Abstract: 为了有效地对煤层气排采期间水文地质动态变化规律进行监测,以潘庄区块为研究对象,利用瞬变电磁探测技术对3号煤层排采井PE-055附近的地下水进行探测,探讨垂直煤层气排采井地下水的运移规律。结果显示,煤层气井排采降压过程会使地下水的存储和水力联系发生动态变化,瞬变电磁探测技术能够较好监测地下水运移特征,表现为视电阻率和水力联系的同步变化具有较好的耦合性。在地下水连通性差的区域,排采后视电阻率具有升高趋势;而在地下水连通性较好区域,视电阻率明显降低;视电阻率的动态变化不仅反映储层改造前后的差异性,而且指示出煤层气井排采期间地下水的运移方向,试验结果为煤层气开发期间的地下水运移监测提供了新思路和技术。

Abstract: 通过对东天山觉罗塔格一带晚古生代岩浆岩地质特征、岩石化学特征等系统研究, 认为该晚古生代岩浆岩主要由早石炭世至中二叠世的火山岩和侵入岩组成, 其形成与康古尔洋向北俯冲有关。早石炭世岩浆岩为康古尔洋初始俯冲而成的钙碱性岛弧火山岩及具有低压、低温特征的高钾钙碱性I型花岗岩;晚石炭世岩浆岩为后碰撞弧火山岩;早二叠世岩浆岩为具有后碰撞弧和板内双重特征的火山岩及高温、高压特征的I型花岗岩;中二叠世发育具有低压、高温特征的高钾钙碱性A型花岗岩。综合前人资料及本文研究成果, 初步认为觉罗塔格一带晚古生代经历了俯冲碰撞—碰撞造山—造山后陆内伸展的构造演化过程。

Abstract: 摘要: 根据主量元素、微量元素和Sr-Nd同位素地球化学研究结果,觉罗塔格构造带中企鹅山群火山岩企鹅山群火山岩分为拉斑玄武岩和钙碱性玄武岩,拉斑玄武岩和钙碱性玄武岩均具有高铝、低钛和相对富集轻稀土元素(LREE)、大离子亲石元素的特征,与典型的岛弧玄武岩相似。钙碱性玄武岩具有显著的Eu的负异常,其不相容元素含量显著高于拉斑玄武岩,在La/Sm-La图解中,钙碱性玄武岩为结晶分异作用的产物,拉斑玄武岩则为平衡部分熔融的产物。Sr-Nd同位素特征表明企鹅山群火山岩源自亏损地幔。在玄武岩构造环境判别图中样品均落入岛弧玄武岩范围内。通过综合该区岩石组合特征、地球化学特征、地球物理特征,认为企鹅山群为康古尔洋壳向北俯冲在大南湖岛弧南侧形成的石炭纪岛弧火山岩。
Abstract: Based on the geochemical data including major elements, trace elements and Sr-Nd isotopes of the volcanics from Qi’eshan Group occurring in the Jueluotage tectonic belt in eastern Tianshan, the volcanic rocks can be divided into theoleiitic series and calc-alkaline series. All of these volcanics show relative enrichment in aluminium, LREE, LILE and depletion in titanium. The calc-alkaline basalt has a characteristic of Eu anomalies, and the contents of incompatible trace elements are higher than those of the tholeiite basalt. The calc-alkaline basalt is the product of crystallization differentiation, and the tholeiite basalt is the product of partial melting from the La/Sm-La diagram. Initial Sr and Nd isotopic compositions show that the basalts from the Qi’eshan Group are derived from depleted mantle. In the discrimination diagram, samples from the Qi’eshan Group are plotted in the field of island arc basalt. The characteristics of the rock combination, geophysics, geochemistry,and the results of previous studies suggest that Qi’eshan Group formed in Dananhu island arc setting owing to the northward subduction of the Kanggur ocean

