The results show that the interplanar crystal spacing and lattice index of Al-rich α phase reduce gradually with increasing pressure. When the pressure reaches from common pressure to 5 GPa , Al-rich α phase lies on the (200) and (220) crystal faces, the interplanar crystal spacing are reduced by 1.07% and 1.15%. From common pressure to 3 GPa , the microstructure of ZA27 alloy changes from thick dendrites to fine dendrites, and finally to granular. According to the effect of solute diffusion coefficient under super high pressure and the calculation of Scherrer formula, it can be seen that the crystal organization is fine within the bounds of certain pressure. This conclusion is consistent with the experiment results.

The results from electron micrographic analysis show that soot oxidation is influenced by aggregation and agglomeration of soot particulates, at the same time, the crystallograms show that the previous soot particle is non-crystal carbon, but in the latter conbustion period, a very small amount of crystal soot with unstable lattice at relatively higher flame temperature is formed. The crystallization happens greatly in period of combustion when temperature is relatively lower. The smoke particulates consist of crystal carbon similar to chaoite crystal latice and noncrystal carbon.

The many lattice twist and dislocations can be observed by the studies on high-resolution electron microscopy of solution-crystallized PEKK crystals. It is the lattice twist and dislocations within crystals that give rise to gradual branching and narrowing of spherulitic lamellae towards to tips of crystal growth and consequently, the characteristics of morphology and crystal structure of poly s can be posed in the molecular level.

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.
