The Frontier Movement and The American Values and Beliefs

This paper briefly accounts the background of American values and beliefs. It analyses the essence of the American ideals and points out that the American values are exaggerated and glamorized by the American upper class. They are in a sense, a dose of anaesthetic and a kind of hypocrisy.     

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.

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.     

某库岸滑坡稳定分析及治理措施研究

从地质条件出发,详细分析了滑坡的成因,以大型的岩土工程数值分析软件(ADINA)为研究手段,建立有限元计算模型,用强度折减的方法分析了滑坡体在初始工况、蓄水工况、暴雨工况、水位骤降工况和地震工况下的稳定情况,根据滑坡的失稳情况,在综合考虑的基础上,提出了削坡减载和地表排水相结合的治理措施,计算结果表明,治理措施是可行的,研究结果对设计和施工具有较大的参考价值.

家庭的消费行为规律

家庭是社会消费的基本单位,大多数商品都是直接供家庭购买与消费的。即使是家庭个体成员的消费,也会受到家庭各方面因素的直接或间接的影响。家庭特征与家庭消费行为规律之间存在一定联系,尤其是家庭经济收入、家庭类型、家庭生命周期、家庭消费角色对家庭消费行为有很大的影响作用。探讨家庭的消费行为规律,对工商企业制定合理的营销策略有重要的意义。
