<P>PROBLEM TO BE SOLVED: To estimate a corrosion rate at an arbitrary point with a high degree of accuracy. <P>SOLUTION: A function application part 14A identifies an optimal parameter with a minimum error between an observed corrosion rate measured at an observational point and an estimated corrosion rate, as a parameter, by applying temperature, precipitation, and the number of dew condensation days at the observational point that are obtained by calculating a weighted average of the temperature, the precipitation, and the number of dew condensation days at a first observation point on the basis of distance between the observational point and the first observation point, a sea salt particle amount at the observational point and the observed corrosion rate to an analytical function for calculating the estimated corrosion rate at an arbitrary point. A corrosion rate estimation part 14B calculates the corrosion rate at an estimation point, on the basis of the analytical function using the optimal parameter, from: the temperature, the precipitation, and the number of dew condensation days at the estimation point that are obtained by calculating the weighted average of the temperature, the precipitation, and the number of dew condensation days at a second observation point on the basis of the distance between the estimation point and the second observation point; and the sea salt particle amount at the estimation point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
