摘　　要：A two-dimensional model is suggested for calculation of thermal radiation and temperature profile on integrated four-nozzle surfaces of a spacecraft. Correlation between temperature increase with geometry and emissivity is obtained through comprehensive computation.Results of the correlation agree with data from three-dimensional calculation. Correlationsfor twin cylinders and plates with infinitive length are also proposed.A two-dimensional model is suggested for calculation of thermal radiation and temperature profile on integrated four-nozzle surfaces of a spacecraft.
