We use a bulb for heating and with the help of double-direction controllable silicon that controlled the calefaction value, and then detected by temperature sensor, the input signals are amplified and analog signals are transformed to digital signals. Finally the signals reach single-chip. Then single-chip compare the value of preliminary temperature with ones of pragmatic temperature, and modulate to operate.

主要采用的是光源加热，由双向可控硅控制其加热量的大小，由温度传感器检测现场温度，该信号经过放大及A/D转换后进入单片机，单片机将设定的温度值与实际检测到的值进行比较运算，并输出。

After the United midfielder Paul Scholes was sent off shortly before half-time, the uneasy peace was dramatically broken Soon both crowd and cameramen didn't know which action to watch- the drama on the pitch, or the carabineer as they waded into United's fans without any apparent restraint.

就在曼联的中场大将斯科尔斯在上半场结束前几分钟被罚下之后，这种好不容易控制下来的平静局势再次被破坏，现场观众和摄影记者一时间不知道该往哪看了，一边是渐渐进入高潮的比赛，一边是看台上的冲突，罗马警察正肆无忌惮的冲入曼联球迷的人群。
