The structure evolution and reaction mechanism of silicon - iron composite powders treated at the temperature ranging from 700 c to 1200 c respectively were carefully investigated through xrd , sem , epma , dsc . it was found that the chemical formula , fe + si - fe ( si ) + fe3si ( si ) , controls the reaction process , and the reaction mechanism of powder homogenization was clarified 通過利用xrd , sem , epma , dsc等多種測試手段,詳細研究了鐵硅復合粉末帶材在700 1200的熱處理溫度條件下的反應狀況及結構變化,明確了反應過程中的化學方程式: fe + si fe ( si ) + fe _ 3si ( si ) ,并解釋了各個熱處理溫度范圍內,鐵硅粉末均一化的反應機理。

Jack : the machine won ' t boot , it contains information that might stop a terrorist incident , the chemical formula of a cure for cancer and people ' s lives depend on me 這機器不能啟動了,它里面的信息有可能阻止一場恐怖襲擊,包含的化學公式可以治愈癌癥,無數人的生命都懸在我手上。

Green gas has always been mislabelled , with fake chemical formulas and incorrect pressure specifications - nobody questioned them 同時,綠氣罐子外面也化學成份和壓力參數也是被(廠家)故意錯標的,長期沒有人去懷疑它。
