ANALYSES FOR DEFECTS OF 18G_2ANb STEEL SPHERICAL TANKS OF NATURAL GAS

Calculations and analyses are made with the CVDA, IIW, JWES standards for the strength and welding defects of two spherical tanks of natural gas in CHONG QING. The results of the analyses indecate that though there are some problems with the welding quality in these tanks, they may still be used with the desingned presure. Now the formal working of these two spherical thanks has verified of the validity the calculations and analyses.     

Finite Groups With 52 p Elements of Maximal Order

The authors discuss the finite groups with 52 p elements of maximal order,and get a theorem as follows: SupposeG is a finite group with |M(G)|=52 p elements of maximal order,where p is a prime and p>5,then G is solvable.     

A MORE GENEEAL PRODUCTIVE FORCES DISTRIBUTION MODEL WITH ENTROPY CONSTRAINT

The productive forces distribution model with entropy constraint is established. it satisfies both the demand with minimization of total cosls and the other demands with optimum distribution at a certain level. The model's regular optimal solution is a gravity molel..
