摘要: 从理论分析、数值模拟和实验验证三个方面,研究了各向同性薄膜受外力压迫时产生的形变,发现该形变对运动在薄膜表面的物体的影响可以等效为一个二维空间的引力场.进一步,本文研究了质点在该二维空间引力场下的运动,阐述了该引力场与三维空间引力场的异同.

Abstract: The deformation of an isotropic elastic membrane that is produced by external force loaded upon the cenlrum is studied through theoretical analysis, numerical simulation and experiments. The results show that the in- fluence of the deformed membrane to an object moving on it can be equivalent to a" two-dimensional gravitational field". In addition, the motion of a mass point put into this" gravitational field"is investigated, and the difference from three-dimensional gravitational field is discussed.

Key words: isotropic elastic membrane, deformation, two-dimensional gravitational field
