Research on the Application of Residual Apparent Polarization to Surveying Deep Jiaojia-type Gold Mines

The theory and equations of the residual apparent polarization method are proposed and described in this article. Based on studies of existing mines, the residual apparent polarization ηα^sy, calculated from the induced-current middle-gradient apparent polarizations ηα^sy at large and small electrode spaces over the known deep Jiaojia-type gold mines, have been shown to separate the effects of mines from the anomalous polarizations generated from the strongly altered rocks in fracture zones.     

地壳形变观测与地震前兆一般性问题的讨论

从构造变形及破裂成核的角度来看, 强地震前形变异常理应出现在地震震源附近, 而许多连续形变观测事实与这种认识往往是相矛盾的.本文研究了攀枝花多次形变异常结束后10天内的首发中强地震与异常之间的相关性, 发现西北地区2000-2005年5.9级以上地震震中(绝大多数作为异常后的首发地震)分布具有较好的规律性.本文揭示的事实对于认识形变观测与前兆本质、实验场区连续形变观测台网建设及物理预测方法探索等都提供了新的可能性.

一次强雷暴过程的闪电特征分析

对2006年6月25日焦作地区强雷暴天气分析表明，东北低涡后部西北急流出口区与地面冷锋的耦合是造成本次过程的直接影响系统。针对该过程伴随的强烈闪电现象，通过研究卫星云图和雷达回波特征，结合XDD03A型闪电定位仪对闪电过程的重现，探索强雷暴天气形势下对流云不同部位的闪电分布以及雷暴不同生命期所对应天气现象的闪电分布特征。     

机载InSAR测绘系统飞行试验报告

干涉合成孔径雷达测量技术是近年来发展起来的一种新技术。机载InSAR测绘系统在国内还处在研制阶段。其测绘能力以及测图精度以前只能从外文资料中了解。为了获取机载InShR测绘系统第一手资料。我们在河北某地进行了机载InsAR测绘飞行试验，并对InSAR数据进行了处理，对其测绘能力以及测图精度进行了分析，给出了试验结论。     

A simple hydrophobicity-based approach to predict the toxicity of unknown organic micropollutant mixtures in marine water

In this study, we propose a simple hydrophobicity-based approach to predict the toxicity of mixtures of marine organic micropollutants. Fifty mixtures were chosen, comprising individual chemicals randomly chosen from three halogenated benzenes, three phenols, two petroleum hydrocarbons, three polychlorinated biphenyls (PCBs), four organochlorine pesticides (OCPs) and two herbicides, with the intention of simulating the mixtures of organic micropollutants that may exist in some marine waters. The hydrophobicity of the mixtures was quantified by measuring the C(18)-Empore(TM) disk/water partition coefficients (K(MD)). A K(MD)-based approach was proposed to describe their toxicity to Photobacterium phosphoreum, and the application of this approach to another 10 related mixtures proved its predictive capability, as indicated by the consistency between the predicted and observed toxicities (r(2)=0.905, SE=0.101, and F=76.325 at P<0.001). This predictive capability convinces us that the K(MD)-based approach provides a general approach to predicting the toxicity of mixtures of organic micropollutants in marine water.     

“Suspending village” a model of new development area in the ningxia hui autonomous region of China

The southern part of the Ningxia Hui Autonomous Region in China was infamous for its poverty and serious soil erosion caused by over population. In order to alleviate poverty and backwardness, a plan was worked out: to remove 200,000 people to the north plain by developing newly irrigated land during the period of 1983–1992. The plan has been in operation for eight and half years to date. About 200,000 people have been removed from the poor southern part to the newly developed area, and 800,000 mu (1/ 15 ha) of desert land has been cultivated. Most of the migrants have been lifted out of poverty and the people ’s life in the south is being improved. During the immigration process, a model, called “Suspending Village”, has been developed. In the article, the whole process of the development and the strategies are discussed.

现代地理空间决策

这是一篇有关理论地理学的基础研究。在地理空间决策范畴中,讨论有限的资源以及产生的效益,如何在不同地理位置上的合理分配,是地理学家一直在追求的基本目标之一。本文以空间行为理论为出发点,在马尔可夫原则下,结合地理空间的特点,阐述了“转移概率过程”的局限,发展了更加接近于实际状况的理论范式,并且以“斜截形式”、“得失形式”、“固点形式”作出了解析,从而完成了“地理时空耦合”的深刻表达。下一步,将是在实际应用中取得验证和订正。
