A direct method to prepare nanometre catalyst of positive electrode for methyl alcohol fuel battery is to add strong oxidant to a mixed solution of manganese nitrate and some other metal nitrate, to coat them on the graphite electrode to have catalyst precursor produced, then to prepare the non-platinum nanometre catalyst of metal ion-doped manganese dioxide with carbon as a carrier by thermolytic reaction of the in-situ precursor. The prepared catalyst has the advantages of high electrical catalytic activity of methyl alcohol, high performance to protect against CO poison and low price, and it can lower the battery manufacturing cost effectively as well as can raise the entire electrical property of the battery so that the price performance and the market competitive edge of the battery are enchnaced effectively.

This problem is also important and valuable in Nonlinear Optics. It will be very helpful to understand how the aberrations affect the course of three- wave mixing, such as the change of conversion efficiency, the distribution of intensity and phase.Small signal solution of aberrated second harmonic generation is deduced from three-dimension three wave coupling functions. The numerical work gives out lot of results of different aberrations. The effects of the fundamental waves aberrations, which will change the conversion efficiency, distribution of intensity and phase in the frequency conversion, is analyzed. It shows that when walk-off and diffraction effects could be ignored approximately estimation of the phase distribution of second-harmonic wave could be done. The far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave, but the far field divergent angle will be obviously smaller than that of fundamental wave. The phase distribution of both fundamental and harmonic wave is measured using Hartmann-Shack wave front sensor in the experiment with 1064nm and 790nm lasers, respectively. Results are given.
