For Ba-doped 2223 phase, the study of electron diffraction indicated that Ba ions got into the 2223 phase and caused the change of crysral micro-structure of 2223 phase, a new additional superstructure appeared along b axis, and two kinds of modulation mode were observed simultaneously along this direction, the wavelength of which is 27A, 43A respectively.
Value of b came down from 1.3 to 0.55. Consulting sudden change of radon content inground water we culculated magnitude of future principal earthquake would be bigger than 6.5. We consulted the general modulation model of the reference  and detemined place where is earthquake focus was modulated, thus made the impending earthquake prediction of the Laizhou earthquake (M=7,0).
On the premise of studying the physics basis produced by unstability of source system,andaccording to the modulation model,we put forward the suggestion to make short term predic-tion using correlation between external agencies and frequency fluctuation intensification ofsmall modulation earthquakes,we also suggest two indexes λ_1,λ_2 to discriminate the unstabilityof source system,the former is the unique factor modulation index,and the latter is multi-factormodulation index , or multi-factor modulation intensification index.
It also gives the design of the hardware and the flow chart of the software control. This mode have many advantages,such as multiplicity modulation modes,high precision,wide band of frequency and modulation bandwidth.
Atomic force microscopy (AFM) in force modulation mode was adopted to study the cross-section surface of unidirectional CF/PAA composites and the relative stiffness of various phases, including CF, interphase and resin.
Experimental and theoretical studies on the self-modulation mode of generation in a high-power BWT with the electrodynamic system representing a slightly corrugated waveguide are presented.
Experimental observations are in good agreement with the results of simulation predicting a certain simplification of the self-modulation mode at the currents 70-90 A owing to the effect of high-frequency space charge.
SFM in force modulation mode has visualized different interphase thicknesses and gradients of local stiffness.
Furthermore, the biphasic modulation mode is probably due to diverse nucleotide-Fe(II) complexes formed in a concentration-dependent manner.
We found that the simple self-phase modulation model cannot explain this high coherence between the white continuum sources.
It is concluded that the low-pass filtering of R-R interval data will yield fair estimates of the controlling neural signal and that the pulse frequency-modulation model is applicable to this and other physiological systems.
Spectrum of a series of point events, generated by the integral pulse frequency modulation model
Spectral analysis of heart rate variability using the integral pulse frequency modulation model
Based on a modulation model of nonlinear parametric instability, some theoretical expectation of statistical relation of solar radio spikes have been obtained.
To classify the frequency modulation signal, this paper employs a parameter invariant filter, which can transfer the frequency modulated information to variety of its envelope, and then extracts the histogram feature to classify the modulation type.
