已经沟通过了，好话说尽，已经答应了的事，怎么就能反悔了，淘宝上还第一次遇到这样的买家，心里气的吐血，也不想要他改了，就是问下，这种旺旺上答应了的事，投诉淘宝能不能给处理？

But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。

From the aspect of velocity distribution,this paper made a full analysis of the flow condition of integrated oxidation ditch with submerged propeller and training wall based on the measured data.

All results above account for that CO_2 gas in Jiyang Sag have multi origin and mainly abiogenetic, and mantle is the dominating source, a few may come from biogenesis; and in the process of gas pools forming, some mantle CO_2 lost by converted to CH4 or carbonate, some crust CO_2 added into the gas pools; CO_2 gas pools in Huagou district have particular geochemical character, maybe there were some decarbonated CO_2 added into the gas pools, need further research work.

以上种种特征都说明，济阳坳陷非烃类气藏中气体具有多来源的特征，但CO_2主体是无机成因，并主要来自地幔，少量来自有机成因；在成藏过程，幔源CO_2通过转变为CH_4或者碳酸盐岩而丢失了部分CO_2，壳源CO_2和其它烃类加入到气藏中；花沟地区的气体地球化学特征与众不同，可能存在碳酸盐地层变质脱气产生的CO_2的混入，但具体原因尚待进一步研究。

Establish large deformation model of pipes under geologic disasters such as collapse and gulch; simulate and validate these formulas, and make certain of pipe' lapse length, and put forward some defendable suggestions.

基于弹性地基理论和弹性梁挠曲理论建立了埋管在坍塌/冲沟地质灾害作用下的变形微分方程，导出了大变形分析模型；以西气东输工程用管为例，由计算机仿真验证了公式适用性，确定了管道失效长度并提出了预防建议。

Express as a result that the study area gets close to hydrocarbon generation center, have high-quality coal measures hydrocarbon source rock along with big hydrocarbon generation intensity, so it has abundant gas source and the material foundation to form large scale natural gas reservoir; Evaporitic tidal flat facies of the Ordovician Majiagou Formation in this area is situated in the austral expanded range of the karstification zone, and is the optimum natural gas prospecting targets of the lower-Paleozoic; In the south of study area, there are well-developed delta deposition system sand bodies of Shanxi Formation and Xiashijezi Formation, hence this area becoming the most beneficial Neopaleozoic natural gas enriched region; In this area, the Paleozoic develop various concealed non-structured traps, the natural gas migration and accumulation process is very beneficial and both the cover and the conservancy condition are also very good.

结果表明：研究区紧邻上古生界生烃中心，发育优质煤系烃源岩，生烃潜力大，气源充足，具备形成大型天然气藏的物质基础；区内奥陶系马家沟组发育有蒸发潮坪相沉积，位于北部古潜台的向南延伸带上，是下古生界天然气的有利勘探目标；南部山西组和下石盒子组发育三角洲沉积体系砂体，是有利的上古生界天然气富集区；研究区古生界发育各种隐蔽性非构造型圈闭，天然气运聚成藏过程非常有利，封盖和保存条件也很好。

Field survey, sampling and testing were used to discuss the characteristics of soil water content between different subsidence stages. The results show that after mining collapsing, the soil water content and soil water storage capacity of subsidence area is obviously less than the nature area, especially for the fissure zone. It is indicated that the collapsing fissures are extremely disadvantageous for soil water-holding capacity and the conditions of vegetational cover on the subsidence area also confirmed this result.

现以神府东胜煤田为研究背景，选择两个主要塌陷阶段分布区大柳塔矿区双沟村原农场和补连塔矿区原补连沟村作为研究区，采用野外勘查、取样测试与室内参数分析综合研究的方法，对采矿塌陷不同阶段表层包气带土壤水分进行对比分析，结果表明，采矿塌陷后，塌陷区尤其是塌陷裂缝区的土壤含水量与土壤储水量值均小于未塌陷区，说明塌陷裂缝对土壤的持水作用具有非常不利的影响，塌陷区与未塌陷区的地表植被覆盖情况也证实了这一点。
