摘　　要：利用多重分形矩分别在方位角空间和赝快度空间分析了3.7 A GeV16O诱发乳胶核(Em)反应产生簇射粒子分布的分形,得到在两空间中分维Dq基本一致,比较了在赝快度相空间得出的广义分维Dq与高能量下得到的结果,发现它们在误差范围内是相等的,说明簇射粒子分布的分维Dq与能量无关.The distribution of shower particles in 3.7 A GeV 16^O induced nuclear emulsion reaction is analyzed by using the fractal moments methods in azimuthal and pseudorapidity space. It is found the generalized dimensions Dq is consistent in two space, and the Dq calculated from pseudorapidity space is the same as the results at high energies within experimental errors. The result shows Dq is independent of projectivn energy.
