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。

The analysis methods for the determination of micro or trace elements in high moisture jellyfish were developed. The fatty acid compositions in difderent parts of fresh jellyfish were determined by GC/MS method. Thirty-five fatty acids were identified, and most of them were found in R. esculentum jellyfish for the first time. Especially, two unusual very long chain polyunsaturated fatty acids that were never detected in the other jellyfish also were determined. Amino acids were abundant in R. esculentum jellyfish, especially containing sulfur amino acids, and could be supplied for human diet. The polysaccharide in umbrella part of jellyfish was composed of glucose, galactose and uronic acid, and its molecular weight was 40,000, but the polysaccharide of the oral arms part consisted of glucose, mannose and glycuronic acid, and its molecular weight was 43,000. Above-mentioned data were never reported. The ethanolic extract of oral arms part of jellyfish were extracted by different polar solvents (petroleum ether, acetic ether, n-butanol), and antibacterial activity was tested to these extracts by four species of terricolous pathogenic bacilli and three species of botanic pathogenic fungi. The result demonstrated that the petroleum ether extract had certain bactericidal activity for two species of pathogenic bacilli, and n-butanol extract had certain inhibited activity on apple rot pathogenic fungus.
