Based on experimental results, a reaction mechanism of oxidation leaching of Ag in ammoniacal solutions was discussed.

文中讨论了在氨性溶液中Ag氧化浸取的反应机理。

Experimental conditions that a great deal of copper matrices were separated as well as trace Se and Te were concentrated in ammoniacal solutions by co-precipitation separation were studied.

研究了采用共沉淀分离手段在氨性条件下分离大量铜基体并富集痕量硒、碲杂质的实验条件。

In this study, therefore, the effects of 5-HT and NA on Gly response were investigated in rat sacral dorsal commissural nucleus neurons.

因此，5-HT和NA可能通过细胞内第二信使通路磷酸化Gly受体通道，增强氯离子电流，从而增强抑制性的甘氨酸能传递。

Together with the cited sequences of other species (cattle, zebu cattle and buffalo), the molecular phylogenetic tree was therefore built to probe phylogenetic relationship between Bovine subfamilies, Total 5 variation sites were examined and two types of mutation, transition and transversion, were observed, with the overage percentage of nucleotide variation of 1.66%. It demonstrated the poverty of polymorphism at exon 5 of GH gene of three bovine species. There was only one missense mutation out of 5 mutation sites which led to the shift between leu and val amino.

结果表明，在雷琼牛、巴州牦牛和巴州蒙古牛中共检测到5个变异位点，核苷酸取代方式仅有转换和颠换，核苷酸平均突变率仅为1.66%，说明这3个牛种GH基因外显子5多态性较为贫乏；5个变异位点中仅有1个为错义突变，导致亮氨酸和缬氨酸的转换，但该突变在牛种中分布有差异。

Devise a pair of primer to put out the section of pgE which code the dense antigen episode, clone into pET-32a, name the masculine plasmid with pET-32pgE. Transform the BL21 strain with pET-32pgE, choose several single bacterium drops at random and contaminate 2X YT. vibrate at 37癈 over night. Contaminate another tube with the above culture to the final concentration of 2%, continue to culture to OD6oo0.6, add IPTG to the final concentration of Immol/L. inducing 6 hours. Analyse the expression with SDS-PAGE and Western-blot, the result is that the expression has actually happened and the product has immunoreactivity.

设计一对引物从gE全基因克隆载体pgE中调出抗原决定簇密集编码区，克隆进PET-32a表达载体，双酶切和PCR鉴定出阳性者，命名为PET-32pgE，转化BL21菌株，挑取单菌落在加有氨苄的2×YT培养基中37℃过夜长至饱和，按2％体积转种另一管，培养至OD_(600)为0.6，加IPTG至终浓度1mmol／l，诱导4～6小时，SDS-PAGE和Westernblot分析，证明确实表达并具有免疫反应性。
