The glucoamylase I gene was inserted into the pAC1 plasmid,and a expression plasmid was constructed,then it was used to transform the yeast strain, S.cerevisiae AS2.1364,without auxtrophic marker,The amylolytic tests showed that when this transformant was incubated on plate of YPDS medium containing 1% glucose and 1% starch at 30℃ for 48 hrs zones of starch degradation could be visualized by stained with iodine vapour.

这说明酵母转化子不仅表达了该酶，且有效地分泌到胞外，从而水解培养基中的淀粉，进一步测定酵母转化子48hrs发酵液的葡萄糖淀粉酶活力为8.4u/ml，培养基中的淀粉已完全水解，其生物产量较高。

The results show that the originated materials for electrolyte aluminium is Al2O3 and AlF3 has good property to absorb vapour. After the water contained in the originated materials goes into electrolyte, AlF3 reacts with water hydrolyzed and the rest of water is electrolyzed into hydrogen and oxygen. Hydrogen enteres aluminum liquid by diffusing and autoecious in Al2O3, which is the main source of hydrogen in electrolyte aluminum liquid.

研究结果表明：电解铝所用的原材料(Al2O3和AlF3等)有良好的吸水性能，所携带的水分进入电解液后，或与氟化盐发生水解反应，或被电解成氢和氧，析出的氢通过扩散和Al2O3寄生机制进入铝液，这是电解铝液中氢的主要来源。

A method for eliminating the internal oxide structure in the gas-phase carbon-nitrogen osmosis of gear features that the CCL4 is added to the kensene as carburizer and then is decomposed to generate Cl2 for reducing the oxide, the ammonia gas as nitrizing agen passes through the cylinder of silica gel or granular calcium chloride for adsorbing residual water vapour and then through the cylinder of 5A molecular sieve for adsorbing residual O2, and the resistance wire is wound on igniting pipe at furnace top to prevent the NH4Cl in exhausted gas from being condensed.

本方法采用在气体渗碳剂煤油中，加入6～8％的CCl 4 ，使共渗炉内的CCl 4 分解出新生的Cl 2 ，使已形成的合金元素内氧化物还原；在渗碳剂氨气入共渗炉前，先经过硅胶瓶或桶及粒状氯化钙瓶或桶过滤，吸附掉氨气中的残留水蒸汽，再经过5A分子筛瓶或桶吸附掉氨气中的残留氧；在靠近炉顶位置的点火管周围缠绕带瓷环的电阻丝，靠电阻丝的副带加热，使排气中的NH 4 Cl不冷凝结块等措施实现内氧化组织的消除。
