加拿大东海岸冬季风暴的分析

利用加拿大大气环境局第二次冬季风暴观测（简称ＣＡＳＰⅡ）的部分资料，对加拿在东海岸冬季风暴的发生，发展情况进行了分析，结果表明，大多数风暴能达到爆发性发展程度，并对其中一个形成眼区的强风暴例子做了进一步讨论。     

Processing of oxidised nitrogen compounds by passage through winter-time orographic cloud

Four case studies are described, from a three-site field experiment in October/November 1991 using the Great Dun Fell flow-through reactor hill cap cloud in rural Northern England. Measurements of total odd-nitrogen nitrogen oxides (NO _y ) made on either side of the hill, before and after the air flowed through the cloud, showed that 10 to 50% of the NO _y , called NO _z , was neither NO nor NO₂. This NO _z failed to exhibit a diurnal variation and was often higher after passage through cloud than before. No evidence of conversion of NO _z to NO₃ ^- in cloud was found. A simple box model of gas-phase chemistry in air before it reached the cloud, including scavenging of NO₃ and N₂O₅ by aerosol of surface area proportional to the NO₂ mixing ratio, shows that NO₃ and N₂O₅ may build up in the boundary layer by night only if stable stratification insulates the air from emissions of NO. This may explain the lack of evidence for N₂O₅ forming NO₃ ^- in cloud under well-mixed conditions in 1991, in contrast with observations under stably stratified conditions during previous experiments when evidence of N₂O₅ was found. Inside the cloud, some variations in the calculated total atmospheric loading of HNO₂ and the cloud liquid water content were related to each other. Also, indications of conversion of NO _x to NO _z were found. To explain these observations, scavenging of NO _x and HNO₂ by cloud droplets and/or aqueous-phase oxidation of NO₂ ^- by nitrate radicals are considered. When cloud acidity was being produced by aqueous-phase oxidation of NO _x or SO₂, NO₃ ^- which had entered the cloud as aerosol particles was liberated as HNO₃ vapour. When no aqueous-phase production of acidity was occurring, the reverse, conversion of scavenged HNO₃ to particulate NO₃ ^-, was observed.     

地震破裂过程的几何学与运动学特征的模拟

本应用形变破裂和激光全息光弹实验，结合断裂力学的观点研究了地震破裂过程的三个方面：１．地震破裂的力学机制；２．地震破裂的应变特征与运动过程；３．地震破裂过程的应力场分布特征。并分析了地震破裂过程的几何学与运动学特征以及探讨了它们与地震发生。前兆和余震迁移的密切关系。此项研究为活动断层分段研究和地震预报提供了实验证据。

长江三角洲南部“大城市圈振兴”理论的质疑

工业发展和城市化的传统理论，对亚洲的某些具有较高生产力水平，且还在发展中的“大城市圈”不能充分地解释，本文对长江三角洲南部空间经济转为的“大城市圈振兴”理论进行了批判地评论，根据最新的现场调查结果，从根本上对“转为过程”的假说提出质疑，并且提出了更适当的的区域发展战略，此外还证明，关于亚洲大城市带的一般结论，必须建立在对地方性经济变革认识的基础之上。     

三峡库区经济发展评价

当前三峡库区经济发展存在主要产业经济效益低，国有产业亏损大，产业规模小，城镇经济中心作用弱等突出问题．库区开发必需是持久战和持续发展相结合，将库区基础设施建设放在重要地位，搞好资金、行业、所有制之间的优化组合，大力发展第三产业；要准备用几十年的艰苦奋斗，才能赶上全国平均水平．
