The absorption range of diffuse reflectance infrared spectroscopy of natural jadeite are 400cm-1-1200cm-1. the absorption bands at 1190cm-1, 1130cm-1, 965cm-1, 595cm-1, 525cm-1 are the characteristic absorption peak of diffuse reflectance infrared spectroscopy of natural jadeite.
Within IR region of 400～1600cm -1 ,400～600cm -1 absorption band is the characteristic absorption of MgF\-2 crystal whereas 730～1250cm -1 absorption band is caused by Ag\|MgF\-2 cermet with compound structure.
Results:There were specific absorption peaks in the chromatogram, and linearity was found at the range of 0.52 ～ 8.32 μg of Ginsenoside Rg 1( r =1.000 0), the average recovery was 96.8%, and RSD =1.48%.
The conformation of B-phycoerythrin changed remarkably with 0.5%-3% SDS or 0.25%-1% β-mercaptoethanol,the fluorescence emission intensity declined greatly,and the specific absorption peaks disappeared.
The specific absorption bands appeared in differential spectra, indicating that direct bonding probably exists between the extracted metal ion and the oxygen donor in the ring of these crown ethers, and the nitrate group acts as a dentate in these extracted complexes.
The results indicate that sulfated inulin is synthesized successfully by three methods: CA-Py in Py,SO_3-Py in Py,and CA-Py in DMF. The special absorption of IR at 1255 cm~-1(C=S) and 810 cm~-1(C-O-S) confirmed the structure of the sulfated inulin takes place.
The TEM study showed that gels fram hydrolysis of VO(OC_2H_5)_3 possessed a fibrous texture and FTIR absorption spectra showed special absorption peaks of V_2O_5. DTA and XRD analysis indicated the crystallization of amorphous V_2O_5 occured in gels at 340℃.
Based on the characteristics absorption of Infra-red spectra and the Intensity differences of absorption for OH groups in high frequency range, qualitative and quantitative analysis for clay minerals of kaollnites were made.
Nd~(3+)∶SGG crystal with a dimension of 26mm×15mm was obtained, and its optical absorption spectrum was measured. The characteristics absorption peak is located at 806nm and it broadens and shifts to short wave compared with that of Nd~(3+):YAG crystal.
We analyzed the appearance/disappearance of characteristic absorption bands of A and B DNA forms and determined D1088/D1224, the ratio between the band intensities of symmetrical and asymmetrical oscillations in their phosphate groups.
The absence of the main characteristic absorption band of the NpO2+ dioxocation (980 nm) in the electronic absorption spectrum suggests centrosymmetrical equatorial surrounding of the Np(V) atom.
The results show three characteristic absorption bands around 1440, 1900, and 2500 nm.
It is shown that the change in the profile of the characteristic absorption band and the position of its peak correlate with the characteristics of formation of the ripples on the silicon surface.
The IR spectra indicate the presence of a silicon carbide phase, identified as the cubic β-SiC, with a characteristic absorption at 800-833 cm-1.
Specific absorption cross sections of cylindrical and spherical particles are compared.
The specific absorption cross sections for spherical and cylindrical particles are compared.
Before then the specific absorption rate (SAR) distribution for the transvaginal probe have been measured in a phantom.
The local Specific Absorption Rates (SARs), the whole-body average SARs and the layer average SARs for the inhomogeneous block model of human body with different incident direction and different polarization of the incident waves are calculated.
Cell samples were exposed to 864 MHz continuous wave at an average specific absorption rate (SAR) of 0.08 W/kg.
