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。

First, having experienced World War twice and a variety of economic and political crisis , making participators and witnesses have to reconsider human being' behavior profoundly; Second, the easygoing life people have lived since the beginning of history which follows the established, national, graded and familial tradition outmoded conventions collapsed with the prompt development of modern science and technology, which makes human being reconsider their own way of subsistence and nature again; Thirdly, at the end of the 19th century and the beginning of 20th centuries, the school of materialism, empiricism, the side of naturalism and the side of idealism, apriorism, and spiritualism all realized they have ignored the research on human being's self, thereby the contradictions of different understanding of human being become extraordinarily obvious and pungent
第一,人类历经了两次世界大战和种种经济、政治危机,这使参与者和目击者不得不反思人类的这些行为;第二,人们自有史以来的那种不慌不忙的,按既定的、民族的、等级的、家族的传统陈规所进行的生活,随着现代科学技术的迅猛发展而迅速互解,这不能不使人类重新审视自己的生存方式和本性;第三,在19世纪末20世纪初,唯物主义、经验主义、自然主义一方与唯心主义、先验论、唯灵论一方都意识到自己忽视了对人类自身的研究,从而对人的理解的对立变得异常突出和尖锐起来

In this paper, after taking over coupling effect between electronic spin and orbital angular momentum, to revise the formula of electronic angular momentum in Bohr's theory, and electronic speed formula is obtained in a single-electron system, and to correct the energy level formula of atomic orbit in Schr? dinger's method by relativistic effect, the theoretical improving formula is built for spectrum fine splitting calculation, the calculated values are in good agreement with experimental ones, and reflect changing law of spectrum fine splitting values.
本文在考虑了电子的自旋角动量与轨道角动量的耦合作用后,通过对Bohr理论中的电子运动角动量的修改,推导出单电子体系的电子速度公式,结合对Schrdinger的原子轨道能级表达式相对论效应修正,从而得出本文的氢及类氢离子光谱精细结构值的理论计算公式,应用此改进公式,所得的计算值与实验观测值符合得很好,计算结果也反映了氢及类氢离子光谱精细结构数据变化的规律性。
