手头1份资料表明:夏日期间,农机手饭后马上驾车容易发生交通事故。笔者曾对2000年夏季在某县发生的100起农用车交通事故进行调查,结果发现有21起缘于午饭后疲劳驾车所致。对此,有关生理学家把这一段时间称之为危险的“15分钟”。这是因为人体在夏季高温条件下形成的生理节律决定的。 A piece of information on hand shows that during the summer, agricultural machinery is prone to traffic accidents immediately after driving. I conducted a survey of 100 agricultural vehicle accidents in a county in the summer of 2000 and found that 21 cases were due to fatigue driving after lunch. In this regard, the physiologists call this period dangerous “15 minutes.” This is due to the circadian rhythms that the body forms under hot summer conditions.
