The spatial derivatives are discretized by DRP scheme,and the low dissipation and dispersion RungeKutta scheme is used for time integration. The Giles' characteristic 1D unsteady nonreflecting boundary conditions are applied to the inflow and outflow boundary regions.
The dispersion relation preserving (DRP) finite difference scheme is applied for spatial discretization and the low dissipation and low dispersion Runge Kutta(LDDRK) scheme is utilized for the time integration.
At room temperature the ceramics containing w(CeO_2)=0.1% possess high piezoelectric constant (d_(33)=199 pC/N),high electromechanical coupling factor(k_p=39.3%),and low dissipation factor(tan δ=2.0%) at 1 kHz.
At room temperature the ceramics which the starting materials were milled using ethanol as the media,sintered sealed at 1180℃ for 2h,possess high piezoelectric constant(d_(33)=195pC/N),high electromechanical coupling factor(k_p=35%),and low dissipation factor(tgδ=2.5%) at 1kHz.
The dramatically low dissipation factor of the specimen is explained by the reducing of Cr3+ to Cr2+ and the acceptor action of Cr3+ and Cr2+ which neutralized the donor action of oxygen vacancies.
Both ferroelectric BaTiO3-based and SrTiO3-based dielectric ceramics with high dielectric constant and low dissipation factor have been successfully developed, and applied into mass production for high-voltage ceramic capacitors.
Described here is a new style, cardiac pacing system—an implantable pacemaker with the programmability of parameters. It consists of a programmer and an implantable pacemaker with a digital memorial element. Whenever an adjustment is neccessary, the pacemaker can be manipulated to a new stable state with the programmer emitting a series of coded pulses toward it. The process of adjustment is quick and noninvasive.The pacemaker is made by combining a CMOS circuit with monolithic integralted circuits into a h...
TLMM thin film capacitors have firstly been manufactured by depositing PbO2 semiconducting film with MnO2 on Ta2O5 media. The characteristics of TLMM capacitor are low dissipation factor and small temperature coefficient shift. Auger spectra analysis shows that the least dissipation factor of capacitor is 0.1-0.3% (1kHz) and the temperature coefficient is 201.5±3.5ppm/℃(-40~70℃) when Pn: Mn: O = 30: 20: 50.
