基于神经网络的降雨径流预报

本文将人工神经网络应用于二滩水电站以上支流鱼河的降雨径流预报，通过建模、计算、比较和分析可知，其非线性映射能力、自学习能力和灵活性，均能较好地反映降雨径流之间的非线性的、复杂的转换关系，结合流域水文特性并合理处理建模数据，值得进一步深入研究。

2006年SEG年会反映的各向异性研究新进展

介绍了2006年SEG年会上所反映的各向异性研究的新进展，主要包括：提高速度分析精度的各向异性速度分析参数正交化方法；影响裂隙储层预测的地震波动力学与运动学特征差异分析；验证现行裂隙硬币理论模型可靠性的不规则裂隙有效弹性参数计算分析；提高计算效率的波场延拓各向异性参数参考值优选Lloyd算法；常见TTI介质不同成像方法试验效果的比较。     

全球气候变暖对水资源的影响

全球气候变暖加剧了干旱、洪涝、台风等自然灾害的发生，是目前各国政府和社会公众普遍关注的热点问题。根据有关资料对气候变暖研究进展情况作相关介绍，可供参考。     

80年代黄河中游来沙减少的原因分析

80年代黄河中游来沙量减少,主要原因是降雨量减少和降雨强度减小,流域综合治理也起到了减沙作用。据分析,降雨因素减沙约占总减沙量的70％,流域综合治理减沙约占30％。     

降雨衰减对移动卫星系统通信的影响及补偿

针对移动卫星系统的特点，分析了降雨引起的信号衰减的原因，给出了雨衰的计算方法。Ka波段一般用于移动通信业务，从分析结果上看该波段信号受降雨影响较大。提出几种补偿雨衰的方法，给出了上行功率控制法的系统原理图。     

从76届SEG年会看综合物化探技术的发展方向

文中在介绍76届SEG年会的展商、展台及会场专题报告与论文发布情况的基础上，阐述了参加本届SEG年会的体会，指出了重磁电技术发展的四个趋势：向海洋勘探技术方向发展、向复杂区综合勘探技术方向发展、向三维联合处理和三维可视化解释技术发展、向直接圈定和检测油气方向发展。     

Evaluation of rainfall networks using entropy: II. Application

This paper, the second in the series, applies the entropy approach to space and time evaluation of rainfall networks in Louisiana. The evaluation is made for five sampling intervals: daily, 2-day, weekly, monthly, and yearly, and for two separate seasons. In each case, the best combination of raingages is suggested and the lines of equal information (isoinformation contours) are constructed showing the areas of greater or less information transfer. The isoinformation lines are especially suitable in decisions concerning the expansion of the existing network or deleting the unnecessary raingages.     

水利工程排涝减灾效益分析与计算

在分析涝灾成因特点基础上对涝灾进行了重新定义，在研究涝灾损失及 排涝效益时引入了临界降雨量的概念，从而奠定了水利工程排涝减灾效益分析与计算的理论基础，并给了效益计算的一般计算模型。
