On the basisof 3-D Finite Element Analyses of seepage fields in foundation pits, adopting theinitial flow method and the flux supply matrix, this paper conducts a series of 3-DFinite Element Analyses of the unsteady seepage fields of earth dam, with a newlycoded Fortran programme named SEEP3D.
The solubility of 2 -hydroxybenzoic acid was measured in supercritical carbon dioxide with and without cosolvents, such as cyclohexane and ethanol,within a temperature range of 308.15-328.15 K,and a pressure range of 10.0-24.0 MPa,by flow method.
The catalytic behavior, the magnetic property and the state of valence electron of Ag-Pd alloys have been studied with X-ray diffraction, magnetic measurement, flow method for measuring catalytic activity and X-ray photoelectron spectroscopy.
In order to completely eliminate the influence of thermal diffusion a new type of simple sample cell for determining the small surface area of powder and sintered compacts was designed and argon was used as absorbate, therefore the surface area as less as 0.01m~2 can be determined by continuous flow method.
After comparison of R&D project investment and traditional project investment, the paper explains that discounted cash flow method represented by net present value can't seize the whole value of R&D project.
The main orientation of theoretic research should be on the analysis of influential relationship between disaster and each factor based on field flow method, and the emphases is on the general law such as disaster mechanism and coupling among multiple disasters.
A setup for studying the thermal conductivity of powder samples in the temperature range 2-200 K using the stationary heat flow method is described.
The rate constants of second-order reactions of ozone with 22 substituted ethylenes in CCl4 solutions at 293 K were determined using the stopped-flow method.
The kinetics of the reactions of ozone with 12 substituted olefins in aqueous solutions at 293 K are studied by the stopped-flow method.
Results of Karzanov, Even, and Tarjan show that the blocking flow method constructs a maximum integer flow in this network in O(m min (m1/2, n2/3)) time (hereinafter, n denotes the number of nodes, and m the number of arcs or edges).
We show that, with a variant of the blocking flow method, this problem can also be solved in O(mn2/3) time.
