丙烯酸酯聚氨酯紫外固化凝胶生成动力学研究

采用丙烯酸酯聚氨酯和二苯甲酮/安息香乙醚复合光敏剂,对该体系紫外光固化反应的凝胶生成动力学进行分析。用红外光谱定量测定光聚合过程的变化,发现光聚合反应主要是以双键打开,交联为特征的,并得出1408cm~(-1)双键吸收峰随光照时间而变化的关系式:P_(c=c)=0.325 t~(0.135)。临界凝胶点可由双键反应程度与凝胶分数之间关系外推得到,凝胶点后,体系中存在一个凝胶与溶胶之间分配关系,此时凝胶与溶胶共存,凝胶中双键反应程度P_(A(g))>总双键反应程度P_A>溶胶中双键反应程度P_(A(S))。随着凝胶增加,P_A和P_(A(g))逐渐上升,而P_(A(s))下降。此体系的紫外固化实验工作曲线与理论值基本一致。     

仲胺衍生物柴油流动改进剂

考察了十八种胺衍生物改善高含蜡柴油低温流动性的作用规律。结果表明，仲胺衍生物主要是通过增溶柴油中的长链正构烷烃，使浊点、冷滤点降低，从而改善柴油低温性能。仲胺衍生物与T1804流动改进剂（乙烯-醋酸乙烯酯聚合物）复合可以改善蜡晶的分散性能，对降低柴油冷滤点有增效作用。

泊松方程数值解法的加速收敛法

用数值方法对泊松方程求解时，往往要对迭代的中间结果作适当的压缩处理，以加快收敛速度和避免溢出。本文提出一种单一指数因子的非线性压缩法。一维数值模拟结果表明，平衡态时不必进行压缩处理。而在非平衡态时，最佳指数压缩因子的大小与杂质浓度有关。参考本文给出的数值计算结果，根据给定器件的杂质浓度分布，选定一最佳指数压缩因子，可以使泊松方程的数值求解过程具有最快的收敛速度。     

Theoretical foundation of the 80/20 rule

A rigorous analysis of the 80/20 rule is made using an index for the observed values of the variables. Three important findings are identified. First, a sufficient condition is provided for Burrell's inverse relationship between minimum holdings and average circulation rate. Second, an indexed version of Lotka's law is used to derive a sufficient condition for Egghe's finding on the 80/20 rule. Third, through the computer simulations of the Simon-Yule model of Lotka's law, we identify the entry rate of new holdings as well as the number of circulations when the entry rate is a decreasing function to be crucial factors for the pattern of the 80/20-type curve.     

Mobility modeling, location tracking, and trajectory prediction inwireless ATM networks

Wireless ATM networks require efficient mobility management to cope with frequent mobile handoff and rerouting of connections. Although much attention has been given in the literature to network architecture design to support wide-area mobility in public ATM networks, little has been done to the important issue of user mobility estimation and prediction to improve the connection reliability and bandwidth efficiency of the underlying system architecture. This paper treats the problem by developing a hierarchical user mobility model that closely represents the movement behavior of a mobile user, and that, when used with appropriate pattern matching and Kalman filtering techniques, yields an accurate location prediction algorithm, HLP, or hierarchical location prediction, which provides necessary information for advance resource reservation and advance optimal route establishment in wireless ATM networks
