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.

The microspore was more like a tetrahedron, whilethe polar was more like a triangle. The number of microspore in every anther wasbetween 2600～3600, so the amount of pollen was quite large that it was propitiousto spread and pollination. P/O was 8088 and the breed system was singleheterosexual copulatoryb. The viability of pollen was normally above 50%. The testof pollen culture showed that the viability of pollen was up to the tiptop under thehigher temperature and lower humidity (38℃,40%),while it was weakest under thelower temperature and lower humidity (16℃,40%).The OCI is 4, and the breedsystem was belong to autocopulation. If it was heterosexual copulatory, there must beintermediums for pollination. It was recorded there were more than 40 species ofinsects on the anthotaxy or followers of Malania Oleifera. Under different weather,different living environments and different plants the frequency and rush hour of theinsects to visit the followers were different. Actions of different kinds of insect werealso different. According to the results of the observation, the form of fluid and seedof Malania Oleifera mostly rely on the action of insect pollination, especially thebees.

蒜头果的花序为聚伞形花序，有小花8～10朵，小花较小；按花粉大小等级划分，蒜头果的花粉粒属于小的范围；花粉粒呈近四面体，极面为近三角形：每粒花药所含的花粉粒在2600～3600粒之间，花粉量较大，有利于花粉的传播和授粉；胚珠比值为8088，繁育系统为专性异交类型；花粉生活力一般在50％以上；在不同温度湿度条件下测得蒜头果花粉的生活力在高温低湿(38℃，40％)的条件下最高，在低温低湿(16℃，40％)的条件下最低；杂交指数值为4，繁育系统自交亲和，异交，需要传粉者；记录到的访花昆虫有40余种，访花昆虫的访花频率及高峰时间不同，不同种类的昆虫的访花行为也是各有所异；从观察的结果看，蒜头果的种实的形成大多数依赖于传粉昆虫的活动，其中主要是蜂类。
