Based on the principle of mechano - chemistry , the strong shock and crashing mechanical force produced by ls - 250 pulverizer can act to the surface of superfine carbon and white carbon particles during the process . the result of the experiment indicated that distortion and amorphism change occur to the surface crystal lattice of carbon particles , and the phenomena are prick up as the action time of mechano - chemical force 依據機械化學原理利用ls一250型流能粉碎機高速旋轉的動齒工作過程中產生的強烈沖擊、碰撞機械力,使其作用于超細石墨及白碳黑顆粒表面,檢測表明,石墨粒子表面晶格發生畸變及無定形化,且隨著機械力作用時間的延長而加劇。

We found that tio2 thin films are a amorphism when they are not annealed ; they are anatase when annealed at 300 c ; rutile occured be anneled at 700 ; ti02 thin films are transformed into rutile completely when be anneled at 1100 . oxygen - sensing properties of tio2 thin films were analysised , and we found the variation law of sensitivity with the partial pressure of o2 and temperatures . sensitivity increases with po2 / ( po2 + pn2 ) at a constant temperature . the higher working temperature is , the slower sensitivity increasing with po2 / ( po2 + pn2 ) is 對tio _ 2薄膜氧敏器件特性進行了分析,發現靈敏度隨工作溫度和氧分壓變化的規律, 400以上時,在一定工作溫度下,隨氧分壓的增加,靈敏度逐漸升高;工作溫度越高,隨p _ ( o _ 2 ) ( p _ ( o _ 2 ) + p _ ( n _ 2 ) )的增加,靈敏度增加越緩慢,在400下靈敏度隨氧分壓增加最快;在我們所測試的工作溫度點中, 400時具有最高的靈敏度,相對于他人的工作此溫度是比較低的。

Carbon can promote the forming of carbide of fe3c mostly during the ma , while it seems that chromium makes amorphism easier . in addition , this paper also made a research on the milled powder forming technology , and presented some improvement methods 機械合金化過程中,碳元素可以促進以fe _ 3c為主的碳化物的析出,鉻元素使粉末更趨向于非晶態轉變,并使材料出現超順磁現象。
