我们在1990年和1991年召开的全国第一、二次微型化学实验研讨会精神的启发下,在吸收兄弟院校经验的基础上,在石油化工系92级和93级三个专业先后八个班开展了微型无机化学实验的尝试,受到了学生的普遍欢迎,提高了教学效果,从实践中认识到微型实验的许多优越性。下边就谈一谈我们的做法和体会。 一、推广微型化学实验是实验教学改革的重要手段 微型化学实验是指“以微量的试剂,在微型化的仪器装置中进行的化学实验”。试剂用量一般为常规实验的1/10—1/100,反应器的容量约1—10毫升。精巧的微型实 Inspired by the spirit of the first and second seminars on micro-chemical experiments held in China in 1990 and 1991, based on the experience of our brothers and tertiary institutions, we successively held three professional programs at the 92 and 93 level in the petrochemical industry. Attempts to carry out the experiment of micro-inorganic chemistry have been widely welcomed by students and the teaching effect has been improved. Many advantages of micro-experiments have been recognized in practice. Here to talk about our practices and experiences. First, the promotion of micro-chemical experiments is an important means of experimental teaching reform Micro-chemical experiments refer to “a trace of reagents in the miniaturized instrumentation for chemical experiments.” The amount of reagents is generally 1 / 10-1 / 100 of the conventional experiment, the capacity of the reactor is about 1-10 ml.
