The theoretical calibration curves for friction of plastic working was plotted and the exact position of the neutral layer of plastic flow was given in the solution.

It is required very often to make a standard curve during a chemical analysis.

Determination of crosslinking density and structure of cured EPDM by calibration curve;

Spectrophotometry of Toluidine Blue Method for the Calibration Curve of Heparin

This article has introduced a referential mode for uncertainty estimation in coatings laboratory, especially for uncertainty estimation as using calibration curve.

To the problems of the slope of the early period on log-log plot is more than 1 and the data of the middle period and late period is too discrete which makes the early period of theoretical curve can not be matched and too discrete middle and later data makes too difficult for interpreters to make acute analysis.

Then the time domain and frequency domain theoretical curves of the longitudinal vibration velocity of the pile head are calculated when there appears necking or fracture in the upper part of the pile.

By analyzing the discharge formulas of the seeping of isolated well among the homogeneous isotropic aquifer when the water level at the beginning is in horizontal and fixed state and no water is supplied from up and down of the well,relevant theoretical curves(well flow-functions) have been introduced.
