摘要：随着教育的迅速发展与普及，高中物理课程也在不断的改革与进步中，跟随新课程标准的脚步，我选取了四套高中物理教材，利用刻画课程难度的定量分析模型对其中的光学部分的内容进行了内容难度分析。这主要从决定课程难度的三要素：课程广度、课程时间、课程深度入手，对各个指标进行量化分析，最终体现出了各版本教材在光学部分的难易程度，并对各个版本教材的设计与编写提出了一些建议和看法。

Abstract：With the rapid development of education with popularization, high school curriculum is also in constant reform and progress, follow the new curriculum standard steps, I chose four sets of high school physics teaching material, using quantitative analysis of characterization curricular difficulty of one of the optical model of the content, the main difficulty analysis from three basic elements of decision curricular difficulty curriculum of breadth, depth of curriculum time, of course, the quantitative analysis of each index, and eventually embodies all versions of the teaching material in the optical parts, and the degree of difficulty of compiling the teaching material of different versions, some Suggestions were put forward.
Key words:Curricular difficulty,Senior high school physics,Course breadth,Curriculum time,Course depth,Of refraction of light,Light volatility.
