图6. 模拟的调幅分解波长和振幅随热老化时间的变化，图中星形为CF3M双相钢的实验结果[7]。注意此处c0=27.38%(原子分数)，cNi=5.42%(原子分数)，T=623 K

Fig.6. Simulated wavelength (a) and amplitude (b) of the Cr concentration fluctuation as functions of ageing time, compared with experimental values (CF3M, star symbols)[7]. Note c0=27.38%(atomic fraction)，cNi=5.42%(atomic fraction)，T=623 K in this case.
