Differentiating force: the automatic spring tension testing machine indicates the difference of the minimum value of the effective resolution.
Residual height: the height of the object after deformation under the action of external force, H.
Variable shape: the relative displacement generated by the spring tension test machine spring along the direction of load, its deformation height (free height -- remaining height), denoted by delta H.
Spring stiffness: the load or torque required to cause the spring to produce unit length (keratin). K= (f2-f1)/(h2-h1) is expressed in N/mm.
