抽样分布

With these conclusions,we present an accurate algorithm to solve the simultaneous inequality of binomial PDF.An optimum solution can be worked out by adopting multivariate half-folded searching algorithm,so that we can get the sampling plan of testability demonstration accurately and quickly.

根据这些结论，提出了求解二项分布的联立不等式的精确算法，在可能的求解区域采用多变量折半搜索的算法，确定联立不等式的最优解，从而可以快速准确地获得测试性验证的抽样方案。

Results All the BMI values of means, medians and percentiles of male adoleseents were significantly higher than those of female.

方法采用整群抽样的方法，随机抽取长沙市内4所中学，收集2004～2006年11～18岁学生的健康监测数据，分析BMI的分布特点，并与中国学龄儿童青少年BMI超重、肥胖标准进行比较。

The key technologies of Grid Method including grid divided in basin, impact radius of rainfall and number of reference rainfall stations have been discussed with example. The parameters of Grid Method have been selected through trial and error. Using simple random sampling to simulate the failure to collect rainfall, the relation between surface rainfall calculation error and station density, station distribution, uneven spatial distribution of rainfall has been sought.

论文探讨了流域网格剖分、降雨影响半径、搜索半径范围和参证站数量等关键技术，研究了网格法参数的优选，并采用简单随机抽样模拟降雨缺测情况，给出了面雨量计算误差与流域站网密度、均匀度、降雨分布不均匀性指标的关系。

The present paper reports the phenotype and gene frequencies of GLOI of 7 nationalities in Inner Mongolia province, including the nationalities of Han, Ewenki, Dawuor, Orogen, Buryat,Northeast and Northwest Mongolian, using mixed starch/agarose gel electrophoresis.

应用琼脂糖水解淀粉凝胶平板电泳法，对中国内蒙古呼盟鄂伦春、鄂温克、达斡尔、布里亚特、蒙古人及包头市蒙古族、汉族人血GLOI遗传多态性进行了调查，抽样检测7个群体GLOI表型分布频率，计算出基因频率和识别能力。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
