1·The thesis exploited the dynamic system of monitoring the water of bed plate and apical plate applying the technique of high density electrical resistivity.

本论文创造性地应用高密度电阻率技术，开发出了采场底板破坏及底板水动态监测系统。

2·For high formwork support system, different apical extension length (a) and laying drawing pace have obvious influence on the whole stable bearing capacity.

对于高支模体系，不同顶端伸出长度(a值)和搭设步距对其整体稳定承载力有显著影响。

3·In comparison with embryogenesis, it is easy to get plantlets from shoot apical meristems, and it is suitable and convenience to be used as transformation system.

与棉花体细胞胚胎再生途径相比，棉花茎尖分生组织培养植株成苗的时间短，培养方法简单，也不受基因型的限制，适合作为基因转化的受体系统。
