The fluid flows and heat coupled calculation method is used. The standards two equations turbulence models, velocity and pressure coupled arithmetic are used.According to the results of numerical simulation analysis the local coefficient distribution changes along the pin fins.Study the effection that its height and shape of the pin fins have on the average Nu and the average number of pressure loss coefficient Eu.The circle-shaped and elliptic-shaped pin fins have different circumcolumnar regional,therefore the mixed conditions are effected.

Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.
