非线性弦振动方程的新精确解

利用改进的tanh函数法，将非线性弦振动方程化为一阶非线性常微分方程组。通过求解这个非线性常微分方程组，获得了非线性弦振动方程的新精确类孤子解、三角函数解、复数解。这种方法也适用于求解其他非线性发展方程。     

论余华《活着》的死亡体验

《活着》展示了一幅幅死亡全景图。余华根据他儿时的生活经历以及对现实的理解，讲述了一个个死亡的事件。《活着》死亡的背后，超越了作者以暴力、血腥、恐惧渲染死亡的怪圈，寄托了作者对中国几千年来农民苦难命运的关注与思考。中华民族的传统的精神原型给予人们面对死亡的勇气与信心。

Children’s solving of ‘Tower of Hanoi’ tasks: dynamic testing with the help of a robot

Abstract

The present study investigated the usefulness of a pre-programmed, teleoperated, socially assistive peer robot in dynamic testing of complex problem solving utilising the Tower of Hanoi. The robot, in a ‘Wizard of Oz’ setting, provided instructions and prompts during dynamic testing to children when they had to solve 3?D Tower of Hanoi puzzles. Participants were 37?second grade 8-year-old children, of whom half received graduated prompts training between pre-test and post-test, delivered by the robot, and half did not. It was found that children’s progression in task accuracy varied considerably, depending on whether or not children were trained in solving Tower puzzles. Trained children showed greater progression in the number of Tower problems that they could solve accurately, made considerably fewer steps, although the Tower puzzles increased quickly in difficulty level. The mean completion time of trained children decreased at a slower rate than that of the untrained children, but both groups of children took considerably more time to think and plan ahead before they started the solving process. Only moderate relations with planning behaviour were found. In general, the study revealed that computerised dynamic testing with a robot as assistant has much potential in unveiling children’s potential for learning and their ways of tackling complex problems. The advantages and challenges of using a robot in educational assessment were discussed.
