- 《Journal of Nuclear Science & Technology》 被引量: 12发表: 1967年 The spectrum of energy-rich protons from the reaction O16 (γ,p)N15 Oxygen gas was irradiated with 34.5 Mev bremsstrahlung. The spectrum of protons between 6 and 22 Mev was measured with a NaI(Tl) scintillation ...
Fuel cells are an important technology for converting hydrogen to power and heat through the electrochemical reaction of hydrogen with oxygen [51]. Carbon capture storage (CCS) [52] is another advanced technology that will be proposed to reduce GHG emissions. In this study, only CCS applied in...
aEmission spectrum of TPE-PyT-CPS in acetonitrile/water mixtures with varied water fractions (ƒw).bEmission intensity plot ofI/I0(dark dot) and the maximum emission wavelength (red dot) of TPE-PyT-CPS in differentƒwof the solvent mixture,I0represents the emission intensity in acetonitrile...
In TA, patterns of shared meaning, so called themes, are generated by the researchers to show how different data points relate to a central concept or idea. The themes are used to structure the coded data and tell a story. The tool have been used in a wide spectrum of theoretical ...
The damping may be independent spontaneous emission or collective spontaneous emission depending on the spatial arrangement of the atoms. We present the probe spectrum and photon statistics of the emitted light as a function of the number of atoms, the strength of the long range interaction, the ...
Evolution of hydrogen and oxygen from electrodes in an electrolysis cell may be conveniently monitored in a non-intrusive manner via its ultrasonic acoustic emission. The apparatus used in this work was comprised of a nickel anode, a stainless steel cathode, and a saturated calomel reference ...
Since in the present paper, the transition between states in a continuum spectrum are discussed, then to obtain the rate, we must integrate after the final momenta in Equation (31). Then, the rate definition for the process of Z emission by a neutrino is R ν → Z ν = 1 ( 2 π...
A total of four different sets of optics, each with its own spectrometer, perform the imaging at the same axial location. The spectrometers are selected as a function of the region of interest of the electromagnetic spectrum, which itself depends on the shock wave velocity, test gas pressure,...
One of the main preventive measures recognized by WHO and implemented to mitigate the COVID-19 epidemic impact, by controlling the transmission of coronavirus, was the use of a facemask. Since a facemask is an accessory that can be used several hours a day, through which the air we breathe...
They proposed signal feature extraction methods of the wavelet characteristic energy spectrum coefficient and the characteristic vector. These methods can study the change of rock mass stress in the process of water inrush. It lays an important foundation for analyzing the evolution process of water ...
