摘　　要：综合实验是培养学生综合能力的重要实践教学手段。综合实验中合理设置探索性实验环节,可帮助学生理解复合知识、激发学生自主学习潜能、助力学生综合素质的培养。以"消解-电感耦合等离子体发射光谱仪(ICP-OES)测定废水中多种重金属元素的含量"这一综合实验为例,探讨实验期间探索性环节的导入及其达到的教学效果。教学实践表明,探索性环节的嵌入,有利于综合实验教学内容的开展,更有利于"学以致用"实践创新型人才的培养。Comprehensive experiment is an important practical teaching means to cultivate undergrad- uates＇ comprehensive ability. The introduction of exploratory steps in the procedure of comprehensive experiment can help students understand the composite knowledge, stimulate students＇ self-learning potential. In the experiment of ＂digestion and determination of heavy metals in the wastewater by in- ductively coupled plasma-optical emission spectrometer＂, we explored the process and consequently the effect of exploration practice. The teaching experience showed that the developing of exploratory ex- perimental units could help students understand complex principles more effectively and promote the cultivation of the creative ability of the students more efficiently.
