摘要: A measurement apparatus is disclosed in which a barrier separates a chamber into a first region and a second region. The barrier is of a known thickness, and it comprises holes having a known radius. Gas flow means provide a flow of a carbon dioxide in the first region and a flow of a nitrogen in the second region. A gas detector measures the concentration of carbon dioxide in the second region and a processor calculates the theoretical diffusive flux from one region to another based on the known properties of the through-holes. The processor is arranged to calculate a calibration parameter in order to relate the measured parameter to the theoretical diffusive flux, based on the known properties of the through-holes.

摘要: A measurement apparatus is disclosed in which a barrier (2) separates a chamber into a first region (10) and a second region (20). The barrier (50) is of a known thickness (T), and it comprises holes having a known radius (R). Gas flow means provide a flow of a carbon dioxide (12) in the first region (10) and a flow of a nitrogen (22) in the second region (20). A gas detector (28) measures the concentration of carbon dioxide in the second region (20) and a processor (32) calculates the theoretical diffusive flux from one region to another based on the known properties of the through-holes. The processor (32) is arranged to calculate a calibration parameter in order to relate the measured parameter to the theoretical diffusive flux, based on the known properties of the through-holes.

摘要: A housing for a microwave circuit is formed from a base made of metal matrix composite material and walls made of sheet metal. The base and the walls are joined together by diffusion soldering. Some holes to receive feedthroughs are formed at the junction of the base and a wall.
