But the vegetations changes in plain zone were slower.(4) Study on the driving forces and driving mechanism of the change of vegetation cover in HHH zone The farmland vegetation area received the common drive of climate and the society factors, but climate factors were the main driving forces for annual harvest crop or biannual irrigated and dry harvest crop, and society factors were the main driving forces for biannual harvest crop or biyearly tri-harvest dry crop.

4黄淮海地区植被覆盖变化驱动力与驱动机制研究不同植被覆盖类型，其NDVI变化的驱动力不同：一年一熟粮作区植被覆盖变化受到气候和社会经济因子的共同驱动，但以气候驱动为主；一年两熟或两年三熟旱作区植被覆盖变化受到社会经济和气候因子的共同驱动，但在主要驱动因子中，社会经济的影响更大一些；一年水旱两熟粮作植被覆盖变化主要受气候因子驱动，同时，社会经济因子也会在一定程度上影响植被NDVI的变化。

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
