Two improvements measurements pointed to the errors to calculating b values have been proposed:(1) to adopt the uniform absolute magnitude scale, seismic moment magnitude MW,(2) to discard the magnitude points for which the earthquakes absent and lose, and then to compute the b value using least square method to fit the data.

针对过去计算b值的误差，提出了两条改进措施：（1）采用统一的绝对震级标度-矩震级标度MW；（2）舍弃缺失地震次数的点，然后用最小二乘拟合求得b值，使b值计算较准确。
