根据YB-3航空有机玻璃海南自然老化1, 2, 3年后的疲劳寿命曲线和在东北沈阳-鞍山地区飞行使用5年后的疲劳寿命曲线，用疲劳强度降，建立了大气老化与使用老化两者的当量关系。并用YB-2航空有机玻璃海南大气自然老化与南方飞行使用老化的数据，验证了建立的加速当量的正确性和准确性。

The equivalence between natural aging and in-service aging was created in theory of fatigue strength degradation in this paper. It was done in terms of fatigue life curves for YB-3 Perspex aged for 1,2,3 years respectively in Hainan and aged for 5 years in Anshan district of Shenyang. The accelerated equivalence was provided correctly and precisely with the data of YB-2 Perspex aged naturally in Hainan and serving in flight in the south district.
