查询词典 dimensional

The infrared radiation characteristics of unsymmetrically two dimensional nozzle are experimentally studied. UTDN is designed and manufactured by prolonging one broad side of a general two-dimensional nozzle AR8 and its aspect radio is 8. Temperature distribution on the axes and spectral IR intensity on the orientation of 0, 10, 30, 60 and 90° on three typical detective planes of the hot plume are measured on hot plume simulation platform of the turbo fan engine.

The conception of the edge element was firstly proposed by Whitney in 1957. At the beginning of 1980\'s, Bossavit and Verite put it to practical application to three-dimensional eddy-current problems. In 1987, Barton and Cendes applied the tetrahedral element to three-dimensional magnetic calculation.
