并以煤气罩式退火炉为例，建立了该过程的数学模型，提出了有煤气压力干扰补偿方案。
The mathematic model of this process is built based on a covered anneal gas boiler, and a disturbance compensation method is provided.
因此，准确测量天线罩电厚度是实现电厚度误差高精度补偿修正的关键。
So it is crucial that measuring electrical thickness exactly in order to realize precision compensating electrical thickness error.
同时又采用了波纹管补偿器作为活动烟罩循环管道的柔性连接件，大大提高了设备的可靠性和安全性。
Bellows compensators were used as flexible couples of circulation pipes of the moving sm oke cover, which greatly in-creased reliability...
