建立了用凝胶渗透色谱净化-液相色谱-串联质谱分析烟草中3种抑芽剂残留的方法。卷烟中的待测抑芽剂组分用V∶V=1∶1超声提取后通过凝胶渗透色谱净化；凝胶色谱柱为Biobeads S-X3玻璃柱(50 g，400 mm×25 mm)，流动相为V∶V=1∶1溶液，流速5 mL/min；收集第10~25 min流出的液体用液相色谱色谱-三重四极杆串联质谱仪测定。

Lauric acid monoglyceride are present in some natural plant compounds, after extraction often as fungicides and anti-inflammatory agent is added to food, daily necessities, or in cosmetics.

月桂酸单甘油酯是天然存在于一些植物中的化合物，提取之后经常作为杀菌剂及消炎剂添加到食品、日用品或化妆品中。

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。

The restraining efficiencies of these amendments for Artemisia seleirgensis to absorb Cd are in the descending order of silican fertilizer, calcium magnesium phosphate fertilizer, lime, bone char, blast furnace slag and steel slag.

形态提取分析表明，施用固定剂处理使土壤Cd的水溶态、可交换态和碳酸盐结合态减少，而有机结合态和残渣态增加，说明促进Cd从有效态向缓效／迟效态转化是固定剂抑制芦蒿吸收Cd的重要机制。

To find the best method, different kinds of phenolic adsorbents and inhibtors have been used in the extraction and purification process.

在提取和纯化中，用加入不同的酚吸收剂和抑制剂并比较酶活性的高低来确认最佳方法。
