    摘要： The present invention relates to a method for the simple, objective and accurate determination the zero point or effective zero point of a material, the point of first contact between an indenter tip and the surface of a material. The zero point is determined by using a sensor having a tip and capable of continuous stiffness measurement. By applying a data shift, which insures that the stiffness versus contact parameter curve is linear and goes through the origin of the graph, it is possible to determine the zero point based on combined data from indentation and from superimposed continuous stiffness measurement oscillations.
