As the widely used resin matrix and composites, two kinds of epoxy matrix and its CF/epoxy composite and GF/composite have different mechanics property under different temperature. The result shows that the thermal property of the composite mainly depends on the matrix. If the matrix can resist high temperature, its composite can also have high strength under high temperature. resin matrix composite, thermal resistance, thermal deformation coefficient, severity retentivity ratio

Based on the cognition, a method is developed to assess the retrievability of temperature and the distribution of the global retrievability with HIRS/3 and AIRS data in Jan and Jul are firstly given by using the NCEP reanalysis data. The results show that the retrievability of temperature is low in the upper and lower atmosphere, and high between 400 hPa and 850 hPa. In geographical distribution, the retrievabilities are low in the low latitude marine regions and in some regions in Antarctica, and relatively high in mid-high latitude regions and continental regions.
