摘　　要：针对冬季隔离器内的小气候变化规律,找出它的变化特点,为实验动物的饲养提出合理的调控方法。试验通过三种不同处理,有鸡隔离器、无鸡隔离器、对照,对其进行温度、湿度和CO2变化情况进行观测并对观测结果进行分析比较。结果表明:(1)隔离器内的温湿度及CO2的变化与鸡的活动量大小关系密切;(2)隔离器内的气象要素变化规律与气温的变化规律不一致,一天中最高温度出现的时间早于气温的最高温度时间,相对湿度一天中的最高值早于气温中最高值的出现时间,但是同一隔离器内的温湿变化规律与空气内的变化规律相同;(3)有鸡隔离器内的CO2浓度远远高于空气中的浓度和无鸡隔离器内的CO2浓度;有鸡隔离器内的CO2浓度与鸡的活动量和取食时间有关,活动量小时CO2浓度小,活动量大时CO2浓度大,鸡取食时间CO2浓度大;(4)隔离器内的气象要素在一定程度上受外界环境的影响。This paper discovers the features of microclimate changing laws in winter isolator, points out reasonable adjustments for breeding of laboratory animals. We observe the variety of temperature, humidity and CO2 by three different kinds of treatments： A-isolator, B-isolator, and compare the results of observations. The result of experiment indicate： （1） there is close relationship between the activity amount of chicken and the variables of temperature.humidity and CO2 in isolator; （2） The changing law of climate factors in isolator is not consistent with that of air temperature： The highest temperature appears earlier than the air temperature, and the highest relative humidity appears before that of air temperature. While the changes of temperature and humidity in the very isolator is the same with that in air; （3） The C（）2 concentration in A-isolator is far higher than that in air and B--isolator, the CO2 concentration in A-isolator is related to the activity amount of chicken and the time of taking food： when less the activity amount of chicken, the lower CO2 concentration is, and otherwise; when the time of taking food, the CO2 concentration is higher; （4） Environment influence the isolator weather factors in a certain extent.
