开放微带不连续电路的三端口网络描述

给出了开放微带不连续电路的三端口网络描述。将微带电路向空间的辐射作为一个端口来处理，成功地消除了由于忽略电路的空间辐射效应引入的电路数字模拟误差。利用时域有限差分法（ＦＤＴＤ）一次运算就可得出三端口网络的Ｓ参数矩阵的各元素，而无需任何预处理，大大地节省了ＣＰＵ时间。实际计算与已发表的数据吻合得很好，表明文中给出的三端口定义是合理有效的。此三端口微带电路的定义可容易地推广到其他非屏蔽传输线电路的分析，可广泛用于电磁兼容分析、微带天线及其他开放传输线电路的ＣＡＤ技术中。     

Estimating the Risks of Smoking, Air Pollution, and Passive Smoke on Acute Respiratory Conditions

Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate.     

论转型期的社会失范与社会控制

自改革开放以来，我国进入了全新的快速转型期。社会转型是社会结构的整体性变迁，是社会由传统型向现代型的转变过程：而社会失范是转型社会的必然现象。正确认识这一点，对于我们把握社会转型和社会控制具有重要的方法论意义。

国际空难赔偿案件管辖权问题探究

随着航空运输迅速发展，国际空难赔偿案件日益增多，而每一起案件的解决都关系到管辖权问题。文章从区分国内空难案件与国际空难案件入手，对1929年华沙公约所规定的四种管辖权以及1999年蒙特利尔公约增加的第五种管辖权进行了分析，并在此基础上，探讨了中国法院确定国际空难赔偿案件管辖权的依据。     

Health Risks of Energy Systems

Health risks from fossil, renewable and nuclear reference energy systems are estimated following a detailed impact pathway approach. Using a set of appropriate air quality models and exposure-effect functions derived from the recent epidemiological literature, a methodological framework for risk assessment has been established and consistently applied across the different energy systems, including the analysis of consequences from a major nuclear accident. A wide range of health impacts resulting from increased air pollution and ionizing radiation is quantified, and the transferability of results derived from specific power plants to a more general context is discussed.
