几何画板模拟阿贝折射仪测折射率

Simulate the Abbe Refractometer Measuring Refractive Index by Geometric Sketchpad

几何画板模拟阿贝折射仪测量液体折射率的过程,相对传统教学手段,更加科学直观并动态演示。通过修改棱镜折射率和待测液体折射率的参数,通过直观几何光学分析,得到为何阿贝折射仪必须满足棱镜折射率大于待测折射率。利用程序易修改特点研究,棱镜不同顶角和考虑色散现象的模拟结果,定量研究差别。

Relative to the traditional teaching means,the geometry sketchpad to simulate the process of Abbe re-fractometer measuring liquid refractive index,which is more scientific and intuitionistic,and it can be dynamic dem-onstration. By modifying the prism refractive index and parameters of the liquid refractive index under test,through the geometric optical analysis,it obtained why Abbe refractometer must satisfy prism refractive index greater than under test. It studied simulation results of prism in different apex angle and consider the dispersion phenomenon u-sing the characteristic which the program is easy to modify,and quantitative studied on the difference.
