用于确定物体的密度和尺寸特征的方法和系统以及在制造期间检查核燃料颗粒的应用

Method and system for determining the density and dimensional characteristics of an object and application to checking of nuclear fuel pellets during manufacturing
Abstract:
The system for automatic determination of the density of an object (100) comprises: an apparatus (2) to determine a significant dimension (x) of said object (100), an apparatus (30) to determine the intensity (I) of a photon beam attenuated by passing through said object (100), an acquisition, processing and analysis apparatus (200), means (70, 72, 80, 82, 84, 86, 88) of transporting the object (100), first means (74, 76, 78) of adjusting the position of the object (100), second means (90, 92, 94, 96, 98) of adjusting the position of the object (100). The method for using the system described above includes steps to calibrate components of apparatuses 2 and 30, and steps to actually determine the significant dimension of objects (100), that are done on each object (100) in said set of objects.
Abstract(Chinese):

用于自动确定物体（100）的密度的系统包括：用于确定所述物体（100）的显着尺寸（x）的装置（2），用于确定所述物体（100）的强度（I）的装置（30） 通过所述物体（100）衰减的光子束，采集，处理和分析装置（200），传送物体（100）的装置（70,72,80,82,84,86,88），第一装置 调节对象（100）的位置的第二装置（90,92,94,96,98），调节对象（100）的位置。 使用上述系统的方法包括校准装置2和30的组件的步骤，以及实际确定在所述对象集合中的每个对象（100）上完成的对象（100）的重要维度的步骤。
