A simple example of the first type is the slide rule, which mathematicians and scientists have been using for generations . 好几代数学家和科学家沿用的计算尺就是第一类中的简单例子。
The seemingly limitless wealth of consequence that flow from the axioms continue to challenge the minds of generations of mathematicians . 来自原理的表面上无限丰富的推论,继续鞭策几代数学家的意向。
Many algebraists are engaged in studying this theory 许多代数学家均从事morita对偶理论的研究。
