Virus hasn't cell construction. A lot of simple virus is only made of nucleus acid and protein tegument, so we can regard it as nucleoprotein. A type of virus pill usual has a kind of nucleus acid. After virus infect sensitive host cell, the nucleus acid of virus will enter cell and produce its descendant and new protein by reproduction and expression. Then, the new synthetic virus is made up of descendant that release form cell by regular way. This specific way of reproduction of virus called reproduction.

病毒不具有细胞结构，一些简单的病毒又由核酸和蛋白质构成，故可把它们视为核酸蛋白分子，一种病毒的毒粒内通常只含有一种核酸，病毒感染敏感宿主细胞后，病毒核酸进入细胞，通过其复制与表达产生子代病毒基因组和新的蛋白质，然后由这些新合成的病毒组分装配成子代毒粒，并以一定的方式释放到细胞外，病毒的这种特殊繁殖方式称为复制。

(1) In the sorption kinetics experiment, Cu2+ sorptions by Ceratophyllum demersum, Myriophyllum triphyllum and Hydrilla verticillata respectively, all reached balance within 35mins, all of the test results of sorption kinetics recommended the pseudo second-order equation and indicated that this kind of sorption was a complicated process of simultaneous actions of many reactions. The test results of thermodynamic sorption fitted with Langmuir model better than Freundlich model, and the maximum sorption quantites were 13.12, 20.12, 7.79mg/g, respectively,In the desorption test, the desorption rates of each plants were all below 1%, indicating strong sorption-holding action of these submersed mcrophytes on Cu2+.

通过上述研究，得到以下结论： 1、狐尾藻、金鱼藻、黑藻在对铜离子的吸附动力学实验中，均在35min内达到吸附平衡，分别用一级动力学方程和伪二级动力学方程拟合，结果均为用伪二级动力学方程拟合效果较好，表明该吸附为多种反应同时作用的复杂过程；在热力学实验中，三种植物的吸附曲线都能较好的用Langmuir曲线拟合，其拟合最大吸附量分别为13.12、20.12、7.79 mg/g；在解吸实验中，三种植物的解吸率都较低，说明对铜离子都有较好的吸持能力。
