Abstract:The paper is a review of the advance of fusion of bacterial protoplasts. A part of author's work is also presented. A detailed discussion has been given on the fundamental procedures in protoplast fusion, including selection of initial strains, preparatio

Abstract:Rhodopsudomonas NA 08609固定在琼脂中,当固定化琼脂浓度为1.5～2.0%,初始菌体密度为3.0mg蛋白质/g凝胶时对产氢是适宜的。产氢培养基“gB”不需抽真空,在30℃时固定化细胞的产氢速度比悬浮液快,效率比悬浮液高,但是在40℃时则相反。Rhodopsudomonas NA 08609固定在琼脂,角叉菜聚糖胶、海藻酸钙中,角叉菜聚糖胶固定化生长细胞比琼脂固定化生长细胞及海藻酸固定化细胞凝胶株的产氢效率高,(71.8%)但是海藻酸钙固定化细胞凝胶株在产氢速度方面较高。(285ul/cm~2/h)

Abstract:THis paper introduced Type CS-2 Temperature Informations processor developed by authors. The processor operates upon a specially designed microcomputer system and correspending softwares and precise analog eircuitry. This processer is equipped with a new

Abstract:Equivalent length of warp yarn in weaving loom was analysed. The geometric length and equivalent length of warp yarn which is setting in loom whether revolving or fixed back-rest in the weaving machine mode 1511 were calculated and contrasted. the article

Abstract:THis paper describes thedesigning strategy and basic measuring principle of the "Microcomputer Controlled Electric Fan Motor Performance Measurement Line". It contains system design, interface, application software programming and the design of the transd

Abstract:A finite element program designed for the stress analysis of ribbed shells is presented. In this paper, the stiffness matrices and load vectors of the beam elements have been transformed so as to get the nodal displacements of each beam element compatible

Abstract:The transfer matrix formula is derived from the element stiffness and mass matrices of plane beam in the finite element method. It is just the same as the general formula derived by the material mechanics and mechanical vibration. Thus, the equivalence of

Abstract:The paper shows the principle and design method of combined mechanism of fixed cam and likage, and the influence of the parameters, the support point of swing linkage and with the driving form on the pressure angle discussed. Therefore, a reliable method
