ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

使用MapX在无人机导航系统中添加能够处理矢量地图数据的地理信息模块，可以显著地提升系统的性能；文章对如何在矢量地图下进行无人机导航与任务规划进行了研究，完成对地理信息系统中矢量地图的基本控制和操作，并在地理信息图上进行航线的设定与修改；另外，针对二维矢量地图无法对无人机进行三维空间定位的问题，文章通过在无人机导航系统中添加高度位置显示模块，用二维平面地图与高度图相结合的方式来实现对无人机位置的三维定位；通过在无人机仿真实验系统中的使用，证明了该系统能高效、直观地对无人机飞行进行监视与控制。

A research survey conducted by Morten Kringelbach, senior fellow at Oxford University's department of psychiatry, found the orbitofrontal cortex could be a "new stimulation target" to help people suffering from anhedonia, an inability to experience pleasure from such activities.

牛津大学精神病系的资深成员Morten Kringelbach做了一个研究调查，发现眶额皮层可能是的一个&新的刺激靶点&，对那些无法体会相关快感的所谓&快感缺乏症&的患者，该区域意义非凡。而快感缺乏是一种体会来自上述那些活动的快乐的能力缺陷。

We might instead consider that they are younger, smarter, less bureaucratically encumbered, and more energetic versions of ourselves, and best able to learn by working on questions that turn them on, even if we might not be able to answer them or even understand them!

我们或许应该从另外一方面来考虑，他们是更年轻的、更聪明的、更不会被官僚作风羈绊的、更有活力的我们的投影，能让他们学到最多的方式是在研究那些能挑起他们的兴趣的题目，即使我们无法回答他们或甚至于了解他们。

Based on the researches of system factors, system characters and the influence of market structure to market behavior, the chapter points out the characteristics and rules of china bond market system variance. On account of the Promoting Effect Government Dominated behavior, compellent system variance runs through the evolution of market structure and act on it. Although derivational system variance also works, it can't be the dominant because of the long variance time and high cost.

根据制度变迁理论研究债券市场结构的制度成因、特点及其对于市场结构和行为的影响，指出中国债券市场制度变迁的特点和规律，由于在中国债券市场的发展过程中，政府主导行为具有明显推动效应，强制性制度变迁始终贯穿于市场结构演变的过程中，并对其形成重要作用；诱致性制度变迁虽然也穿插其中，但由于其变迁时间长、成本高等特点，无法形成主导力量。

The conventional study is based on mathematical models of process. Because of complexity of fault occured, it is difficult to run and dualize rigorous models. Hence, the troubleshooting isn't straight and easy to implement.

正因为如此，国内外对蒸馏过程故障诊断进行很多的研究，但多采用传统的建立过程数学模型的方法，由于过程工艺流程的复杂性，难以建立准确的数学模型，无法对故障作出直接、准确的诊断。

With the different laboratory compaction method and the real pavement, the study of particle stability and density indicated that Marshall compacted specimen can not simulate the real pavement, the rolling and gyratory compacted specimen are the most similar with real pavement, vibrating compacted specimen is second similar with the real pavement.

针对不同试验室压实方法成型试件和实际路面，从集料颗粒的稳定性和密实程度两个角度的对比研究表明，马歇尔击实成型试件法无法有效模拟实际路面，表现在其粗集料颗粒主轴取向无统计规律且与实际路面不具相关性；轮碾压实和旋转压实试件具有与路面最接近的稳定性和密实程度；振动压实次之，虽然表现出具有使颗粒较好均匀分散成型的特点，但其粗集料颗粒骨架的稳定性不够理想，致使其密实程度相对不高。

We observed that the probationary teacher has very strong motives in learning to teach. However, his intention of teaching diagnostically was defeated by his relatively weak PCK and easily impacted by the traditional instruction approach at the beginning stage of his probation. His social identity within the community of practice is heteronomous. He was not able to practice intentionally at this early stage.

研究发现，这位实习教师有强烈的内发学习动机，但是实习刚开始时，由於他缺少诊断教学实作经验，教学知能尚不足，想要引起师生互动的教学容易受到挫折，容易受到辅导老师和学生对他的教学感受的影响，导致无法有效提升他的教学知能。

As my own studies have advanced,I have been increasingly impressed with the functional similarities between insect and vertebrate societies and l ess so with the structural differences that seem,at first glance,to consti tute such an immense gulf between them.

随着我的研究不断深入，我对昆虫和脊椎动物群落之间的功能类似性印象愈来愈深刻，而对结构上的差异印象愈发淡漠，虽然这些结构上的差异初看上去似乎构成了二者间一条无法愈越的鸿沟。

These "problem properties" from the causes can be divided into seven categories: The first is caused by disordered development; second is not strictly project approval, business-to-project development funds are not implemented; third is absconding money led to real estate developers failed to materialize; four the project to rely on bank loans, the state tightened money supply, no follow-up support for the construction funds for construction; five real estate policy is due to gradually improve over the past administrative allocation of land are required to pay a large number of land transfer and value-added tax to pay the gap too big , developers can not afford to pay; Sixth, the lack of project feasibility study, sales difficult construction projects shall not be able to implement; Seven developers for other economic cases sealed by the court project.

这些&问题性质&的原因可分为七类：第一是所造成的无序发展；二是不严格项目审批，企业对项目的开发资金不落实；三是潜逃钱导致房地产开发商未能实现；四个项目依赖于银行贷款，国家收紧货币供应量，没有后续支持建设建设资金；五年房地产政策是逐步改善，在过去的行政分配土地都必须支付了大量的土地转让和增值税支付的差距太大，开发商无力支付；第六，缺乏项目可行性研究，销售困难的建设项目将无法实施；七开发其他经济案件由法院密封项目。
