According to the experimental information, the plane strain FEM based on the Biot consolidation theory, which based on the linear-elastic model, has been used to research the consolidation characteristic for the three kinds of strengthening methods.

In order to search after its applying to expressway roadbed improvement, this paper studied consolidation characteristic and distortion law hi soft soil under positive and negative action, introducing parse explain and numerical calculation theory.

The special consolidation deformation properties result in the engineering mechanics of "hard on top and soft underneath".

The paper summarizes the history of refractory elements addition,relates their influences on the solidification characteristics and microstructure,prospects the problems that still need to be solved and the future investigation trends.

Directional solidification characteristics of successfully shaped y-TiAl alloys is then presented and investigated in relation with the experimental parameters.

In order to obtain the natural frequencies and vibration,the inherent characteristics of interface structure is analyzed by simulating the actual working environment.

Effect of lithium on solidification characteristics of pure copper;

The casting temperature, casting speed, water flow rate of secondary cooling system and other process parameters are determined according to the solidification characteristics of 45 steel, such as low liquidus temperature, wide solidus and liquidus co-areas, low-strength slab shell under high-temperature, and to the existing equipment conditions of Caster 3.

The formation mechanism of TiC and TiB_2 particulates was studied,and the solidification characteristic of melting-pool of argon arc cladding was examined.
