To be examined the quality variation of the oxidated coal, two kinds of coal samples, blind coal and bituminous coal, were selected and heated in a series of temperature environments.

为探讨煤在氧化后发生的性质变化，选取无烟煤和烟煤2种煤样，在不同的温度下进行加热。

The concentration distribution of pulverized coal in blowpipe of blast furnace was measured in an isothermal two-phase model by means of a computer measuring system based on infrared transmission.

利用开发的红外透射法粉体浓度计算机测定系统，在高炉氧煤喷吹气-固两相流动模拟装置上测定了氧煤枪的煤粉浓度场。

Based on the study of gas solid flow field in blowpipe of BF with oygen enriched PCI, the oxygen and coal concentration distribution inside the blowpipe were simulated and discussed, including the influence of position and inserting angle of the oxygen coal lance, the pattern of the oxygen enriched jet, as well as grain size of the coal.

在对高炉局部富氧喷煤直吹管内气固两相流流场研究的基础上，对直吹管内氧和煤粉的浓度场进行了数值研究，包括氧-煤喷枪的插入角度和枪位、局部富氧射流的漩流数以及煤粉粒度的影响。

In the process of pulverized coal injection into blast furnace, the blowpipe plays an important role in pre mixing the pulverized coal and oxygen, pre heating them and improving the pulverized coal pyrolization and combustion of the coal.

在高炉富氧喷煤过程中，直吹管使喷入的煤粉与氧气预混、预热，并促使煤粉的热解和部分煤的燃烧。

On the basis of slip-diffusion model of multiphase flow, a three-dimensional mathematical model of gas-particle flow in blowpipe has been developed and debugged to calculate the gas-solid two phases flow, including gas velocity and particle velocity inside the blowpipe.

运用多相流的拟流体模型建立了高炉局部富氧喷煤直吹管内气粉两相流动的数学模型，对气粉两相流场进行了数值研究，探讨了气相和煤粉的速度分布规律及其影响因素，其中包括氧-煤喷枪的结构、漩流数和富氧率等。

This paper introduced the development of briquette production line ,including the technical process and the main equipment.

介绍了自行开发设计的一条连续型煤生产线的工艺过程和主要生产设备，重点介绍了对辊式型煤成型机的工作原理及结构特点。

Briquette binder is a key technology in the area of briquette production.

型煤粘结剂是型煤生产的关键技术。

It can increase the briquette quality and open up the briquette market.

将有助于提高型煤质量和开拓型煤市场。

The results show that the briquette begins to shrink at 400℃, and has two shrinkage ranges at 400℃~550℃ and 650℃~800℃.

结果表明，400℃左右时型煤开始发生收缩，400℃～550℃和650℃～800℃是型煤发生收缩的两个高峰阶段，1000℃体积收缩率达32％～44％。

In order to improve the quality of briquette,many countries are carring on the research work on binders based on respective conditions of those coutries.

为了提高型煤的质量，许多国家根据各自的国情对型煤粘结剂进行了大量的研究。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