Abstract: 摘要:目的 探讨成人大骨节病患者年龄、Kellgren-Lawrence分级(K-L分级)、Wiberg分型与髌骨稳定性之间的相关性。方法 横断面调查甘肃省岷县店村镇柏柳村、折庄村、建村成人大骨节病例143例,每位患者均拍摄数字化X线摄影(DR)膝关节正侧位片、髌骨轴位片,依据DR X线片测量Insall指数、外侧髌股角、沟角、适合角、髌骨外移率、髌股指数等髌骨稳定性相关参数;同时根据髌骨Wiberg 分型结果将患者分为4组,根据临床KBD分度将患者分为3组,并对组间髌骨形态学参数进行单因素及多因素方差分析;应用Spearman检验分析髌骨Wiberg分型、临床KBD分度、影像学K-L分级三者与髌骨稳定性的相关性。结果 ①髌骨Wiberg 分型单因素方差分析(ANOVA)结果显示,外侧髌股角随着髌骨分型级数的增加而减小,适合角、髌骨外移率、髌股指数随着髌骨分型级数的增加而增大,6个参数P均<0.05,即表示这种增加或减小的组间差异有统计学意义;KBD临床分度的ANOVA检验结果示,外侧髌股角随着临床分度增大而减小,而适合角、沟角、髌骨外移率、髌股指数随着临床分度增加而增大,除Insall指数P>0.05外,其余5个参数P均<0.05,即表示这种增加或减小的组间总体差异有统计学意义。②Spearman检验显示:Wiberg分型与外侧髌股角、适合角、髌骨外移率、髌股指数呈强相关(R=0.752、0.582、0.533、0.735,P<0.05);与年龄、K-L分级无相关性(R=0.024、0.030,P>0.05)。K-L分级与年龄呈强相关(R=0.782,P<0.05);与其它参数均无相关性(P>0.05)。年龄与K-L分级、外侧髌股角呈强相关(R=0.782,0.506,P<0.05);与Wiberg分型、Insall指数不相关(R=0.024、0.053,P>0.05);与适合角、髌骨外移率、髌股指数均呈中度相关(R=0.403、0.361、0.475,P<0.05)。结论 髌骨Wiberg分型是影响髌骨稳定性的重要因素,年龄对髌骨稳定性也有一定影响;K-L分级不影响髌骨稳定性。
ABSTRACT: Objective To study the correlation of patellar stability with age, knee Kellgren-Lawrence grading and patellar Wiberg typing of adults with Kaschin-Beck disease (KBD). Methods Through cross-sectional study, we asked 143 adult patients with KBD from several villages in Gansu Province to receive digital radiographic x-ray (DR) which included lateral slice of knee joint and axis slice of patellar. Meanwhile, each patient had to undergo patellar stability measurement on the DR film which included some indexes such as Insall index, lateral patellofemoral angle, sulcus angle, congruence angle, lateral migrating ratio of patella, and patellofemoral index. Then, all the participants were divided into four groups based on the patella Wiberg typing and three groups based on KBD clinical grading. Last, we analyzed the correlation of patellar stability with patellar Wiberg typing, clinical KBD grading, and Kellgren-Lawrence grading of the patients by Spearman test. Results ① By ANOVA test on the patella Wiberg typing, lateral patellofemoral angle decreased with increased level of patella Wiberg typing, but congruence angle, lateral migrating ratio of patella, and patellofemoral index were increased with increased level of patella Wiberg typing. P values of the six indexes were all <0.05, which indicated that these differences between groups were significant. By ANOVA test on the KBD clinical grading, lateral patellofemoral angle decreased with increased level of KBD clinical grading, but congruence angle, lateral migrating ratio of patella, sulcus angle, and patellofemoral index increased with increased level of KBD clinical

Through analyzing the problems in the work of managing land surveying and mapping, based on the work of land and resources, the role of land surveying and mapping was confirmed, so as to establish the land surveying and mapping management method using project management. On this basis, the framework and database organization of the information system of managing land surveying and mapping with C/S structure were designed. This paper developed the information system of managing land surveying and mapping, which synthesized the project management, da-tabase management, process management and application tools, based on the Oracle 10g Standard Edition database platform as well as ArcEngine and ArcSDE geographic information platform by adopting Visual Studio2008. The system achieved good results through actual application.
