摘　　要：提出了用年积温度和年积温度当量、年积湿度和年积湿度当量、年紫外光总辐射量和年紫外光当量等表述一个地区一年中的气候条件。用于不同地区大气老化或使用老化的比较和计算。建立加速老化与大气老化 (使用老化 )环境条件之间的当量关系。The district climate was described as year accumulative temperature, year accumulative temperature equivalence, year accumulative humidity, year accumulative humidity equivalence, year accumulative UV(ultra violet) irradiant and year accumulative UV irradiant equivalence in this paper. These parameters were used to calculate atmospheric aging and in service aging among different districts. The equivalence relationship between the accelerated aging environment and the atmospheric aging environment was created in this paper, and some examples were cited in illustrating the equivalence relationship.
