The Macroregional Control during the Medieval China — A Case Study on Long You Dao in Tang Dynasty

区域考察是研究中国历史的重要视角，亦是本文的出发点。但在区域的分划上，本文并未选择自然地理区划、市场体系等作为划分依据，而是借助王朝国家所建立的大区控制体系以作为分区的依据。在此基础之上，再去探讨王朝国家试图控制大区的过程、方式及其意义，亦即将区域置于王朝国家对于地方控制的政治进程中进行讨论。本文即是以唐代的“陇右道”为切入点，通过大区的划分，控制与意义三部分进行考察，得出以下四点认识： （1）贞观十道划分时，将“陇右道”所辖的河、陇二十一州冠以“陇右”之名，是对前代“陇右”观念演变结果的继承。“陇右”一名初见于两汉之际，作为一种宽泛的地理观念，常与“河西”对举，大体指陇山以西，黄河以东地区...Regional research is an important perspective for studying Chinese history,and it is also the starting point of this dissertation. However, in the aspect of region division, the author does not choose to divide a region with certain standards, such as geographical features and marketing systems, but according to the macroregional control system that a dynastic state establishes. And on this basis,...学位：历史学博士院系专业：人文学院_历史地理学学号：1032012015370

汉魏南北朝时期“河陇”政治地理之演变——以“陇右”观念为中心

汉唐立基于“关中”,“陇右”为其重要门户,亦是沟通“关中”与“西域”乃至域外地区的重要交通枢纽。故对这一区域概念的梳理可使我们更好地认识中古时期西北地区的战略、交通格局。“陇右”一名初见于两汉之际,作为一种宽泛的地理观念,常与“河西”对举,大体指陇山以西,黄河以东地区。十六国时期,“都督陇右诸军事”一职的频繁出现,使得“陇右”一词开始向大区专名演变。且其所指地域亦不断扩大,跨越黄河,将“河西”囊括在内。与十六国不同,西魏、北周之时“陇右”督区或总管区皆有明确的属州,其辖区最大时囊括河、陇两地,这使得“陇右”一名在从宽泛的地理观念走向大区专名的同时,其所指代的地域范围亦日益明晰

唐宋时期沙州的城市形态与居住空间

唐宋时期敦煌地区分布着大量的州县乡堡,百姓“悉多城居“,“城外庄田,城内屋舍“的情况比较普遍。作为当地居民主要聚居地的沙州城则有子城、罗城之分,子城位于地势较高的西南隅,以便于控御与防守,其内设有衙署等建筑,罗城则主要分布着坊市以及寺观。生活于城中的部分百姓可以拥有一座一院式或两院式的完整宅院,而更多的则仅有1~2口屋舍,与别家合院的情况十分普遍

论我国人大立法审议机制的功能与优化

我国人大立法活动的重心应当从立法数量的增加转向立法质量的提升。立法质量决定法律运行效果,立法程序决定立法质量,立法审议是立法程序的核心环节。我国人大立法审议具有较为完整的制度架构,但制度的实际运行仍然未达到理想的状态。部分主体未能充分运用权限,导致另一部分主体功能扩张,产生了规范与功能之间的张力。具体体现在会议议程的实际决定权偏移、统一审议中委员会功能放大和议事成员的实际议事功能较弱等三个方面。实际规范与功能之间的偏差可以通过应然的价值取向作为基准予以协调。立法审议应当具备公正、科学、民主和效率等价值基础,可以通过进一步明确统一审议的职能分工、完善立法听证程序、设置立法辩论程序等途径优化我国人大立法审议机制。国家社会科学基金项目“我国地方立法权配置的理论与实践研究”(13BFX024

微课程在初中信息技术教学中的运用

传统的信息技术教学存在着很大的局限性，教师无法进行有针对性的教学，但微课程的出现，不仅打破了传统教学模式的局限性，而且也满足了学生的学习需求。微课程属于一种新型的教学方式，得到了教师的普遍认可，同时相比较传统的教学模式，学生的学习效率与教师的教学效率都得到了很大的提升。</jats:p

下料问题的研究与应用

This thesis develops and investigates heuristic approaches to the classical and practical Cutting Stock problems. In particular, we concentrate on hill climbing and dynamic programming techniques, incompletely enumerative and sequential heuristic procedures.There are in total four cutting problems to be solved in this thesis. They are 1D and 2D Knapsack Problems, 1D and 1.5D Cutting Stock Problems. In 1DKP, we develop a hill climbing method, with high approximation ratio and relatively low computational complexity in solving the 1DKP of special data structure as we have described. In 2DKP, a heuristic dynamic-programming method is proposed for solving efficiently an unconstrained non-staged 2D knapsack problem. Compared with the traditional dynamic programming, the algorithm gives a high percentage of optimal solutions (93%) with a much lower computational complexity. The worst-case performance of the algorithm is evaluated. Some theoretical analyses for the algorithm are performed. Computational results are given for small and medium-sized problems. After solving the 1D and 2D Knapsack Problems, we focus our attention on a kind of 1DCSP proposed by a factory in Macao. Although this is a classical 1DCSP, the problem has so large a size that tradition Column Generation technique is no longer applicable. Thus we developed an incompletely enumerative algorithm to solve the problem. Theoretical analyses and numerical experiments show that this incompletely enumerative algorithm is an approximate implicitly enumerative solution.Finally, an iterative sequential heuristic procedure is developed to solve the general real-life 1.5DCSP. An SHP algorithm is used firstly to generate a feasible solution to the general problem. Then the SHP is improved into an iterative SHP, in which different strucures for a single cutting pattern are found by adjusting four adjustable parameters given in the SHP. With this method, the search space is enlarged and the probability that an optimal solution is found is highly improved
