1, meanwhile, when opposite side drawing-pressing spring is subject to the sedimentation load from the corresponding side of transmitting to its respective side taper bit, corresponding vertical survey chi monitor this side sedimentation and deformation value be d
2, the distance between the drawing-pressing spring of both sides is designated as L, and the distance of the drawing-pressing spring and tested point Q that are out of shape less side is M, then the settlement at Q place is δ
q=d
2+ (d
1-d
2) the M/L sedimentation and deformation value that is positioned at middle position C point is δ
c k=(d
1+ d
2)/2, the change of the Rayleigh scattering occurred based on wavy loopback fiber and Fresnel reflection, Brillouin scattering optical information, monitors that to be out of shape value be δ this moment
c o, initial deformation value is
then for same centre position monitor sedimentation difference absolute value be
for building the computing formula of native stone calmodulin binding domain CaM non-uniform settling, definition non-uniform settling parameter ω, and the expression formula of ω is defined as
based on this monitoring device principle of work and above-mentioned derivation, the final settlement computing formula at tested point Q place is
