A method to evaluate some Fourier integrals is extended from two-dimensional (2-D) and three dimensional (3-D) spaces to n -dimensional ( n -D) space, which are often used in the elasticity theory of dislocations in quasicrystals. Some key formulae have been given.
A gold electrode modified with adsorbed thionine monolayer was investigated with ac impedance and cyclic voltammetry method. It was found there were some different redox properties for the adsorbed thionine depended on the different potential scanning rate. At the slower potential scanning rate...
The number of the limit cycles bifurcating in small quadratic perturbations of quadratic systems with an ischronous center is studied, it turns out that the cyclicity of the period annulus around one kind of quadratic isochronous center is two.
A new method for the coverage prediction of Cellular Mobile Radio (CMR) system is developed and its basic principle is presented. Unlike the Statistical Prediction Model (SPM) that estimates propagation loss by empirical formulas or the Deterministic Prediction Model (DPM) that reckons...
The irreversible modifying effects on Pst I of several inhibitors have been studied with the irreversible inhibition kinetic theory of single substrate reaction provided by Tsou, C. L. Pyridoxal phosphate (PLP), p-chloromercuribenzoic acid (PCMB), diisopropyl fluorophosphate (DEP), 2,3-diacetyl...
Mechanical characteristics of MO disk are vital for the designer of the drives and the manufacturers who provide the mass-product MO disks. So measuring mechanical characteristics is very significant. We compares the existing measuring methods and gives some novel measuring methods we adopted in...
On the basis of an introduction of the Wigner Higher-Order spectra (WHOS) and a general class of time-frequency higher-order moment spectra, the geophysical signal was analyzed using the higher order time-frequency distributions (TFD). Simulation results obtained in this paper show that the...
Transmitted power will decrease, cross-modulate distortion and inter-modulate distortion will be caused and antenna pattern will shift if transmitted antennas are fixed together. All these will lead to the alteration of area coverage. According to the basic theory of electromagnetism...
