【摘要】 在结构化学教学中,分子对称元素和所属点群的确定是教学的重要内容,在具体教学过程中,采用了实物模型及系统分类等方法,从易到难,分子对称元素和所属点群更易确定.通过这些方法,降低了教学难度,并提高了教学质量和效果。更多还原

【Abstract】 In Structural chemistry, it is important that to confirm the symmetry elements and point group of molecular. In the process of teaching the knowledge, we constructed molecular models and adopted system classification respectively, and with giving example from easy to difficult. So it is more simplify to ensure the symmetry elements and point group of molecular. By Those Methods, it is effectively that reduces the difficulty of teaching and improves the teaching quality.更多还原
