This method estimates filter gain matrix K directly, avoids calculating system noise covariance matrix Q and measure noise covariance matrix r, it improves stability of the system.
这种方法采用直接估计增益K，避免了求解系统噪声方差阵q和量测噪声方差阵r，使系统的稳定性增强。

When Q-switch and gain switch were applied the peak pulse power was increased and pulse width decreased.
利用增益开关和Q开关双机制作用，压窄了调Q脉宽，提高了输出功率。

The microresonator includes an active gain medium and a Q-switch that extend lengthwise between the opposed end faces of the microresonator.
