新的文学社会空间之开拓——文协与抗战时期的战地文艺工作

通过全面梳理文协在抗战时期积极促进和推动战地文艺工作的基本史实,可以看出文协对战地文艺工作的理论倡导,主要表现在及时关注和报道战地文艺工作者行踪及其活动、大量刊载来自前线的文艺通讯、总结战地文艺工作经验等三个方面。而组织作家战地访问团和参加南北慰劳团,则集中体现了文协深入前线以推动战地文艺工作的实践活动。这些活动,既促进了战地文艺,又推动了文协自身的发展。     

地球空间双星探测计划国际合作管理实践及启示

 地球空间双星探测计划（简称“双星计划”）是中国首个空间科学卫星计划，也是首个以中国为主开展的深度国际合作的空间科学卫星计划，是中欧成功合作的典范。基于双星计划研制任务管理，透视了双星计划的国际合作情况，总结了双星计划国际合作管理实践。双星计划建立了严密的工程组织管理体系，通过工程月调度例会、专题协调会和大总体会，以及管理/技术协调会机制和联络机制，推动任务实施；通过科学指导委员会、科学工作队，以及科学工作联席会机制，促进成果产出最大化。其中，首席科学家机制、数据共享机制、文档编写规范、疫情应对举措等管理经验，为未来空间科学国际合作任务提供了重要借鉴。     

Seismic tomography of the Moon

We attempted to determine the first three-dimensional P and S wave velocity and Poisson＇s ratio structures of the lunar crust and mantle down to 1000 km depth under the near-side of the Moon by applying seismic tomography to the moonquake arrival-time data recorded by the Apollo seismic network operated during 1969 to 1977. Our results show that significant lateral heterogeneities may exist in the lunar interior. Because there is no plate tectonics in the Moon, the lateral heterogeneities may be produced at the early stage of the Moon formation and evolution, and they have been preserved till today. There seems to be a correlation between the distribution of deep moonquakes and lateral velocity variations in the lunar lower mantle, suggesting that the occurrence of deep moonquakes may be affected by the lunar structural heterogeneity in addition to the tidal stresses. Although this is an experimental work and the result is still preliminary, it indicates that tomographic imaging of the lunar interior is feasible.     

利玛窦肇庆传教的文化透析

肇庆是利玛窦中国传教的第一站.在这里,他采用“基督教中国化“的传教方略,从观念与具体方式上主动趋合中国文化,获得本土人士在心理与感情上的沟通和认同,使其取得了传教的初步成功.在他的传教活动中,充分展示出外来文化与本土文化在交流中的互动、趋同等重要现象与规律,有着文化传播学上的意义.对这些文化事象与文化意义,应该给以充分的关注.     

新形势下高校教师的责任、使命与角色定位

当今世界,经济全球化趋势加快,知识经济和高新技术不断发展,高校的功能也随着社会的进步而不断地拓展和丰富起来。这既是社会发展对高校提出的要求,也是高校在不断适应社会需要过程中对自身功能的调整和充实。作为具有社会良知的知识分子和社会发展主导力量之一的高校教师,应在国家、社会及其公众当中担当起道德标杆、社会导师、知识引领、行为示范和意见领袖的作用,扮演好言传身教的育人者、授人以识的传导者、纳人以虚的亲和者、率人以先的创新者、终身学习的践行者、＂文化自觉＂的传播者、人格独立的评判者的重要角色。     

A cyanoglucoside stored by aSedum-feeding Apollo butterfly,Parnassius phoebus

A bitter tasting cyanoglucoside, sarmentosin, was isolated from an aposematic Apollo butterfly,Parnassius phoebus, and from its plant-host,Sedum stenopetalum. The content of sarmentosin in the body tissues was as high as 500 g/insect, suggesting a defensive role for this substance; a high concentration was detected in the wings. Sarmentosin was also present in the eggs.     

亚丁湾护航背景下译员的能力构成及相关问题探讨

为填补亚丁湾护航背景下译员能力及相关问题研究的空白,根据参加海军亚丁湾索马里海域护航编队翻译工作的实践,以翻译能力的界定为先导,从政治素养、英语能力、外事能力、参谋能力、航海知识和了解外军兵力六个方面论述了护航译员的能力构成.通过分析护航译员的业务能力、管理机制、批次问衔接传承、角色定位等因素,指出了护航译员的能力构成存在的相关问题,并针对性地提出了相应的解决途径.     

面向航天测发任务的动作识别与追踪研究

航天测发任务精度要求高、任务周期长,且长期暴露在阳光直射下。为提高测发任务的成功率,在虚拟工作环境中进行无接触式动作标定与矫正是一种高效的方式。针对航天工作人员动作的实时动作追踪问题,提出了一种关键帧优化的动作识别算法。依据深度图像中的骨骼数据,提取骨骼特征,使用特征阈值提取关键帧。将关键帧的特征数据输入双向长短期记忆网络,优化整体动作识别的精确度。数据驱动的骨骼识别与动作追踪,能有效识别航天工作人员的动作,辅助其更高效、安全地完成测发任务。     

中西文学之"乌托邦"现象概论

作为各自文化载体的“乌托邦”现象,在中西文学中可谓源远流长,且存在丰富的可比性。本文尝试用新的文学理论来阐释其内涵、品格并比较中西“乌托邦“现象的类型和流变,最终旨归于“乌托邦”的宏观审视。     

New moon from an old hand

The outcome of the Apollo lunar exploration program 1969-1974 was a model of lunar petrogenesis which ignored the probability of selective volatilisation of gases and alkalis from fire-fountaining lunar basalts. It overlooked the fact that the average compositions of the erupted basalts were those of plagioclase-saturated and low-pressure cotectic liquids on eruption, clearly indicating that they were not primary magmas. The basalts may have undergone evolution by gabbro fractionation within the lunar crust, perhaps in large lava lakes now solidified as the lunar maria. The existing model involving a global magma ocean and plagioclase flotation to form the lunar crust arises solely from the incorrect assumption that the basalts are primary magmas. The plagioclase flotation hypothesis requires the presence of a significant positive europium anomaly in the lunar highland crust, and was founded upon its alleged presence. However, that positive anomaly is neither established by the original data set nor by the much broader current data set. Critical observations, and experiments which will advance the debate are suggested, and alternative interpretations outlined.
