Answer the meansigma methods meansigma methods as total environment temperature of ambient temperature.
Such as: 11:00 ring temperature is 12 DEG C, 12:00 ring temperature is 18 DEG C, then the average ambient temperature of 11:00-1:00 is reduced to
(12+18)/2=15 DEG C.
Thus, by striding across the average ambient temperature of each actual environment temperature corresponding to value described in asking for, it can be correction
Operation provides more reliable foundation, and then can ensure that accuracy and the reliability of correction result.
Step S330, according to described correction ambient temperature, determines the described correction ambient temperature in described future time section
