premonitory

It is one of mechanisms of plastic distortion , at the same time it is also the beginning of microcosmic damage and rupture before the macroscopical destroying of materials , it representatives a mid - state between materials “ macroscopical rupture and bend , it is considered a premonitor that the rupture of polymer material 它是材料塑性變形的機制之一,同時又是材料宏觀破壞以前微觀上損傷、破壞的開始,它代表材料微觀斷裂和屈服之間的一個中間狀態,可以看作是聚合物材料宏觀斷裂的先兆。

In this paper , the al3 + - doped zno thin films were prepared on na - ca - si glass substrate ( microscope slides ) by sol - gel process from 2 - methoxyethanol solution prepared by zinc acetate as premonitor , monoethanolamine as stabilizator and aluminum chloride reaction . homogenous , transparent , polycrystalline zno thin film was formed finally by diping coating conducted for film - plate on substrate , drying , pre - heat - treatment , anealing 所用的溶膠是以乙二醇甲醚為溶劑,醋酸鋅為前驅體,乙醇胺為穩定劑反應制得,用浸漬提拉法在基體上鍍膜,經烘烤、預燒、退火,最后形成均勻、透明的多晶zno薄膜。
