E. , plastic deformation developed into a critical state, local stress in dislocation-freezone will be equal to atomic bond strength, which will induce the initiation of SCC microcrack.

为了说明这个附加拉应力在阳极溶解型SCC中的主要作用，对不同含H〓O量的甲醇溶液，用慢拉伸法测量了SCC敏感性，同时测量了自然腐蚀时表层拉应力的大小。

The number of atomic and sub-surface oxygen species may decrease with the addition of iodine.

碘的加入可使原子氧和次表层氧物种种类更单一，更有利于甲醇的氧化脱氢反应。

To study the expression, purification and bioactivity of human augmenter of liver regeneration in Pichia Pastoris, the expression plasmid pPICZαA- ALR was constructed and transformed into P. Pastoris by the method of electroporation transformation. Induced with 0.5% methanol, the 30 kD protein in the culture supernatant of recombinant P. Pastoris was confirmed to be rhALR by SDS-PAGE and Western blot. Quantitative analysis showed that the target protein was in a level of 66% of the total protein of the culture supernatant, with a yield of 40mg/L.we had performed DEAE anion exchange chromatography two times with excessive and regular adsorption quantity consecutively, and then the rhALR above 95% purity and 52% protein recovery could be obtained by G75 molecular sieve chromatography at last step. The bioactivity assay of the purified product showed that rhALR could stimulate the proliferation of HepG2, SMMC-7721 and NIH-3T3 in vitro.

为在毕赤酵母中分泌表达人肝再生增强因子，以色谱法分离纯化后进行体外活性研究，构建表达载体pPICZαA- ALR，经电穿孔转入毕赤酵母中，用0.5％甲醇诱导表达；重组酵母培养上清经SDS-PAGE电泳和western blot鉴定后表明， rhALR以分子量为30kD的二聚体为主；定量分析结果表明，重组酵母培养上清中rhALR约占总蛋白的66％，表达量约为40mg/L；经DEAE柱和G75柱纯化后，获得的rhALR纯度大于95％，得率为52％；体外生物学活性实验表明，rhALR能明显促进HepG2、SMMC-7721和NIH-3T3细胞的增殖。

Aureomycin on reduction with zinc-acetic acid gives desdimethylaminoaureomycin under mild conditions and desdimethylaminodesoxyaureomycin under more drastic conditions.

金霉素在冰醋酸与甲醇溶液中，用锌粉氢解，在温和条件下，产生脱二甲胺金霉素；较剧烈条件下，则生成脱二甲胺脱羟金霉素。
