【摘要】 本文在物理化学实验教学中,以对曲线作切线法为例,介绍了一种新的教学方法—计算机辅助作图(CAD)。由于该法克服了传统手工作图法的费时、费力,或因人为随意性造成较大误差等缺点,以其作图精准,误差小等优点,成为实验教学中新的应用。更多还原

【Abstract】 This paper took tangents of curve as example to introduce a new kind of instructional method——CAD (computer aided design) method, which is more efficient than traditional hand drawing. It is expected that CAD method will be a new application in experimental instruction.更多还原
