  4. An apparent activation energy of 182. 35kj / mol was obtained for the range of 1250 c to 1350 c, and that of 82. 32kj / mol for the range of 1350 c to 1400 c. at the same time, the relation between reaction velocity and reaction time is linear in the range of 1250 c to 1350 c, but it is a parabola curve in the range of 1350 c to 1400 c. so it can be concluded that the process undergone in the range of 1250 c to 1350 c is controlled by chemical reaction while that in the range of 1350 c to 1400 c by diffusion

    本實驗採用的試樣是以鈦白粉和活性碳按1 ： 30的比例混合料為原料，在6mp下成型為37 . 2 26mm的柱形樣塊，分別在1250 、 1350和1400于氮化爐中測定反應速率與時間的關系。當反應在1250 1350時，表觀活化能為182 . 35kj mol 160kj mol ，反應速率與時間的關系是線性的，說明此階段反應由化學反應控制。當反應在1350 1400時，表觀活化能為82 . 32kj mol 160kj mol ，反應速率與時間的關系符合拋物線方程，說明此階段反應由擴散控制。
