In modem electric power systems,a reasonable accurate representation of load is necessary for power system stability and dynamic analysis. Load modeling is one of the most important cause effecting the precision and credibility of the simulation result. For a long time, load modeling studies have been behind the development of the electric power industry. The basic theoretical knowledge of electrical...
The main research of this paper was on the effects of different microcuttage matrixes of taxue cuspidata upon rootting and seeding. Simplex-gravity mixing design was used to optimize microcuttage matrixes. Fifteen kinds of matrixes formula was obtained by combining four ingredients that were garden soil, river sand, sawdust and slag respectively. The growth condition of cutting shoot was investigated...
In order to balance the relationship of population, land and Grain in Liaoning Province, the relevant theories were summaried and analyzed, the characteristics of each theory and its shorting was pointed out. Based on feature research, the gray system model was built to forecast the development tendency of the balance between populations, the cultivated land and grain corps. Results show that before...
This paper presents a detailed analytical solution for a mathematical model of Emulsion Liquid Membrane (ELM) extracting hazard metal from waste water. By solving the resulting simultaneous partial differential equations using the Laplace transform method, we obtain formulas for solute (hazard metal) concentration in external phase (waste water) versus time, solute concentration profile inside the...
