Methods: To compare the method of the extract of RNA from goldfish using laminaranalysis column with that of using one-step guanidinium isothiocyanate-alcohol phenyl-chloroform.
方法：应用本层析柱方法从金鱼组织所提取RNA和采用异硫氰酸胍-酚-氯仿一步法提取RNA的比较。

Numerical analysis is made for the unsteady and steady, two-dimensional laminar natural convection in an enclosure caused simultaneously by the external heating and a local internal heat source.
Causes to the laminar defect of the umbrella bone steel occurring in the process of cold forming are analyzed by chemical analysis and microstructure analysis.
