To resolve these problems, this paper deals with the technology of foamed acidizing. The anti-salt and anti-acid foamer DY-1+SJ-8 and foam stabilizer KMS-2 were selected, then their performance under different foamer concentration condition was evaluated and the proper concentration was determined. Thereafter the diversion experiment of foamed acid through the parallel core was conducted.

针对上述问题，对泡沫酸酸化技术进行了研究：通过室内实验筛选出了耐酸耐盐的起泡剂DY-1+SJ-8和稳泡剂KMS-2，并对不同起泡剂浓度下的泡沫酸性能进行了评价，确定了其使用浓度；在此基础上进行了泡沫的岩心分流实验，实验结果表明泡沫泡体可以增加低渗透岩心的分流量，减少高渗岩心的分流量，使泡沫流体在不同渗透率岩心内均匀推进。

Therefore,it is necessary to construct a lightweight Web framework that is equipped with low intrusiveness and able to make the J2EE platform technology in a coupling state.

因此，一个具有低侵入性的、能够让J2EE平台技术处于"松耦合"状态的、轻量级的Web框架是迫切需要的。

The results indicated that Kail/CD82 is higher expressed in HT29 and SW480 than in LoVo and HCT116 whatever in mRNA or protein level.The possible mechanism of down regulation of Kail was also analyzed. By PCR-SSCP,8 exons of Kail,exon 3 to exon 10,were screened in LoVo and HCT116 cell lines. The methylation of CpG islands in promoter region was analyzed,and the expression level of p53 was detected by IH and Western Blot.

为进一步探讨Kai1基因表达下调的机制，本研究用PCR-SSCP技术分析了Kai1／CD82表达较低的LoVo与HCT116细胞系的Kai1基因第3～10外显子是否存在点突变，检测Kai1基因启动子区域CpG岛的甲基化状况，并用免疫组化与Western Blot等方法研究Kai1基因表达与p53异常之间的相关性。

In home, because in the price and the technical reason, the ordinary electronic formula automobile security occupies the mainstream status, this kind of security product majority has the security function to be unitary, the reliability low, lacks flaws and so on monitoring function, therefore studies designs one kind of new effective automobile burglary protection system is very essential.

在国内，由于价格上和技术上的原因，普通的电子式汽车防盗器还是占据主流地位，这类防盗器产品大多数都存在着防盗功能单一、可靠性低、缺乏监控功能等缺陷，因此研究设计一种新型有效的汽车防盗系统是十分必要的大学论文网 www.wnwu.com 。

Based on the example in Min114 block at Xinmin oil field,the authors analyze the relation of the fracture and crustal stress,measure the direction and length of the hydraulic fracture by receiving the microseism signals when the terrene is broken,which provides a basis for deploying reasonable flood pattern for development of low permeability reservoir.
