A multi-physical field measurement device for a metal solidification process and a housing and a measurement method thereof are provided. The device includes: a sealed housing provided with a light-through hole; a heater provided inside the housing and located behind the light-through hole along an X-ray; a diffraction detector used for receiving the X-ray which penetrates through a sample sheet and is scattered; a CMOS camera located behind the heater along the X-ray () and used for receiving a visible light signal which penetrates through the sample sheet; a silicon drift X-ray detector located at one side of the X-ray and used for receiving a fluorescent signal sent by interaction between the X-ray and the sample sheet; and an infrared thermal imager located at the other side of the X-ray and used for receiving an infrared signal sent by the sample sheet.

Multi-physical field measurement device for metal solidification process and housing thereof, and measurement method

A data reduction method and apparatus are provided to improve data reduction performance. In the method a storage device obtains a first service type of first data stored in a first logical unit. The storage device processes the first data based on a first data reduction manner that matches the first service type. The storage device obtains a second service type of second data stored in a second logical unit. The second service type is different from the first service type. The storage device processes the second data based on a second data reduction manner that matches the second service type. The first data reduction manner includes data compression and/or data deduplication. The second data reduction manner includes data compression and/or data deduplication. The first data reduction manner is different from the second data reduction manner.
