METHOD OF DECREASING ERROR OF DIRECT MEASUREMENT OF VALUE OF SURFACE STRESSES OF HYGROSCOPIC MATERIALS DURING HYDROTHERMAL TREATMENT

摘要

A method of decreasing the error of direct measurement of the value of surface stresses of hygroscopic materials during hydrothermal treatment is performed directly by compensation of the difference of deformations on the surface of hygroscopic material and the standard sample during bringing of external mechanical load to the standard sample. The difference of the values of deformations in the material and standard sample is controlled for the purpose of decrease of error.
