波纹管的有效面积F_(φφ)是它的重要特性之一。众所周知,有效面积F_(φφ)中的数值具有高的恒定性,它跟位移和作用压力的关系极小。对波纹管在仪表中的大多数应用场合来讲,有效面积的上述性质是保证良好度量性能的必要
Bellows effective area F_ (φφ) is one of its important features. It is well-known that the value in the effective area F_ (φφ) has a high degree of constancy that is minimal in relation to displacement and acting pressure. For most applications of bellows in meters, the above properties of effective area are necessary to ensure good metric performance
