This experiment with dilute alkali swelling on collagen extraction and separation, then purified by gel from collagen, and then glutaraldehyde, carbodiimide, has three types of di-isocyanate cross-linking agent on the plastic recombinant protein molecules cross-linked, the final test of infrared spectroscopy analysis of the results of their cross-linking to determine the extent of the effectiveness of cross-linking cross-linking agent to have an initial understanding.

本实验用稀碱溶胀法对胶原蛋白进行提取与分离，接下来用凝胶层析纯化所得胶原蛋白，然后用戊二醛、碳化二亚胺、己二异氰酸酯三种交联剂对胶原蛋白分子进行重组交联，最后通过对红外光谱测试结果的分析，对其交联程度进行判断，对交联剂的交联功效有一个初步的了解。，谢谢。

After enter to environment and occur complicated chemistry process, heavy metal may become many kinds of pollutions which be in different shape and different struction. For example, in soil, heavy metal can be differentiated five shapes generally, namely, dissolved, permutable by feeble permutoid, permutable by strong permutoid, original mineral, secondary mineral.

重金属排入环境后，有复杂的化学过程，形成多样化的形态或结构的污染物，如土壤中的重金属离子或类金属离子可分为五种形态：①水溶态的；②弱代换剂可代换的；③强代换剂提取的；④次生矿物中的；⑤原生矿物中的。
