Using this theory, the flame structure of gas explosion in a horizontal pipe were studied, and the results show that: the gas explosion flame in a horizontal pipe is much thicker than that calculated from the former explosion theory, the intermediate products in the flame region are in separated state between the higher and lower level, and the cohesive force of the luminous body at lower level is bigger than that of the nonluminous body at higher level, there is a negative pressure region in the flame, and the flame splits easily in its propagating process.

结果表明，a水平管道内瓦斯爆炸传播火焰的厚度比以往理论计算得到的厚度大得多；b火焰区内爆炸中间产物呈上下分离状态，下部明亮发光体的内聚力比上部非发光体的内聚力高；c在火焰区内会出现负压现象；d火焰在传播过程中会发生断裂现象。

On the basis of referring the foreign and domestic literatures and systematically generalizing the former research results, firstly, from the adsorption gas, coal spontaneous combustion and the heat resolves, thesis analyzes the ignitable gas occurrence. Secondly, though the experiment station of coal spontaneous combustion, thesis obtains the critical temperature 60 ℃～ 100 ℃, splits temperature 100℃～ 150 ℃, the fission temperature 150℃～ 180 ℃ and the speed-up temperature 210℃～ 250 ℃ and ignitable gas release rules in the several temperatures sections according to the results. Finally according to fire resource and the catastrophe theory, ignitable gas explosion characteristic and the influence factors have been conducted of the qualitative investigation and the quantitative determination. The gas explosion control technologies are put forward. It has built the certain foundation for the effective prevention gas explosion accident occurrence.

本论文采用理论分析和实验模拟相结合的综合研究方法，首先从煤层吸附瓦斯、煤氧复合过程及煤高温热解三方面对采空区可燃性气体的产生进行分析；其次通过对大型煤自然发火实验测试台的应用，根据实验结果得到临界温度60℃～100℃、干裂温度100℃～150℃、裂变温度150℃～180℃和增速温度210℃～250℃等几个温度段的可燃性气体释放规律；最后根据爆炸引火源，结合瓦斯爆炸流变-突变理论，对可燃性气体爆炸特性及影响因素进行了定性研究和定量测定，提出瓦斯爆炸事故的控制对策，为有效预防瓦斯爆炸事故的发生打下了一定的基础。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
