一个大的科研项目,从提出到立项,从制订实施方案具体到实施过程,从鉴定通过到生产实际应用,除了具体的科研业务活动外,还有与之紧密联系的组织管理工作和后勤工作等.这一科研过程不但形成了大量的科技档案,而且也形成部分行政管理性文书档案.因此,便出现了科研项目形成的文书档案归到哪里立卷好的问题. 相似文献

Due to the complex nature of multi-source geological data, it is difficult to rebuild every geological struc-ture through a single 3D modeling method. The multi-source data interpretation method put forward in this analysis is based on a database-driven pattern and focuses on the discrete and irregular features of geological data. The geological data from a variety of sources covering a range of accuracy, resolution, quantity and quality are classified and inte-grated according to their reliability and consistency for 3D modeling. The new interpolation-approximation fitting construction algorithm of geological surfaces with the non-uniform rational B-spline （NURBS） technique is then pre-sented. The NURBS technique can retain the balance among the requirements for accuracy, surface continuity and data storage of geological structures. Finally, four alternative 3D modeling approaches are demonstrated with reference to some examples, which are selected according to the data quantity and accuracy specification. The proposed approaches offer flexible modeling patterns for different practical engineering demands. 相似文献

中世纪西欧城市文学对女性爱情的表现受到了教会文学和骑士爱情的双重影响.情爱和性爱的完美契合和前后相继构成了女性爱情的两个方面,其中情爱是对骑士爱情的升华和背离;性爱是世俗爱情的再现,反映了当时西欧城市居民注重感官的审美情趣.情爱与性爱的并存反映了城市文学的作者力求突破教会和世俗的限制,追求自由和自主的个人快乐的新主张. 相似文献

Complicated geological structures make it difficult to analyze the stability of rock slopes, such as faults, weak intercalated layers or joint fissures. Based on 3D geological modeling and surface block identifying methods, an integrated methodology framework was proposed and realized to analyze the stability of surface blocks in rock slopes. The surface blocks cut by geological structures, fissures or free faces could be identified subjected to the four principles of closure, completeness, uniqueness and validity. The factor of safety(FOS)of single key block was calculated by the limit equilibrium method. If there were two or more connected blocks, they were defined as a block-group. The FOS of a block-group was computed by the Sarma method. The proposed approach was applied to an actual rock slope of a hydropower project, and some possible instable blocks were demonstrated and analyzed visually. The obtained results on the key blocks or block-groups provide essential information for determining potential instable region of rock slopes and designing effective support scheme in advance. 相似文献

"新批评"流派兴起于美国,但它的源头却在英国.艾略特和瑞恰慈作为开创者,他们从逻辑实证主义倾向、对立调和有机论的影响和亚里士多德的渊源三方面为"新批评"的产生和发展提供了理论支持,瑞恰慈为"新批评"思想的形成做出了贡献. 相似文献

美国西进运动与中国西部开发是区域经济发展史上的两次壮举,是美中两国针对国内发展不平衡的状况所采取的应对措施.通过对二者的历史背景和演进过程进行分析后发现,西进运动在政府职能定位、市场体系建设、农业发展和工业化推进等方面对中国西部开发具有借鉴意义,通过对二者进行比较,可以加深我们对西部开发意义的理解. 相似文献
