On the basis of twin-roll thin strip continuous casting experiments and solidification structure characteristic analysis of thin strip and combining with the simulation results of effects of technological parameters, the forming mechanism of solidification structure zone (especially equiaxed crystal zone) on 1Crl8Ni9Ti stainless steel twin-roll thin strip was investigated.

在双辊薄带连铸实验和薄带凝固组织特征分析的基础上，结合对薄带凝固组织区的模拟预测结果，研究了1Cr18Ni9Ti不锈钢双辊薄带凝固组织区的形成机理。结果表明：1Cr18Ni9Ti不锈钢双辊薄带凝固组织中的等轴晶区不但在凝固类型为半固态时形成，在轧制或理想型时也能形成。其形成机理为，熔池中悬浮游离晶体的沉积、聚集以及在枝晶生长前沿的长大和薄带离开二铸辊最小间隙后，薄带/空气界面换热系数骤然降低抑制了柱状枝品的生长，并促使薄带中部未凝固熔体中游离晶体的择优长大

Results indicate that when the strain rate is 1200 s-1, the twin number of samples in different orientation increases with plastic strain increasing; when the strain rate increases to 2800 s-1, the σ-ε curves have no obvious charges as the angle is 0o and 45o, compared with that at 1200 s-1; however the σ-ε curves vary from concave to convex when the angle is 90o, because thermal softening has occurred with increasing plastic strain, which results in the number of twin decreasing, and smaller strain hardening

结果表明：当加载应变率为1200 s-1时，不同取样方向的样品中孪晶数量均随塑性变形应变量的增大而增多；当加载应变率增大到为2800 s-1时，取样方向为0°和45°、流变曲线形状较应变率为1200 s-1时没有明显变化，而取样方向为90°时曲线形状由应变率为1200 s-1时的凹形变为凸形，曲线形状变化的原因是由于应变量增大，热软化效应使得孪

The interclass co-twin correlations of blood glucose, and HOMA-IR of those twin pairs sharing 2 alleles of IBS were greater than those sharing 0-1 alleles of IBS. BMI, blood glucose and birth weight of those carrying the mutant C allele were higher, but the differences had no statistical significance.
