Abstract: A four-shaft panoramic scanning temperature measuring device with a circulating water-cooling device is provided, which not only improves the working reliability of the probe, but also increases the overall flexibility and scanning measurement efficiency. The circulating water-cooling device is self-cooled. Compared with the conventional single-circulation water-cooling way, the design of five cooling cavities can achieve higher circulating water-cooling efficiency. The four-shaft structure includes a shaft structure for translation, a shaft structure for rotation, a shaft structure for swinging, and a shaft structure with coaxial sight pipe and light pipe. The design of the four-shaft structure is able to panoramically scan the high-temperature components inside the turbine. The temperature measuring device integrates functions of cooling, swinging, translating and rotating together, which solves problems of large size and complex control of the conventional temperature measuring device.

Abstract: A measurement and reconstruction method for a turbine blade strain field of with integrates an imaging technology and an infrared photoelectric measurement technology. The imaging technology is mainly responsible for the measurement of the strain field on a target blade surface, so as to use a digital image processing technology to obtain blade strain field data. The infrared photoelectric measurement technology is mainly aimed at the strain at blade edges, which uses temperature difference between the blade edges and blade gaps to perform strain measurement. Measurement results of the two modes are finally converted into blade strain parameters, thereby reconstructing the target blade strain field based on host computer software.

Abstract: The present invention designs a measurement scheme for the longitudinal temperature of the film during nitride epitaxial growth, belongs to the field of semiconductor measurement technology. Epitaxial growth technology is one of the most effective methods for preparing nitride materials. The temperature during the growth process restricts the performance of the device. The non-contact temperature measurement method is generally used to measure the temperature of the graphite disk as the base, which can't obtain the longitudinal temperature. The present invention respectively measures the surface temperature of the epitaxial layer and the temperature of the graphite disk by ultraviolet and infrared radiation temperature measurement technologies, and then uses the finite element simulation method to perform thermal field analysis from the bottom surface of the substrate to the surface of the epitaxial layer, so that the longitudinal temperature is obtained, thereby providing a favorable basis for temperature regulation during nitride growth.
