Since a mutual diffusion between adhesive layer and matrix and a innerstress on interfaces exist,there is a optimal thickness of adhesive layer in composites.

由于合物粘接层和基体合物相互及界面内应力存在，合材料中存在一个最合物粘接层。

Streak cathod method which is a kind of qualitative method for measuring the innerstress of deposits was introduced.A semi-quantitative calculating formula for the innerstress was given.

简单介绍了镀层内应力一种定性测定方法-条形阴极法,并列出了其半定量计算公式。
