The composite powders consisted of Si, Ni, Ag and a series of Si-Ni alloys. The SEM and TEM results showed that the composite powder consisted of clusters with space and network structures. The composite electrode exhibited higher reversible capacity and the initial columbic efficiency was up to 87 %, which was much higher than that of the pure Si electrode.

On the basis of electrical network characterization, Chapter 5 presents a new principle to detect PCB's fault first time. Three methods of online test for electrical network characterization are described in detail. Then, a hierarchical, combinatorial approach is firsfly presented. The test efficiency of this method is studied also. The experiment result shows that the new approach can greatly enhance the test efficiency of fixtureless tester under the requirement of 100% test for PCB's connections.

This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.
