要做化学实验,就必须使用化学仪器和消耗一定数量的化学药品。随着我国教育事业的发展,特别是文化大革命以来,全国城乡新添了不少中学和公社试验站,化学仪器和化学药品的生产,虽然大幅度地增长,但是还远远不能满足当前教育事业飞跃发展的需要。面临这个矛盾怎么解决呢?毛主席教导我们说:“我们要进行大规模的建设,但是我国还是一个很穷的国家,这是一个矛盾。全面地持久地厉行节约,就是解决这个矛盾的一个方法。”因此必须发扬自力更生,艰苦奋斗的革命精神,厉行节约,少花钱多办事,不花钱也办事,充分发动群众,积极动脑、动手,利旧利废,以土代洋,土洋结合,因陋就简地也可以完成中学化学教学中的部分实验任务。下面列举一些做法,供同志们参考:
To do chemical experiments, you must use chemical equipment and consume a certain amount of chemicals. With the development of education in our country, especially since the Cultural Revolution, many secondary and commune pilot stations have been added to the urban and rural areas across the country. Although the production of chemical instruments and chemical drugs has increased substantially, it still falls far short of the current educational undertaking Leap development needs. In the face of this contradiction, how can we solve it? Chairman Mao taught us: "We want to carry out large-scale construction, but our country is still a poor country. This is a contradiction. Comprehensively and lastingly practicing economy is one way to solve this contradiction. . Therefore, we must carry forward the revolutionary spirit of self-reliance and hard work, practice economy, do more with less and pay more, do our work without paying money, fully mobilize the masses and actively use our brains and hands, Because of its simplicity, it is also possible to complete some of the experimental tasks in secondary chemistry teaching. Here are some practices for comrades reference:
