平均数

The mean of n numbers expressed as the reciprocal of the arithmetic mean of the reciprocals of the numbers.

n数目中取其倒数之平均数之倒数为值的平均数。

And use frequency formula or weighted harmonic mean formula of weighted arithmetic mean formula to get its mean value.

利用加权算数平均数的频数公式或加权调和平均数公式求其平均值。

Result］ The annual mean value of azotobacter,ammonifiers and nitrobacteria in the river water were 140,1 179 and 691 CFU/ml resp.,the yearly average of nitrosation and denitrifying bacteria were 647 and 369 MPN/ml.

结果］ 水体中固氮菌、氨化细菌、硝化细菌年平均数分别为140、1 179和691 CFU/ml，亚硝化和反硝化细菌年平均数分别为647和369 MPN/ml。

The research for the means has a long history, the classical means include algebraic mean, geometric mean and harmonic mean etc.

平均数理论研究的历史久远，经典的平均数包括算术平均，几何平均，调和平均等。

Harmonic mean : A special kind of mean which is determined by calculating the mean of the reciprocals of the values concerned and then calculating the reciprocal of this quantity.

调和平均数，倒数平均数：一种特殊的均数，求得方法是先求出有关倒数的均数，再求出这一均数的倒数。

Harmonic mean : A special kind of mean which is determined by calculating the mean of the reciprocal s of the values concerned and then calculating the reciprocal of this quantity.

调和平均数，倒数平均数：一种特殊的均数，求得方法是先求出有关倒数的均数，再求出这一均数的倒数。

When using relative number or average number to get averaging, you may use denominator or numerator of this relative number or average number as weight number to weigh the relative number or average number,and use frequency formula or weighted harmonic mean formula of weighted arithmetic mean formula to get its mean value.

在由相对数或平均数求平均数时，可以以这一相对数或平均数的分母或分子为权数，对这一相对数或平均数进行加权，利用加权算数平均数的频数公式或加权调和平均数公式求其平均值。

We introduce a new type of trimmed mean, called the mode type trimmed mean.

我们介绍一种新的截尾平均数，称为众数截尾平均数。

Moreover, an extension of this new type of trimmed mean to construct a new Winsorized mean will also be introduced and studied.

更进一步介绍及探讨由众数截尾平均数延伸建构出的一种新的 Winsorized 平均数。

The contents of the curriculum must be acceptable by the teachers on the impelling of educational activities thus teachers hold an approval view towards the concept of using Ecological engineering method on straightening Old Zhuoshui (avg. rate 4.1). The teachers also assume that this subjects is acceptable in merging with the teaching of elementary schools environmental of education (avg. rate 3.92). Thus, this idea coheres with the everlasting preservation of the environment (avg. rate 4.08), and that teachers are willing to impel and participate in the exercise of using this issue on education within a year (avg. rate 3.51). It proves that this idea of Ecological engineering method is suitable for use of teaching environmental education issues.

教学活动推动时，其课程的内涵是需受教学者的肯定，而教师对於旧浊水溪以生态工法整治是持认同的态度(平均数4.1)，也认为此议题适合融入小学环境教育的教学(平均数3.92)，并可符合维护生态与环境永续发展的理念(平均数4.08)，且在未来的一年内教师愿意推动及参与此议题运用於教学上(平均数3.51)；显示生态工法的工程思维是适合做为环境教育议题的教学。

It goes back to what I told you...

现在回到我告诉过你的。。。

With a supporter in Mr Charest and an admirer in Mr Dumont, Mr Harper may be encouraged to call an election himself.

由于在沙雷那边有个支持者，杜蒙那边有个崇拜者，鼓励哈珀为自己举行一次选举。
