As a basic disadvantage of AEF over fuel-fired melters the relative small pull range for stable operation occurs [5], because at lower glass flow rates the batch layer gets thinner and thinner, and the high heat losses do not allow to increase the melt temperatures to a level necessary for sufficient refining.

作为一项基本的缺点，阿英法比燃煤melters相对小拉范围为稳定运行的发生[ 5 ] ，因为在较低的玻璃流量间歇膜太薄薄，瘦，高热量的损失，不容许以增加熔体气温到一定程度，有必要进行充分的精炼。

A Ni-Cu based cladding was thus deposited, where the powdered Ni1015 was provided for the laser cladding process to form a smooth surface layer bonded metallurgically with Cu substrate, whose grain-refining microstructure is homogeneous, compact, void-free and crack-free.

用5 kW CO2激光器，通过优化激光工艺参数，在结晶器用铜合金表面预置添加SiC晶须的镍基自熔合金(Ni1015)粉，制备出表面平整、组织均匀致密、无气孔和裂纹等缺陷、与基体为冶金结合的Ni-Cu激光熔覆层。

In the industrial sector, the major generators of hazardous waste are the metel, chemical, paper, pesticide, dye, refining, and rubber goods industries.

在工业部门，主要是发电机的有害废物料、化工、纸张、农药、染料、炼油、橡胶工业产品。

In this paper,the authors compared extraction spectrophotometric method with gravimetric method in the determination of naphthenic acid in oil refining sewage,and found that the former method is better than the latter both in precision and operation.

讨论了萃取分光光度法测定炼油污水中环烷酸含量的测定条件和干扰因素并与重量法进行了比较，萃取分光光度法的精确度比重量法高而操作比重量法简单。

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.
