对读者身份的文化误读与理论译著的不可读性——译著《当代文学理论导读》的文化评析

通过对《当代文学理论导读》的英汉对比分析,揭示译者对读者身份的文化误读与理论译著文本的不可读性之间的相关性。理论著作重在传达原作的思想内容,宜采取交际(而非语义)的翻译策略,可增强译作的可读性;如果没有准确预设读者的文化身份,采用语义翻译方法,则容易造成译作的晦涩难懂,不利于普通读者接受。     

文化遗产旅游解说与翻译:评述与启示

文化独特性是文化遗产型景区的核心吸引力,了解和欣赏异质文化遗产是文化旅游者的主要动机,解说翻译是跨文化遗产旅游的桥梁。由于国内旅游规划对文化遗产旅游解说特点研究不够,景区管理者对双语解说信息创作对象不了解,导致文化遗产解说与翻译的质量影响了跨文化遗产旅游的解说教育效果,错过了通过文化遗产旅游平台对外宣传中华文化的良好机会。综述了旅游解说的概念、内涵以及有效解说和信息创作的原则,在总结文化遗产旅游特点的基础上,提出了文化遗产型景区英文解说翻译应针对国际旅游者特点的信息再创造的观点。建议文化遗产旅游景区制定针对国际旅游者消费特点的双语解说规划;旅游规划和翻译学术界应重视旅游双语解说规划和翻译的研究;翻译者在具备双语、双文化翻译能力的同时,还应该了解旅游解说和信息创作的跨学科知识。     

Variability in bedform morphology and kinematics with transport stage

Bedform geometry is widely recognized to be a function of transport stage. Bedform aspect ratio (height/length) increases with transport stage, reaches a maximum, then decreases as bedforms washout to a plane bed. Bedform migration rates are also linked to bedform geometry, in so far as smaller bedforms in coarser sediment tend to migrate faster than larger bedforms in finer sediment. However, how bedform morphology (height, length and shape) and kinematics (translation and deformation) change with transport stage and suspension have not been examined. A series of experiments is presented where initial flow depth and grain size were held constant and the transport stage was varied to produce bedload dominated, mixed‐load dominated and suspended‐load dominated conditions. The results show that the commonly observed pattern in bedform aspect ratio occurs because bedform height increases then decreases with transport stage, against a continuously increasing bedform length. Bedform size variability increased with transport stage, leading to less uniform bedform fields at higher transport stage. Total translation‐related and deformation‐related sediment fluxes all increased with transport stage. However, the relative contribution to the total flux changed. At the bedload dominated stage, translation‐related and deformation‐related flux contributed equally to the total flux. As the transport stage increased, the fraction of the total load contributed by translation increased and the fraction contributed by deformation declined because the bedforms got bigger and moved faster. At the suspended‐load dominated transport stage, the deformation flux increased and the translation flux decreased as a fraction of the total load, approaching one and zero, respectively, as bedforms washed out to a plane bed.     

结合投影变换和相位相关的海冰运动监测

为提高对渤海海冰旋转和平移运动的监测精度,提出一种基于投影变换的相位相关跟踪方法。选取连续8景静止水色成像仪(GOCI)图像序列,根据特征图像窗口的投影变换构造辅助函数,通过寻求函数最优解得到旋转角度集合,选择修正相关系数确定最佳旋转角度,同时根据相位信息实现海冰样本间亚像素级别的平移跟踪,消除传统相位相关法中因忽略图像相频特性所造成的匹配误差。实验结果表明,以手动测量的旋转角度为基准,该方法和传统相位相关法的旋转监测均方根误差的最大值/平均值分别为0.59/0.50与1.41/0.94,跟踪速度提高了50.6%;海冰平移运动的速度矢量与辽东湾的现场实测数据及历史资料记录数据基本一致。该方法对渤海海冰旋转和平移运动具有较好的跟踪效果。

基于移不变全方向角提升的遥感图像降噪

在分析遥感图像结构特征及其与噪声之间主要区别的基础上,利用图像信号的方向信息,提出基于移不变全方向角提升小波（TI—OL）抑制遥感图像噪声的方法。该方法在方向提升小波变换的基础上并利用循环平移,Gabor小波滤波器和图像旋转技术改进了方向提升小波在图像去噪过程中存在的三个弊端：缺乏移不变性质,图像局部方向信息判方法断缺乏噪声鲁棒性和变换方向分布有限。消除去噪结果中的吉布斯效应,提高图像方向信息判断的准确性并保证图像纹理方向始终落在方向提升能最优表示的方向区间内。试验结果证明所提方法在处理遥感图像的过程中能在去噪的同时保留图像的细节和边缘信息,对遥感图像中的边缘信息如道路和桥梁有较好的刻画性能,较传统方法去噪性能（PSNR）和主观视觉效果（SSIM）均有较大提高。

基于EMD方法的地心运动时间序列分析

针对时间序列混有的高频信息会影响地心运动规律分析的问题,采用网平移法对IGS提供的GNSS周解进行解算,得到2007-2017年地心运动时间序列,对其进行分解重构,剔除高频项,并利用重构时序对地心运动规律作进一步分析探讨。结果表明：本文解算的地心运动在T_x、T_y和T_z方向的精度均为毫米级。EMD方法重构的时序保留了原序列的基本信息,且抑制了高频项的影响,提高了周期贡献率,3个方向的贡献率分别提高了12.3%、16.7%及6.3%。通过分析重构后的时序发现,周年项振幅为各周期对应振幅的最大值,分别为2.32、1.89和2.07 mm;T_y和T_z方向长期变化趋势较T_x更为明显,分别为0.13和-0.27 mm/a;半年项较小,且在T_x和T_y方向上具有时变性。此外,还发现了一些其他较小的年际变化。     

History of faulting in the Northern Hastings Block,southern New England Orogen

Brittle failure is common in the Devonian to Permian rocks in the Northern Hastings Block (NHB) and is manifested by faults of different orientation and kinematic histories, but the timing of fault movement is not well defined. In this study, faults in the NHB were analysed with the map pattern of cross-cutting faults used to estimate the relative time of movement and relationship to other faults. We defined five episodes of faulting or fault reactivation that affected the NHB. The Yarras Fault System on the southwestern side of the NHB and the Parrabel Fault and related faults on the eastern side of the NHB are the two major fault systems responsible for transporting and rotating the NHB in the late Carboniferous. Faults on the eastern, northeastern and northern part of Parrabel Dome started and stopped moving after emplacement of the Hastings Block and before the intrusion of the Werrikimbe Triassic granitoids. We suggested that the movement on the major bounding faults is related to the accommodation of the NHB to the folding and cleavage development in the adjoining Nambucca Block, and is associated with the earliest part of the Hunter–Bowen Orogeny. Limited dextral movement on the extensions of the Taylors Arm Fault System caused minor displacements in the northeastern part of the NHB during the Late Triassic. Some small faults cut the Triassic granitoids or Triassic Lorne Basin sediments indicating tectonic activity continued post-Triassic.
