文章中提到：在钼基底上制备碳化硼涂层，由于钼的热膨胀系数比碳化硼大，涂层在1400度完好，但是在段烧至1600度时开裂

审稿人回复：请通过热膨胀系数解释为什么1600度开裂，而1400度不开裂？

审稿人原话：“Not clear that the thermal expansion coefficients explain the cracking at 1600 C and not at 1400 C.  Do the authors have detailed data on the thermal expansion of Mo and B4C as a function of T to back up their claim?  ”

请问各位大神，我这个该怎么解释呢？
