查询词典 earthquake magnitude

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。

Methods Keratometric reading with Topcon KR-8100 automatic keratometry and comeal topography with the TMS-4 on 53 ametropia' children, 106 eyes were compared. Difference in measurements of steep meridian power magnitude Ks, flat meridian power magnitude Kf, astigmatism magnitude Ks-Kf and location as well between the two methods were assessed using paired t test.Bland-Altmann method was used to evaluate the agreement of the two methods.

采用KR-8100自动角膜曲率计及TMS-4角膜地形图仪对53例（106只眼）屈光不正儿童进行测量，应用配对t检验对两种方法测量的陡峭子午线角膜屈光力、平坦子午线角膜屈光力、角膜散光Ks-Kf大小及轴向进行比较，并应用Bland-Altmann分析对两种测量方法进行一致性评价。
