    摘要： This invention relates to a method of non-contact detection and identification of the type of different substances and mixtures as well as determining their characteristics as concentration, hardness, etc. The method comprises irradiation of the inspected object by a wave pulse or a series of such pulses; reception (1), amplification (2) and analogue-to-digital conversion (3) of the signal, formation of output detailing wavelet coefficients and output approximating wavelet coefficients by means of fast discrete wavelet transformation of the digitized signal, by means of Mallat's pyramidal algorithm and orthogonal base functions, filtering (7) of the output approximating and detailing wavelet coefficients up to preselected ones, comparison of the filtered approximating and/or detailing wavelet coefficients, in the capacity of recognition attributes with preselected respective reference coefficients by the classifying device (8), and according to the comparison result the presence and type is determined and/or the studied characteristics of the inspected object is determined.

    摘要： A continuous process for the manufacture of a polycarbonate comprises: combining an aromatic dihydroxy compound stream and a diaryl carbonate stream to form a mixture; controlling a weight or molar ratio of the diaryl carbonate to the aromatic dihydroxy compound by: measuring a sound velocity, Vs, in the mixture at an operating temperature of the controlling step; and determining the weight or molar ratio of the diaryl carbonate to the aromatic dihydroxy compound in the mixture; and adjusting a flow rate of at least one of the aromatic dihydroxy compound stream and the diaryl carbonate stream, if needed, to achieve a desired weight or molar ratio of the diaryl carbonate to the aromatic dihydroxy compound; and polymerizing the aromatic dihydroxy compound and the diaryl carbonate in the presence of a catalyst to produce the polycarbonate.

    摘要： An apparatus and a method for measuring a speed of sound in a fluid in a well bore may include a frame adapted to receive the fluid there through are provided. The apparatus includes an acoustic source mounted on the frame; an acoustic detector to measure a signal propagating through the fluid, the acoustic detector disposed proximate the frame at a known distance from the acoustic source; and a test circuit adapted to synchronize the acoustic detector with a signal propagating through the frame. A method to determine physical properties of a fluid in a geological formation including a shear wave anisotropy in the geological formation and the formation composition using the fluid density and the fluid speed of sound is also provided.
