分级时效处理，低温下先让合金内部的宏观应力松弛，再在较高温度下时效，可有效地避免棒材纵向开裂。
However, stepped aging, which relaxes internal macro-stress under lower temperature then ages under higher temperature, can avoid longitudinal cracks effectively.
对温度预报进行方差、分级等统计检验。
As for temperature forecast, the variance and graded statistics have been computed.
采用分级淬火的方法测定了7055铝合金的温度—时间—性能(ttp)曲线，并结合合金实际淬火冷却曲线通过淬火因子分析方法预测了合金的硬度。
