The technology of CAI and multimedia applied to physical education teaching can improe teaching effect,arouse students' interests in sports,renew physical education concept,upgrade teachers' capability of teaching,enhance students' enthusiasm,and speed up knowledge updating.
Compared with crystal materials, the excitation and emission spectra of Bi4Si3O12 nanopowders indicated a blue shift.
Direct determination of reserpine in urine using excitation-emission fluorescence combined with three-way chemometric calibratio
The concentration of reserpine in urine was directly and quantitatively measured by using the excitation-emission fluorescence (EEM) combined with three-way calibration methodologies.
Analysis and Design of Hybrid Excitation Permanent Magnet Synchronous Generators
On the basis of a conventional permanent magnet (PM) synchronous generator's construction, a novel kind of Hybrid Excitation Permanent Magnet Synchronous Generator (HEPMSG) is introduced by inserting exciting winding in the stator or rotor.
The spectra indicate that the energy transfer takes place from the triplet excited state of MLCT (metal-to-ligand charge transfer) state for Sr2CeO4 (sensitizer) to the rare earth ions (activator).
Research on a direct torque control for an electrically excited synchronous motor drive with low ripple in flux and torque
The electrically excited synchronous motor (ESM) has typically small synchronous inductance values and quite low transient values because of the damper windings mounted on the rotor.
Spherical harmonic series solution of fields excited by vertical electric dipole in earth-ionosphere cavity
The spherical harmonic series expression of electromagnetic fields excited by ELF/SLF vertical electric dipole in the spherical earth-ionosphere cavity is derived when the earth and ionosphere are regarded as non-ideal conductors.
NH4+ and NO3- could stimulate activity of aquaporins, and LP of roots in NH4NO3 solution was distinctly 77% higher than in distilled water.
Microelement preparations obtained in the course of processing flint powder stimulate the biological activity of Bifidobacterium adolescentis94-BIM grown on complex and synthetic nutritive media.
Addition of diesel fuel and waste engine oil to soil was found to stimulate hydrocarbon-oxidizing microorganisms.
It was demonstrated that melafen could both stimulate and inhibit the growth of potato tubers depending on its concentration and the physiological state of the tubers.
Low concentrations of phospholipase A2 and lipoxygenase inhibitors were shown to stimulate cell division, while higher concentrations inhibited it by blocking G1-S transition and inducing apoptotic cellular death.
The participation of cycloalkylthiolate ligand does not obviously arouse the change of the Fe4S4 core structure.
It is shown that not only the estrodiol set off the formation of pyrene bi-radicals, but also the pyrene radicals arouse conversely the production of estrodiol bi-radicals.
The mobile channel is slow fading and time selective, thus the multiplicative and additive noise of the channel will smear the spectral line, or arouse Doppler spread.
Data from the ADI on the first symptoms to arouse parental concern and on the first professional advice sought were analyzed.
The numeric result also provides a method to decide the most critical component which should arouse the system administrator enough attention to take the appropriate security measure or controls to alleviate the risk severity.
