Methods The present study is a randomized comparative clinical trial. 607 healthy parous women were randomly allocated into GyneFix IN group (n=302) or TCu 380A group (n=305). IUD was inserted during the menstrual interval by the trained investigators. Follow-up were arranged at 1,3,6 and 12 months after insertion. The discontinuation rates were calculated by life table method.

采用随机对比性多中心临床研究方法，对607例健康经产妇女由经过培训的专人以随机方法于月经间期放置GyneFix IN IUD 320例(GyneFix IN组)及TCu 380A IUD 305例(TCu 380A组)，于放器后1、3、6和12个月随访，以生命表法统计两种IUD的终止情况。

The dissertation is focus on establishing a user model for personalized information retrieval based on user partialness keyword list, including classified dictionary, study module, user behavior monitor module, Internet change detecting module, document analysis and information filtering module, and with the communications and collaboration of these modules, the model obtains on load of user partialness information while in inquiring, retrieving and results filtering. Thus the precision of information retrieval increases, and it can keep up with the change of webpage, and personalized information retrieval service realized.

Especially, it is found that there exists three types of relative permeability of water such as concave, convex to the water saturation ax and the reversed "S" pattern. The super-low permeability reservoir is sensitive to pressure, apparent with millipore undersaturation and water blocks. In this study, a new concept of irriducible undersaturation is brought up. And a new mode to describle the process of imbibition dynamics is used to reveal and confirm the mechanism of pinhole enveloping macropore as following: pendular ring of wetting phase gathers→it fills throat→it truncates nonwejting phase . The expression of pressure distribution and the equation of oil production are deduced under conditions of non-darcy linear seepage and non-linear seepage.

尤其发现水相相对渗透率曲线存在凹向、凸向含水饱和度轴及反S形三种形式；特低渗透储层的压力敏感性强，微孔隙的欠饱和及水锁效应显著，本文研究中提出欠束缚水饱和度的概念，引用一种描述渗吸动态即湿相液环聚集→充填喉道→截断非湿相的演化过程的新方法，更深刻地揭示和证明了&小孔包围大孔&机理；推导出了非达西线性渗流和非线性渗流条件下的压力分布表达式和油井产量方程。

In order to further understand the dependence of bioactivities on the structure of new fluorine-containing pesticidal compounds to build up significant ligand-receptor models, and to find out the pharmacophores of these analogues, 3D-QSAR analyses have been carried out with DISCO, CoMFA and Leapfrog approaches on the basis of our previous classical QSAR study. Firstly, the compounds were classified according to their structures.
