核状结构灰色森林土

Nut structured gray forest soil

接枝后凹凸棒石的粒径明显增大，粒子中间颜色较深，周围颜色较浅，呈现较为明显的核壳状结构。

The diameters of attapulgite were enlarged obviously . The color was dark in the center while it was light around . The grafted particles presented a definite core-shell structure .

最后对晶体生长的特殊形成机制进行了研究，讨论了极性对成核和鱼刺状纳米结构生长的影响。

The special formation mechanism of crystal growth is discussed , emphasizing the effect of polar orientation on the nucleation and growth of the fishbone-like ZnO nanostructure .

第3种图像可见两个雌性原核和一个雄性原核，随着处理时间延长雌雄原核逐渐形成泡状结构。

And the third stage displayed one male pronucleus and two female pronuclei taking shape of bulliform structure with treatment duration .
