The noncrystalline film WO _8by sol-gel electrophoresis has been described in this paper. The film can be dyed in dark-blue from almost transparent when the ions H~+(and/or Li~+) and electrons are double injected into it after an appropriate heat-treatment. Its electrochromic properties are: colour constrast C_R≈2:1 for response timo t_(res=1S,signal storage time at open circuit t_?=64h, and cyclic lifetime n=8×10~4 times. The experiments are carried out in a reversible bartery constructed by carbon/2 methy sulph-oxide+LiClO_4(liquid electrolyte)/WO_3/ITO. The effects of heat-treatment conditions, testing voltage, and film thickness on the structure, water content, optical density variable, cyclic lifetime, colour reversibility and signal keeping characteristics of such film are also discussed.

Based on clear physical concepts, complete nonlinear dynamic equations of two-phase media are derived by using classic mechanical principle directly. Then, two conditions under which the nonlinear equations can be linearized are expounded. The conditions are that varieties of the porosity and density with spatial position are much smaller than those with time in the dynamic process, and alterations of the displacement and pore fluid pressure induced by porosity or density changes can be omitted. Thus, the variables of displacement and pore fluid stress are decoupled with porosity and density variables, and can be resolved independently. Furthermore, the inconsistency that the porosity and density keeping constant is in contradiction with the compressible pore fluid and deformable skeleton assumption in two phase models (including Biot′s) is also clarified through linearization. After comparing some two phase models, the following conclusions are obtained. Firstly, the only differences between them lie in the constitutive relation; secondly, the soil mechanics′ model is a special case of the Biot′s and Zienkiewicz′s model.
