It was presented that there were different crystal mold and crystal structure of calcined calcium sulfate whiskers and the highest density crystal structure at 600 ℃.

The change of BNT crystal structure with that of parameter x was analyzed,and was compared with X-ray diffraction data of Ba6-3xSm8+2xTi18O54(BST) and Ba6-3xEu8+2xTi18O54(BET).

The variation in crystal structure and the transport properties of the sample were investigated through FTIR spectrum,Raman spectrum,ρ～T curves and ρ～T fitted curves.

An algebraic multigrid method for a class of discrete models of lattice structures;

Random seismic response analysis of long-span spatial lattice structure under three-dimensional and multi-support earthquake excitations;

The study of a rubber mould for lattice structure was presented.

Dielectric and ferroelectric properties of BaBi_4Ti_4O_(15) ceramics and their dependence on lattice structure;

Transmission electron microscope (TEM), Raman spectroscopy and X ray diffraction (XRD) were used to investigate the lattice structures, phonon properties of the samples.

The laws of the magnetic properties of granular films varying with the lattice structure have been studied.

On the basis of the affecting factors on the cellular structure of detonation waves of hydrocarbon fuels spraying in air,it can be concluded that a change in initial temperature shows a little influence on the cell size,while the cell size increases with the decrease of initial pressure.

Using time operator splitting technique and weighted essentially nonoscillatory(WENO) schemes to simulate detonation with detailed chemical reaction,we obtain its unique and regular detonation wave cellular structure.

According to the recorded cellular structure, the relationship between shock shock angles (the angle formed by trajectory of triple point and the slope of wedge) and wedge angles can be determined.
