Claim 2:
3. The compensation method according to claim 1, wherein, during the time series matching process in step 2, the process data of a 2 hours duration is divided into 3 parts of 40 minutes in duration each, and an average value of the process data in each part corresponds to laboratory data of the previous sampling;
wherein a formula for the time series matching is:, {
