Shadow effect can not be neglected for thermal analysis of spacecraft,Accroding to the angle between solar light and antenna orbit plane and its orbit location,analytical geometry method was used for accurately calculating solar radiation heat flux distribution of reflector surfaces.To analyze the temperature field under heat flux,the formulations of net radiation flux density between two gray elements and the net flux density of gray surface under external thermal flux were deduced.Based on the characteristic of space environment,the nonlinear temperature distribution in transverse direction of reflector shell self radiation were considered,the finite element formulations were given for orthogonal material layered shell by Galerkin method.A layered element including a inner heat source layer was proposed,and the finite element formulation expressed by DOF of the inner heat source layer were put forward with temperature and heat flux boundarys between adjacent layer.

X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

The traditional ceramic semifinished materials are the aluminum silicate system, the production phase are mainly the mullite, the solid phase reaction temperature are quite high, generally in 1200℃ about; But after joining the wollastonite, turns the calcium silicate system, the high temperature resultant for the anorthite and the cristobalite, reduced the solid phase reaction temperature largely, approximately for 1000℃~1050℃, and the anorthite assumes acicular.

The results show that the glass-ceramics with fibroid structure is produced after definite heat treatment, the main crystallization phase is hedenbergite and anorthite is the minor crystallization phase. The optimal process of heat treatment shows as follows: the nucleation temperature is 850 ℃ and hold time is 100 min, and the crystallization temperature is 980 ℃ and hold time is 80 min. With increasing heat treatment temperature, the FT-IR absorption bands appear obvious split, the aluminum-oxide polyhedron in the glass network changes from [AlO4] to [AlO6]. The titanium ion in the glass network gradually transforms to the 6-coordinated, moreover forms minicrystal of MgTi2O5 and Fe2TiO4 which provides the position of heterogeneous nucleation for the growth of crystal.
