结合实际工程的运行，对实验结果及模拟结果进行对比分析，结论为：采用混合模型能够很好的模拟曝气池内气液两相流的流场；平移推流式曝气比旋转推流式底层曝气的曝气效果好；在同种曝气方式，相同工况下，20m/s的曝气速度的曝气效果要比10m/s、30m/s的曝气速度的曝气效果好。

Vitrinite and desmocollinite have a relatively low potential of hydrocarbon generation. The stable carbon isotope composition of their pyrolysis oils is heavier than that of sporinite, cutinite and oils derived from coal-bearing strata. It seems that they cannot be major macerals to generate oil, even if they occupy a majority of proportion in the organic matter of coal and coaly shale, and that they can be good gas-prone macerals at the stage of high-maturity to over-maturity.

镜质体和基质镜质体的生油潜力相对较低，其生成的液态烃类的碳同位素组成比一般煤系原油重得多，而且这些组分本身对液态烃具有较强的吸附力，尽管其在煤系有机质中所占的比例很大，仍然难以成为生成液态石油的主要显微组分，只能在高成熟演化阶段成为良好的生气显微组分。

Both UV and NIR lasers were collinearly focused into 2.0 atm Ar gas cell,when satisfying the conditions of space-time overlap,the full width at half maximum spectrum of UV could grow from 2.6 nm without interaction situation to 6.4 nm,a factor-of-2.5 improvement,which can provide a valid way for attaining sub-20fs ultrafast pulses in the range of UV.

将紫外激光与近红外激光共线聚焦注入2.0 atm氩气样品池中，在满足时空重合条件时，半高全宽的紫外频谱宽度可从无相互作用时的2.6 nm展宽至6.4 nm，增加2.5倍，为进一步获取该波段小于20fs超快脉冲提供一个重要的途径。

To remove these safety hazards, an automatic gasproducing dry powder explosion suppression system has been developed through technical improvement. The system which consists of ultraviolet sensor, controller and explosive suppressor, can be effectively used in open or half open area with some explosive gas or combustive powder.

CNG加气站现有消防设施动作时间长，不能有效防止天然气的爆炸，为此，开发研制了产气式自动干粉抑爆系统，由紫外传感器、控制器、抑爆器组成，可用于爆炸性气体场所的敞开或半敞开空间抑爆。
