2003年5月4日新疆伽师-岳普湖5.8级地震烈度分布及建筑物结构破坏特点

新疆伽师-岳普湖5．8级地震宏观震中位于岳普湖县的铁热木乡和兵团农三师42团的北面，震中烈度为Ⅶ度。本次地震影响范围位于巴楚-伽师6．8级地震Ⅵ-Ⅶ度影响区域内，累计破坏效应造成了较为严重的房屋破坏。通过对大量震害资料和强震记录的分析，根据建筑物的破坏情况和场地峰值加速度衰减特征，在尽可能排除累计破坏效应的基础上确定了地震烈度分布，分析了不同烈度区中的建筑物结构破坏特点及其与地震动影响场的关系。     

山西临汾中心地震台地倾斜震前异常变化特征

从原始记录和分量图两方面对山西临汾中心地震台1991年以来的倾斜资料进行了分析，研究了临汾中心地震台地倾斜与省内及周边地区发生的中强地震的关系。结果表明，对1996年至2002年内发生的几次中强地震，临汾中心地震台地倾斜资料都有较好的异常反映。     

Seismotectonic environment of occurring the February 3, 1996 Lijiang M=7.0 earthquake, Yunnan Province

Introduction The surface rupture and aftershocks of the February 3, 1996 Lijiang earthquake are basically distributed along the N-S-trending Lijiang-Daju fault, which is boundary fault between Lijiang Quaternary, fault controlled basin and Yulong-Haba range (ZHANG, et al, 1997). Corresponding to the surface geological features, the focal rupture of the Lijiang earthquake also shows large component of dip-slip. It is of great difference from that of other earthquakes in west Yunnan, in w…

利用Cole-Cole模型组合得到SIP真参数的联合频谱最优化反演

利用Cole-Cole模型组合和稀释系数理论，可以描述测量得到的视复电阻率频谱与地下多个电性体SIP真参数之间的正演关系。本利用此正演关系进行反演试算，并比较了几种Cole-Cole模型反演方案的效果；提出固定极化目标体和围岩体的极化率同时反演其它各SIP真参数的反演方案。结果表明在固定极化率为真值时，利用此反演方案可以稳定、准确、快速地得出地下电性体SIP真参数。     

VICARIOUS RADIOMETRIC CALIBRATION OF SATELLITE FY-ID SENSORS AT VISIBLE AND NEAR INFRARED CHANNELS

For the problem of in-flight test site radiometric calibration for the FY-1D Meteorological Satellite onboard sensor's visible and near infrared channels,this paper described the calibration method,satellite-ground synchronous observation data acquired at China Dunhuang Calibration Test Site,parameter derivation and radiative transfer computation during the calibration,and the calibration result analysis.At FY-1D seven channels (with central wavelength at Channels 1:630 nm,2:865 nm;6:1610 nm;7:455 nm,8:505 nm;9:555 nm;10:932 nm),calibration coefficients obtained during the ground site calibration were compared with that respectively of prelaunch calibration.It is demonstrated that results of FY-1D onboard two sensors' (A and B) at channels 1,2,6 and 10 were close to pre-calibration,and the absolute difference of Gobi desert reflectance computed using test site and pre-launch calibration coefficients was no more than 2%. At other channels,large pre-launch calibration errors resulted in a poor consistency between the test site and pre-launch calibration.The errors can be corrected by the test site calibration results. Based on a rough estimation,the overall error of the calibration was about 6%. The paper also presented the in-flight vicarious calibration at the visible and near infrared channels of FY-1C sensor A which was launched in 1999 and has been put into operational mode since 2002.The results exhibit that FY-1C sensor's response has 23% attenuation at Channels 7 and 8,while only minor degradation at the other channels was found. During the mission,calibrations were also conducted at NOAA-17's Channels 1 and 2 (1:430-830 nm,2:500-1072 nm).A very good consistency has been achieved between the test site and pre-launched calibration results.     

应力调制在辽宁地区地震预报中的应用

应用应力调制图像法对辽宁地区1970年以来的21次ML≥5．0地震进行了检验。结果显示，有18次地震的震前出现了S值异常单元，虚报地震11次，漏报3次，R值评分0．58。     

地震应力触发数值模拟的初步研究

本文基于有限元方法，初步建立了西南地区二维和三维数值模拟有限元模型，并针对川滇地区，重点建立了包括上地壳、下地壳、上地幔等的三维有限元模型。最后，讨论了地震产生的应力变化对整个西南地区的应力调整情况。结果表明：前一地震对后续地震有一定的触发作用。因此，强震活动有限元模型的建立对判定未来强震危险区有一定的作用。

川陕丁家林金矿区探矿权的评估

为准确、客观估价丁家林金矿区探矿权价值，根据矿区地质报告中提交的储量级别、矿体控制程度和工程质量，确定了基础和可采储量、生产规模、矿山服务年限、贴现率、有关实物工作量等6项参数。综合运用贴现现金流量和重置成本法对探矿权进行评估，对达到详查程度的基础储量采用贴现现金流量法，控制程度低的资源量采用重置成本法，二者之和综合反映探矿权的价值。此方法适用于地质工作程度不均衡矿区的探矿权评估，贴现现金流量法要充分考虑储量的可信度和获利临界品位．重置成本法关键是准确确定有关的实物工作量。
