著名物理教育家朱正元教授在美国获得博士学位回国后,他几十年如一日,始终从事物理学的基础理论教学和物理实验工作.在这些工作中,他依据当时国家贫穷落后,农村、山区中学缺乏教具、仪器的特点,提出了“坛坛罐罐当仪器,拼拼凑凑做实验”的主张,并为此终生以示范作用影响并带动 After the famous physicist Professor Zhu Zhengyuan returned to China with a doctoral degree in the United States, he has been engaged in physics fundamental theory teaching and physics experiment work for decades. In these tasks, he was based on the poverty and backwardness of the country at that time, and rural and mountainous secondary schools. Lack of teaching aids and instrumental characteristics, he put forward the idea that “animals and cans should be used as instruments and put together and experiment together”.
