研究了具有非均匀权重分布样本的系统熵的计算方法．利用PYTHIA蒙特卡洛模型对两种常用的加权方案进行了检验，得到了较好的事件加权方案，并验证了其无偏性．

英文摘要：

We investigate the event weighting method in the measurement of the entropy on the data sample with nonuniform weight distributions. By using the PYTHIA Monte Carlo model, we test two common used weighting methods and find the valid one. The unbias property is also verified.
