问题背景可导向构建多种解决问题的思维模型 ,形成较强的解决问题的意识和色彩 .在解决问题时根据已有化学知识经验将问题转换成适当的形式 ,构建和发展思维模型 ,就能在思维模型的演变完善过程中 ,创造出最优化的解题思路 ,下面举例说明。一、感知典型材料　激创直觉思维知识 The problem background can lead to the construction of a variety of problem-solving thinking models, forming a strong problem-solving awareness and color. When solving problems, according to the existing knowledge of chemical knowledge, the problem can be converted into an appropriate form, and the thinking model can be constructed and developed. In the course of evolution of the thinking model, create the optimal solution ideas, the following examples. First, perceive typical materials
