Based on analysis for paleostructural characteristics of above four areas,the paper proposed that there developed a series of paleostructure belts under the background of regional uplifting in latest Mesozoic at the front of south Qilian Mt,and those paleostructures are characterized by NWNNWstriked anticlines and synclines,whose wavelengths are 15～20 km and middlescaled. At the same time,the paper also points out that most areas in western China are lack of upper Cretaceous,which implies the existence of a broad Late Cretaceous plateau in central Asia.

通过这4个地区古构造特征的研究，提出南祁连山前区中生代晚期在区域性隆升的背景下，形成了一系列古构造带，古构造活动的特点是形成北西-北北西走向的背斜和向斜构造，这些褶皱的波长为15～20 km，为中尺度规模。

Results The activity, recovery rate of activity and half-life of immobilized SOD were 333 U/g, 86.32% and 43.8 d respectively. After storage at room temperature for 5 d, the relative activity of SOD was still more than 80%. The optimal reaction temperature of immobilized SOD was 45℃, and the activity retentions after being used for the first and second times were 70.12% and 51.72% respectively. Both the optimal pH values for SOD before and after immobilization were 6, while the Km values were 0.16 and 0.18 mmol/L respectively.

结果 固定化超氧化物歧化酶活力为333U/g，酶活回收率为86.32%，半衰期为43.8d；固定化酶室温保存5d后，相对酶活力仍保持在80%以上，最适反应温度为45℃，使用一次后回收率为70.12%，重复使用两次后回收率为51.72%；固定化酶与溶液酶在pH6时活性最强，Km分别为0.18mmol/L和0.16mmol/L。
