| Abstract: | Through analysis,we know in linear range,that the relation between the strain ε of a point in the specimen and the ordinal number n of loading is linear,under the condition of equal increment loading.Applying the law of least square,an optimum straight line is fitted,then the optimum value of strain increment Δε is determined. |

| Keywords: | method of equal increment strain increment linear relation law of least square optimum value |
