1.Aim at the present condition that the permeability of high rank coal reservoirs and its dynamic change regulation have been rarely studied, based on the modern testing technologies and actual measure data of Coalbed methane (CBM) well with better drainage effect in Qinshui Basin, using the international advanced CBM well numerical simulation software (COMET2), the dynamic change regulation of the permeability of high rank coal reservoirs during gas recovery has been discussed, using the gas and water recovery process in divided stage is matched.
摘要针对高煤级煤储层渗透率尤其是其动态变化规律极少开展研究的现状,基于现代测试技术和沁水盆地排采效果较好的煤层气井实测排采数据,利用目前国际上较为先进的煤层气数值模拟软件COMET2,采用分段拟合的方法对煤层气井的产气、产水过程进行历史拟合和修正,进而对高煤级煤储层渗透率在开采中的动态变化规律进行了探讨。

3.[Methods] The models of DNA damage of ccc-HPF-1 cells were established by treatment of the cells with B(a)P plus S9 at 10 to 100 μmol/L for 3 hours with or without 24 hours recovery for DNA repairing. The DNA damage was detected by single cell gel electrophoresis assay, SCGE (comet assay).
[方法] 建立ccc-HPF-1细胞DNA损伤模型,在S9活化状态下分别以10-100μmol/L B(a)P处理细胞3h收获细胞或再恢复24h,用碱性单细胞凝胶电泳(comet assay)鉴定DNA损伤和修复情况,免疫印迹(Western blot)方法检测JWA和hsp70的表达水平。
4.Methods The mixture of 2BS cells (or lymphocytes) and 1% LMA is put on the gel of 0. 5% NMA. After breakage, electrophoresis and stain, the comet tail distance and comet tail area of 100 cells (per sample) are analyzed with Leica image analysis system.
方法将2BS或淋巴细胞悬液与1%低熔点琼脂糖(LMA)等体积混合,铺于0.5%正常熔点琼脂糖(NMA)胶面上,细胞经充分裂解、电泳、PI染色后,用Leica图象分析系统每样本分析100个细胞彗距和彗尾面积。
5.②performing verification experiment by Comet Assay(CA) testing DNA damage and FCM detecting the rate of apoptosis to clear activated AHRcan enhance benzene induced myetoxicity or not. The result manifest BP+BZ group had no significant enhance the apoptotic rate, comet tail length and percentage of tail cells contrasting to the BP alone group (P>0.05). ?
②以细胞凋亡率及彗星试验检测的彗星尾长及损伤细胞率作为骨髓细胞的毒效应指标来验证AHR活化与苯致骨髓毒作用的关系,结果显示经苯并(a)芘活化的染苯组与单独染苯组比较细胞凋亡率和彗星尾长及损伤细胞率均没有统计学意义(P>0.05)。

9.Explanation: Comet McNaught, the Great Comet of 2007, has grown a long and filamentary tail.
说明:2007年的大彗星,麦克诺特彗星,最近长出了一条长长的丝状尾巴。
10.14h UTC, Sept.23, I discovered a faint Kreutz comet in LASCO C3, and it was confirmed after one hour. If no accident, it will be my first SOHO-comet.
23日晚10时,我在C3中独立发现的暗淡克鲁兹族彗星在一小时后被确认。如果不出意外,它将成为我的第一颗拥有发现权的SOHO彗星。
