fertilization rate meaning in Chinese
受精率
Examples
- The optimum fertilization rate , population density and variety in these experiments have recommended to farmers
已将试验所得最佳施肥量、种植密度和品种推荐给农民。 - According to the best real time kinematics positioning , we could transmit the positioning coordinate to a field computer for estimating the fertilization rates by a decision support system
藉由无线电即时动态定位之传输，将定位座标传至电脑程式，可以提供施肥决策专家系统用以估算施肥量。 - Through 3 - year field experiment , mathematical models were established for yields of spring and winter wheat , soil wetness , designed irrigation depth and fertilization rate . 8
6 .通过三年田间试验，建立了喷灌条件下冬小麦、春小麦产量与土壤湿度、计划湿润层深度和追肥量三因素间的数学模型。 - Materials and methods the mouse , golden hamster and human sperm were incubated with endotoxin in different concentration for different time to get capacitation , respectively , and ar was induced by progesterone after capacitation , then the rates of capacitation and ar were detected by chlortetracycline ( ctc ) and hoechst 33258 fluorescent staining method . the medium was with endotoxin in different concentration in sperm - oocyte fusion step during ivf , then the fertilization rate was observed . the 1 - cell , 2 - cell and zona - free 2 - cell mouse embryos were incubated in the medium with endotoxin , then the rate of blastocysts was recorded
方法取小鼠精子10份、金黄地鼠精子6份、人新鲜精液标本10份及人冷冻精液标本9份，分别与不同浓度内毒素共孵育进行体外获能和孕酮诱导的顶体反应，应用金霉素和dna结合的荧光染料hoechest33258双重荧光染色法检测精子的获能率和顶体反应率；小鼠体外受精实验的精卵结合环节培养液中加入不同浓度的内毒素，观察受精情况并记录受精率；取小鼠1 -细胞胚胎、 2 -细胞胚胎和去卵透明带2 -细胞胚胎，与不同浓度内毒素共孵育进行体外培养，观察体外发育情况并记录囊胚率。 - The results were as follows : ( l ) the pre - incubation of pmr induced the exocytosis of the cortical granules ( cgs ) in the oocytes and reduced the quantity of the microvillus on the surface of oocytes ; ( 2 ) the matrix of cg might migrate to the surface of plasma membrane of oocytes after pmr pre - treatment . ( 3 ) incubation of zona - free hamster eggs with spermatozoa pretreated with pmr a ntiserum was associated with a dose - dependent significant reduction in the number of spermatozoa binding to the oolemma , compared with a contraband with a dose - dependent reduction of the fertilization rate and the penetration index . the results indicate that mr of human sperm plays an important role in sperm - oocyte fusion and oocyte activation
结果显示： ( 1 )人精子mr能够诱发去透明带金黄地鼠卵母细胞中皮质颗粒的胞吐，并引起卵母细胞膜表面微绒毛形态和数量发生改变； ( 2 )皮质颗粒胞吐后，其内容物可结合到卵膜表面； ( 3 )抗mr抗血清预处理精子可抑制精子与卵子的结合与融合，使受精率、穿透指数和结合指数下降，并均有剂量依赖性。以上结果提示，人精子mr在受精过程中起重要作用，其主要作用可能是介导精-卵膜融合并促进卵母细胞的活化。
