The Response of Debris-Flow Events to Solar Proton Flares （Ⅰ）

By analyzing the observation data from Dongchuan Debris Flow Observation and Research Station and historical data from year 1965 to 1990 gotten from National Astronomical Ob-servatories/Yunnan Observatory,the responding of debris flow in Jiangjia Ravine to Solar Proton Flare is studied. The following conclusion can be drawn. Solar Proton Flare,as one of most im-portant astronomical factors,affects the activity of debris flow in Yunnan. Generally,from 1965 to1990,the more active Solar Pro-ton Flare is,the greater the probability of high frequency and large runoff of debris flow is. On the contrary,the less active Solar Pro-ton Flare is,the greater the probability of low frequency,small runoff,and low sediment transport of debris flow is.     

冲击压实技术在西湟一级公路黄土处理中的应用

Picturing the moon: Hevelius’s and Riccioli’s visual debate

This article investigates the maps of the moon produced in the mid-seventeenth century by Jesuit Giambattista Riccioli (1598-1671) and Johannes Hevelius (1611-1687), whose cartographic projects competed for widespread acceptance. Although Hevelius’s Selenographia (1647) was applauded for its many detailed, self-engraved pictures of the moon, his cartography and proposed nomenclature were supplanted by Riccioli’s as offered in Almagestum novum (1651), in spite of the latter’s simplistic pictures and promotion of geocentric cosmology. Exploring this paradox through pictorial analysis, three types of images common to both Selenographia and Almagestum novum are compared, employing an analytical tool developed by Svetlana Alpers in The art of describing (1983). A focus on this debate exposes the tensions evoked by new technologies of vision and competing cultures of visual epistemology in seventeenth-century astronomy. As both selenographers grappled with questions about the role of representation and what kinds of knowledge could be generated visually, the successes and failures of their competing projects present implications for the course of visual astronomy, as well as for our understanding of the use of ‘visual technologies’ in a period of controversy.     

旋流场中分散相颗粒径向受力及径向速度方程

从两相流的角度阐释了分散相单颗粒在旋流场中的径向受力，并对各力进行了分析和简化．运用力分析的方法建立了颗粒径向速度对于径向位置分布的径向运动方程，探讨了颗粒径向速度的求解．结果表明，经典的平衡轨道理论所认为的沉降速度只能在某一特定位置出现，并不具有实际应用意义；而径向运动方程则可以求解，并可作为旋流场进一步讨论的基础．

籽瓜植株(地上部)的生长发育规律

对内蒙古地区有代表性的四个籽瓜品种植株(地上部)的生长发育进行了研究．结果表明：内蒙古籽瓜的全生育期为92-101d，籽瓜植株的生长发育可分为发芽期、幼苗期、伸蔓期和结果期，结果期分为前期(开花座果期)、中期(果实膨大期)、后期(种子成熟期)．发芽期、幼苗期以叶为生长中心，伸蔓期、结果前期以茎为生长中心，进入结果中期以果实为生长中心不同生育分期长短的差异主要表现在结果中期的差异上．
