我院于１９９０年引进目标光电４４１４Ｋ型脑电图机进行科研和临床使用，其性能稳定，无重大故障，但时常发生一些小问题，虽都能自己排除，却延长了病人检查时间，使工作效率降低。现将常见的故障和对策介绍如下：故障一：脑电笔因墨水挥发干结后被堵塞，造成图形描记不清或 In 1990, our institute introduced the target photoelectric 4414K electroencephalography machine for scientific research and clinical use. Its performance is stable and there are no major faults. However, some minor problems often occur. Although it can be excluded, it prolongs the examination time of patients and makes them work. Reduced efficiency. The common faults and countermeasures are described as follows: Fault 1: The electroencephalograph is blocked after the dryness of the ink is evaporated, resulting in unclear graphic traces or
