利用激光扫描共聚焦显微技术和碱性单细胞凝胶电泳技术对经过离子注入后的黑松花粉粒内细胞核的直接损伤效应进行了观察鉴定.研究结果表明,离子注入后可以直接损伤细胞核结构,导致细胞核裂解.细胞核的损伤程度与注入离子的剂量密切相关,即细胞核DNA分子的损伤程度随着注入离子剂量的增加而提高.

The butterfly martensite nuclei in an Fe-Ni-V-C alloy were observed under TEM,they con- sist of enveloping dislocations with Burger's vector(1/2)[]_(fcc) and arrays of dislocations with Burger's vector(1/2)[10]_(fcc) piled up within the former.The enveloping dislocations and the arrays of dislocations provide the required shear when the planes(11)_(fcc)move with each other to alter their stacking order and change into the planes(110)_(bcc) respectively.The necessary adjustment of the spacings is provided by the dislocations in martensite.The crystallographic relationship after double-shear is K-S one.
