in partial aerated flow area velocity distribution are similar on the first section and the difference between aerator and self-aeration is increase as the flow go downstream, and aerator makes velocity bigger than self-aerated flow;
Shanmei Reservoir is a large,multi-functional water conservancy project which put in to operation in1972.Based on the defor-mation observations of the dam during the30years,this paper analyzed the partial defect of the project and pointed out the evaluation and suggestion.
The paper combines the two methods to establish the method of coupling model with neural network and projection pursuit based on partial least-squares regression to predict the city water resources capacity,the model was found to be able to give satisfactory effect.
In accordance with the structure style of Zipingpu 1# and 2# diversion plug and the nearby surrounding rock' condition, the integral 3-D calculation model of diversion tunnel, spillway tunnel, concrete plug and surrounding rock is established and 3-D elastic and plastic finite element method is used to study the deformity, stress distribution as well as the safety of the partial and integral stability against sliding of concrete plug and surrounding rock.
Moreover, during the process of producing equation, the concepts of the total derivative and the partial derivative are confused. These all are the basic reasons the continuity equation cannot satisfy the steady flow condition.
We also compute the Euler characteristic of the space of partial flags containingnt and give a connection with hyperplane arrangements.
Then theG0-orbit structure ofZ is described explicitly by the partial Cayley transforms of a certain hermitian symmetric sub-flagF?Z.
Semi-invariants of quivers can be constructed by taking admissible partial polarizations of the determinant of matrices containing sums of matrix components of the representation and the identity matrix as blocks.
We define a partial order on the set No,c of pairs (O,C), where O is a nilpotent orbit and C is a conjugacy class in A(O), Lusztig's canonical quotient of A(O).
We also give formulas for intersection pairings on resolutions of singularities (or more precisely partial resolutions, since orbifold singularities are allowed) of the quotients.
