Monitoring the sandstorm during spring season 2002 and desertification in northern China using SSM/I data and Getis statistics

A massive sandstorm enveloped most part of northern China during the spring season 2002. Monitoring the evolution of sandstorm and desertification has become one of the most serious problems for China's environment. Since 1989, one of the most advanced and operational passive microwave sensors is the DMSP SSM/I (special sensor microwave imager) operated at seven channels (19, 37, 85 GHz with the vertical and horizontal polarization and 22 GHz with vertical polarization only). In this paper, the sandstorm and desertification indexes, SDI and DI, are derived from the radiative transfer equation, and are employed with multi-channel measurements of the DMSP SSM/I for monitoring the sandstorm and desertification in northern China. Some SSM/I data in 1997 and 2001 are employed. The algorithm of Getis statistics is developed to categorize the spatial correlation and its evolution these days. It is demonstrated that the SSM/I indexes, SDI and DI, and its Getis statistics are well applicable for monitoring the sandstorm and desertification.     

Experimental Observables on Nuclear Liquid Gas Phase Transition

Progress on nuclear liquid gas phase transition （LGPT） or critical behavior has been simply reviewed and some signals of LGPT in heavy ion collisions, especially in NIMROD data, are focused. These signals include the power-law charge distribution, the largest fluctuation of the fragment observables, the nuclear Zipf law, caloric curve and critical exponent analysis etc.     

《淮南万毕术》夏造冰之新解——兼与厚宇德先生商榷

二十多年来学术界关于《淮南万毕术》“夏造冰”问题的讨论颇具戏剧性．1983年洪震襄否定了这种可能性，十年之后李志超、赵虹君的相关研究得出了相反的结果．2004年厚宇德研究了李、赵肯定说实验方案，得到出乎意料的相反结论．本文根据原文提出一个新的技术思路，按此思路，则有可能实现“夏造冰”．实际操作中能不能达到预想的目标，还有待于实验验证．
