Abstract：
Microcanonical simultaneous multifragmentation statistical model was used to analyse the ALADIN caloric curue. It is indicated that each theoretical representative point located in the temperature plateau (temperature backhanding) of ALADIN caloric curve does not necessarily fall-down into the region of temperature plateau (temperature backhanding) of the caloric curve of corresponding projectile remnant (hot nucleus). Therefore, regarding the temperature Plateau in ALADIN caloric curve as an evidence of nuclear liquid-gas phase transition might be questionable.
