Graphite oxide, a pseudo-two-dimensional solid in bulk form, was synthesized from natural graphite powder by oxidization with KMnO4 in concentrated H2SO4. The poly(vinyl acetate)-intercalated graphite oxide nano-composite was prepared by an in situ intercalative polymerization reaction, in which n-octanol-graphite oxide intercalation compounds were first obtained, vinyl acetate monomer was then dispersed into the interlayer of modified graphite oxide, followed by thermal polymerization of the monomer. It was experimentally shown that the c-axis space of poly(vinyl acetate)-intercalated graphite oxide was increased to 0.115 nm, which suggested there existed a monolayer of poly(vinyl acetate) chain between the layers of graphite oxide. The nanocomposite was also characterized with thermal analysis and FT-IR spectrometry.

Effects of linear and solitary internal waves on the temporal correlation of matched- field processing （MFP） in shallow water are numerically investigated for acoustic sources with different frequencies and depths based on oceanographic data from an experiment. It is shown that the temporal correlation of MFP decreases as the amplitude of solitary internal waves or the average energy density of linear internal waves increases. For acoustic source with lower frequency or located below the thermocline, the temporal correlation of MFP is less affected by internal waves, and the temporal correlation length of MFP is longer. Moreover, the effects of the range from solitary internal waves to acoustic source on the temporal correlation of MFP are relatively small.

Symplectic Approach to Some Control Problems

1998年中国控制会议

作者： Daizhan Cheng (institute of Systems Science, chinese academy of sciences, beijing 100080, P.R.china)

＜正＞Some problems related to systems and control have been treated by symplectic geometric approach. First we consider generalized symplectic group and symplectic algebra. Then a generalization of Hamiltonian systems, namely, structurepreserving systems are considered. Finally, some propertied of control Hamiltonian systems are discussed.

We found that a small amount of iron can induce significant transformation of haematite into magnetite upon heating in ***,such a mechanism has to be considered for magnetic enhancement when conducting thermomagnetic analyses of environmentally polluted samples.
