The hermaphroditic organ consists of hermaphroditic gland, hermaphroditic duct,fertilization chamber,hermaphroditic conduit,atrium genitale,an...

本文仅对其生殖季节的生殖系统进行解剖研究。结果与北方种类的生殖系统有所不同；并在前人的基础上有所进展。

The same situation is on the problem of ectogenesis after man's death, which also face the same problems too. it will bring out the assault to the existing social family's structure, and the materialization of child, the violation of the individual's right to make his own decision, and the violation of " human nature dignity " principle, if the law allow to ectogensis after man's death .

同样的情形，在取后进人工生殖之问题探讨上，也面同样的问题，开放后人工生殖，也会对现有的社会家庭结构产生冲击，亦有是否为纯粹满足大人的欲望而将小孩子物化的隐忧，及进后人工生殖得过程中是否尊重个人「自主决定权」之使，有无违背「人性尊严」原则，，，等等问题。

The results showed that the reproductive system of female adult was constituted by a pair of ovaries, a pair of lateral oviducts, median oviduct, bursa copulatrix, spermatheca, genital chamber and ovipositor. The reproductive system of male adult was constituted by a pair of testes, a pair of vas deferens, a pair of male accessory glands, ejaculatory duct and penis.

结果表明：雌成虫的生殖系统由1对卵巢、1对输侧输卵管、中输卵管、交配囊、受精囊、生殖腔和产卵器组成；雄成虫生殖系统由睾丸、1对输精管、1对附腺、射精管和阳茎组成。

In this paper, a list of apomitic species of Paspalum is given. The cytological and embryological bases, and the characters of apo...

对雀稗属无融合生殖的分布、无融合生殖相关的细胞学和胚胎学基础、无融合生殖的特点及其遗传学和分子生物学研究进展进行了综述。

Finally, because cnx-1 can further increase the germ cell death in ced-1 mutant, and the phenotype can be rescued by introducing cnx-1::gfp into the cnx-1; ced-1 double mutants, we suggest that cnx-1 acts in the engulfing cells other than the dying cells during the engulfment process of germline apoptosis.

除此之外，我们亦分析了cnx-1突变下ced-1(e1735)品种虫体之生殖母细胞的细胞死亡数量，发现cnx-1突变会额外地再提高ced-1突变下线虫生殖母细胞的死亡数量，且此现象可被外加入之cnx-1：：gfp 所消除；这两现象显示出cnx-1在线虫生殖母细胞的细胞尸体吞噬过程亦具有功能。

The life-cycle of C.baileyi in Beijing duck and in the CAM of chicken embryowas studied with both the light-microscope and the Nomarski interference-contrastmicroscopy.The results indicated that the life-cycle within duck was simillar tothat of CAM.It included excystation, merogony,gamogonyand sporogony.The thin-walled oocyst was first observed and described in China.

借助普通光学显微镜和微分干涉显微镜对C.baileyi在北京鸭体内的生活史和在鸡胚绒毛尿囊膜上的生活史进行了较详细的研究，结果表明：C.baileyi在北京鸭体内和在CAM上的生活史相同，主要包括"脱囊—裂殖生殖—配子生殖—孢子生殖"四个阶段。

A structure bearing or consisting of a reproductive organ or part, such as a reproductive polyp or bud in a hydroid colony.

生殖芽体有生殖器官或部分生殖器官的结构，如再生性珊瑚虫或螅状群的芽体

In particular, it has remained unclear how oogamy arose from isogamy, a more simple form of sex in which ery similar reproductie cells take on different "mating types" but do not differentiate as distinct sperm and egg.

尤其是异配生殖如何由同配生殖转化而来，我们对此还懵懵懂懂。同配生殖是一种更为简单的结合形式，在此过程中，非常相似的生殖细胞不管三七二十一地就与不同的配子结合，都不分这些配子是"公"是"母"。

Research has been put out on several main reproduction hormaone's variations on the white geese in West Anhui during reproductive and nonreproductive periods.

本文研究了皖西白鹅雌鹅几种主要生殖激素在生殖期与非生殖期的变化情况。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
