Abstract：
The relation between the second order factorial moment and the number of participant nucleons in high energy induced nuclear reactions is deduced by taking account of the nuclear collision geometry. It is shown that in projectile fragmentation region of the high energy collisions the intermittent property of the final-state particles in hadron-nucleus reactions is dependent on the intermittent character of the sub-process of hadron-hadron collisions, but in target fragmentation region it mainly depends on the fluctuation of the number of participant nucleons. For nucleus-nucleus reactions (B << A), its intermittent strength is lower than that of hadron-nucleus reactions.
