摘要
本文用数理统计方法之一——t检验法分别对LYl2合金在自然时效稳定态下,对应于一定置信水平的电导率和硬度值进行了估算。其所得结果,为在实际检测中的应用提出了直接的判断依据。
The conductivity and hardness of LY12 alloy in the natural ageing stability condition are estimated corresponding with the level of confidence by means of one of the mathematically statistic methods t inspection method. The results can be regarded as direct judgement eriterion in actual inspection.
