摘　　要：以亥姆霍兹线圈为标准磁场源,通过公式B=K·I得到亥姆霍兹线圈均匀区的磁感应强度理论值,特斯拉计读数与磁感应强度理论值之差即为特斯拉计示值误差,相关文献在国内尚未见报道。本文全面分析了测量过程中的影响因素,并评定示值误差不确定度。Helmholtz coil as magnetic field source and the theoretical value of magnetic induction intensity uniform region is obtained by the formula B=K·I.Indication error is the difference between the Teslameter indication value and the theoretical magnetic induction value.And itt has not yet been reported.This paper comprehensively analyzes the influencing factors in the measurement process and evaluates the uncertainty of the indication error.
