摘要

Temperature is one of the physical quantities through which quantitative evaluation of the safety and reliability of industrial products can be achieved, and this has been used widely in practice. Under any environmental condition, regardless of the size of the object to be inspected,accurate and reliable measurement of temperature is of great practical importance. This review article presents a simple and direct method of temperature measurement, that can be applied to the local areas with difficulty in measuring the temperature by using normal thermometers. In the present article,two different application examples are demonstrated. One addresses the study of the electromigration of solders which are used as bonding metals in electronic devices (micro-structures). The application of the method to the shaft of a motor used in heavy industrial fields is explained as the second.
