| Abstract: | The determination method of the calcium content in the calcium specimens using the microburette has introduced,and also has compared the obtaining results by the microburette and by the routine analysis.The relative standard deviation is less than 2.0%.There is no obvious difference in the results.F examination and t examination are all in the appropriate scope. |
