多胎的

There were similar fetal anomalies between monoparous and multiparous pregnancy ,and also some special anomalies in multiparous pregnancy.

多胎妊娠异常与单胎妊娠大多相同，但也有其特有的异常表现。

Methods A retrospective evaluation was done for all the newborns who were born in the provincial women and children's health care hospital from 1995 to 2004-The morbidity, mortality and fatality rate were calculated for each observed year and different seasons. The influence of gender, body weight, gestational age as well as polyembryony and mode of delivery on the asphyxia was analyzed.

对近10年郑州大学第三附属医院分娩的所有活产新生儿的病历资料进行回顾性分析，计算窒息的发生率、死亡率、病死率，观察上述指标的逐年变化趋势及季节变化的情况，并探讨性别、双／多胎、出生体质量、胎龄分娩方式对这些指标的影响。

The incidence of asphyxia was also related with gender, polyembryony, birth weight, prematurity babies and aids to delivery from voginal. Conclusions The incidence of perinatal asphyxia is related with the gender, polyembryony, birth weight and gestation age as well as seasons. New resuscitation technique can reduce the morbidity of mild birth asphyxia, and no effect on the severe asphyxia as well as fatality rate.

围生期窒息的发生与性别、双／多胎、出生体质量、胎龄密切相关；新法复苏能显著降低轻度窒息的发生率，对重度窒息的发生率和窒息病死率无明显影响；窒息儿的死亡率和病死率与季节有关。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

Thus, further research was needed to discuss whicn kind of blood protein loci can be used as genetic marker of sheep prolificacy to discover the relationship between sheep prolific traits and major effect genes.

因此，关于有些血液蛋白位点可作为绵羊多胎性的遗传标记物，还需要深入研究，以更有效地揭示绵羊多胎性与有关主效基因的关系。

The results showed that there was a mutation of A → G in BMPR-IB gene in Cele sheep,Duolang sheep,Chinese Merino monotocous line and Hu sheep,which were the same as in Booroola Merino ewes.

结果表明，在策勒羊、多浪羊、中国美利奴羊多胎类型和湖羊等品种中都存在和Booroola Merino羊相同的BMPR-IB基因的突变(A746G)，而在中国美利奴羊中没有发现相应的突变。

对于多胎妊娠的女性，体重可以增加得更多一些。

Most IVF pregnancies are singletons but the rates of multiple gestations are much higher than those seen in spontaneous conceptions: approximately 30% of all pregnancies occurring via IVF are multiples, the majority being twins.

大多数IVF婴儿是独生子，但是与自然怀孕相比，IVF多胎怀孕的几率要高得多：全部IVF受孕婴儿中约有30%是多胞胎，绝大多数是双胞胎。

There were two genotypesin China Merino fecundity sheep,the BB and B+ mutation genotype was superior in Chinese merino fecundity sheep,the ewes with genotype BB and B+had 4.0 and 3.5 ovulations,genotype ++ had 1.56 ovulations averagely,The BB and B+ mutation genotypes were 2.44(P.01)and 1.94(P.01)ovulations more than with genotype ++ in the Chinese merino sheep.

绵羊的多胎是绵羊业多产、高产的基础。一般来说，家畜的繁殖性状是受多基因控制的数量性状，传统的选择方法对其遗传进展的改良是很慢的，世代间隔长。分子标记辅助选择为解决这一问题提供了新的方向和契机。

Institute breeding stock is set up to recruit renowned experts at home and abroad as 8 full-time technical staff of Small Tail Han purebred, South Africa Department of the improved Boer goat 2-6 generations, Luxi Cattle, Simmental, Limousin cattle, dairy cattle excellent breeding stock of Baotai, multiple births breeding, meat quality improvement projects such as embryo transfer research.

现成立种畜研究所，聘请海内外知名专家8人作为专职技术人员对小尾寒羊纯种、南非系波尔山羊的改良2-6代、鲁西黄牛、西门塔尔、利木赞牛、奶牛等优良种畜的保胎、多胎繁育、肉质改良、胚胎移植等项目进行研究。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
