＜正＞Fuzzy dominance is a relatively new concept for ranking fuzzy variables based on their credibility distributions. The second order fuzzy dominance is introduced against the backgrounds of studying economic behavior in finance and insurance under uncertainty in a fuzzy environment. In this paper, we made some remarks on the basic properties of the second order fuzzy dominance. As an illustration, the case of the second order fuzzy dominance for trapezoidal fuzzy variables is investigated.

为了探讨参加温哥华冬奥会的韩国短道速滑女队实力,采用文献资料、录像观察等方法对新一届韩国女队组队情况、训练特点、近3年ISU主办的世界重大比赛韩国女队成绩进行了分析。结果表明:韩国国家队选拔赛组织非常严密,竞争激烈,体现了公平、公正的比赛宗旨;新一届女队员传承了韩国队员的特点,多名队员在中长距离项目上具有很强实力,而短距离项目上实力相对弱一些;韩国队员训练负荷大、针对性强,韩国队仍然是中国女队在温哥华冬奥会上夺金的重要障碍。建议:利用韩国队从7月份开始海外训练的时机,作好对韩国队的信息研究,采取针对性的对策。

Analytical models of acoustic field excited by a pulsed-laser line source on a cylinder and a coated cylinder were presented. Surface wave dispersive behaviors for a cylinder with a slow coating were analyzed and compared with that of a bare cylinder. Based on this analysis, the laser-generated transient response of the cylindrical Rayleigh wave on cylinder and the perturbed cylindrical Rayleigh wave on coated cylinder and the higher modes were calculated from the models using residue theory and FFT technique. The theoretical results from the superposed waveform of the cylindrical Rayleigh wave and higher modes for both cylinder and coated cylinder agree well with the waveforms obtained from experiment. The transient response of perturbed Raleigh wave on coated cylinder is quite different with cylindrical Rayleigh wave on cylinder because of the guide of surface coating. The results show that the model and numerical method provide a useful technique for quantitatively characterizing coating parameters of coated cylinder by the laser generated surface waves.
