Results: Before intervention, the total scores, A (antisocial/disobey behavior) and N scores of the Ratter Parent Scale were of no difference. After intervention, the total subtraction scores (4.10±3.21), A subtraction scores (1.10±1.37) and N subtraction scores (1.32±0.91) in the intervention group improved significantly (P.05 -0.001), the recovery rate by clinical evaluation was 34%.

The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.

结果表明：经不同处理的Al-1Mn-1Mg合金均易发生动态软化并最终呈现稳态流变特征；热变形材料常数是过程量，随应变量的增加，应力水平参数α、应变速率敏感性指数m和热变形激活能 Q 随之增大，而应力指数 n 则逐渐减小；均匀化退火后，铝合金的α和m值最大而n值最小，动态软化效果最明显且变形均匀，在该状态下，铝合金的 Q 值受变形量影响小，平均仅为176.5kJ/mol，易进行热变形；当应变量为0.7时，基体呈现规则的再结晶晶粒组织，随着应变量的增加，晶内重新形成了位错胞结构。
