摘　　要：浮法玻璃表面渗锡改变了浮法玻璃的化学成分和结构在空间的对称性，使其在浮法玻璃中出现一个特殊的方向，那就是垂直于渗锡层的S方向，这就使浮法玻璃的介电行为和方向有关，本文从理论和实验上证实了这一观点。并提出了一种诊断表面层的新方法。渗锡层诊断证明：渗锡层的介电常数大于浮法玻璃内部的介电常数。The penetration of tin in the float glass changes the symmetry of its chemical composition and structure in space, hence, it leads to producing a special s-direction perpendicular to the tin surface layer. It results in that the dielectric constant in the float glass is depending on the direction of the applied field relative to the glass. The idea above is verified by calculations and experiments.A new method for diagnosing of surface layer js proposed based on the idea mentioned above.It is shown by the diagnosis of tin surface layer that the dielectric constant in the tin surface layer is larger than that inside the float glass.
