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。

In chapter 2, we define a new operator—the minimal operator on martingale space, it's well known that the maximal operator controls where given martingale f is large, intuitively, we say that the minimal operator controls where a martingale is small.
第二章引入了鞅空间上极小算子mf的概念,众所周知,极大算子可以控制一个"较大"的鞅,那么形象地说,极小算子就是用来控制那些"较小"的鞅,因此,在研究关于极小算子的加权不等式时,很自然地要估计诸如〓,log mf等算子的值。

Using nuclear DNA C-values for 539 angiosperms in China, we examined the variation of these values among growth forms and taxonomic groups and the relationship of these values with invasiveness. Mean DNA C-value of the 539 angiosperm species was 4.06 pg. Mean DNA C-value was(1) significantly lower for woody species (1.84 pg) than for herbaceous species(5.02 pg);(2) significantly lower for 360 dicots (2.20 pg) than for 179 monocots (7.80 pg);(3) significantly lower for annuals (2.78 pg) than for perennials(6.65 pg);(4) significantly lower for 134 weed species (1.93 pg) than for herbaceous non-weeds (6.75 pg) and for several families that have an unusually high proportion of weed species;(5) significantly lower for 47 exotic weed species (1.76 pg) than for 134 native weeds (1.93 pg), but significantly lower than that of "non-weedy" herbaceous species (6.75 pg);(6) lower for weeds than for "non-weedy" species in same genus or family; and (7) in herbaceous species, generally lower for weedy compared to "non-weedy" species, with some exceptions such as Avena fatua, whose DNA C-value is as high as 14.15 pg, contrarily, and some "non-weedy" herbaceous species in Cruciferae and Cucurbitaceae with very low values.

Secondly, the author has researched the wavelet coefficients distribution property based on the histgram of detail subimages, and proposed an adaptive image quantization algorithm according to local data distribution in every subimage. In this quantization procession, every subimage will be disparted to some sub-blocks, and the sub-blocks will be quantized with different quantizer according the coefficients distribution; when the bias is large, the sub-block will be quantized with high accuracy; when the bias is little, the sub-block will be quantized coarsely.
其次,作者通过对小波高频子带图像系数分布直方图的分析研究,根据高频子带图像中绝大多数系数的幅度很小、幅度大的系数出现的几率很小的特点,提出了一种基于子带图像局部数据分布特征的自适应量化算法:先把高频子带图像分成较小尺度子块,子块系数离散性越大,采用精度越高的量化器:子块系数分布越集中,使用精度较低的量化器。

通过模拟分析比较,揭示出了环件轧制过程中的金属流动规律:轧制时,环件外侧的变形最大,厚向中心部位变形最小,内侧的变形程度介于中间;环件内外环面的压应力分布和变化规律:在垂直于环件轴线的对称面上,压应力分布近似对称状态,而且在对称面上的应力最大,往端面方向开始减小;指出了环件轧制中轧辊与环件摩擦对环件成形的影响:对于环件的宽展变形,摩擦的影响很小,可以忽略;分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因,提出防止凹陷的措施:在轧制时,尽量使用快的进给速度有利于防止端面凹陷的产生;研究了导向辊位置对环件成形以及轧辊受力的影响:导向辊的位置对环件的宽展变形影响很小,但对轧辊的受力影响较大,当导向辊的中心位置位于毛坯初始中心位置之上时,驱动辊和芯辊的受力相对较小,这是导向辊导向时优先考虑的位置。
