In reaction-injection moldinga mixture of two or more reactive fluids is forced under high pressure into the mold cavity.Chemical reactions take place in the mold rapidly and the polymer solidifies.Various fibers such as glass,graphite,or boron may also be used to reinforce the materials.Structural foams are also produced by a similar methodusing an inert gasand resin mixture.The product consists of a rigid cellular(closed-cell)structure with a continuous solid skin as muchas 0.080 in.(2mm)in thickness.There are several methods for forming structural foams with density reductions as much as 40% from the solid structure.Because stiffness is proportional to the third power of the thickness of a part,for the same weight of material used,cellular structures are stiffer than solid plastics or metals.

This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.
