This article has been retracted at the request of the authors.Reason: Because of an inadvertent mix-up on their part, the article was submitted to, and accepted by, both Annals of Physics and Physical Review D simultaneously. This withdrawal does not in any way reflect on the scientific merit of the work. 相似文献

This article analyzes the influence of the radiofrequency mixing scheme on the sign of phase shifts experienced by the nuclear spins. It is an addendum to a previous article on the signs of phases and frequencies in NMR (M. H. Levitt, J. Magn. Reson. 126, 164 (1997)). 相似文献

Automatic methods of photoelasticity have had a significant progress with the development of automatic acquisition and image processing methods. This article concerns RGB photoelasticity, which allows the determination of the photoelastic retardation using, usually, a single acquisition of the isochromatic fringes in white light by a colour camera. In particular, the article presents an overview of the main characteristics of RGB photoelasticity that is influence of the quarter-wave plate error, number of acquisitions, type of light source, determination of low and high fringe orders, methods for searching the retardation, scanning procedures, calibration on a material different from that under test, combined use of the RGB and phase shifting methods. A short section on the applications of RGB photoelasticity completes the article. 相似文献

Abstract In this article, we compared the model results obtained by the naphthalene sublimation method with the results obtained by experiments with the real heat exchanger based on the model used in the naphthalene sublimation experiment. The results reveal that in the Reynolds number region studied in the present article, the experimental results obtained by naphthalene sublimation agree with the experimental data of the real heat exchanger under the working conditions within a 10% deviation. The heat/mass transfer coefficient obtained with an isothermal condition using naphthalene sublimation can be applied to the mixed thermal boundary condition. The effects of mounted and punched vortex generators on thermal-hydraulic performances are limited to the configuration studied in this article. 相似文献
