tristable

One is the critical slowing down at the edges of tristable region and the bifurcation, and their critical exponent is calculated;

一种是发生在两类临界点附近慢化现象（即所谓临界慢化），计算出了临界慢化指数。

The tristable resonant tunneling devices(RTD)with a double negative differential resistance in its I-V characteristics have a high current ratio(5.2∶1)of peak to valley at room-temperature.

在I-V特性线上具有双微分负阻态共振隧穿器件,室温下可以达到较高电流峰谷比5.2∶1。
