The slowing down in optical bistability;

光學雙穩系統中的慢化現象

Studying two kinds of the slowing down in the bistability chemical reaction system,the one is the critical slowing down at the edges of bistable region and its bifurcation;the other is the slowing down,which is far from the critical point.

對具有雙穩性的化學反應中的慢化現象進行了研究 ,指出了兩類臨界點附近的慢化現象 (即所謂的臨界慢化 ) ,計算出了它們的臨界慢化指數 ,發現這兩類臨界指數與混沌運動中的切分叉點及倍周期分叉點相一致 。
