But compared with those of the nineteenth century 4, technological changes remained minor and sporadic in the colonial period. It preceded the era of the cotton gin 5, steam power 6, and the many metallurgical advances 7 that vastly increased the tools available to workers.

然而，与十九世纪相比，殖民地时期的技术变革进展不大且时有中断，因为轧棉机、蒸汽机以及许多冶金方面的进步大大增加劳动者所用工具的时代还没有到来。

Products include PLC, Touch Panel, VVVF, AC servo system, power distribution control, numerical control systems, but also to the field of enterprise customers tip of technical services, technical engineering staff of the PLC, Touch Panel, inverter, servo , step, such as automation and control systems, has a wealth of practical experience in engineering, a lot of companies have successfully carried out for the system design and technical transformation projects, covering machine building, metallurgy, textile, printing and dyeing, paper making and printing, food processing, water treatment and other industries to provide better and more efficient services.

Specimens of the SBCB with different graphitizing degree were obtained in laboratory. Effects of graphitizing degree on the properties of the SBCB, including structure, thermal conductivity, thermal expansivity, resistance to thermal shock, resistance to erosion of molten iron and slag, were studied respectively.

在实验室制备了不同石墨化度的自焙碳块，并研究了石墨化度对自焙碳块的结构性质、高温冶金性能(包括恒压比热容、热扩散率、导热性、热膨胀性、抗热震性)、抗铁水和熔渣侵蚀性能及铁水渗透的影响。

Sand making machine we offer has features of high performance in going through uncrushed materials, small influence by humidity (humidity can amount to 8%), end products with cubic shape, low flakiness rate, low noise (less than 95 db) and low dust.

可广泛应用于水电、公路、建筑、水泥、金属矿山等行业的细碎作业，产品粒形呈立方体，针片状含量低，在机制建筑砂、石料以及各种冶金矿渣的破碎中更是得到普遍使用，与其它类型的破碎机相比产量功效高。

With the development of galvanization, metallurgy, leather madding, chemical industry and printing and dyeing, a lot of the waste water contain heavy metal was let into nature environment and pollute the environment badly.

随着电镀、冶金、制革、化工、印染等工业的发展，大量含有重金属的废水被排放到自然环境中，造成了严重的环境污染。

Alkaline hot-press oxidization pretreatment technology is an effective pretreatment technology which is widely used in the world for refractory gold ores.

碱性热压氧化预处理工艺是国际上通常选用的可规模开发利用的有效的难选冶金矿预处理技术。

Treating printing and dyeing wastewater and hydrometallurgy of sulphide mineral are two important tasks with practical value.

印染废水的处理和硫化矿物的湿法冶金是两个具有实用价值的研究课题。

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。
