Solution culture, subcellular fractionating procedure, electron microscopy examination and biochemical analysis were used to study the effects of calcium supply on subcellular distribution of cadmium, chloroplast ultrastructure and RuBPC and PEPC activity in maize seedlings under cadmium stress. Compared to no calcium supply under cadmium stress, calcium supply could significantly lower Cd content and increase Ca content in both organelles and cytoplastic fraction in roots and leaves of maize, while no such sighs were observed with cell wall fraction. In calcium supply treatment under cadmium stress, stroma lamellae in chloroplast of mestome sheath and grana and grana lamellae in mesophyll were better arranged, and much less osmiophilics appeared in chloroplast of mestome sheath, compared to that of no calcium supply treatment. It was also found that RuBPC and PEPC activity in leaves of maize under cadmium stress significantly increased by supplying Ca. It was concluded that calcium play a very important role in maintaning normal structure and function for plants under cadmium stress.

The change of X ray diffraction rocking curve and the lattice constant with the epilayer thickness in Hg 1- x Cd x Te film grown by liquid phase epitaxy(LPE) is studied by high resolution X ray diffraction method. The effect of composition interdiffusion on the rocking curve and lattice constant is observed in the experiments. The thickness of the interdiffusion region, which locates between the substrate and the epilayer, is about 2~3μm. In this region, the full width at half maximum(FWHM) of the rocking curve decreases, which indicates that the Zn element diffused from the substrate decreases the etching pits density(EPD) around the interface. Through the measurements of lattice constant, the depth distribution of Cd composition is obtained. The composition is lower on the surface but higher when approaching the substrate. The composition profile is nonlinear and accords with an exponential decay relation.
