岩石弹脆性分维损伤本构模型

本文定义岩石构元中破裂面的分维值为各向同性损伤变量,而各个方向上裂纹面的累加量定义为各向异性损伤变量,并根据裂纹发育特征提出了损伤变量演化方程,从而建立起岩石脆性变形破坏过程的分维损伤本构模型。最后,利用该模型对大理岩单轴压缩应力应变曲线进行了模拟,结果说明本文提出的模型是较为合理的。     

碳酸锰氧化实验和热力学分析

通过对碳酸锰氧化实验的结果分析和讨论，建立了一种适合于锰氧化过程的非平衡热力学模型，并利用此模型对硫酸锰氧化过程作了热力学可行性分析，研究结果表明，碳酸锰氧化过程是矿物组合的变化过程，也是锰自身价态的转为过程，整个过程既存在平衡状态，又存在非平衡状态，是一个不可逆的，多相的复杂反应。     

Tectonic Evolution of the Himalayan Collision Belt

This paper discusses the tectonic divisions of the Himalayan collision belt anddeals with the tectonic evolution of the collision belt in the context of crustal accretion in thefront of the collision belt, deep diapirism and thermal-uplift extension and deep material flow-ing of the lithosphere-backflowing. Finally it proposes a model of the tectonic evolution-progressive intracontinental deformation model-of the Himalayan belt.

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。     

AN APPARENT TEMPERATURE MODEL BASED ON THERMAL EQUILIBRIUM

In this paper,a comprehensive analysis and review of the advances in the research of human body comfort degree is made.Based on the studies of human thermal equilibrium theories contributed by previous researchers,different apparent temperature models corresponding to different environments are set up in accordance with the current situation and the characteristics of metabolism in different groups of people in China.After case studies and comparison with present dominant human body comfort degree statistical models,it is proved that the apparent temperature models have high rationality and wide adaptability.Furthermore,the comfort scaling standard according to apparent temperature is suggested,which is suitable for the middle latitude regions in China.
