摘要： A method and a system is provided for measuring mechanical properties of a solid material using standard ultrasonic wave modes propagated in the solid material, which forms a waveguide, where the waveguide is encased a fluid media. The method and system can be at high temperatures. The system includes an ultrasonic transducer placed at one end of the waveguide that generates multiple wave modes, which travel in different paths along a length of the waveguide and are reflected. The system includes a set of corresponding sensors for detecting the amplitude and time of flights, and includes a processor means to analyze the detected signals.

摘要： An apparatus for determining a type of a recording medium is provided. A detection unit detects a characteristic value indicating a physical characteristic of a recording medium. A measurement unit measures a moisture content correlated with a moisture content of the recording medium. A determination unit determines the type of the recording medium based on the moisture content and the characteristic value. The determination unit may correct the characteristic value using the moisture content or correct a rule for determining the type of the recording medium using the moisture content unit, and determines the type of the recording medium in accordance with the corrected characteristic value or the corrected rule.
