【摘要】 在相同的实验条件下,相继用60KeV的Ni⁺和Ar⁺离子(剂量为10¹⁸ions/cm²)辐照同一块高纯石墨片,用高分辨透射电子显微镜（HRTEM）对包含Ar泡的碎片扫描得到TEM图像,并对纳米Ar泡的结构形态进行了分形维数的计算,为D_f≈2.36。更多还原

【Abstract】 In the same experimental condition, the same piece of high-pure carbon is irradiated one after another by Ni+ and Ar+ ions with 60 KeV. The TEM pictures of the fragment containing Ar-bubbles are obtained by HRTEM scanning. The fractal dimension of the nano-Ar-bubbles’ structure form is calculated. The result is:Df≈2.36.更多还原
