真空纳米微电子结构自发射阴极的电磁场研究

介绍了一种改进的“透镜”算法。用该算法和相应的实验研究了两种自发射阳极的静电场特性（尖锥直径为１０~１ｎｍ）,其电场放大系数达到１０~２。并研究了在阴极尖锥附近的电场强度与尖锥结构的关系：分析了表面粗糙程度的影响。最后所得的计算机算法和程序适用于研究任意形状的纳米尖锥阴极。     

The origins and consequences of public trust in government: a time series analysis

The study of citizens' trust in the national government has been primarily individual-level, cross-sectional analysis. In the current research, we develop a quarterly time series measure of trust in the U.S. national government from 1980 to 1997 and conduct the first multivariate time series examination of public trust in government. We find that negative perceptions of the economy, scandals associated with Congress, and increasing public concern about crime each lead to declining public trust in government. Declining trust in government in turn leads to less positive evaluations of Congress and reduced support for government action to address a range of domestic policy concerns. These results provide new evidence of the influence of public concern about crime and the centrality of Congress in understanding public evaluations of the national government and new evidence of how declining levels of trust in government may influence elections and domestic policy making.
