When the system is initially at high concentration state, with the increasing of the cross - correlation, although the stationary probability distribution ( spd ) of the tf - a monomer concentration at low concentration state is increased, yet the mfpt is decreased due to the decreasing of the spd of the transient states between the two steady stable states which acts just like a " channel "

    其實這兩個結果並不矛盾，因為我們可以看到mfpt似乎與中間的瞬態的幾率分佈的關系更為密切。中間瞬態就類似一個「通道」 ，當瞬態的幾率分佈高時，通道就寬， mfpt就低;反之，當瞬態的幾率分佈低時，通道就窄， mfpt就高。
