This paper mainly studied the key technology of weight and centre of gravity accuracy control of offshore structures and floaters, developed structural design of weight and centre of gravity data base and realized its main function by using VB and ACESS. And the tolerance distribution calculation formula of weight and centre of gravity of offshore structures and floaters was worked out by utilizing dimension chain principle. The dynamic adjustment and control method of weight and centre of gravity tolerance during construction was raised.

Moreover, we we sequenced the entire mitochondrial DNA control region from 17 charadriiform species, and found that the base composition and distribution of the variable nucleotide sites within the control region were similar to other avian species, but a series of short tandem repeated motifs in the 3' end of domain III made A nucleotides and length increased significantly. Phylogenetic analysis showed that these sequences could not well resolve the relationship among genus in Charadriiformes, but within genera maybe has some valuable phylogenetic information.
