摘　　要：本文利用最小二乘法原理对CR-39塑料蚀刻径迹探测器中重离子径迹的重建方法进行了讨论,并根据径迹重建技术测量了400 A MeV20Ne与C,CH2,Al靶作用射弹碎裂的总截面,所得结果与其他能区实验结果在实验误差范围内一致.Based on the principle of the least squared 39 plastic etched nuclear track detector is discussed. Total method, the reconstruction of heavy ion track in CR- fragmentation cross-sections of 400 A MeV ^20Ne on CH2, C, and A1 targets are determined using this track reconstruction method, which is consistent with other experimental results within experimental errors.
