利用假想平面法建立了室式辐射管搪烧炉传热数学模型，并进行了仿真计算，结果表明，假想平面法能够大大简化室式辐射管搪烧炉内大量的角系数的计算，并可对炉子的有关参数(如辐射管的距径比、布置、炉墙结构等)进行优化计算。

To study the cytopathogenic effect of mycoplasma membrane.the pro- toplasmic membrane of the mycoplasma causing swine enzootic pneumo- nia was prepared by the repeated Freeze-thaw method or the osmotic shock method,and was then inoculated into the rabbit kidney primary tissue cultures for examining their biological activities.The experimental results were as follows:in the cultures inoculated with 25～50μg of membrane protein ,the cytopathogenic effect was considerable.in the cul- tures inoculated with ...

用低渗解体及反复冻融裂解的方法，制备了猪喘气病病原霉形体膜，将所制备的膜制品接种兔肾原代单层细胞，作生物学活性观察，在接种量按蛋白含量计算为25～50微克膜蛋白的细胞管中观察致细胞病变作用，在接种17.5微克膜蛋白的细胞管中作用不明显，接种6微克膜蛋白的细胞管无致细胞病变作用。
