摘　　要：通过测试不同厚度的试样和改变相同厚度试样的老化时间及温度来验证和分析试样厚度对塑性初值(P0)、老化条件对塑性保持率(PRI)的影响。试验表明,在其它试验条件不变的情况下,试样厚度偏大塑性初值(P0)也相应偏大,老化时间越长和老化温度越高,老化后的P30和塑性保持率(PRI)就越小。This article through test the different thickness’ test specimen and change the same thickness test specimen’s aging time and temperature to confirms and analytical the influence of sample thickness to the plastic starting value（P0） and the aging condition to plastic maintenance rate（PRI）.The experiment indicated,in other test condition invariable situation,test specimen thickness is larger the plastic starting value（P0） also corresponding larger,The aging time length and the aged temperature are higher,After aged P30 and plastic maintenance rate（PRI） is smaller.
