Result:MAC of isoflurane,the relative power(RP)of δ wave and the latencies of BAEP and VEP were decreased when spinal cord was preferentinally anesthetized (P<0.05),but RP of β and α wave and spectral edge freqency (SEF)were increased (P<0.05 or P<0.01),and simultaneously all goats demonstrated the signs of awakening and had strong response to the noxious stimulation of ear.
When patients slept, the spectral edge frequency (SEF) decreased immediately to the lowest value(P<001), the total power of EEG increased by times (P<001), and the δ relative power was dominant. The decreases of SEF returned to the level of preinjection within 1 min.
There is a contradiction between resolution and wavelength coverage in normal OMA. We can enhance the resolution from over 0.12 nm to under 0.01 nra by using a optical accessory and a program designed by us with 2-dimension OMA.
Abstract Using the combination of the quantum Monte Carlo and the maximum entropy methods,we studied the optical conductivity of the two-dimensional Hubbard model. At half filling, arenergy gap is observed in the spectra. Up on doping, a Drude peak appears at the end of thlOw freqency region, a new peak is presented in the gap region, and' the spectra Weight i!
Raman spectra of nanocrystalline Nd 2O 3 were measured. It is found that the Raman peaks shift red and broaden asymmetrically with the decrease of particle sizes. This phenomenon was elucidated by the quantum size effect.
The WIYN 3.5-meter telescope and its Multi-Object Spectrograph (MOS) have been used to obtain simultaneous spectra at many points in the coma of Comet Hale-Bopp.
We obtained simultaneous spectra with a spatial resolution of 1/2″ and a temporal resolution of 15 s in Hα, Ca ii-K, Caii 8542 ?, and three Fei lines of the sunspot group responsible for the large flares of August, 1972 (McMath No.
Simultaneous spectra in K and λ 8542 show unambiguously that the evolutionary behaviour of the K-line profile due to an outwardly propagating velocity pulse.
The spectral width of Bragg reflections is studied, and it is shown that the reflection width depends not only on the quasicrystal dimensions in the physical space but, also, on the perpendicular component of the reciprocal-lattice vectors.
The dependence of the rms spectral width of a light pulse consisting of several light-field oscillations on the distance passed in an optical waveguide with arbitrary dispersion and nonresonant electronic nonlinearity has been derived.
The present work is to cxtend I. S. Frishman's method① of spectral analysis by means of calculated working crve to spectral work with arcs. Investigations have been made to analyze tungsten in steel (analysis lines chosen: w 4008.76 and W 2397.11) with various are current, slit width and electrode spacing.Our results showed that Frishman's method can be extended to the case of are sources, except that the range of concentration of analysis is narrower than the case of spark sources. It is also found that th...
For the target flying in the spacw, if it not only moves along a certain orbit but self-rotates, the additional phase-modulation will appear in the signal replied by the coherent transponder because the phase distribution of the signal radiated by the transponder antenna system is not uniform. In the result, an additional error in the Doppler measurement will be brought about. In this paper, an additional Doppler frequency in such signal is analysed, that signal is replied by the coherent transponder carrie...
