摘要：

A difference scheme was proposed to calculate glow discharges with a time step DELTAt that is not limited by the inequality DELTAt < epsilon0/e\mu(e)N\, where epsilon0 is the permittivity in free space, e is the unit charge, mu(e) is the electron mobility and N is the electron density. Calculations were made with a beam model for helium dc glow discharges. The model predicted high-density cold electrons in the negative glow. Calculations were made with a DELTAt which was 50 times larger than the one limited by the above inequality for the proposed scheme; the value of DELTAt could be determined from a physical point of view.
