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。

First, we have proved that the constraint of local constant gradient angles is equivalent to the minimization of total variation. Based on this, a stronger continuity constraint of gradient angle is presented. The interpolation formula (a 3-degree-PDE) derived from the constraint can ensure the continuity of level lines and reduce the width of edges. The contrast invariant of the regularizer of the formula is also proved.
首先证明了局部恒定的梯度角约束插值等价于总变分最小化;在此基础上,提出一个具有更强连续性的梯度角约束,由这个约束条件导出的三阶偏微分方程使插值的图像既可以保证水平线方向的连续性,又减小图像边缘的宽度;最后证明了插值方程中正则项的对比不变性。

The difference of mean intraocular pressure among readings obtained with the lens in place, after lens removal and lens reinsertion were not statistically significant in bandage contact lens group and in low myopic contact lens group. But the high myopic contact lens group showed statistically significant difference of mean intraocular pressure obtained with the lens in place, after lens removal and lens reinsertion. In addition, the intraocular pressure readings measured immediately after myopic contact lens reinsertion revealed poor reliability.关键词 Tono-Pen , Soft contact lenses
我们把受测者分为三组:低度近视组,高度近视组和配戴治疗性隐形眼镜组,每组分别以受测者未戴隐形眼镜时的眼压做基准,而以其他三种情形的眼压分别与之比较,结果发现以Tono-Pen测量低度近视组和配戴治疗性隐形眼镜组的眼压值可信度较高,但是戴上隐形眼镜之后马上测量的眼压值较不准确,而高度近视组的测量值则出现变异的现象,可信度较低。
