John Y. Mak, in Handbook of Natural Gas Transmission and Processing (Third Edition), 2015 2.2.4 Phase velocity Phase velocity (in situ velocity) is the velocity of a phase of a multiphase flow based on the area of the pipe occupied by that phase. It may also be defined for each phase...
The increase in the inductance and the capacitance per unit length between the transmission line and the grounding plate is advantageously employed to provide a reduced phase velocity for electromagnetic signal transmitted through the transmission line. A design structure for the transmission line ...

An improved formula for continuous‐wave ultrasonic phase velocity measurements using contact transducers is derived from the transmission line theory. The... Chern,Engmin J - 《Journal of Applied Physics》 被引量: 21发表: 1981年 Laser-ultrasonic monitoring of ferrite recovery in ultra low carbon ...
A vehicle (F) travelling along parallel to the line (L) has an onboard receiver which picks up signals from both transmitted signals but shifted in phase and frequency in both cases by the Doppler shift produced by the vehicle velocity.GAUTSCHI,MAX,DR....
In spite of the extensive studies of zero-index metamaterials, the realization of zero impedance with finite phase velocity has not been explored. Here, we show that this extreme case, realized by elaborately-tuned paired resonators, can effectively enha
aIn line with the above quotation from Cavaco many studies highlight the positive effects of tourism activities in revitalizing rural areas, both in economic and environmental terms. 根据上述引文从Cavaco许多研究在使乡区复苏突出旅游业活动的正面作用,用经济和环境术语。[translate] ...
Discovery of Relativistic Outflow in the Seyfert Galaxy Ark 564 We present \\chandra high energy transmission grating spectra of thenarrow-line Seyfert-1 galaxy Ark 564. The spectrum shows numerous absorptionlines which... A Gupta,S Mathur,Y Krongold,... - 《Astrophysical Journal》 被引量: ...
The analyzed phase-shifter realization with memristor is based on the loaded line presented in Fig. 4.4a. The main transmission line is loaded by two identical variable susceptances, which distance is approximately a quarter wavelength at the center frequency. This realization is used for phase-shi...
The contrast in high-angle-annular dark-field (HAADF) scanning transmission microscopy (STEM) image reflects density difference, where regions with higher density (Zr-Ti-Nb-Hf-Ni-Co) reveal brighter (Fig. 1b). The Cr-Ni-Co phase has a crystalline structure, composed of face-centered-cubic ...
