Abstract
Official abstract text for this publication.
An occluded hydrogen content estimation method implemented by an occluded hydrogen content estimation device performs an occluded hydrogen content estimation step in which, based on an occluded hydrogen unit content which is a content of hydrogen occluded in a metal due to a change in humidity from a wet state to a dry state, a period after the metal is placed, and meteorological data corresponding to the period for an area where the metal is located, a content of occluded hydrogen that is absorbed in the metal for the period after the metal is placed is estimated. In the occluded hydrogen content estimation step, the occluded hydrogen content is estimated by multiplying the number of rainfalls in the meteorological data by the occluded hydrogen unit content.
First claim
Opening claim text (preview).
The invention claimed is: 1. An occluded hydrogen content estimation method implemented by an occluded hydrogen content estimation device, the method comprising: estimating a content of hydrogen occluded in a metal due to a change in humidity through at least one repetition of a wet state to a dry state to generate an occluded hydrogen unit content; determining a period after a target metal is placed in an area and determining meteorological data corresponding to the period for the area where the metal is located wherein the target metal is a same type is the metal, and estimating a content of occluded hydrogen that is absorbed in the target metal for the period based on the occluded hydrogen unit content and the meteorological data corresponding to the period. 2. The occluded hydrogen content estimation method according to claim 1 , wherein, in estimating the content of occluded hydrogen that is absorbed in the target metal, the method further comprises multiplying a number of rainfalls in the meteorological data by the occluded hydrogen unit content. 3. An occluded hydrogen content estimation device that estimates a content of hydrogen that is occluded in a target metal located in a predetermined environment, the device comprising: an occluded hydrogen content estimation unit that estimates, based on an occluded hydrogen unit content which is a content of hydrogen occluded in a metal of a same type as the target metal due to a change in humidity through at least one repetition of a wet state to a dry state, a period after the target metal is placed in the predetermined environment, and meteorological data corresponding to the period for an area in the predetermined environment where the target metal is located, a content of occluded hydrogen that is absorbed in the target metal for the period.
