摘要：微机保护双重化配置是指保护装置和二次回路接线均双重配置分别组柜，每个保护柜均按单重配置并有独立完整的接线，当双重化配置时只增加1面保护柜。利用断路器本身的防跳和采用2个跳闸线圈的二次接线，是与实现保护双重化配置相适应的配套接线。在同一个保护柜内主、后微机一体保护或主、后微机分体保护，用1组电压互感器和1组电流互感器。在连城发电公司设计中，保护装置双重化配置选型应一致。

摘要：To study the effects of perceived control on human thermal sensation and thermal comfort in heated environments,a psychological experiment was *** total,24 subjects participated in an *** experiment consisted of two cases in which the indoor temperature was set at 18℃ with different cold radiation *** experiment lasted for 120 min and was divided into three phases,adaptation,without perceived control and perceived *** the second phase,the subjects were told in advance that the indoor temperature could not be *** the third phase,subjects were told that they could adjust the indoor temperature to meet their own thermal expectations,but the indoor temperature could not actually be *** results showed that the effect of perceived control on thermal sensation was related to the thermal *** people with strong expectations for a neutral environment,perceived control improved their thermal sensation by satisfying their thermal *** people with low thermal expectations,perceived control reduced their thermal tolerance to the environment,eventually leading to thermal *** new findings provide more supports for the importance of psychological effects and a reference for the personal control of heating temperatures.

摘要：植被冠层间隙率的研究至今已有３０多年的历史。间隙率模型的研究一直沿着辐射传输方向及几何光学方向发展，本文试图将两者结合起来得到一个更为一般的间隙率模型。要验证模型，实验数据的获取是极其重要的，为了获得准确的数据，我们对观测进行了精心的设计，并在测量方法上有所创新，如“摄影法”，“平行光孔孔法”等都是经济而方便的方法。

摘要：基于全国热舒适调研数据库,对夏热冬冷地区自然通风环境中人体热舒适进行了研究,分析了代表性城市上海和武汉的热环境参数和人体主观热反应,建立了2个城市的热感觉评价模型和热适应模型,得到了热中性温度和人体可接受温度区间。结果表明,上海市和武汉市在自然通风环境下的人体可接受温度上限较高,80%的人可接受温度上限均为30.7℃。建立了夏热冬冷地区过渡季自然通风环境热适应模型。通过多元线性回归分析,发现室内空气温度和服装热阻对上海市人员热感觉具有显著性影响,室内空气温度、相对湿度和人员服装热阻对武汉市人员热感觉具有显著性影响,其中室内空气温度为影响最显著因素。
