每当夏季天气炎热,舰艇受太阳辐射热的影响,舱室温度也相应的增高,特别是机舱、锅炉舱,受机器及锅炉的大量热源,其温度更高,机电人员在这一高温环境中工作,常有大量的汗液排出,使部分营养素和水分丢失,并有食欲减低,身体消耗增大,甚至可出现中暑。为此,我们对一艘老型驱逐舰的机电人员进行了膳食营养调查和汗、尿中无机盐和氮的排出量测定,了解他们的营养与水盐代谢状况,以便为提出改善措施作依据。 Whenever the summer is hot and the ships are affected by solar radiation heat, the temperature of the cabin is also correspondingly higher, especially in the nacelles, boiler compartments, and by a large number of heat sources of machines and boilers, which are warmer and electromechanical personnel work in this high temperature environment , Often a lot of sweat discharged, so that some nutrients and water loss, and reduce appetite, increased body consumption, and even heat stroke may occur. To this end, we carried out a dietary and nutrition survey of an electromechanical officer of an old destroyer and determination of the amount of inorganic salts and nitrogen excreted in sweat and urine to understand their nutrition, water and salt metabolism so as to provide basis for improvement measures.
