摘要： A method of X-ray based measurement of a multiphase flow components passing through a measurement tube comprises the steps of: directing a polychromatic photon beam generated by at least one X-ray source onto the measurement tube through which a multiphase flow is passed; locating a matrix detector behind the measurement tube along the beam, said matrix detector being a two-dimensional detecting structure comprising (mn) sensing elements and providing photon energy resolution, and exposing the measurement tube with multiphase flow by the X-ray pulses of a given duration and duty cycle; registering a polychromatic photon beam attenuated by said multiphase flow with an energy resolving matrix detector, whereas said matrix detector provides registration of a received photon beam according to different energy levels of the received photons and distribution of the received photons on energy levels according to spectral resolution of said matrix detector. A number of the energy levels registered by the matrix detector is defined as the ratio of maximum energy of the received photons to the spectral resolution of the array detector. A number of energy levels of interest is defined according to the number of components of said multiphase flow. For each X-ray pulse forming with the use of said matrix detector and in accordance with the defined number of energy levels a sequence of images of said multiphase flow, said images are characterized by pixel brightness; and determining from said formed sequence of images a volume content of each component of the multiphase flow basing on the value of the pixel brightness and in accordance with the law of absorption of X-ray emission. Then determining the flow rate of each component of the multiphase flow in the measuring tube in accordance with the cross-correlation analysis of the images formed by the matrix detector, and determining the volume flow rate of each phase of the multiphase flow as a product of the flow rate and the volume content of the phase.

摘要： An RF power combiner functioning as a higher-order harmonics filter comprises: at least one pair of coaxially arranged disc-shaped metal conductors, at least one of the conductors having a central axial opening to accommodate a waveguide is provided. Facing surfaces of the disk-shaped metal conductors are shaped symmetrically with respect to the plane of symmetry of the disk-shaped metal conductors to form a plurality of consecutive, radially communicating concentric cavities having isosceles trapezoids with different bases in section. The smaller base of each trapezoid disposed closer to the central axis. The number of the concentric cavities is (2 k+1), where K is the number of signal harmonics being filtered.
