另外 ，在 0 。6MPaNaCl下，随处理时间延长，盐地碱蓬和琐琐种子的α淀粉酶活性不断提高，SOD活性基本不变，但小麦和大麦种子的α淀粉酶活性在处理 8d后接近最大值，SOD活性显著下降。

During hydrolysis, when both the mesothermal-α-amylase and fungal-α-amylase were used, the transformation ratio of the buckwheat starch hydrolysis surpassed 99.5%. It also could get a higher ratio when two kinds of enzymes mixed with different proportion.

在荞麦淀粉的水解过程中，中温α-淀粉酶与真菌α-淀粉酶对荞麦淀粉的水解转化率均超过99.5%，两种酶按不同比例混合使用对淀粉的水解转化率更高。

Its activity was specific and was affected by pH, reaching the peak in weak acidic condition. It obviously inhibits amylases from D. melanogaster, Solenopsis invicta, Odontotermes formosanus, Periplaneta Americana Linnaeus, and Alphitobius sp. In addiction, the study points out Phaseolus vulgaris, Phaseolus coccineus L. and Glycine max, which have significant inhibition toward pancreatic amylase.

经测试发现此抑制剂在85℃时仍具备抑制果蝇淀粉酶之活性，为一热安定性蛋白质，其抑制作用受pH 值影响很大，在偏酸性环境下的效果最好，且其抑制作用具特性，可明显抑制果蝇、入侵红火蚁、白蚁、蟑螂及面包虫等昆虫的淀粉酶活性。

The protease activity in foregut was higher than that of midgut in an acidic condition at pH 5.0-5.8, while in an alkalescence condition at pH 7.0-8.6, the protease activity was higher in midgut than that in foregut. The lipase activity of foregut was high and stable in two pH ranges: 4.2-5.0 and 6.2-7.0, and that of midgut was high at pH 3.8, while the lipase lost enzyme activity at pH over 9.0. The amylase activity was high and stable at pH 6.6-7.4 in both foregut and midgut. The cellulase activity of foregut and midgut was high and stable at pH 6.2-7.4 and 5.4-7.0 respectively.

刺参前肠蛋白酶活力在酸性环境下较中肠高，且在反应pH为5.0-5.8之间酶活力相对稳定，而中肠蛋白酶活力在碱性环境下较前肠高，且在反应pH为7.0-8.6之间酶活力相对稳定；刺参前肠脂肪酶活力随着pH的升高出现两个相对稳定的峰值，分别为4.2-5.0和6.2-7.0区间，中肠脂肪酶活力在pH为3.8时达到最大值，而在pH超过9.0明显失活；刺参前肠和中肠淀粉酶活力在pH变化时表现出相似的变化趋势，在反应pH为6.6-7.4之间酶活力较高且相对稳定；刺参前肠和中肠中纤维素酶活力在pH变化时反应不一致，前肠淀粉酶在反应pH为6.2-7.4之间酶活力较高且相对稳定，中肠纤维素酶活力在反应pH为5.4-7.0之间酶活力较高且相对稳定。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
