EGS程序图形化输入平台的开发

为了使EGS能够更加方便地被工程人员使用，使用VC^ 语言开发出一套运行于Windows下的EGSWIN程序，其中包括一个图形化的输入平台，通过使用本程序，用户可以仅仅进行简单而直观的输入几何实体的工作，就可以实现区域的定义。极大的提高了EGS的使用效率。     

钠冷快堆中喷雾钠火的计算分析

根据钠冷快堆中喷雾钠火的特点建立了理论模型，编制了SSPRAY程序。该程序模拟钠喷雾燃料过程中钠滴的运动、钠和氧气的燃烧反应、热量传递和质量传递等瞬态过程。用该程序计算了气体和墙壁温度、气体压力、氧气摩尔份额、喷雾流燃烧速率和热量热递速率等主要参数。利用AI实验数据和美国SPRAY－3A的计算结果对程序进行了验证，结果符合较好。     

Has risk associated with smoking increased? Results from the Copenhagen Center for Prospective Population Studies

BACKGROUND: Two recent much cited publications have raised the concern that risk associated with cigarette smoking has so far been underestimated. In this study we wish to determine whether excess all-cause mortality associated with smoking has increased during the last 20-30 years in a study population representative of the general Danish population and whether any such changes relate to changes in smoking behaviour. METHODS: Pooled data from three prospective population studies conducted in Copenhagen with detailed information on smoking habits. A total of 31,194 subjects, 17,669 males and 13,525 females, initially examined between 1964 and 1992 with examinations repeated at intervals from 1-10 years, were followed until 1995 for all-cause mortality. Relative mortality risk in smokers versus never-smokers was calculated within periods of five calendar years and compared throughout the study period. RESULTS: Male smokers' exposure did not change during the study period whereas female smokers' exposure to tobacco increased in terms of age at smoking onset, quantity smoked and depth of inhalation. During follow-up 5744 males and 2900 females died. In males, death rate ratios (comparing continuous smokers with never-smokers) did not change in the study period. In females, ratios increased from 1964-1978 to 1979-1994 by a factor of 1.3 (95% confidence interval 1.0-1.8). CONCLUSIONS: In agreement with the observed changes in smoking habits, excess mortality in male smokers did not increase whereas excess mortality in female smokers increased slightly.     

不同灌溉条件下的水稻需水规律及水分生产率分析

稻田需水量包括植株蒸腾、棵间蒸发、田间渗漏3部分。研究表明，水稻在充分供水条件下所形成的蒸腾量中包含了一部分无效蒸腾，无效蒸腾量的减少不会影响作物的生长发育，反而会有不同程度的增产和优质效应。节水灌溉技术的推广产生了明显的经济与社会效益。结合当地实际情况采用3种常见的灌溉方式探讨了不同灌溉方式下水稻的需水规律、灌概定额和生产率的差异，为水稻节水高效栽培提供理论与技术依据。
