The recombinant inbred line population derived from Xieqingzao B/Milyang 46 and its genetic linkage map were used to map the QTLs controlling cooked rice elongation in two environments, Hainan and Hangzhou.

利用协青早B/密阳46所构建的重组自交系群体及其相应分子遗传图谱,在海南和杭州两地试验,以延伸率作为米粒延伸性考察指标,检测QTL主效应、上位性效应和基因型×环境互作效应的遗传分析方法,进行联合检测分析。

The nano-material delay composition with higher burning precision and more stable delay time is produced by adding nano-material additives,the change in delay time of detonator is no more than 5% after one year under natural condition.

文章通过对延期药粒子结构模型的分析,找出了延期药燃烧不稳定和秒量飘移的原因,应用纳米添加剂研制了纳米延期药,其燃烧精度高,秒量稳定,雷管自然贮存1年后秒量变化不超过5%。
