The laws of fluctuations in high energy heavy ion collisions werestudied with the multiplicitydistribution of EMU01 international collaboration. The dynamical factors dq and their ratios Dq≡dq/d1 were introduced to measure dynamical fluctuations quantitatively, and power scaling law between Dq and D2 was obtained. The exponents in the scaling were shown to be power scaling with q-1, and the scaling exponent γ was about the same for various collisions systems.%通过多重数分布研究EMU01国际实验组中高能重核束流与核乳胶相互作用中的动力学起伏的规律。引入多重数分布动力学因子dq及其比值Dq两个物理量来定量量度动力学涨落,得到了Dq与D2的幂次标度律,并且给出标度律中指数与q-1的标度关系,所得出的标度指数γ的值在各种碰撞体系中大致相同。
