针对传统落球法测液体黏度实验的局限性，基于MATLAB GUI设计了虚拟仿真实验. 该虚拟仿真实验直观给出小球在液体中的运动规律，提供了液体温度对黏度的影响、无限广延条件的实现、不同直径小球匀速下落的起点以及生活常见液体的黏度等实验探究模块. 另外，该虚拟仿真实验还结合实体实验设计了实验预习、实验探究和实验考核等学习模块. 在不同的实验模块均设置了可调节的参数，允许操作者根据需要进行相关规律的探究，并且该虚拟仿真实验能够自动分析实验结果、可视化生成实验变量关系图.

In view of the limitations of traditional falling ball method for measuring liquid viscosity coefficient, a simulation experiment is designed based on Matlab GUI. The simulation experiment intuitively gives the motion of the ball in liquid, and provides four experimental modules, such as the influence of liquid temperature on viscosity coefficient, the realization of infinite extension condition, the uniform falling starting point of the ball with different diameter and the viscosity of different liquid used in daily life. Combined with the real experiment, three learning parts are also designed in simulation experiment, from experimental preview, experimental operation to experimental examination. At the same time, the simulation experiment also allows the operator to change relevant parameters to explore the physical laws about liquid viscosity coefficient, and to automatically analyze the experimental results and visually generate the relationship of experimental variables.
