RATIONAL DETERMINATION OF TNE BEAM AND COLUMN CROSS-SECTIONAL SIZES OF THE FRAME STRUCTURE IN A EARTHQUAKE ZONE

At the preliminary design stage of a building, it is neccssary to determine thebeam and column cross-sectional sizes of frame strtictures.According to some provisions of the"Building Aseismatic Design Code"(GBJ 11-89),main factors having influence on the beam andcolumn cross-sectional sizes are analyzed.and calculating formulas for the determination of the beam and column cross-sectional sizes which are satisfied the restrained condition of horizontal dis-placement of a building are derived in this paper.     

天津地区十字花科蔬菜病毒类型及其消长规律的研究

本文论述了天津地区十字花科蔬菜的病毒类型.主要分为四个类型:第一类芜菁花叶病毒(TuMV),第二类烟草花叶病毒(TMV),第三类黄瓜花叶病毒(CMV),第四类称为甘兰僵矮病毒,其中以芜菁花叶病毒为主导类型.调查鉴定结果表明,本地区夏季十字花科蔬菜病毒,主要来自种株白菜.二秋小白菜,小油菜以及秋甘兰,秋萝卜可为秋季大白菜直接提供毒源和传播介体.夏季栽培的或野生的十字花科植物是秋白菜病毒病的桥梁寄主.根据病毒消长规律的研究结果提出了秋白菜病毒病的防治途径.     

川渝地区偏高水分稻谷和小麦实仓安全储藏预警技术研究

研究了川渝主要储粮区(中温高湿区)偏高水分稻谷和小麦的实仓安全储藏预警技术。实仓试验结果表明,在常规储粮条件下,稻谷和小麦中早期储藏危害真菌的生长均明显受到水分、初始带菌量和温度等因素的影响,小麦的耐藏性和储藏安全性明显优于稻谷。早期储藏危害真菌的数量变化可以作为监控即时粮情的重要参考指标,其良好的预警作用(高灵敏性和及时性)对粮食安全储藏具有十分重要的意义。     

畜禽全、半同胞有规律系谱迭代法计算近交系数的研究与应用

在实践中研究出用迭代法计算有规律系谱畜禽的近交系数.在满足使用条件下,此法不必查找通径回路数,即可用计算机迅速、准确地算出多世代育种个体的近交系数.已实际应用于蛋鸡育种的数值计算中.比用人工查找通径法计算近交系数提高工效60倍以上.获得良好结果.因方法简便也适合于手算,有实用价值.但本迭代公式并非通用近交系数计算公式,有使用条件.这是其局限性.有待于进一步研究发展.     

冬小麦优质高产育种的几个生理参数的初步探讨

1983～1985年3年田间试验(中高肥水平,包括33个冬小麦品种)研究了粒秆比(G/LC)、氮粒杆比(NG/NLC)、茎叶重(WLC)和茎叶氮(NLC)四个性状对籽粒产量、蛋白质含量和蛋白质产量的影响。通过方差、相关和逐步回归等分析说明四个性状品种间差异显著;四个性状均与产量和蛋白质产量显著和极显著正相关;G/LC 与籽粒蛋白质含量显著负相
