平均值法

This aerage is then applied relatie to the surface normal at the current location.

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。

METHODS: Employing Health-Carter method, the 218 college students were measured on the indexes of biepicondylar breadth of the humerus, biepicondylar breadth of the femur, tricps skinfold, subscapular skinfold, suprailiac skinfold, medial calf skinfold, body length, body weight, upper arm girth flexed and tensed and calf girth. Every index was measured 3 times and average values were adopted, and compared to that of other regions.

方法］根据染色体相对长度、臂比，以及它们的平均值、方差、极差、标准差等参数，计算了13种双壳贝类之间的核型似近系数，用UPGMA法对它们的亲缘关系进行了聚类分析。

The big advantage of the Jackknife is that they can be used to evaluate the statistical properties of a statistic that is related to the data in a complicated, nonanalytical way. Apart from estimation of standard deviation, Jackknife can be used to estimate mean, median and even to construct confidence intervals.

大折刀法的最大优点是它能在一个统计量与资料的关系很复杂或无解析的表达式时，可用它估计统计量的统计特性，除了能得到标准偏差外，还可用来估计平均值和中值，甚至构造置信区间。

Relative contents of four main cellular proteins corresponding to MALDI-TOF-MS peaks m/z 4466, m/z 6455, m/z 6514, and m/z 7772 were all found to be close correlated with the concentration of melamine, although their up- and/or down-regulations showed different patterns when the concentration of melamine changed. Support vector regression leave-one-out method, with the optimized polynomial kernel function and a poly-degree of 3, was chose to evaluate the correlation between the alteration of Tetrahymena pyriformis main proteins'relative contents and the concentration of melamine in the culture medium.
