Interaction of Two Diffusion Flames Spreading Along a Metal Substrate Wetted with Different Fuels

The paper reports an experimental and theoretical study of the interaction of two diffusion flames propagating over the surface of two different liquid fuels applied to both sides of a thin metal substrate. It is shown that in this system, there may be formation of a unified complex — a doublesided flame which has the properties of a steadystate flame with a peculiar structures. Some velocity and structural dependences for doublesided flames are determined. A mathematical model for a doublesided flame is proposed that adequately describes experimental relations. A physical model for a doublesided flame with a pulsating flame of the heavier fuel is formulated.

不同煅烧温度下形成的含氟硫A矿对水泥水化性能的影响

为研究不同煅烧温度下，含氟硫熟料中不同性能、形貌特征的A矿与水泥水化形成钙矾石的关系以及A矿对水泥水化性能的影响，采用工业原料并尽量模拟立窑内煅烧状况，对经1350℃和1425℃温度下煅烧的熟料进行了A矿形貌、A矿水化率及A矿与钙矾石形成关系等系列试验。试验结果表明，在传统的煅烧温度下（1400～l425℃）烧成的熟料．其A矿的固溶程度及A矿含量均比低温（1350℃）烧成的高；掺氟硫复合矿化剂烧制的熟料的A矿具有较高的水化速度，熟料强度较高．其制成的水泥在水化时，液相成分受高固溶程度A矿的水化所控制，所形成的钙矾石较低温煅烧的稳定．且A矿水化产物的形成与钙矾石（AFt）的形成较协调，水泥石机械强度更高。     

湿磨干烧生产线料浆脱水工艺的选择

料浆脱水是湿磨干烧的关键工艺，其脱水方法一般有过滤法，喷浆法和混合法三种，其中过滤法包括真空过滤和加压过滤两种，在国外都有应用，国内则大都用前者。南京院在皖维公司1000t/d生产线和白马山厂850t/d生产经上则采用了厢式压滤脱水法，文中就这两种过滤法的过滤工艺特点及其选择进行了分析和探讨。

Aspects of surface and environment protection in German mining areas

Hard coal mining in the German Ruhr district has a tradition of more than 200 years. Starting in the south near the river Ruhr with mining of seams near to the surface, mining wandered to the north with coal seams deeper and deeper. In the same way all environmental effects of mining wandered from south to north, as there are abandoned mining sites, contaminated areas, burning mining dumps, subsided areas and gas accesses at day ground. This all happened in a very high populated area with more than four million inhabitants. Therefore Germany has a long tradition in solving environmental problems of mining activities. The very good interaction of mine authority, mining companies and the mine workers' union is the main reason why the problems of decreasing mining activities in Germany were solved without economic, environmental or social hazards.
