The invention provides a method for acquiring fragment ion spectra of substances in complex substance mixtures wherein a trapped ion mobility spectrometer (“TIMS”) is used as the ion mobility separator separation device. The fragment ion spectra may be used for the identification of high numbers of proteins in complex mixtures, or for a safe quantification of some substances, by their fragment ion mass spectra in a mass spectrometer with up-front substance separator. TIMS with parallel accumulation provides the unique possibility to prolong the ion accumulation duration to find more detectable ion species without decreasing the measuring capacity for fragment ion mass spectra. The high measurement capacity for fragment ion mass spectra permits the repeated measurement of low abundance ion species to improve the quality of the fragment ion spectra.

When the coaxial connector in radio frequency is in connected state, gap of joint reference planes between male and female connectors is zero. At the same time, the coaxial connector can keep large axial directional contact pressure, and good axiality. There is annular bulge on surface of outer conductor of female connector. The annular bulge includes a bearing inclined plane. Dish shaped lock sheet with multiple teeth is setup inside male connector. When male connector and female connector are in connection state, the bearing inclined plane bears the lock sheet. Tangential force is generated between the lock sheet and the bearing inclined plane, and thrust is generated along normal direction at contact point of the bearing inclined plane. Thus, reference plane of female connector presses reference plane of male connector. Reducing volume and lightens weight, the coaxial connector is applicable to civil or industrial equipment, and areas of aviation and spaceflight.

The invention relates to the technical field of buildings, in particular to a reinforcement cage lifting part used for lifting a reinforcement cage in building. The reinforcement cage lifting part comprises a lifting rod and a connection lifting rod which are matched with each other in an inserting mode, the lifting rod and the connection lifting rod are half-cylinder rods, the wall of the lifting rod and the wall of the connection lifting rod comprise arc-shaped surfaces and planes, inclined catching grooves are formed in the center of the plane of the lifting rod, and inclined inserting lugs are arranged at the center of the plane of the connection lifting rod. A hook comprises a direct connection section, a bearing section and a specially-shaped free section, a lock catch hook is hinged to the direct connection section, the upper portion of the specially-shaped free section is provided with a pin hole in the direction perpendicular to the plane where the hook is located, the free end of the lock catch hook is provided with a pin hole corresponding to the pin hole in the hook, the specially-shaped free section is fixedly connected with the free end of the lock catch hook through a plug pin inserted into the pin holes, and the lifting rod is provided with a hoop piece which is used for clasping the lifting rod and the connection lifting rod. The reinforcement cage lifting part is simple in structure, low in cost, convenient to disassemble and assemble, capable of being recycled and long in service life. When the reinforcement cage lifting part is used, the reinforcement cage is little in shake, stable in lifting and safe to operate.
