目的 :探索现役 92海军舰艇艇员防寒服保暖量不足的原因。方法 :以人体作受试者 ,在低温实验室模拟一定的条件下 ,测量人体温度变化。结果 :(1)罩衣挡风性能差 ,降低了保暖效果 ;(2 )适体性很差 ,棉衣与绒衣不配套 ,袖管和裤脚管的挡风套箍在绒衣上 ,极不适 ,同时限制了四肢肢端的血液循环 ,更不利御寒 ;(3)防寒靴和手套的保暖量严重不足 ,与衣服主体不配套。结论 :为今后的改进提供了依据。 Objective: To explore the reason why there is not enough warmth in the winter clothes of 92 navy naval crews. Methods: The human body as a subject, in a low temperature laboratory simulation of certain conditions, the measurement of human body temperature changes. Results: (1) The performance of windshield was poor, which reduced the effect of keeping warm. (2) The poor fit, the unlined cotton coat and cashmere sweater, Limits the extremities acral blood circulation, but also unfavorable to keep warm; (3) cold boots and gloves a serious lack of warmth, and the main body does not match. Conclusion: This provides the basis for future improvements.
