Abstract
PURPOSE: To take an accurate measurement by measuring a diffusion coefficient by measuring concentration variation at a measurement point in a diffusion system and then by performing the Laplace integral processing of this measured value while setting properly a Laplace parameter and measurement time.
CONSTITUTION: At a measurement point in a diffusion system, concentration variation is measured as the function of time and Laplace-integrated to measure a diffusion coefficient through Laplace transformation of the 2nd Hook's law. The measurement point can be fixed at three points in the diffusion system, at two points or at one point of ∞. The product of the Laplace parameter and measurement time is preferably set to 8W12.
