Erosion and Sediment Production in Small Watershed in Purple Hilly Areas and Prevention Techniques

Purple Soil distributes extensively and mainly in China. Because of abundant easily weatherable parent rocks/materials and unstable soil structure, and also influenced by parent materials, usage systems, and slope gradients, erosion and sediment production of purple soils are very severe with main fashions of water erosion and gravitational erosion. Basing on observed data in small watersheds, rainfall erosivity,vegetation coverage, previous soil water content, flow and relating factors such as climate, topograph of small watershed,land usage, and soil kinds are all the influence factors of erosion and erodibility of purple soil as well as sediment production and transport in small watershed of purple hilly areas.The effective technological countermeasures of ecosystem restoration, agricultural tillage for water conservation and erosion prevention, agriculture project, and soil changing for fertility and anti-erosion were provided.     

A new model for the life prediction of GH4133 under TMF conditions

Thermal mechanical cyclic strain tests were carried out under in-phase and out-of-phase conditions on a Nickel-base Superalloy GH4133 in the temperature range of 571-823℃. Based on analyzing the present models of TMF (thermal mechanical fatigue) life prediction, a new model for predicting nickel-base superalloy TMF lifetime was proposed.TMF life of superalloy GH4133 was calculated accurately based on the new model. Experimental TMF life has been compared with the calculatedresults and all results fall in the scatter band of 1.5. The calculating results show that the new model is not only simple, but also precise. This model will play great roles in life prediction of the metal materials and the engineering components subjected to non-isothermal service conditions.     

A Dynamic Forecasting System with Applications in Production Logistics

Production logistics involve the co-ordination of ac tivities such as production and materials control (PMC), inventory management, p roduct life cycle management, etc. Those activities demand for an accurate forec asting model. However, the conventional methods of making sell and buy decision based on human forecast or conventional moving average and exponential smoothing methods is no longer be sufficient to meet the future need. Furthermore, the un derlying statistics of the market information change ...     

文化生产场域中符号权力的形成--以文学艺术场域的分析为例

文化生产场域的生成不仅为文化生产者提供了游戏的空间,同时也区分了文化资本的富有者和贫乏者,文化资本数量上的落差导致了符号权力关系的建立;对文化资本功效和意义的认可赋予了它足够的价值,在价值认可的基础上,文化生产者的符号权力得以合法化;而文化资本的符号特性往往会造成文化生产者本身的符号化,关于作者的各种神话被创造出来,他们的符号权力因而得到进一步强化。

三维动画课件在案例教学中的应用

《生产与运作管理》案例教学的案例一般均为实际问题,涉及的因素广泛、复杂.受单纯文字表达或平面图形静态表达的限制,加之缺乏实践经验,使学生对案情的理解往往产生较大的偏差,以至于难以充分发挥案例的作用.本文对采用三维动画课件的形式,立体、动态地表达案情,建立更为接近实际情况的动态模型,开展案例教学进行了探讨.结论是三维动画课件特别适合于运作管理案例教学,有利于显著提高MBA学员的教学参与程度,提高案例分析和方案设计的水平.     

论欧阳修碑志文的创作

欧阳修碑志文重视立言“不朽而存”的价值 ,坚持“事信言文”的创作准则 ,讲究求真务实、记大略小。《续资治通鉴长编》、《宋史》多采用欧碑内容 ,众多宋人笔记与欧碑记载一致 ,可相互参验。欧碑在为后世保存珍贵史料的同时 ,也留下了珍贵的史识。对欧碑不能一概而论 ,当分类研究。友朋、名臣类碑志最有份量 ,亲属、女性类亦有佳篇 ,宗室类多流于类型化、概念化的记叙 ,价值不高。庆历情结和洛阳情结 ,欧挥之不去而刻骨铭心 ,对其碑志文创作产生十分重要的影响。欧从韩碑 ,更从《史记》中汲取丰富的营养 ,友朋、亲属类碑志情挚意浓 ,独具风神 ,最富艺术魅力。
