However,the number of events and frequency of copulation between the biotype B and ZHJ2 decreased significantly compared with those between females and males of a given biotype being placed in one arena, demonstrating a degree of pre-mating partial reproductive isolation between these two biotypes.Although some of the adults of the biotype B and ZHJ2 copulated with each other,mated females produced only male progeny,demonstrating a post-mating complete isolation in reproduction between the two biotypes in cases where copulation has happened.

4B型烟粉虱与ZHJ2型烟粉虱在棉花上的竞争取代过程当B型烟粉虱与ZHJ2型烟粉虱以3：20的比例在棉花上开始竞争，在未喷施吡虫啉乳油的情况下，B型经过6代完全取代了ZHJ2型，并伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；在喷施吡虫啉乳油的情况下，B型取代速度加快，经过5代完全取代了ZHJ2型，也伴随着B型雌虫比例的上升和ZHJ2型雌虫比例的下降；B型单一种群中，雌虫比例稳定在55%～60%；ZHJ2型单一种群中，雌虫比例稳定在50%左右。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
