查询词典 multiparas

Objective: Our purpose is to analyse the cesarean section rate and the operative indications in the multiparas to accumulate the clinical experience.

目的：对经产妇再次分娩时的剖宫产率及手术指征进行分析，总结临床经验。

Methods: 311 multiparas who delivered the second babies in our hospital from January 1999 to December 2003 were collected to analyse the cs rate and the operative indications.

1999年1月~2003年12月期间在仁济医院产科分娩且符合条件的经产妇311例，统计其剖宫产率及手术指征，并加以分析。

Results: The cs rate is 29.90%, and the first cause of it is due to fetal distress (13.50%); the second is macrosomia (6.11%). Among those multiparas who delivered the second babies in years later the incidence of relative cephalopelvic disproportion is much higher.

结果：经产妇的剖宫产率为29.90%，其手术指征中首位是胎儿宫内窘迫，占13.50%；其次是巨大儿，占6.11%；相隔10年以上再次分娩的经产妇更易发生相对性头盆不称。

Fetal distress is much common in the multiparas, so we must operate in due time; the following is macrosomia, the management must be taken individually; the cs rate is much higher in those who delivered the second babies 10 years later, of which the incidence of relative cephalopelvic disproportion is significant difference.

胎儿宫内窘迫是经产妇剖宫产术的首要原因，及时手术是避免围产儿预后不良的重要措施；因巨大儿手术者居其次，对分娩方式应个体化考虑；相隔10年以仁再次分娩的经产妇剖宫产率较高，更易因相对性头盆不称而不得不手术终止妊娠。

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。
