The results show that dendritic segregation, banded segregation, liquation carbide and secondary carbide precipitated at the grain boundary or martensite lath are the main reasons causing the low impact toughness of H13 mandrel steel.

研究结果表明：枝晶偏析、带状偏析、液析碳化物及存在于晶界或马氏体边界的二次碳化物，是导致芯棒冲击韧性降低的主要原因。

However, there are still some disadvantages in zinc electrode, such as metamorphose dendritic growth, erosion, passivation etc.

但是由于锌电极存在变形、枝晶、腐蚀和钝化等问题，使得锌电极在用于二次电源时的性能降低，这也是锌电池在应用中存在的严重问题。

The chemical superheating in solid during recalescence has a more important effect on the remelting and coarsing of secondary arms than the solid-liquid interface tension.

再辉过程中固相化学过热对二次分枝重熔粗化的影响也远大于同期固液界面张力的影响。
