图12 分子动力学方法计算的纳米金刚石和纳米孪晶金刚石压缩强度对比[48] (a) compressive strength of nc-diamond as a function of d (Maximum compressive strength is achieved with an average d of 8 nm) (b) compressive strength of nt-diamond as a function of λ (The continuously increasing strength with decreasing λ down to the minimum value 0.618 nm is noteworthy, the lines are guide to the eyes)
