According to overall-process cost control of building project, the author introduces the measures to strengthen construction cost management of building project from the stages of decision-making, design, bidding, construction and completion, in order to fully use manpower, material resources and financial resources and to achieve well benefits.
This paper introduces the characteristics of steel fiber reinforced concrete,analyzes several basic mechanical properties of steel fiber-steel wire mesh concrete by lots of experiments,introduces its application in protective engineering,and shows by practices that this new composite material has well application effect and is worthy to be popularized.
Combined with practical engineering,this paper introduces the basic component,operating principle,technical performance and characters of HZS75B full automatic concrete mixing station,illustrates its operating technology,points out its construction notices,and proves by practices that premixed concrete technology has well application effect and is worthy to be popularized and applied.
The results showed that the power loss at specific dynamic deformation of rubber compound based on BR,SBR or their blends with NR,in which NR was taken as main polymer,was well correlative to tanδ at 60 ℃ measured by dynamic viscoelastic spectroscopy.
In this paper, we prove the degenerations of Schubert varieties in a minusculeG/P, as well as the class of Kempf varieties in the flag varietySL(n)/B, to (normal) toric varieties.
Well known wonderfulG-varieties are those of rank zero, namely the generalized flag varietiesG/P, those of rank one, classified in [A], and certain complete symmetric varieties described in [DP] such as the famous space of complete conics.
There are two well known combinatorial tools in the representation theory ofSLn, the semi-standard Young tableaux and the Gelfand-Tsetlin patterns.
It is well-known that the ring of invariants associated to a non-modular representation of a finite group is Cohen-Macaulay and hence has depth equal to the dimension of the representation.
As a corollary, we obtain a new proof for Roberts' well-known counterexample in dimension seven.
