The gain is now well above the (lowered) oscillation threshold.

此时，增益大大超过(降低了的)振荡阈值。

This paper deals with the threshold condition of double resonance parametric oscillation when the absorption coefficient of the signal light is different from that of the idling light.

在信号光和闲置光吸收系数不同的情况下对双谐振参量振荡阈值条件进行了分析。

It is shown that the fluctuation of amplitude at the threshold of oscillation is much greater than that when the system is far from the threshold.

所得结果表明此类自振动系统在自激阈附近的振幅涨落比远离阈值时的涨落大很多。
