摘要: 微分方程在现代科技、工程领域中的作用日益显著,本课题组多年来在微分方程可积性和解析求解方面做了很多机械化工作,研发出了一系列Maple应用软件.基于这些应用软件、计算机代数系统Maple及一些开源技术,课题组研发了一个在线的开放的方程自动求解平台Emathema,为用户提供便捷的代数计算和绘图服务.在此平台上,用户不仅可调用已嵌入的Maple外部应用软件求解非线性代数和微分方程(组),而且在交互方式下可进行几乎所有和方程相关的简单符号计算,所有的计算结果均以可视化的方式输出.

Abstract: Differential equations are playing more and more important role in modern science and technologies, engineering. On solving and integrability analysis of differential equations, our research group developed a dozen different off-line related software based on Maple. On the basis of these Maple packages, Maple and some open-source technologies, an online automated computing platform for equations called Emathema was proposed and implemented. Emathema can provide convenient and efficient online computing and graphing services for users. On this platform, users can not only solve nonlinear algebraic and differential equations using external Maple packages, but also execute almost all simple symbolic computations related to equations in the interactive mode. For each input, Emathema outputs the computing result visually.

Key words: symbolic computation, online computing platform, Maple package, differential equation
