Vibration Exposure of taxi driver has not only impact on driverg health but the safety of driving. The constantspeed running test and a monitoring test in actually situationare done. The taxi driver vibration exposure testing data is analyzed, and it is found that the vibration exposure evaluation of constant speed test cant satisfy the actually situation. At last, animpersonalassessment is done according to the vibration exposure evaluation standard of ISO2631. 相似文献

校园绿化小气候效应及其对人体舒适度的影响——以山西农业大学校园为例 总被引:1,自引:0,他引:1
为了明确校园绿化环境对校园小气候的影响,对校内3个绿化地和1个非绿化地进行了空气温度和湿度的对比观测,并利用校外自动气象站的温湿度资料和校内各测点温湿度进行了比较。研究表明:绿化可以使校内气温下降,空气湿度增加,从而增加人体的舒适感。校内绿地和非绿地空气温湿度与校外气象站的温湿度观测值极显著相关,并可以建立回归关系显著和决定系数(R2)较高的线性回归方程。校园绿化可以改善校内小气候环境,校内的小气候环境与校外大的气候环境密切相关。 相似文献

Little work has been done in the past on how clothing thermal and moisture transport properties affect human comfort sensations
during different periods of an exercise. In this work, by correlating the thermal and moisture transport properties of T-shirt
fabrics and garments with the comfort sensations during different stages of exercises, we found that thickness, thermal insulation
and warm/cool feeling of the T-shirt fabrics are important to warmth sensation, skin wetness sensation and overall comfort
throughout the entire period of exercise and immediately after the exercise. Water vapor transmission properties of T-shirt
fabrics or garments are not important to comfort sensations at the start of the exercise, but become an important factor to
comfort sensations in the middle of the exercise up to the resting period after the running exercise, probably due to the
fact that sweating occurs during these periods. Fabric water absorption and air permeability are not significant factors at
the start and during the exercise, but are important after exercise, probably because these properties determine how quickly
the skin can be dried after sweating. 相似文献
