They are, the preparation of S 2OF 10 by preparative chromatography with adsorption/thermal desorption, the standard sample of S 2OF 10 gas prepared by exponential dilution and the gas chromatography/flame photometric detector(GC/FPD) determination of trace S 2OF 10 from an SF\-6 sample with quantitative calibration factor.

The correction factor (the ratio of true value to observed value) is 1.

Discussed the inaccurate analysis of content of the benzene in the gas caused by inacurate sampling connection, correction factor, exhales and and alysis time and gives the improvement measures.

Also the correction factor of groups was educed; the correlation coefficient of "one year old"Merino s day age and body weight, cashmere yield and wool length w.

Study on the determination and the correction coefficient of activity of lysozyme in infant milk formula;

The correction coefficient needs to be adopted to calculate the determinated value of work curve,it simplifies the operation,reduces error and enhances the accuracy and precision.

In the paper,the method on error-measuring in Controlling TSP using blank whole-process filtering film technique was introduced,Correcting the TSP measuring values of the low concentration and high Concentration by adopting the correction coefficient respectively.

Extrapolating model of correct coefficient in the dropvolume method for determination of surface or interfacial tension;

The curve fitting of correct coefficient in the drop volume method for determination of surface tension was carried out by means of Powell method and multivariate regression.
