Auxin, for instance, stimulates the rateof cell elongation, causes shoots to grow up and roots to grow down, and inhibits the growth of lateral shoots.
例如，生长素刺激细胞延伸的速度，促使芽和根生长，而抑制侧枝的生长。

Big ferrites and hot rolling texture are left behind in particle structures, Which leads the anisotropy of mechanics, so the tensile strength and elongationrate reduce.
含有粗大的铁素体晶粒和残留的热轧织构，引起力学性能的各向异性，导致了抗拉强度和延伸率的降低。

A new pass designing method on the basis ofelongationrate was given and an example is also presented.
