用VC6.0开发OLE DB Provider的技术

随着信息化时代的不断深入,信息处理和信息共享变得越来越重要,数据访问技术对于信息系统也就显得尤为重要。现今处理日常业务必需的大量的非常重要的信息,是在传统的数据库之外。ＵＤＡ（ＵｎｉｖｅｒｓａｌｄａｔａＡｃｃｅｓｓ）提供了应用程序对各种信息源的数据存储的统一访问。通过ＵＤＡ对某种数据源进行访问时,必须提供相应的ＯＬＥＤＢＰｒｏｖｉｄｅｒ本文论述了ＯＬＥ ＤＢ的基本概念,并结合实例说明如何用ＶＣ６．０ 开发ＯＬＥＤＢＰｒｏｖｉｄｅｒ。     

克拉玛依油田530井区下乌尔禾组地应力研究

利用岩心分析测定、测井解释、压裂过程分析和微地震波法等多种监测手段,研究了地应力及裂缝特征。结合地应力场的数值模拟工作,描述了地应力与裂缝的分布以及二者之间的关系。结合油井动态和分析还发现,地应力的大小与油气富集程度,尤其是单井初期产量,有较好的线性关系。克拉玛依油田八区530井区下乌尔禾组,水平主应力及主裂缝方向为东西向,中都低应力区为初期产量较高的部位。     

Overview of Human HtrA Family Proteases and Their Distinctive Physiological Roles and Unique Involvement in Diseases,Especially Cancer and Pregnancy Complications

The mammalian high temperature requirement A (HtrA) proteins are a family of evolutionarily conserved serine proteases, consisting of four homologs (HtrA1-4) that are involved in many cellular processes such as growth, unfolded protein stress response and programmed cell death. In humans, while HtrA1, 2 and 3 are widely expressed in multiple tissues with variable levels, HtrA4 expression is largely restricted to the placenta with the protein released into maternal circulation during pregnancy. This limited expression sets HtrA4 apart from the rest of the family. All four HtrAs are active proteases, and their specific cellular and physiological roles depend on tissue type. The dysregulation of HtrAs has been implicated in many human diseases such as cancer, arthritis, neurogenerative ailments and reproductive disorders. This review first discusses HtrAs broadly and then focuses on the current knowledge of key molecular characteristics of individual human HtrAs, their similarities and differences and their reported physiological functions. HtrAs in other species are also briefly mentioned in the context of understanding the human HtrAs. It then reviews the distinctive involvement of each HtrA in various human diseases, especially cancer and pregnancy complications. It is noteworthy that HtrA4 expression has not yet been reported in any primary tumour samples, suggesting an unlikely involvement of this HtrA in cancer. Collectively, we accentuate that a better understanding of tissue-specific regulation and distinctive physiological and pathological roles of each HtrA will improve our knowledge of many processes that are critical for human health.

煤矿立井过平顶山砂岩水害预注浆治理关键技术

工作面预注浆是立井过含水岩层主要水害防治方法之一。平顶山及周边煤田广泛发育的平顶山砂岩厚度一般在80～140 m,该层砂岩硬度较高,裂隙发育,但裂隙具有高倾角、微细、横向连通性差等特点,水害治理难度大。针对如平顶山砂岩这类含水岩层,采用分段注浆来保证整体注浆效果、多圈布孔避免残留注浆盲区、交叉环向螺旋布孔增强高倾角裂隙的连通性、水泥浆—化学浆联用保证微细裂隙的注浆扩散效果。该技术已在平煤十矿三水平进风井、十三矿己五采区进风井平顶山砂岩段水害预注浆治理等多个工程中应用,取得了理想的治理效果。较传统工作面注浆方式,在相对减少钻孔布置、节省工期及造价的同时,可保证治理效果,具有较高的实用性。
