随着“3 +Ｘ”高考模式的进一步深化 ,各学科知识互相交叉、渗透、融合已成必然 .数学与物理、数学与化学有着密切的联系 ,联系物理、化学知识的数学问题背景新、立意高 ,能较好地提高学生的创新精神与创新能力 .但解决这类问题常常因不明确其理、化背景后的原理 ,找不到物理、 With the deepening of the “3 +X” college entrance examination model, it has become inevitable that the knowledge of each discipline has been intersected, infiltrated, and merged. Mathematics is closely linked with physics, mathematics, and chemistry. Mathematical problems with knowledge of physics and chemistry are new. High, can better improve the students’ innovative spirit and innovative ability. However, solving such problems is often due to the principle that they are not clear and their backgrounds cannot be found.
