By applying electromagnetic vibration on solidification front of Sn-10Pb alloy,creation of equiaxed grain zone in ...

在低强度电磁振荡条件下，凝固组织细化和等轴晶化的原因是：电磁振荡力对金属初生晶的周期性拉伸、压缩、剪切、折弯、扭转等机械作用，使其出现断裂和剥落，增加形核数量；电磁振荡的局部搅拌作用使固/液界面前沿的温度和成分趋于均匀化，导致梯度降低，抑制了柱状晶的生长。

At the meantime time, through observing the fracture appearance of the silicon phase reinforced aluminum matrix composites, it was found that some equiaxial dimples exist at the position of the fine regular"primary silicon phase"but the tear appearance can be found at the position of eutectic silicon phase.

The eutectic temperature and the amount of proeutectic austenite dendrites are essentially unchanged with the variation of solidification rates in hypoeutectic white iron.

随凝固速度增加，亚共晶灰铸铁的共晶温度下降，初生奥氏体枝晶的数量和发达程度随之增加。

The primary sporogenous cells divided into the second sporogenous cells which would turn into microspore mother cells in a microsporangium. The cytokinesis in meiosis of the microspore mother cells was of modified simultaneous type, forming the decussate, isobilateral or T-shaped tetrads.

初生造孢细胞分裂形成次生造孢细胞，次生造孢细胞再转化为小孢子母细胞，小孢子母细胞减数分裂的胞质分裂为修饰性同时型，四分体排列方式为交叉型、对称型或&T&型，成熟花粉粒二细胞型，开花时散出。

And the long axis of simple pit Varied along with CMfs orientation of each secondary wall.This paper proposed a structure model of Phyllostachys pubescens cell wall,based on the results of CMfs deposition and thickness of each secondary wall.Secondly, it was a multilamellate structure of parenchyma cell wall,but its thin and thick lamellate was not evident.CMfs orientation on primary wall of parenchyma cell was perpendicular to cell axis.

纤维的细胞壁为典型的薄厚层相间的同心圆多层结构，初生壁CMfs排列方向与细胞轴向垂直90°次生壁中厚层的CMfs均以接近平行的小角度(0～5°沉积；薄层一般以大角度沉积，且薄层的CMfs角度由壁外侧向细胞腔里逐渐增加，直到完全垂直。

Most of such dendrite cores are distributed in the grains with an elliptical morphology; some of them lie in the grain boundaries with triangular or lathy morphologies. There are few dislocations and substructures in the dendrite cores, and there are clear phase boundaries between such dendrite cores and the matrix.

Ni合金过冷熔体中亚稳相和稳定相的竞争形核的计算与实验结果定性吻合，即当熔体过冷度大于某一临界过冷度时亚稳相将作为初生相从过冷熔体中析出，通过分析发现瞬态形核理论能更好的描述深过冷熔体中的竞争形核问题。

Minor Ce is found in pearlite and honeycomb ledeburite which transformed by the dendrite of primary austenite, while major Ce in ledeburite of lathy cementite type.

初生奥氏体枝晶转变形成的珠光体和蜂窝状莱氏体都含有较少的Ce，而板状渗碳体型莱氏体含Ce较多。
