    • An objective of the present invention is to provide a rare earth metal-based permanent magnet with improved adhesion properties. A rare earth metal-based permanent magnet of the present invention as a means for achieving the objective has a laminated plating film, and is characterized in that the plating film comprises as an outermost surface layer a SnCu alloy plating film having a film thickness in a range from 0.1 μm to 2 μm, the composition of the SnCu alloy plating film is 35 mass % or more but less than 55 mass % of Sn and the rest being Cu, and a base plating film having two or more layers including at least a Ni plating film and a Cu plating film which are formed as the lower layer under the SnCu alloy plating film, and among the base plating film, the Ni plating film is located just below the SnCu alloy plating film. A joined structure fabricated using the rare earth metal-based permanent magnet of the present invention exhibits favorable initial adhesion strength when combined with a silicone-based adhesive, and is less deteriorated in adhesion strength even after a moisture resistance test.

    • A light emitter emits light with a plurality of wavelengths towards a test object held in a spectrophotometer tool. A light receiver receives the light passing through the test object. A detector detects absorbances of wavelength components from the light received by the receiver. An optical path length calculator compares, in the absorbances of the wavelength components detected, a wavelength component absorbance of light absorbed by a pigment that absorbs light with a wavelength other than a wavelength of light absorbed by an analyte in the test object and a predetermined value of the wavelength component absorbance to calculate an optical path length passing through the test object. A corrector corrects the wavelength component absorbance detected excluding the wavelength of the light absorbed by the pigment using the optical path length calculated by the optical path length calculator to calculate a corrected wavelength component absorbance in a reference optical length.
    • 光发射器向保持在分光光度计工具中的测试对象发射具有多个波长的光。 光接收器接收通过测试对象的光。 检测器检测由接收器接收的光的波长分量的吸光度。 光路长度计算器在检测到的波长成分的吸光度中,比较吸收被测试对象物中被分析物所吸收的光波长以外的波长的光吸收的光的波长成分吸光度和预定值 的波长分量吸光度,以计算通过测试对象的光路长度。 校正器使用由光程长度计算器计算出的光路长度,校正除了由颜料吸收的光的波长之外的波长分量吸光度,以计算参考光学长度的校正波长分量吸光度。
