The system operates in a fail-safe mode since the microprocessor is controlling the EXPOSE signal and in addition pulsing a second signal at a 400Hz rate.
此时系统工作在安全模式，因为微处理器控制着曝光信号的产生并且还发出一个400Hz的脉冲信号。
The mode competition and self-pulsing effect were regarded as the main factors that affect the output stability performance of the laser.
模式竞争和自脉动效应是影响激光器输出稳定性能的主要因素。
