The addition of PS can reduce the dielectric constant of glass-ceramic substrate materials effectively, but reduce the flexural strength at the same time.

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。
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.
The results showed that its dielectric constant changes in the scope of 2.90 to 3.30 under the influence of the factors mentioned above, among which the environmental humidity is a dominant one.
