Recent experiments on the Si (111)(7×7)-(1×1) phase transition showed that when the temperature is raised above the critical temperature, a 7×7 island decays to zero at a constant area decay rate which increases with the size of the initial area.

近期Si(111)(7×7)-(1×1)相变的实验研究发现，将温度升高到相变温度以上时，7×7岛面积以恒定的衰减速率随时间减小至零，且初始面积越大的岛这个衰减速率就越大。

This study examined the alumina ceramic membrane to deal with high turbidity water flux changes in the law of decay was found in the early running flux decay rapidly, the latter tends to slow decay, a linear decline in the overall. 51qikan.

Key words： high-alumina ceramic membrane separation of water turbidity摘要：本实验研究了氧化铝陶瓷膜处理高浊度水时膜通量衰减变化规律，发现运行初期膜通量衰减很快，后期衰减趋于平缓，总体成线性下降。
