【摘要】 采取了四个有效措施以促进边界元法的实用化，它们是，提供了一个适应性很强的三维前处理系统；将可视化技术嵌入到分析和优化的软件系统中；采用半解析函数大幅度地降低了数值分析问题中的未知数；提供了一个解高阶非对称满阵方程组的新解法。更多还原

【Abstract】 By comparison the volumn and power density of REPM synchronous machine and exciting magnetic one,the thesis researches the volume and power toplimit.It points out there is a volume and power toplimit,under the toplimit,REPM synchronous machine has higher power density.The toplimit is affected with REPM material features and machine number of pole-pairs.更多还原
