Methods The pregnant rats mating in the corresponding period were divided into four groups.As for the Nepionic Rats at the body growth characteristic of different days ages,the method of observing the distance and the relative distance of the anus and the vulvas when they were three to four days old was used to discriminate the sex.When they are five to eight days old,the method of observing the papillas was added to discriminate the sex.

将同期交配的孕鼠分为4组，针对乳鼠在不同日龄的身体发育特点，在3～4日龄采用观察其肛门与外阴距离和相对距离的方法、对5～8日龄再附加对乳头观察的方法进行性别鉴别对比实验。

Finally, the conclusions are applied to over-voltage models based on three-phase nonsynchronous closing of switches appearing in the power systems, the results in accord with the background physical meaning are obtained.

最后，将所得结论应用到电力系统中三相非同期合闸的过电压模型中，结果表明所得结论与实际背景的物理意义相吻合，同时结论的所有条件较容易验证，因此该结论具有一定的理论意义并便于在实际中应用。

Methods 134 cases frome May to July 2003 in our hospital were allocated to observation group,while 115 cases during the same period of last year to control group.All the objectives were in proper age,term birth and nulliparous. differences between the two groups were observed with regard to the duration of labor stage,postpartum hemorrhage,neonatal asphyxia,the rates of super-quality delivery and maternity satisfaction.

以我院2003年5～7月分娩的134例产妇为观察组，以前1年同期分娩的115例产妇为对照组，两组产妇均为无产科合并症适龄足月初产妇；比较两组的产程、产后出血、新生儿窒息、优质接生率和产妇满意度情况。

The analyses of the meterological and oceanographical data from seriel observations aboard R/V Xiangyanghong 5 during the voyage of joint AMEX experiment by Australia,China and the United States show that (1) there is high level of humidity within middle and low layers of troposphere at the initial stage of a typhoon's formation,and once a typhoon has fully developed,the highest level of humidity remains within middle layer of tropisphere;(2) although small vertical wind shear is a requisition for a t...

对中、美、澳三国AMEX试验期间&向阳红5号&定点观测到的气象和海洋资料分析得出：①台风形成前，大气整个中、低层空气湿度较大，台风一旦形成，大气湿度最大层主要集中在中空；②风速垂直切变小，对形成台风是一个必要条件，但并非整个对流层风速切变都小，而且不同地区形成的台风，风速切变状况是不同的；③厄尔尼诺年南半球与北半球对应位置同期的θ_G、θ_8、Q_b相差不大，但是南半球的θ_c较北半球的大。

Vagina sponge bolt and CLO was used in oestrous synchronization of donors and acceptances , the rates of estrus was100.0% and 83.0%. 6mg FSH and CLO was used in superovulation of Hexi Fine wool goat,115 embryos were acquire totally and average14.4 embryos,100 useful embryos, average 12.5 embryos.The surgical operation used in embryos transplant, the rate of Gestation was 82.4%, 47 lambs was birth,and the birthrate of lamb was 167.9%.

采用阴道海绵栓结合氯前列稀醇法对供、受体进行同期发情处理，处理结果的发情率分别为100.0%和83.0%；采用 FSH剂量6m g/只结合氯前列稀醇对河西绒山羊超数排卵，共回收胚胎115枚，头均14.4枚，可用胚胎100枚，头均12.5枚；采用手术法对杂种河西绒山羊受体移植后，妊娠率82.4%，产羔47只，产羔率为167.9%。

Estrus synchronization can be applied such as heat control technology, so that timely focus on oestrus ewes in a relatively short period of time breeding, pregnancy rate, subject to higher distribution, fully furnished full of school-age ewes, but also to improve the quality of the lamb.

同期发情，可如热控制技术的应用，以便及时对发情母羊集中在一个时间繁殖，怀孕率，受较高的分布，相对较短的时间齐全学校全年龄的母羊，而且提高羔羊的质量。

The first experiment: it is separately dealed with CIDR (treatment 1), CIDR + PG (treatment 2) and (treatment 3) to compare the oestrus synchronization effect.

实验一，分别用CIDR(处理1)、CIDR+PG(处理2)、CIDR+PG+PMSG(处理3)处理徐淮山羊比较同期发情的效果。

研究非血管化骨移植同期种植的可行性，具有比较重要的的临床价值。

From Apr.1st to Oct. ninth, when two-year-old Onobrychis viciaefolia 、one-year-old Onobrychis viciaefolia 、Triticum 、Triticum aestivum/ Vicia villosa 、Triticum aestivum/ Brassica campertris 、Triticum aestivum-Vicia villosa and Triticum aestivum-Brassica campertris are planted, their content of soluble salt in 0～20cm soil layer are lower than that in uncovered soil, in the period of harvest , they decrease 0.361%、0.331%、0.141%、0.327%、0.312% and 0.317% respectively.

从时间变化分析，采用二年生红豆草、一年生红豆草、单作小麦、小麦/毛苕子、小麦/油菜、小麦-毛苕子和小麦-油菜7 种绿色覆盖模式时均使土壤表层盐分含量比同期裸地的低，生育期末分别降低了0.361%、0.331%、0.141%、0.327%、0.312%、0.321%和0.317%。

Methods A total of 2 285 community residents, at the age of 51±16 years, from 4 different communities in Beijing, were randomly recruited in this cross-sectional investigation. Questionnaire was used to collect their medical history. Their PWV was detected by oscillometry. Laboratory tests were performed to detect their basal biochemical parameters including serum glucose, uric acid, lipid, and creatinine.

北京4个社区入选2 285名18-96岁居民，平均年龄51±16岁，用问卷调查方法采集病史，自动示波测量仪检测PWV，同期化验血脂、肌酐、尿酸、血糖等指标，简化的MDRD公式估测肾小球滤过率。
