gas activation 中文意思是什麼
-
The result shows that argon gas can not only promote the excitation of plasma at low pressure, but also improve discharge state, increase the density and activation of reaction radical and improve the quality of diamond films. on the other side, argon can cool the plasma and maintain low temperature of substrate due to its big ionization section and high collision probability with gas molecules
結果表明，氣體系統中引入氬氣一方面不僅有利於維持低壓放電，而且改善放電狀態，提高反應活性基濃度和活性，提高低溫沉積金剛石膜的質量；另一方面，由於其大的電離截面使其和電子碰撞的幾率大大提高，對等離子體進行冷卻，有利於基片溫度的降低。 -
The nanometer powder had lower sintering temperature than oxide powder because of its high surface activation and the difficulty of sintering fine material because of gas transport process predominating the sinter process
納米粉體具有高表面活性，能在更低溫度下實現燒結，但同樣是因為高表面活性，使鋰揮發現象加劇，氣相傳質在燒結過程中佔主導地位，難以燒結出緻密材料。
