中国现代珠算史料（1965年～1988年）

财政部财政科研所处长唐滔默同志出差到桂林，他有闻那里正在召开有十五省(市区)珠算家参加的桂林珠算座谈会，要求到会了解情况，但那时会议已结束。他要求看会议材料，因我是会务主持人，所以，我把会议过程、两期简报向唐处长作了详细汇报。唐即寄回北京财政科研所。     

ACTA MATHEMATICA SCIENTIA

Information for Authors Scope The aim of ACTA MATHEMATICA SCIENTIA is to present to the specialized readers （from the level of graduate students upwards） important new achievements in the areas of mathematical sciences. The journal considers for publication of original research （expository） papers in all areas related to the frontier branches of mathematics with other science and technology.

The Design for Automation of Pellet-Forming Process in HL-2A Pellet Fueling System

In the ever fusion experiments in SWIP, pellet forming process was carried out through adjusting relative devices by staff member in site, which will make every pellet-forming process slight distinction and will result in pellet difference in shape, size and intensity. In the intervals of HL-2A discharges, staff member have to go site to accomplish the pellet-forming process, this wastes human power and increase the potential danger. So it is necessary to develop a remote control system to perform the pellet-forming process. The control system needs have the features of real-time, reliability and be easy to operate and maintain.     

珠算教学能够加强大学生创造性思维培养

江泽民曾经指出：“创新是一个民族进步的灵魂，是国家兴旺发达的不竭动力。一个没有创新能力的民族难于屹立于世界先进民族之林”。创新能力是在相应的创造性的支配下进行的一种积极的、能动的活动。创造性思维是一切创新话动的核心和灵魂。因此，在大学教育中，努力培养学生的创造性思维是培养学生创新能力十分重要的环节。     

JOURNAL OF COMPUTATIONAL MATHEMATICS

The Journal of Computational Mathematics is an international journal on numerical methods, analysis and applications. It publishs original research papers in English, French or German, but preferably in English. Prom 1998, it has appeared bimonthly（instead of quarterly）.     

基于BDF的无约束优化方法的收敛性分析

1.介 绍 在上个世纪的七十年代末、八十年代初,基于常微分方程的优化方法或者说同伦方法是一类与拟牛顿法和共轭梯度法等我们所熟知的优化方法相竞争的重要方法[1-6,8,13,14,16].由于这类方法只是简单地利用现成的数值求解常微分方程的软件包,如CVODE[7]、LSODE[12],对同伦方程(一般是一个常微分方程的初值问题)进行计算,除了一些特殊的病态问题
