Comparative Study on Several Evaluation Methods of Storage Life Characteristic Parameters
In this paper,the T-test,gray relational analysis and degradation rate calculation are comprehensively analyzed from aspects such as application conditions and tools required for implementation.It is concluded that all the three methods can effectively identify storage life characteristic parameters.T-test application condition is strict,but the application time is long,easy to accept,and ready-made tools are available.Gray relational analysis requires a lot of work to collate data,but has no application prerequisites,and can simultaneously obtain storage life characteristic parameters and optimal influencing factors,making it especially suitable for the analysis of small sample data.The calculation of degradation rate requires no preconditions and is simple,making it a good evaluation method.
