在Kachanov提出的一维蠕变损伤演化方程的基础上，建立了同时考虑瞬时损伤和蠕变损伤的流变本构模型，理论值与试验值基本一致，验证了提出的蠕变损伤演化方程是正确的，所建的损伤流变模型能够较好地描述石膏角砾岩的加速蠕变阶段。

To examine the hypothesis, we test whether maize beta-amylase can serve as a lipase inhibitor.In order to conduct the interaction assay of beta-amylase and lipase, we adopted a preparative electrophoresis method with a Prep Cell to purify beta-amylase proteins from germinating maize endosperms and soybean cotyledons. We pre-mixed tested proteins with lipid substrate prior to the addition of lipase preparation and assayed the lipid hydrolytic activity.

本实验利用Prep Cell纯化玉米萌芽谷粒和大豆子叶中的beta-淀粉酶，分别将两种不同物种的beta-淀粉酶与胰脂解酶预先反应后，再加入脂解酶反应液中观察活性的变化，结果发现脂解酶的活性未如预期，没有抑制的效果产生，将甘薯beta-淀粉酶以同样方法与胰脂解酶作用，结果同上述两种beta淀粉酶依旧没有抑制的现象。
