| Abstract: | Simple formula from the least sguare method is demonstr-ated.Under the condition of the linearization,deviation formula is derivedIf the deviation is not allowable value,a simple calculating method wouldapply.The method and its deviation formula arepresented in the artiele.Also,the computational result shows that the method is effecitve and itserror is lower than other methods. |
