To measure the atmospheric optical turbulence, the microtemperature sensor is often used. But statistic average time can affect the measuring results of temperature structure constants. From analyzing the source data the average time can be set as 5~15 seconds. In the measuring period of microtemperature, the results will be erroneous when the environmental influence exists or the instrument state is not proper. Most of these situations can be found out from the source data analysis. One method of data differentiation was presented and discussed. First, error data was removed according to the experiment records. Second, if some data was abnormally large or small, the spectrum of source data of temperature difference was used to determine the facticity of data. These two steps could ens
