摘    要:
根据流体力学Young-Laplace公式和微分几何学主曲率方程,利用液体自由面的对称性质建立数学模型,并导出静态水银液滴自由面函数方程,然后对只有重力作用下的水银液滴建模,利用MATLAB求解出自由面函数方程,并仿真、绘制出了水银液滴在只有重力加速度下的自由面函数曲线,最后分析了影响仿真的因素.对静态水银液滴在重力加速度下的建模仿真,将对水银电容式加速度传感器的研究有重大意义.

关 键 词:水银液滴  建模  仿真  自由面函数方程  水银  液滴  建模仿真  仿真研究  droplets  mercury  static  simulation  意义  加速度传感器  电容式  因素  影响  分析  函数曲线  重力加速度  绘制  求解  MATLAB  重力作用

Abstract:
The mathematical model and the function equation of free surface of mercury droplets are established in accordance with Young-Laplace function, principal curvature equation in differential geometry and the symmetry of free surface of liquid droplet configuration. Then a model for mercury droplets with only action of gravitation is setup. The function equation of free surface is solved with MATLAB. With the simulation results, the curves for free surface functions are plotted in case of only acceleration of gravity. Finally the factors affecting the simulation is analyzed. Modeling and simulating for mercury droplets under the action of gravitational acceleration will he helpful to study of accelerometer using mercury.
Keywords:mercury droplet   modeling    simulation    function equation of free surface
