陆面温度反演算法——劈窗算法的敏感度分析

劈窗算法是目前由热红外遥感图像数据获取陆面温度最主要的方法。由于进行地面像元尺度实时陆面温度同步测量的困难,尚无法直接对现有各劈窗算法进行评判。该文借助于辐射传输模型ＬＯＷＴＲＡＮ－７及其提供的６种标准大气模式,进行模拟计算,分析了６种主要劈窗算法对大气廓线误差和比辐射率的敏感度,作为劈窗算法适用性的一间接判据。     

Study on automatic recognition of the first motion in a seismic event

IntroductionSeismic detection is one of the most effective methods to monitor underground explosions. When an underground explosion is conducted, like an earthquake, it will radiate seismic waves. Stimulating from sources, these seismic waves travel through the Earth(s interior and surface, propagating widespread. These waves can be recorded by seismograph systems on surface. By studying the recorded seismic signals, we can obtain much detailed information on such a seismic event. We can the…     

沉积物中石英E'心的热力学特性及其地质应用意义

对 8个取自南海珠江口盆地XJ33-2 -1井的样品进行了热力学实验 ,使用电子自旋共振 (ESR)技术获取了样品中石英E′心天然状况下的ESR信号强度I1对经热活化技术处理后石英E′心的ESR信号强度I2 的比值。实验结果表明 :每个样品的活化温度不完全相同 ,这与母岩的特性有关 ;I1/I2 值与古地温呈正相关关系 ;I1/I2 值与地层年龄有很强的相关性 ,相关系数高达0 .99。说明I1/I2 值具有古地温指示和地质计时的实际意义。     

大陆岩石圈有效弹性厚度研究综述

大陆岩石圈有效弹性厚度（Ｔｅ）是表示岩石圈抵抗挠曲变形能力的参数。通过计算该参数,可以获得不同地区、不同构造省的岩石圈挠曲强度,并可以进行区域的比较。本文详细地介绍了Ｔｅ的计算方法、研究模型和控制因素。由于Ｔｅ与岩石圈热结构、流变结构、力学结构紧密相关,Ｔｅ的研究不仅有助于岩石圈强度的定量认识,而且可以获取岩石圈热结构、力学结构空间变化的信息,以及对地幔对流等动力学问题做出制约。     

就XS—02井压裂情况谈煤层气井完井及增产措施

在对XS-02井完井压裂进行总结的基础上,分析了3种完井方式和3种压裂液在煤层气井中的适应性,结合XS-02井压裂施工的具体情况,解释煤层气井压裂时高滤失和高施工压力的原因,为以后各井的工作提供可参考的依据。      

Formation of the Devonian Fengtai Hydrothermal Brine Basin and the Metallogeny of Gold and Lead-Zinc Mineralizations in Shaanxi

The study of the relationships between the hydrothermal sedimentary formations and the gold andlead-zinc mineralizations in the Devonian Fengtai basin in Shaanxi shows that there was a hydrothermal brine sedimentary event which was inserted into the normal sedimentary background from the late Middle Devonian to the early Late Devonian. This event is closely related to gold and lead-zinc mineralizations in this area.
