    摘要： An X-ray Talbot interferometer includes a first grating configured to diffract X-rays from an X-ray source and form an interference pattern, a second grating configured to block a portion of X-rays that form the interference pattern, and a detector configured to detect X-rays from the second grating. An inspection object is disposed between the X-ray source and the second grating. The second grating includes a first shield grating portion in which a shield portion and a transmissive portion are arranged periodically at a first period and a second shield grating portion. The first period is expressed as ps×n×Ls/(Ls+Lf), where ps denotes a size of pixels that the detector has, n denotes a positive integer, Ls denotes a distance from the X-ray source to the first shield grating portion, and Lf denotes a distance from the first shield grating portion to the detector.

    摘要： A method and an apparatus for measuring dry mass flow rate for a biological material.—The method steps include conveying the biological material through a measuring station, scanning the biological material with electromagnetic radiation of at least two different energy levels, determining the amount of radiation transmitted through the biological material at said two energy levels, and summing, for each of sad two energy levels, the radiation transmission values over a time frame to summed radiation transmission values. Further, a wet dry mass flow rate is estimated based on the summed radiation transmission values for said two energy level. The moisture content of the biological material is estimated based on the amounts of radiation transmitted through the biological material. The estimated wet dry mass flow rate is scaled in accordance with the estimated moisture content of the biological material, thereby providing an estimate of the dry mass flow rate.

    摘要： A method and an apparatus for quantitatively determining the macroscopic thermal neutron absorption cross-section of a geological formation traversed by a borehole is disclosed. The method comprises the steps of irradiating the formation with neutrons from a continuous source in a neutron sonde and detecting through the use of dual epithermal and thermal detectors the resultant flux of both thermal and epithermal neutrons. Representative signals are then combined in a manner which best takes advantage of the physics of the interaction of neutrons with matter to produce a representation of the macroscopic thermal neutron absorption cross-section. Thus, a signal representing the ratio of the counts is derived from each like pair of detectors. The logarithms of the signals are then taken and combined in a linear combination.

    摘要： A gamma densitometer window is provided along with a method of fabrication thereof. The window comprises a plate of non-metallic, preferably gamma transparent, material having a first face and a second face opposing one another and having an outer edge defined therebetween. The window further comprises a metallic frame member fitted around the outer edge of the plate and adapted to pre-load the plate with a compressive stress that is sufficiently high such that the sum of the compressive stress, tensile stress and shear stress components generated in the plate under high-pressure conditions is always compressive. The method of fabrication shrink fitting the metallic frame member around the outer edge of the plate at a shrink-fit temperature such that the metallic frame member applies a compressive stress to the plate at any temperature below the shrink-fit temperature.
