Dear Xueliang Zhang, I agree with Yoshitaka. You can certainly prime any complex component of a complex tone. The shorter the temporal gap between the two tones, the better the decomposition of the more complex one. Consider the extreme case, where there is no temporal gap between the two tones, and the more complex tone has just one more harmonic than the less complex one. What you will hear is a continuous drone of the less complex tone, with a pure tone (the extra harmonic) switching on and off periodically.
