When the nano-particles' weight content was 8%, the drop of breakdown strength reach smallest value and the thermo-decomposed temperature reach the highest value.
在硅铝共掺杂的薄膜中，当硅铝总含量为8%时杂化薄膜的击穿强度下降最少，薄膜的热分解温度达到最高值。

The local fractures in gate pier of dam occur while the thermo stresses exceed the tensile strength of concrete, and sometimes, some fractures can extend from dam top to the spillway surface.
This paper research and discuss thermo-moisture effects of C/E composite strength and it's scatter. On the basis of experimental research, practical data and opinion are presentation.
