蚕丝脱胶方法的比较分析

对高温高压水、尿素溶液和碳酸钠溶液煮沸的蚕丝脱胶方法作了比较研究。结果表明 ,蚕丝在高温高压条件下丝胶蛋白易于溶解 ,脱胶率达 80 %以上 ,获得的丝胶分子量大 (10～ 2 0 0kD) ;在碱性的碳酸钠溶液中煮沸脱胶 ,丝胶蛋白易于降解或水解 ,其回收的丝胶分子量 2 0kD以下。蚕丝在高温高压水或高温高压尿素溶液中的脱胶率都随着处理温度和压力的增大而提高 ,而回收的丝胶蛋白分子量随着处理温度和压力的增大而下降。高温高压水蚕丝脱胶法是一种高效率、低成本、无污染的脱胶方法 ,特别适用于绢纺厂、丝棉厂等蚕丝的脱胶与加工以及纺织厂生丝的精练等。

对传统的异烟酸－吡唑啉酮比色法测定CN^-的条件进行了优化，并用于测定杂交苏丹草体内CN^-的含量。结果表明，苏丹草在苗期体内CN^-含量较高，达163mg/kg，以后呈逐渐下降的趋势。     

Integration of transgenes into sexual polyploidization schemes for potato (Solanum tuberosum L.)

Most potato transgenic research has focused on development of resistance to pathogens and modification of potato physiology. Many transgenes, particularly those conferring pathogen resistance, could substantially lower potato production costs in developing countries. However, transgenes have not been reported in sexually propagated 4x-2x potato hybrids commonly grown in developing countries. Two transgenes,the Bacillus thuringiensis cry3Aa endotoxin protein gene and the PVY°coat protein gene, were engineered intodiploid and tetraploid potato using Agrobacterium tumefaciens-mediated transformation. Cry3Aa was produced at high levels in several lines while the PVY° coat protein was not expressed. Diplandroid and tetraploid genotypes were crossed to produce transgenic 4x-2x hybrids. Genetic transformation had no discernable effect on fertility ofthe primary transformants, germination of4x-2x seed derived from the transformants and agronomic performance(tuber set, average tuber weight and total tuber yield) of the 4x-2xhybrids. The transgenic 4x-2xhybrids produced non-viable pollen and could only be crossed as female parents. Results suggest that transgenes, such ascry3Aa, could be expressed in 4x-2x hybrids to lower costs of production with no significant effect on plant phenotype. This revised version was published online in July 2006 with corrections to the Cover Date.     

STATIC ANALYSIS OF THE BODY OF MAN''S DRY GAS HOLDER WITH A VOLUME OF 120000m~3

This paper presents finite element calculations of the body of MAN'S dry gas holders with a volume of 120000m~3 under internal pressure and wind load. The analyses of displacements and internal forces of the body are presented. The control points of strength and rigidity check are determined. The work in this paper is very valuable to body's design.
