论文部分内容阅读
这里我们将王万游、林为干二位同志的文章介绍给读者。 王万游同志现任其单位物理讲师,他对我刊1982年第二期发表的《椭圆形线圈及无线长双曲线导线在其磁点上的直流磁场——比奥—沙伐尔定律教学法举例》一文中有计算上的差错,并在其启发下撰写了文章寄林为干教授。他这种不囿于专家之名的求实精神值得提倡和学习。尤为可贵的是,本文作者林为干教授是我国老一辈科学家,当收到来函和文章后,即表示热情欢迎,将该文推荐给本刊发表,同时他又在王万游同志文章的启发下,撰写了《无线长双曲线型导线在其两焦点上的直流磁场》一文,进一步完善了以上的教学方法。 他们这种互相学习,尊重科学的求实精神,不正是我们教育和科学工作者高尚品德的具体表现吗?对学术问题的争鸣,它不仅可以活跃学术空气,并将促进我们教学和科研质量的不断提高。愿这种精神能继续发扬光大。
Here we introduce Wang Wan-yu and Lin Weijian’s two comrades to the readers. Comrade Wang Wan-yu is currently a physics lecturer in his unit. He gave an account of “DC magnetic field at the magnetic point of oval coils and hyperbolic conductors of wireless long lines - examples of teaching methods by Biot-Savart law” published in the journal No. 2 of 1982, There is a computational error in the essay, and under the inspiration of it he wrote an article by Lin Lin as a professor. His realistic spirit of truth, not to be missed in the name of an expert, deserves to be advocated and studied. Particularly valuable is that the author of this paper, Professor Lin Weigan, is a scientist of the older generation in our country. When receiving the letter and article, he warmly welcomes this article for publication and at the same time he is inspired by Comrade Wang Wan-you’s article , Wrote a “wireless hyperbolic wire in its two focus on the DC magnetic field,” a text to further improve the above teaching methods. Is not this a concrete demonstration of the noble virtues of our educators and scientists that they learn from each other and respect the scientific and realistic spirit? The debate over academic issues not only can boost the academic atmosphere, but also promote the quality of our teaching and research improve. May this spirit continue to flourish.
