Results from simulation show that the circuit has a forward power gain of 15.67 dB,a noise figure of 2.88 dB,an IIP3 of-0.21 dBm,and a power dissipation of 25.79 mW.
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.
The preferred orientation, dielectric constant, dielectric dissipation, breakdown strength and leakage current density do not follow a clearly regular trend when the V(O2)/V(Ar+O2) is varied from 0 to 0.5. The optimal figure of merit is 5 μC/cm2 at a V(O2)/V(Ar+O2) of 0.1.
The ZnNb2O6 ceramics doped with mass fraction of 0.25% CuO and 0.25 % V2O5 sintered at 1 025 ℃ have the optimal dielectric properties:dielectric constant εr = 35, dissipation factor tanδ =0.000 21,temperature coefficient of resonance frequency τf = – 44.41×10–6/℃.
3. Based on Biot's consolidation theory, computer program 3DBCPE3.0 was developed by 3-D FEM that can be used to perform the coupled analysis of soil mass deformation and pore pressure dissipation.

In the present paper, we deal with the long-time behavior of dissipative partial differential equations, and we construct the approximate inertial manifolds for the nonlinear Schr?dinger equation with a zero order dissipation.
The relative dielectric constant εr and the dissipation factor tgδ of the PZT thin films were measured with an LCR meter and were found to be 158 and 0.04-0.005, respectively.
The sap flow density, water consumption, and related environmental factors were also measured using thermal dissipation method and ICT-2000TE (Transpiration-Environment) automatic measuring system for tree transpiration and environmental factors.
