| 摘 要： | 利用强子-强子碰撞的模型PYTHIA以及核-核碰撞的模型RQMD比较了各种电荷起伏测量量的快度依赖性，结果发现，这些测量量对快度的依赖性依赖于模型. 但是，电荷关联能很好地测量整体电荷守恒以及短程快度关联性质. 因此，被认为是一个好的反应电荷起伏的测量量.

| Abstract: | The dependencies of all suggested measures for charge fluctuation on the size of rapidity window are compared by using the hadronic and nuclear collision models--PYTHIA and RQMD. It is found that such dependency is model dependent. However, the charge correlations have the best measure for the effects of global charge conservation and short-range rapidity correlation and is therefore recommended. |
