正常人体每天出入量正常***24小时液体出入量为2000,2500ml摄入量(m1)排出量(m1)饮水1000,1500尿1000,1500食物水700粪150无形失水850内生水300呼吸蒸发350皮肤蒸发500入量2000,2500总出量2000,2500一、水的平衡(一)体液的含量及分布人体体液及其组成成分比较恒定,只在较小范围内波动。人体内体液总量与性别、年龄及胖瘦有关,正常成年男性液体总量占体重的60%,女性为55%,婴幼儿为70%,80%,随着年龄的增长和脂肪量增多,体液量将减少。体液中细胞内液男性占体重的40,,女性,;细胞外液中组织间液为15,,血浆为5,。正常情况下,体液占35,,细胞外液占20比例相对恒定,各部分之间又不断地进行交换,保持动态平衡,维持内环境的稳定,保证人体正常的生理功能。例题:关于正常体液含量的叙述,错误的是A***男性的体液总量占体重的60%B男性多于女性C***多于老年人D婴儿多于***E肥胖者多于肌肉发达者正确答案:E(二)24小时液体出入量的平衡正常***24小时液体出入量为2000,2500ml摄入量(m1)排出量(m1)饮水1000,1500尿1000,,hardnesstestsshouldbeconducted,hardnesstestsamplingofnotlessthan10%,hardness120%,15CrMohardnessofcarbonsteelpipeshallbelessthanbasemetalsteelafterheattreatment,hardnessshouldnotbegreaterthantheparentmaterialof125%.ordingtothedesignrequirements,nonodesignrequirementstheSH3501-2002table10"eptablelevel",andfixednumbernotlessthanthetotalnumberof40%#steelhighpressuretube,x-rate,thesituationmaynotallownon-destructivetestingbyγ-ray,usedweldbackingandtwo-layerweldsbeforefilledbyxraydetectionmethod,...:ordancewiththeMinistryofpersonnelissuedbytheboilersandpressurevesselswelderexaminationrulesforqualificationexamination,,,tookpartinallkindsoflarge,mediumandsmallstoragetank,pressurevesselwelding,withrichexperience,manualweldingcharacteristicsarenotsubjecttolocationrestrictions,,2500总出量2000,2500当出现异常时,如入量不足或丢失过多超出调节范围将出现脱水;相反,入量过多或排出过少将发生水潴留,甚至水中毒。了解这些变化,有助于预防体液
