贮氢合金,其循环寿命明显高于未作热处理的合金。
