常规叠后地震道反演技术 ,受多种因素的影响。在实用中 ,很难获得准确的结果。从地震道反演的主要技术环节来看 ,造成地震道反演错误或解释陷井的原因主要集中在噪声、假设条件、子波提取、时深转换、低频分量、约束条件等方面。PatrickConnolly提出的弹性阻抗 (elasticimpedance)的思想 ,改进了反射系数垂直入射假设的错误 ,巧妙地将AVO问题与地震道反演相结合 ,将地震道反演技术向前推进了一步。在此基础上建立的适合常规叠后资料的、非零炮检距纵波资料的广义弹性阻抗 (generalizedelasticimpedance)模型不仅包含波阻抗 ,还包含了纵横波速度等岩性信息。进一步发展纵波与转换波弹性阻抗的联合反演 ,能更准确地获得纵横波速度信息 ,还能获得流体饱和度及渗透特性的信息。

多载波CDMA系统结合了正交频分复用(OFDM)技术和CDMA技术的优点,自1.93年提出以来就受到了广泛的重视。本文主要讨论载波频偏对连续OFDM符号的影响,提出了一种新的频域线性相位内插算法来估计信道响应,以对抗载波频偏对连续OFDM符号引起的相位旋转。理论分析和仿真试验都证明我们提出的算法能有效减少载波频偏对系统性能的影响。这种新算法适用于使用导频信号块状分布的多载波CDMA系统或OFDM系统。

As an economically critical pelagic migratory species,yellowfin tuna(Thunnus albacores,YFT)is very sensible to physical and environmental conditions,such as sea surface temperature(SST),ocean heat content(OHC),and the mixed layer depth(MLD).We investigated the impact of SST,OHC,and MLD on fluctuations of YFT catch in the western/eastern Indian Ocean using the long time series of 63-year environmental and YFT *** found that the impact of SST on YFT was heavily overestimated in the past,and MLD plays a more critical role in the YFT catch *** the MLD deepens(>34.8 m),SST was more influential in predicting the catches of YFT than OHC in the western Indian Ocean,and OHC was more critical to YFT than SST in the eastern Indian ***,when the MLD shallows(<34.8 m),MLD was more vital to predict the catch per unit effort(CPUE)of YFT than SST/OHC in the *** 2000,there was an asynchronous pattern of YFT CPUE induced by higher frequency variations and ocean hiatus of SST/OHC signals in the western and eastern Indian Oceans *** impact of the subsurface hiatus may induce the decrease of YFT in the eastern Indian *** above findings clarified a non-stationary relationship between the environmental factors and catches of YFT and provided new insights into variations in YFT abundance.
