Results showed that the hardness level of drying schedules had much influence on both the drying strain developed and the time when it reached its maximum value.
结果表明，基准硬度水平对应变值的大小和最大应变值的到达时间有显著影响。
However, with the increase of aging temperature, the hardness gradually increases, while reaching a maximum value then begins to decrease.
在相同时效时间条件下，随时效温度的升高，硬度逐渐增高，达极大值之后又降低。
