The sand body of channel in the middle sublacustrine fan has good porosity and is favorable reservoir.

利用东濮凹陷桥口地区的地质、测井和化验分析资料，从沉积微相、成岩作用、岩石结构等多方面入手，对其储层物性特征和控制因素进行了研究，指出桥口深层气藏湖底扇中扇辫状水道砂体物性较好，为有利储集层；该储层孔隙类型以次生溶蚀粒间孔隙为主，岩石粒度较细、分选中—差、以点—线接触为主；片状或弯片状喉道所占份额较大，造成储层低孔低渗；受溶蚀和交代作用的影响，部分层位次生孔隙发育，深层中也存在物性较好的储层。

The sulfamate moiety in the structure of topiramate is chemically related to known CA inhibitors, and in fact, topiramate inhibits CA activity. To further explore the pharmacological action of topiramate, and clarify the possibility of anti-tumor growth and metastasis of CA inhibitors and its relation with AQP1, we studied the effect of topiramate on adhesion of high metastatic prostate carcinoma to laminin, and established the spontaneous metastatic model of Lewis lung carcinoma to studied the influences of topiramate on tumor growth and metastasis and AQP1 expression in lungs and primary tumors of mice.

为了深入研究托吡酯的药理作用，阐明CA抑制剂和水通道蛋白AQP1相互作用影响肿瘤生长和转移的可能性及其机制，我们研究了托吡酯对高转移的前列腺癌细胞粘附于基质成分层粘连蛋白的影响；以Lewis肺癌自发性转移为模型，考察了托吡酯对肿瘤生长和转移的影响；同时观察了托吡酯对荷瘤小鼠肺组织及原发瘤组织AQP1表达的影响；检测了其对血管新生的作用；利用体外AQP1表达模型，研究了CA抑制剂对AQP1功能的影响；此外，用蛋白质组学的关键技术，通过对模型组与托吡酯治疗组血清蛋白质组的比较分析，来寻找与肿瘤转移相关的蛋白质，探索托吡酯的可能作用靶点。

In this paper the principle of substructure analysis of matrix displacement method is used to condense superstructural stiffness of tall building to the boundary stiffness of the foundation beams, the subsoil model of the layers summation procedure of finite compressible layer is introduced herein.
