我于1955年中学毕业后考入大学以来,已受到近二年的高等教育,学习上出现的一些困难,自然原因很多,但有些困难也是与中学学习中的缺点分不开的,下面简单谈一下化学实验方面的问题。大学化学实验第一次是领取仪器,仪器单上印着各种仪器名称,很多同学都认不得。如看见了分液漏斗和乳钵却叫不出它们的名字,分不清烧瓶,圆底烧瓶,蒸馏烧瓶。至于各种仪器的规格就更不知道了。第二次实验为基本操作,很少有人作出合乎要求的滴管,弯的玻璃管也粗细不均。试管拿法,加热,移液方法以及实验姿式都各式各样,还得由教师一个个地纠正。装置较复杂的实验,所用时间比实际操作的时间还长,往往由于装置技术不佳而发生漏气等现象,得不出很好的实验结果。上述的情况不只是两三个人,而是大多数同学存 Since I graduated from high school in 1955 and admitted to university, I have experienced some difficulties in higher education and learning for nearly two years. There are many natural reasons for this. However, some difficulties are inseparable from the shortcomings of secondary school. What are the chemical experiments? University chemistry experiment is the first time to receive instruments, instruments printed on a single name of various instruments, many students recognize it. If you see the separatory funnel and mortar but could not name them, can not distinguish between the flask, round bottom flask, distillation flask. As for the specifications of a variety of instruments even more do not know. The second experiment for the basic operation, few people make the desired dropper, bend the glass tube uneven thickness. Test tube to take method, heating, pipetting methods and experimental attitudes are varied, have to be corrected by the teachers one by one. Device more complex experiments, the use of time than the actual operation of a long time, often due to poor device technology and so the phenomenon of leakage, can not get good experimental results. The above situation is not just two or three individuals, but most of my classmates save
