Those bubbles arise because the thin sticker film expands at a different rate than the window glass when they both heatup.
那些气泡出现的原因在于:热胀冷缩时,车贴薄膜的延展性和车窗玻璃大不相同。

By optimizing composition, foundry method, melting process and heat treatment process, the rate of qualified castings was increased up to 85%.
通过对成分、铸造工艺、熔炼工艺及热处理工艺的优化,使铸件的工艺出品率达到85%。

If there is any doubt regarding the turndown capability of the furnace to achieve this heatuprate, the furnace should be started after the addition of gasoil.
