Monitoring of the corrosion which plural electric resistance measurements (field signature method and electric resistant tomography) depends on expedient, induces the loss of the substance

摘要

The method of expecting the monitoring or corrosion of the corrosion which uses field signature method, crookedness and connection and in addition is offered the fact that it applies to similar and the like and the like non-linear position as purpose. As for this method, acquisition of the information which links the voltage measurement which is acquired in the position where it is during the electric contacting of two or more which contact with the position in first time and the other time of one or more when electric current passes position to the physical loss from position, is related is included. It is used with the model process which includes the model of the value which occurs in the voltage this the information which it is related will include the occurrence of the model of position, will include the point of two or more in that position, furthermore, first probably will be measured during the pointing two or more by the electric current which is applied to the position of second time at least. In order for loss of the substance from position to be modelled, the model includes the formal change of position with first time and second time. As for the relationship of this, relationship between the primary factor regarding model voltage value and form and/or the primary factor regarding the change of position is displayed.
