THE FINITE AUTOMATA OF EVENTUALLY PERIODIC UNIMODAL MAPS ON THE INTERVAL

For unimodal maps on the interval we prove that, if the kneading sequences (KS) are eventually periodic, then their formal languages are regular ones. The finite automata for such languages are constructed. Comparing with the languages generated by periodic KS, it is shown that the languages here are not finite complement languages.     

PP/TiO2复合材料的力学性能研究

采用熔融共混法制备了PP/TiO2复合材料,并研究了TiO2的表面处理、含量及粒径对复合材料的拉伸强度和缺口冲击强度两大主要力学性能的影响.实验结果表明,钛酸酯类偶联剂能很好地改善TiO2粒子与PP基体的界面相容性,从而使复合材料的力学性能提高;经表面处理后的纳米TiO2所填充复合材料的力学性能明显优于普通TiO2（微米级）;而且处理后的纳米TiO2在填充量为4%时对PP的增强增韧效果最佳.

Combustion energies and standard molar enthalpies of formation for the complexes of the first-row transitional metal chlorides withL-α-histidine

Seven novel solid complexes of the first-row transitional metal with L-α-histidine were synthesized, and their compositions were determined. The constant-volume combustion energies of the complexes were measured by a precision rotation bomb calorimeter. The standard molar enthalpies of combustion and the standard molar enthalpies of formation were calculated. The results indicated that the plots of the standard enthalpies of formation against the atomic number of the metal show a regularity of zigzag.     

应用于加速器驱动次临界系统的程序开发

开发了应用输运理论方法的两套程序系统：蒙特卡罗－燃耗程序系统和输运－燃耗程序系统。针对蒙特卡罗程序不能计算燃料的同位素成分变化，提出将它和燃耗计算程序耦合以完成燃耗计算。燃耗程序所使用的单群截面由蒙特卡罗程序计算。将用于常规反应堆的计算方法和策略推广到输运－燃耗程序系统，这使得计算步序大大简化，并改进了精度。对加速器驱动次临界系统的基准题进行了校核计算，其结果和其他国家的计算结果符合良好，这表明所提出的计算方法与程序系统是成功的。
