报导了有关指挥控制工效等项研究的主要结果：（１）监视工效的昼夜变化与作业特点有关，简单的辨识作业工效以后半夜（０１：００－０４：００）最低，该时Ｐ３００幅值减低，潜时延长。（２）认知工效随难度增加而显著下降；Ｐ３００潜时延长，幅值增高；但过负荷时，Ｐ３００幅度降低。（３）感觉型作业的觉察力随作业时间延长而显著降低；Ｐ３００幅值增高，反映信息加工努力程度提高，有利于防止工效下降。双重作业总水平显著低于单项作业，个体差异加大。内向组持续监视工效在某些方面优于外向组。（４）语音技术对提高人－机系统工效是可行的，尤其在多重作业条件下的作用更为明显。文中对上述结果在工效评定、作息制度安排、操作者选拔以及人－机相互作用方面的意义进行了讨论。
The main results of the study on command and control work efficiency are reported. (1) The day and night changes of monitoring ergonomics are related to the operation characteristics. After midnight (01: 00-04: 00), which is simple to identify work efficiency, the amplitude of P300 is reduced , Potentially prolonged. (2) Cognitive work efficiency decreased significantly with the increase of difficulty; P300 prolonged and the amplitude increased; but when overload, P300 amplitude decreased. (3) The perceived power of sensory operation decreased significantly with the prolongation of operation time; the amplitude of P300 increased, which reflected the improvement of information processing efforts and the decrease of ergonomics. The overall level of dual operation was significantly lower than that of single operation, and the individual differences increased. Intrusive team continued to monitor ergonomics in some ways better than the outgoing group. (4) Speech technology is feasible to improve man-machine system efficiency, especially under the condition of multiple jobs. The paper discussed the significance of the above results in terms of work efficiency evaluation, work schedule arrangement, operator selection and man-machine interaction.
