摘要
试行化学实验小量 -半微量化 ,试剂用量可减至常量的 1/10～ 1/2 ,配套仪器规格也实行小型化 .实践证明 ,此项改革可节约实验开支 ,减少环境污染 。
Chemistry experiments were studied through miniaturization. The result shows that the amount of the primary reagents can be reduced to about 1/10～1/2 of the normal amount, and that the specifications of the instruments should correspond to the amount of reagents. This change can save the experimental expenditure, reduce the environmental pollution, and serve as the standardized operation for students.
