Firstly, wettability and adhesive properties of the major soy protein components conglycinin (7S) and glycinin (11S) after urea modification were characterized. Modified 7S and 11S soy proteins were evaluated for gluing strength with pine, walnut, and cherry plywood and for wettability using a bubble shape analyzer. The molecular structure change was studied by chemical analysis, DSC and Rheometer. The results showed that different adhesives had varying degrees of wettability on the wood specimens.

The performace of material was tested by DSC,XRD,SEM,EIS and charge-discharge cycles . The influences of various synthesized condition , sintering time and the amount of F were studied and correlative technics parameter to improve performance of material were optimized. DSC shows that three endotherimc peaks and one large exothermic peak are observed in the temperature range 150-400℃, which is because of the removal of water,the decomposition of the organic constituents and the formation of spinel. Only the citrate precursor is sintered at least 450℃, the crystallinity of spinel phase could be formed intactly.

Due to the fact that the intercarrier spacing in OFDM is relatively small, OFDM transceivers are somewhat more sensitive to phase noise compared to single carrier transceivers. Thus this problem must be carefully considered in designing an OFDMbased system since an accurate prediction of the tolerable phase noise can allow designer to relax system specifications. According to spectrum theorem, two components of phase noise were analyzed: common phase error and intercarrier interference. On the basis of the analysis, the performance of OFDM was given for the case where phase noise has been added to the signal, and an optimal design criterion for OFDM parameters was proposed that allows to improve the phase noise error correcting capabilities in OFDM receiver.
