1·The control circuit used very efficient PID modulation and anticipatory control so the power amplifier had little distortion and fast dynamic response.

它采用了电压闭环负反馈以及有效的PID调节环节和相应的超前校正环节，能保证很小的失真率和快速的动态响应能力。

2·These lessons, promoted China to arise suddenly the public health event medical service treatment system and illness sickness anticipatory control system's promotion.

这些教训，促进了中国突发公共卫生事件医疗救治体系和疾病预防控制体系的升级。
