In physics, angular wave numbers are generally used rather than linear wave numbers. This means the wave number is measured in radians per unit time, not wave cycles. As a result, the wave number formula must be modified to take into account the differences in measurement and their relationshi...
This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years ...
The limitation of the number of sensors makes it impossible to use the first method in the measurements of the high-order derivatives. The technique of processing in the wavenumber domain, based on the spatial Fourier transform of 2D-vibrating fields has not such a limitation. It has been ...
We present experimental results for patterns of Rayleigh-Bénard convection in a cylindrical container with static sidewall forcing. The fluid used was methanol, with a Prandlt number sigma=7.17 , and the aspect ratio was Gamma identical withR/d approximately 19 ( R is the radius and d the ...
Turbulence commonly described in Fourier space due to its multi-scale nature can be formulated using wave-number space networks where each node represents a wave-vector on a discretized wave-number space grid that are connected to one another through triadic interactions denoted as three-body connect...
可数名词 Waves are the form in which things such as sound, light, and radio signals travel. (光、声、无线电等的) 波 Regular repeating actions such as sound waves, light waves, or radio waves have a certain frequency, or number of waves per second. 有规律的重复活动如声波、光波、无线电波...
The possibility to characterize these transitions by the first weighted moments of their wave-number distributions is clearly demonstrated. {copyright} {ital 1996 The American Physical Society.} 展开 关键词: physics iron transition radiation l shell infrared spectra quantum numbers spectroscopy line ...
r-Process nucleosynthesis stands for ‘rapid neutron capture nuclear process’, whereby a nucleus rapidly increases its atomic number by repeatedly capturing neutrons in a neutron-rich environment. Standard siren A gravitational-wave source that is determining the absolute distance to the source. Extreme...
Soundwaves, lightwaves, and radiowaveshave a certain frequency, or number ofwavesper second. 声波、光波或无线电波等都有特定的频率,或者说是每秒的波数。 柯林斯高阶英语词典 She felt awaveof panic, but forced herself to leave the room calmly... ...
We review the theoretical machinery of quantum wave packet construction leading to the existence of revivals and fractional revivals, in systems with one (or more) quantum number(s), as well as discussing how information on the classical period and revival time is encoded in the energy eigen...
