On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

本文在大量测试工作基础上，利用煤岩学与有机地球化学资料，分析了煤系油气的来源，认为本区延安组煤系煤层生油潜力差，煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生，油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系；通过对煤层及围岩一系列物性参数的测试，分析与评价了煤岩层的生、储、盖、渗性能与可抽放性，得出主采4_(-2)号煤层属中等储集、低渗透层，围岩封闭性差，渗透性高，煤层瓦斯含量低，而顶板砂岩瓦斯含量高，为采面瓦斯涌出的主要来源。

Water treatment system of the power Plant adopts traditional electro deionization exchange of water processing craft, that craft exists high operating costs in the production and instability in the decimalized water, water loss, high energy consumption, complicated to operate, the personnel labor strength greatly etc.

热电厂化学水处理系统采用传统的电渗析＋阴、阳离子交换的水处理工艺，该工艺在生产运行中存在着运行费用高、出水水质不稳定、水损失量大、能耗高、操作复杂、人员劳动强度大等缺点，不但水资源浪费较为严重，而且排放的酸、碱废水对环境造成了新的污染。

Combined with investigation results of the furnace body erosion before relining, this paper analyzes the cause of production problems appeared in the first campaign life of the blast furnaces. Because of the existence of design shortcomings in large cooling block and bosh cooling stave, it resulted in poor furnace performance, such as stronger peripheral gas flow and irregular profile. The quick rise of bottom temperature of No.7 BF was caused by the penetration of molten iron into the joint of bottom carbon block, wheresas the quick rise of bottom temperature of No.6 BF was due to gas fleeing through the furnace bottom.

结合大修前炉体破损情况，对这两座高炉第一代炉役生产中出现的问题进行了调查研究。7号高炉大型模块和炉腰冷却壁设计上存在不足，引起高炉边缘气流发展，操作炉型不合理，炉况不顺；7号高炉炉底温度偏高是炉底炭砖渗铁造成的，6号高炉炉底温度偏高是炉底串煤气所致；7号高炉铁口失常的主要原因是铁口组合砖损坏严重和该部位炉壳开裂。

In the paper, we investigate, respectively, the unsteady transport properties of heat and moisture in enclosure under constant wall heat flux and constant wall temperature when porous particles are small and Darcy number is lower, the effect of conductivity ratio, heating conditions and other parameters on the heat transfer rate of enclosure when particles are larger and Darcy number are higher.
