The Jaccard coefficient was worked out by using NTSYS-pc software, and a cluster dendrogram of different samples was established based on unweighed pair-group method with arithmetic mean.

采用NTSYS-pc软件计算瓜萎各农家品种间的Jaccard遗传相似系数，按非加权配对算术平均法建立各品种间的聚类图。

Unweighted indices are simple arithmetic or geometric averages.

不加权的指数指简单算术平均或几何平均数。

Methods A total of 36 patients with advanced renal cancer were definitely diagnosed by IVP, US, CT or MRI examination. A 5F Yashiro catheter was introduced into the femoral artery with Seldinger's technique under local anesthesia, abdominal aortagraphy and renal arteriography in both sides of kidneys were performed routinely to display the blood supplying arteries of tumor, thereafter, renal embolization was performed under superselective catherization for chemotherapeutic embolizing. Then the clinical effect was observed, the amount of blood loss and the operation time were recorded. All these results were compared with that of randomly selected 17 patients before surgical operation with advanced renal cancer admitted during the recent 3 years but without embolization.

36例中晚期肾癌患者，均经临床检查、静脉肾盂造影、B超、CT或MRI检查而确诊；采用Seldinger's技术，局部麻醉下经一侧股动脉穿刺插管，引入5F Yashiro导管，常规行腹主动脉及双肾动脉造影，以显示肿瘤的供血动脉，再将导管超选择插管或尽可能接近肿瘤病灶，进行化疗栓塞，观察其临床改善情况，计算术中失血量及手术时间，并与随机抽取我院近3年所做的17例术前未行肿瘤供血动脉栓塞的肾癌患者进行对照。

The synthetic nourishment index method averages the trophic index of all parameters, and then evaluates the degree of the eutrophication. The total composition analysis nourishment evaluation colligates all kinds of representative parameters, and then evaluates the degree of the eutrophication. The grey system theory method evaluates the degree of the eutrophication through a series of calculations, such as constructing situation and situation matrix, confirming object degree, and so on.

总成分分析营养度评价法是通过对各单因子的分营养度进行算术平均，将水体营养状态连续分级；综合营养状态法是综合多项富营养化代表性指标，将其表示成指数，对水体营养状态连续乡级；灰色系统理论法是通过构造局势与局势矩阵、确定目标效果测度、多目标决策、确定最优局势等一系列系统分析计算，判断水体富营养化级别。

The conclusion indicated that the consistency of GMJ was less than the mean of the consistencies of judgments.

结论表明，几何平均综合矩阵的一致性指标要小于各决策矩阵一致性指标的算术平均数。

During the design, in order to reduce the influence of interference, a method of eliminating extremer digital filter is adopted. It makes the data closer to actual value.

在软件设计中，根据煤炭实验的环境，采用了去极值的算术平均滤波方法，较好的控制了干扰源的影响，使得采集的数据更加接近真实值。

A method is a named algorithm that manipulates the data values in the object.

一个方法是一个被处理这个资料数值的算术命名的在这物件中。

This may sound simple, but it never ceases to amaze me how poorly and slowly most beginners count.

这听起来可能很简单，但大部分新手的算术水平之差和计算速度之慢却常会令我吃惊。

You need to learn simple math; two multiplied by two equals four and so on.

你需要学些简单的算术，例如2乘2等于4这样的。

Matter of elementary arithmetic, and if the beginner neglects it, he will soon be at a

初级算术的问题，而如果初学者疏忽它，他将很快导致一场

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.

交际能力和语法的关系应该是目标与途径的关系。
