Using Web resources to construct multilingual medical thesaurus for cross-language medical information retrieval

Due to the language barrier, non-English users are unable to retrieve the most updated medical information from the U.S. authoritative medical websites, such as PubMed and MedlinePlus. However, currently, there is no any cross-language medical information retrieval (CLMIR) system that can help Chinese-speaking consumers cross the language barrier in finding useful English medical information. A few CLMIR systems utilize MeSH (Medical Subject Headings) to help overcome the language barrier. Unfortunately, the traditional Chinese version of MeSH is currently unavailable.In this paper, we employ a semi-automatic term translation method to construct a Chinese–English MeSH by exploiting abundant multilingual Web resources, including Web anchor texts and search–result pages. Through this method, we have developed a Chinese–English Mesh Compilation System to assist knowledge engineers in compiling a Chinese–English medical thesaurus with more than 19,000 entries. Furthermore, this thesaurus has been used to develop a prototypical system for cross-language medical information retrieval, MMODE, which can help consumers retrieve top-quality English medical information using Chinese terms.

新型迷宫式气锚及其应用

新型迷宫式气锚将重力分离原理和离心分离原理有机地结合在一起，其基本型气锚主要由上、下两级组成。上级为离心式螺旋气锚，下级为重力分离式和离心分离式综合气锚，可使油气流经同一长度锚筒时，达到双倍的分离效果。可根据油井气量的大小（气液比值）组成任意级数，实现油气的高效分离。还可对低产能井、沉没度易出现负值的油井进行油气分离，维持油井一定时间的生产。现场28口井的应用表明，新型迷宫式气锚油气分离效果理想，能有效地提高泵效，平均泵效由原来的28．9％提高到43．8％。     

高效防气防砂一体化管柱的研制与应用

为解决文南油田高气液比井出砂易造成卡泵的问题,研制了高效防气防砂一体化管柱。该管柱主要由闭式气锚、重力式防气装置和激光割缝筛管3部分组成。闭式气锚的分离作用消除了气体对抽油泵的影响,提高了泵效;重力防气装置利用液气分离原理和高烟囱原理进行液气分离,液流回流时间可达10min,排气最高压差可达0.2MPa;经激光割缝筛管过滤后的液体含砂粒外径小于0.05mm。该管柱在文南油田现场应用16井次,累计增液6000t,增油2717t,平均单井泵效提高7%。
