摘要： We propose a more effective fluid description on Vlasov-Maxwell (V-M) system. It is via an open set of off-center moments, which obey an open set of motion equations.This new description is of more advantage to give exact macroscopic information of the V-M system than the well-known moments-description. The new description implies that obtaining exact solutions of all moments is not necessary condition of obtaining those of self-consistent fields. 我们对Vlasov-Maxwell系统提出一更有效的流体描述。该描述通过一开放的偏心矩系列。该偏心矩系列服从一开放的流体方程组。与著名的矩描述相比，该新描述更具有优势去获得准确的V-M系统的宏观信息。该新描述意味着所有矩的准确解不是自洽场准确解的必要条件。
