摘　　要：服装通风策略是改善人体热湿舒适性的重要技术手段。为不同高温作业服装提供有效的通风降温策略,文章介绍了服装通风效率的测评指标及相应的两种测量方法及其特点,回顾了织物通风模型、局部通风模型、动态通风模型、被动通风服模型及主动通风服模型的发展历程,从织物透气性、服装开口、内嵌通风设备三方面阐述了现有服装通风策略对于人体热散失的影响机制。基于此研究现状提出两点展望,即建立耦合人体热生理反应的动态三维服装通风模型,开发多种换热方式相耦合的主动通风服。Outdoor workers often work in high temperature environments in summer.Due to their wearing heavy clothing,the heat loss of human body will be seriously hindered,which increases the risk of hyperthermia.Clothing ventilation strategy is an important technical mean to regulate the heat loss of human body.To increase the heat loss of human body by optimizing the compatibility of clothing fabric,adding clothing openings,and embedding micro-ventilation equipment is of great significance for the protection of health and safety of human.First of all,the evaluation index of clothing ventilation efficiency(i.e.clothing ventilation index),the measurement methods(the CR method and the LH method),the calculation formula of overall and local ventilation indexes,and the advantages and disadvantages of the measurement methods were introduced.The CR method needs to measure the microenvironment volume under clothing,while the LH method does not,and is suitable for measurement under dynamic condition.However,on strong wind conditions,as for the highly breathable clothing,the tracer gas is diffused through the clothing to the outside environment before it is evenly distributed in the microenvironment under clothing,resulting in a larger measurement result of the LH method.Secondly,the development of the fabric ventilation model,local ventilation model,dynamic ventilation model,passive ventilation model and active ventilation model was reviewed.The fabric ventilation model included two mass transfer modes:diffusion and convection.Such a model is represented by the three-node ventilation model,with the inner point referring to the inner layer of yarn,the outer point referring to the outer layer of yarn,and the empty point of air referring to the flowing air.The mass transfer between the inner point and the outer point is diffused,and the mass transfer between the outer point and the empty point of air is convected.The local ventilation model is a double-layer cylindrical model built with the torso or arm as the prototype.The inner cyl
