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。

在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的"小白斑"病毒的复合病。小白斑病毒在20多种寄主上,包括十字花科,单独汁液接种时只能产生局部坏死病斑,不能系统侵染;单独接种而能系统感染的寄主有百日菊,只产生极轻微的深浅绿花叶,甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。

Firstly, the two parts are solved separately, and the results are then coupled together. Because the thickness of the combustion reaction zone at high Re and Da numbers is less than the turbulent diffusion scale in diesel engines, the flame is extremely thin, its micro-structure keeps the laminar structure, so the turbulent flame can be regard as the ensemble of locally one dimensional, thin laminar flamelet embedded within the turbulent flow field.
由于柴油机中在高雷诺数和高Damkoeler数的情况下,燃烧反应区厚度小于湍流耗散尺度,火焰极薄,其微元保持层流结构,因此,湍流火焰可视为嵌入湍流流场内局部具有一维结构的薄的层流小火焰的系综,这便构成了层流小火焰模型主导思想,同时也使层流小火焰模型模拟柴油机湍流燃烧过程成为可能。

In PsNPV infected treatment, the color of the gland was purple-black dyed with eosin and the cells were distortedly squeezed together. The tracheae nearby showed grievous pathological changes and a lot of white granules deposited around it. The pathological changes in PsGV infected treatment showed another pattern. The gland body was relative small with smaller individual cells, most of which were red dyed with eosin. The cell limits were obscure.In coinfected treatment,there were few gland cells colorated by esoin.
结果表明,不同感染组粘虫前胸腺腺体都有不同程度的组织病变,PsNPV感染组在感染晚期与前胸腺相连的气管严重病变,出现大量白色颗粒状物累积,被伊红染成紫黑色,腺体细胞被挤压变形;PsGV感染组的前胸腺腺体变小,单个细胞也小,细胞界限不十分明显;两种病毒混合感染组的腺体细胞小,能被伊红染色的细胞极少。

The feeble fingers were never idle,and one of her pleasures was to make little things for the school children daily passing to and fro, to drop a pair of mittens from her window for a pair of purple hands, a needlebook for some small mother of many dolls, penwipers for young penmen toiling through forests of pothooks, scrapbooks for picture-loving eyes, and all manner of pleasant devices,till the reluctant climbers of the ladder of learning found their way strewn with flower, as it were, and came to regard the gentle giver as a sort of fairy godmother, who sat above there, and showered down gifts miraculously suited to their tastes and needs.
她那虚弱的手指从未有闲着,她的乐事之一便是为每天从屋旁经过的学童们制作小东西--在窗口放一双手套,这是为冻紫的手准备的;放个针线包,给某位拥有许多玩具娃娃的小母亲;放一些拭笔布,给那些在歪七竖八的笔划丛林里辛勤劳作的小书法家们;放一些剪贴薄,给那些喜欢画画的孩子们;还有各种各样令人愉快的小玩意,直到那些极不情愿攀登学问阶梯的孩子们发现,他们前进的道路上布满了鲜花。这时他们把那亲切的馈赠者看作是童话中的仙女。她坐在那上边的屋子里,给他们抛投各种奇迹般契合他们品味和需要的礼物。
