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。

The transient is seen to be a decaying exponential, and the commonly used measured of the speed of decay is the time constant: The time constant is the time in seconds for the decaying exponential transient to be reduced to e-1=0.368 of its initial value.
