Two inducible and extracellular chitosanases secreted by Penicillium sp. D-l were purified by ammonium sulfate precipitation as well as gel filtration. The purified enzymes of ChoA and ChoB had molecular masses of 93 and 21 kDa by SDS-PAGE. Both ChoA and ChoB have an acidic pH optimum, which were 4.0. The enzymes were stable over the pH range 3 to 5 for 1 h.

Under coaction of endogenic geological processes and water and heat conditions, the drainage development, and water formation and transformation in the inland watershed. were indicated hydrological characteristics of periglacial zone. The hydrological process is mainly related with to changes in mountain areas. It by 41% of precipitation in mountain areas as surface discharge flows into middle and lower reaches, which makes up a main physical basis of the quantitative and qualitative relationship for various functional units in the eco-system in mountain front plain.

对影响混凝沉淀效果最大的水流因素—平流沉淀池中异重流的形成原因进行了讨论，对其流场进行了分析，并对不同方案混凝沉淀效果进行了比较，同时，就减弱异重流的条件进行了讨论。

The accumulation rates of terrigenous long-chain compounds peaked at H3, paralleling those of the algae biomarkers, demonstrate that the enhancement of Eustigmatophceae and coccolithophorid productivity at H3 is caused by an increased terrigenous nutrient supply from the Sunda Shelf. This interpretation coincides with Sunda Shelf laid bare, the low sea level and river flood due to the abundant monsoon precipitation in southern South China Sea in the last glacial.

同时这些化合物的堆积速率在H3都出现了极大值，与水生生物来源的生物标志物的变化一致，反映出在南海海平面降低，巽它陆架出露背景下这一时期丰富的季风降雨导致河流洪水泛滥，从而引起南沙海区输入的陆源营养元素增多，黄绿藻、颗石藻海洋表层生产力的增高。

The new preparation method of catalyst soak precipitation method is originated Used of new surfactant APG as a assistants, mixed salt soak sotution and coprecipitant with low surface tension and strong permeate and weted force coprecipitate active composition to the inner micropore of prepreparated supporter with hight mechanical strength and large pore diameter This method solve the problem of the low mechaniceal strength of coprecipitated catalyst.
