Abstract: The accuracy key to the deflection curve of a uniform section straight beam subjected to the moment is a circle,however,the answers are both parabolas by metheds of graph multiplication and double integral .The reasons are analysed,and the error is given with a parabola replacing a circle.

Key words: metheds of graph multiplication, metheds of double integral, pure beam, deflection curve
