跪求英语大神帮我翻译！毕业论文摘要（不要翻译工具翻译的谢谢）

其实前面几句，百度翻译也不错。试翻一段，请参考。
Coal gangue is the solid waste disposed during coal mining and washing, and is one of the largest industrial solid wastes in China. Large stock of coal waste not only takes up farmland, but also causes serious environmental pollution. Therefore, the treatment and effective use of the coal mining waste has become an urgent issue to be solved. The most popullar way for utilization of coal gangue is cement admixture. Due to the relatively lower activity of coal gangue, its effective utilization is limited, and to stimulate its activity is an effective measure to expand the use of coal gangue.

In this project,  the thermal activation of coal gangue and the factors to affect its activity under different conditions are studied. The influences of calcination temperature, retaining time and cooling method on activation was studied. Analyses methods such as X ray diffraction (XRD), infrared (FTIR), active silica dissolution, and ash activity were used to thoroughly understand the activation prosess. The results show that best activation is achieved at the temperature of 700℃ and with a retention time of 2 hours and natural cooling.

Coal gangue is the solid waste residue discharged during coal mining and washing, and is one of the largest industrial solid wastes in China.. The coal waste not only takes up the farmland, but also has the serious pollution to the environment. Therefore, it has become an urgent problem for our country to deal with the coal waste and to use it effectively.. The most extensive way to the use of coal gangue is used as cement admixture, due to the relatively low activity of coal gangue itself, limiting the utilization of it, expand the use of coal gangue is an effective measure to stimulate the activity of coal gangue.
The research on the thermal activation of coal gangue and the factors of its activity under different conditions are studied.. The influence of calcination temperature, residence time and cooling method on the activation of coal gangue was studied.. X ray diffraction (XRD), infrared (FTIR), active silica dissolution, and ash activity were used to analyze the activation of coal gangue.. The results show that the best activity of coal gangue is at the temperature of 700 and the retention time of 2 hours and the natural cooling method..
