So, in this paper, a circular cavity witha large radius is used to replace the straight boundary of thehalf space, then the half space problem can be changed tothe scattering problem of two circular cavities to the steadyincident P-wave . Having the aid of the mature cylinderfunction theory, the general solutions of the wave functionscan be given, and an infinite linear algebraic equations ofthe unknown coefficients in the wave functions can be gottenwith the boundary conditions and the Fourier complex seriesexpansion technology, the infinite linear algebraic equationscan be approximately solved by the finite trunction withsatisfying some definite precision, at the basis of thissolution of the equation, the variations and the lay-outs ofthe DSCF at the circular cavity boundary vs. the differentincident angles, the different embedded depths of thecircular cavity as well as the different dimensionless wavenumber of the incident P-wave.

ABSTRACT: Random amplified polymorphic DNA was used in analysing the relationship among twenty-six speices of Amanita from Mangshan, Hunan. Of 40 primers, 6 ones generated reproducible RAPD profiles, and each one produced 1-10 bands. Two primers (OPG15 and OPH04) could differentiate 26 species of Amanita by its RAPD profiles. The similarity coefficients obtained from profiles generated by six primers among Amanita were about 20-60%. A dendrogram was constructed using average linkage clustering for clustering analysis. It indicated that there were two groups in 26 species and some species with ring and membranous volva clustered a group which coincided with morphological classification.
