高真空静电减重力装置中聚合物薄膜减重程度的理论分析

Theoretical Analysis of Reduced Gravity of Polymer Films under High Vacuum Electrostatic Field

本文根据力学原理首次建立了静电减重力方程，再根据电磁场理论导出了平板电极下聚合物薄膜表面的自由电荷面密度，从理论上计算了静电减重力装置中聚合物薄膜的减重程度。

In this paper the electrostatic reduced gravity equation was established on the basis of mechanical theory. The free charge density on polymer film surface under the action of parallel board bi polars was calculated according to electromagnetic theory, and consequently the reduced gravity of the polymer film was calculated. We believe that this work can provide theorectical basis for space experiments.
