A characterization method for the solubility of ionic liquid is applied under atmospheric pressure for testing the function among ionic liquid and gas/gas molecules of volatile organic solvent, which is characterized by comprising: using an object ionic liquid as the sensitive film coat material of a resonator induction zone of a mass sensitive piezoelectric crystal detector; coating an ionic liquid film on the surface of the resonator induction zone; detecting the frequency change of the detector before and after acting with researched gas molecules to represent the function between the researched ionic liquid and the gas. The ionic liquid characterization method can obtain the solubility of ionic liquid in gas/volatile organics, and thermodynamic parameters as enthalpy, entropy, free energy change and the like in dissolution; and can research the function approach between ionic liquid and gas molecules. The measurement method is simple, fast and reliable, which can accelerate the development and application of ionic liquid.

The invention discloses a non-contact detection method for detecting the elastic parameter uniformity of a material on line. A non-contact real-time characterization method is used for the elastic parameters of a solid material, and comprises the steps of: (1) radiating pulse laser to a spatial modulator, generating two beams of coherent light after the pulse laser passes through the spatial modulator; wherein the laser source is a nanosecond or a picosecond pulse light source, the pulse light is split through the spatial modulator consisting of gratings, and the +/- level serves as a coherent light source; (2) radiating the two beams of coherent light to the surface of the tested material and generating spatial coherent interference field by utilizing an optical component lens group, forming alternately dark and bright interference fringes on the surface of the tested material, wherein the distance between the alternately dark and bright interference fringes is acquired by adjusting the lens group or the gratings; and (3) generating sound waves of which the wavelength corresponds to the distance between the interference fringes in a thin-film material after the interference fringes formed by the pulse light source are absorbed by the thin-film material, and performing non-contact detection for characterizing and analyzing the elastic parameters of the solid sample.

The invention relates to a characterization method for the strengthening phase of a ferromagnetic alloy block and/or film. An optimum scheme includes: separating a strengthening phase of nano to micron size in a ferromagnetic alloy from an alloy matrix to obtain an electrolyte solution containing the strengthening phase; then conducting dilution by anhydrous ethanol and ultrasonic dispersion, thendripping the obtained solution to an ultra-thin carbon support film, and performing drying to obtain an electron microscope sample; and then using an electron microscope for structural observation and characterization. The method provided by the invention can characterize the morphology and structure of the strengthening phase less than 0.5micron in the ferromagnetic alloy, especially the strengthening phase less than 50nm in size. The strengthening phase separated by the method provided by the invention retains the original structure of the strengthening phase, and the method has the advantages of simplicity and high efficiency, easily available electrolytic conditions, simple operation and strong repeatability, and can be used for analysis and characterization of strengthening phases invarious ferromagnetic materials. The method provided by the invention effectively avoids the adverse effects of ferromagnetic alloy matrixes on electron microscope equipment and the detection process, and realizes the TEM/HRTEM structural characterization of the ferromagnetic alloy strengthening phase.
