Reduction of ovule number as a tendency of speciation in the genus is substantiated by the occurrence of tri_ovulate cones coupled with comprehensive characters of the genus. The metamorphic patterns as well as the leaf nature of the outer envelope indicate that female cones of Ephedra are compound while the female reproductive units of the ovulate cone have been reduced from secondary reproductive shoots similar to those of cordaites by phylogenetic transformation, fusion and reduction. Each fertile bract together with its axillary female reproductive unit composed the Bract Scale and Seed Scale Complex of Ephedra .

Then, a series of successful numerical simulations on the finite length inclined positively buoyant jets in uniform cross flows environment are developed. Based on the results from numerical simulations, some qualitative pictures of the complex three -dimensional mean flows are given. In terms of these pictures, the flowing behavior of the buoyant jets and the mechanism of end-vortexes generation are made a study. The change rules of end-vortexes and temperature and dilution on trajectory of jets, horse-hoof shape of buoyant jets on horizontal, the phenomenon of the jets touch wall, and the effects of diffuser length^ densimetric Foroude number % velocity ratio on buoyant jets are also given.

We drawn the predicted surface maps with the Ordinary Kriging method and illustrated in the time order to provide a visible presentation of the spatio-temporal distributions. By analyzing those maps, we found that the spatial distribution of spiders in the paddy field was similar to that of macropterous SBPH and larval SBPH, and was more similar to larval SBPH, and showed an obvious pursuing phenomenon between them, while the pursuing had a close relationship with the temporal dynamics of SBPH number. But the pursuing phenomenon was complex and influenced by factors such as the weather, the environmental conditions in paddy fields, other enemies of SBPH and other foods of spiders.
用普通克立格方法作出空间分布图,在时间序列上进行比较分析,得出稻田蜘蛛与灰飞虱成若虫的空间分布均有相似性,尤其与若虫相似性更强,表现出比较明显的空间跟随现象,且空间跟随现象与灰飞虱虫量的消长有密切的关系,但是由于天气、稻田环境、灰飞虱其他天敌以及蜘蛛其他猎物的存在等因素的影响使得其空间跟随又有着相当的复杂性。

The clinical characters of oligodontia concluded from this study are following:(1) There is significant difference that more teeth absent and more existent teeth anomalies in patients of oligodontia/S group than in patients of oligodontia/I group, and the peg-shaped upper lateral incisor is the most frequently affected teeth with shape anomaly.(2) Both of the two groups have no significant differences in number of teeth missing between maxilla and mandible as well as that between left and right side.(3) The distribution of teeth missing is bilateral symmetry in both groups, but the frequency of teeth lost are different: excluding the third molar, in oligodontia/I group, the lower second premolar is the most frequently congenitally missing tooth followed by the upper lateral incisor, while in oligodontia/S group, the most frequently missing teeth are mandibular canine and maxillary lateral incisor. Nevertheless, the first molars are the most stable teeth in both groups.(4) In oligodonita/I group, the mean mesiodistal dimensions of all type of existent teeth are significantly smaller than normal value. It is implied that oligodontia is not an isolated phenomenon, but is related to a complex of other dental changes.
对于口腔多个恒牙先天缺失的临床特点有以下初步结论:(1)综合征型先天缺牙患者较单纯型先天缺牙患者恒牙缺失数目更多,平均分别为23.9个和14.9个,且现存牙齿有更多的形态异常,分别为7/10例(70%)和6/22例(27.3%),其中最常见的是上颌侧切牙畸形;(2)两种类型的多个恒牙先天缺失患者的缺牙数目在上下颌及左右侧之间均无差别;(3)两种类型的多个恒牙先天缺失患者在缺失牙位上均呈对称分布,但在具体牙位上有所差异:不计第三磨牙,单纯型先天缺牙最常缺失的牙位是下颌第二双尖牙、其次为上颌侧切牙;而综合征型先天缺牙最常缺失的牙位是下颌尖牙和上颌侧切牙;无论何种情况,第一磨牙均为牙列中最稳定的牙齿;(4)在单纯型先天缺牙患者中,现存恒牙的牙冠宽度较国人正常值偏小,差异显著,提示牙齿形态与多个牙先天缺失有一定相关性。

The Major histocompatibility complex of Macaca mulatta, also called Mamu antigen, is a gene cluster directly related to immune response. Evolution creates the highly polymorphic nature of the MHC genes, and this leads to changes in the number as well as the function of these genes in individual Macaca mulatto, and even the emergence of species-specific genes.
恒河猴是应用最广泛的非人灵长类实验动物,其MHC基因是一个庞大的与免疫功能密切相关的基因群,在进化过程形成了Mamu基因不同的存在状态,使得不同个体的Mamu基因在数量和功能上有所差异,同时有些个体还产生了特异性的MHC基因,它的多态性和免疫反应的复杂性相对应。
