By combining fake tree-crown and fine granularity quad-trees into one tree with single root, max or min rate-distortion slope node finding scheme is transplanted from coarse granularity variable size block motion estimation algorithm ( CG-VSBM) to FG-VSBM. 细粒度可变尺寸块运动估计算法同粗粒度算法一样可以利用树结构的特点快速找到具有率失真斜率极值的节点。
The fake root may be induced by 2,4-D because 2,4-D can change the arrange of microtubule. 假根的产生是2,4-D诱导所致,其原因很可能与2,4-D能改变细胞微管排列有关。
