地地震多参数BP神经网络预测煤层厚度

依据煤层反射波运动学和动力学特征，提取出了波峰波谷振幅A1、平均频率Fa、主频带能量Qf1、低频带宽能量Qf和峰值频率Fmain等5个地地震特征参数。选取8组学习样本，利用4层BP（Back Propagation)人工神经网络模型，采用动量法和自适应调整的改进算法，训练BP网络，用训练好的BP网络预测煤层厚度。经实例验证，地震多参数BP网络预测煤层厚度精度高，是一种有效的煤厚预测方法。     

三维相干切片断层多边形检测

作者在本文中将三维切片视为二维图像，利用图像边缘检测技术，检测出相干切片上断层多边形，并将其直接投影到测网底图上，用于构造成图。该项技术不仅提高了用相干切片解释断层的精度，而且提高了断层解释效率，使相干数据体技术在三维解释中的作用得到更大的发挥。实际应用表明，三维相干切片断层多边形检测技术，是全三维高精度解释的有力工具，提高了解释效率，缩短了解释周期。

The wavelets and hierarchies of the climate system

Summary Wavelet analysis of global mean temperature data, the drought-flood data of the past 500 years in China, and the temperature time series of Shanghai, highlights the following: (1) the climatic wavelets depend on the hierarchies of a climate system; (2) for different time scales or hierarchies, a climate system may have different catastrophic points and periods; (3) for different time scales or hierarchies, variation of the Southern Hemisphere temperature has an obvious phase-lag compared with that of the Northern Hemisphere and the catastrophe points also lag behind; (4) in a cold-warm period, the cold semi-period of the Northern Hemisphere is obviously longer than the warm one; (5) for different hierarchies or time scales, there exists a phase-lag for the droughtflood variation in China moving gradually with latitude from north to south. Finally, a new technique of climate diagnosis, the phase curve of wavelets, is put forward in this paper.With 6 FiguresSupported by Chinese NKPFR.     

中国桐柏大别构造带变质演化的岩石学证迹

桐柏大别构造带是秦岭造山带的东延部分，经历过多期次不同体制的构造运动，现今的桐柏大别山区是由一系列变质地体拼合而成，地体与地体之间为断层或韧性剪切带所围限各地体有自身变质变形史和PTt轨迹，但却有着碰撞造山带所共有的后造山抬升过程。本文揭示了随县群、红安岩群及大别杂岩中柯石英榴辉石、蓝晶铝直闪石片岩及紫苏石榴黑云母片麻岩的退变质再平衡结构特点。报道了大别山麻粒岩相变质年龄为1699Ma。各类岩石减压退变质再平衡结构，标志着后造山的隆升过程及其对桐柏大别构造带变质演化的启示。

High-Pressure and Ultrahigh-Pressure Metamorphic Belt in Tongbai-Dabie Mountains,Central China

There are four units of high-pressure to ultrahigh-pressure metamorphism extending from south to north across the Tongbai-Dabie Mountains: the epidote-blueschist-facies unit, the low-temperature eclogite facies unit , the ultrahigh-pressure eclngite facies unit and the medium-temperature eclogite facies unit . The later two units were formed during the Caledonian subduction between the Tongbai-Dabie microplate and the North China plate ,the former two units are the products of Indosinian continental-continental subduction and collision between the Yangtze and the North China plates.
