The total pregnant women took part in the urine testing of mercury was 2,190. The mean, median, minimum, maximum, 95%CI were 2.58ug/kg, 1.66ug/kg, 0.01ug/kg, 62.07ug/kg, 2.42-2.74ug/kg respectively, and the quarte range was 1.79ug/kg.

孕妇孕期及其新生儿内环境汞暴露现状本次孕妇尿汞检测总计有效2190例，算术平均值为2.58ug/kg，中位数为1.66ug/kg，最小值为0.01ug/kg，最大值为62.07ug/kg，95％CI为2.42-2.74ug/kg，四分位数间距为1.79ug/kg。

For example, Rahman and Frair suggest a simple arithmetical total.

举例来说，拉赫曼和frair推荐一个简单的算术总额。

Eight hierarchical clustering methods including single linkage method, complete linkage method, median linkage method, centroid method, unweighted pair-group average method, Wards method, flexible-beta method and weighted pair-group average method were combined with three sampling strategies, random, preferred and deviation sampling to develop 24-core collections.

川最短距离法、最长距离法、中间距离法、重心法、不加权类平均法、离差平方和法、可变法和加权配对算术平均法等8种系统聚类方法，结合随机取样法、优先取样法和变异度取样法等3种取样方法，发展了24个水稻核心种质库。

The typical Arithmetic Coding does not map a single source to a word, but maps the whole input symbol sequence to a section of 0,1 on the real number axis, the width of which is equal to the probably of the sequence. A representative binary fraction in the section is chosen as real output to get efficient compressed codes.

典型的算术编码不是将单个的信源符号映射成一个码字，而是将整个输入符号序列映射成为实数轴上0，1区间内的一个小区间，其长度等于该序列的概率；在该小区间内选择一个代表性的二进制小数，作为实际的编码输出，从而达到了高效编码的目的。

And at the age of 20, his opportunity had arisen The king asked him to design a palace roofed with an arisen.

其中一个说的是关于建筑师建筑师算术阿拉伯在他 20 岁那年，他的机会出现出现了。

In this article, the effect on the surface topography of the same material was analyzed by different processing methods, the value of surface parameter arithmetic mean R, root-mean-square roughness R and gradient root-mean-square value Z were used to appreciate the surface topography, and the data were processed with the software Matlab.

分析不同加工方法对同一种材料表面形貌的影响，采用表面形貌统计参数中的轮廓高度算术平均值R、轮廓高度均方根值R、坡度均方根值Z，对表面形貌进行评价，结果表明，准分子激光加工表面的R、R，和Z，值均比研磨加工表面小。

In this article, the effect on the surface topography of the same material was analyzed by different processing methods, the value of surface parameter arithmetic mean Ra, rootmean-square roughness Rq and gradient root-mean-square value Zq were used to appreciate the surface topography, and the data were processed with the software Matlab.

分析不同加工方法对同一种材料表面形貌的影响，采用表面形貌统计参数中的轮廓高度算术平均值Ra轮廓高度均方根值Rq、坡度均方根值乙对表面形貌进行评价。

The experimental results indicate that prime root-mean-square deviation measured by this method is almost linear with the arithmetical mean deviation of the surface-samples.

实验结果表明，应用本测量方法得到的轮廓均方根偏差最佳估计值σp与表面样品给定的轮廓算术平均偏差Ra成很好的线性关系。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
