主位结构与口译中的信息处理

本文运用韩礼德的主位结构理论对连续口译中的信息处理作了初步探讨,文中用实例说明了主位结构与话语语篇的信息分布紧密相关,并对口译中的信息重组以及逻辑结构的把握起着重要作用。此外主位结构理论还对口译教学中笔记的分析与评估有着一定的指导意义。     

Weight measurement using image-based pose analysis

Image-based gait analysis as a means of biometric identification has attracted much research attention. Most of the existing methods focus on human identification, posture analysis and movement tracking. There have been few investigations on measuring the carried load based on the carrier＇s gait characteristics by automatic image processing. Nevertheless, this measurement is very useful in a number of applications, such as the study of the carried load on the postural development of children and adolescence. In this paper, we investigate how to automatically estimate the carried weight from a sequence of images. We present a method to extract human gait silhouette based on an observation that humans tend to minimize the energy during motion. We compute several angles of body leaning and determine the relationship of the carried weight, the leaning angles and the centroid location according to a human kinetic study. Our weight determination method has been verified successfully by experiments.

水稻花粉悬浮培养及其在育种上的应用

评估了２０个水稻品种离体花粉悬浮培养产生愈伤组织和再分化植株的能力，并进行了花粉悬浮培养试验，结果表明；品种之间反应差异很大。来源于日本的“黎明”（粳稻）最敏感。“黎明”植株再分化的频率达８４．１％。在愈伤组织的形成和植株再分化过程中，除其它一些因子外，基因型的差异有一定制约作用。通过水稻花粉悬浮培养诱导出的新品系“Ｎ１０”，其特征有：早熟，穗大，株高（９０～１００ｃｍ），产量高和抗稻瘟病等。
