In newborns, a subnormal temperature-rather than a fever-may be a sign of serious illness. 对于新生的婴儿来说,不是发烧,而是低于正常温度,也许是严重疾病的一个迹象。
A method for automatic extending the tire curing period at a subnormal temperature was proposed. 介绍一种轮胎硫化欠温自动延时的办法。
The results show the lower subnormal pressure and the higher ambient temperature, the shorter existing time for fuel droplet. 结果显示,负压环境下,压力越低,环境温度越高,燃料液滴的生存时间越短。
