摘要：为分析地震作用下框架锚杆支护结构的动力响应,以某中跨立柱单元为对象,考虑边坡加速度放大效应对支护结构上动土压力的影响,将立柱简化为抗弯刚度均匀的竖向杆件,依据锚杆工作机理将自由段简化为线弹簧,考虑土体阻尼影响将锚固段简化为线弹簧与牛顿粘壶,支护结构坡脚处简化为固端约束,进而建立支护结构动力响应简化模型.运用力法与图乘法对支护结构动力响应进行求解,建立支护结构动弯矩和动位移与坡高之间的关系.模型计算方法与Geo-Studio有限元软件结果对比,验证模型的合理性与可行性,为此类工程设计与地震作用下支护结构动力研究提供相应的参考.

摘要：轴对称矢量喷管为复杂的空间多链路机构,是推力矢量技术的核心。为研究其运动规律,将空间机构位置分析法、解析几何法和环路矢量法相结合,建立了轴对称矢量喷管的空间运动学模型。利用数值仿真实现了其运动姿态的仿真,并通过与ADAMS仿真结果对比,验证了该模型的正确性,进而获得轴对称矢量喷管在不同驱动方式下的位姿以及喉口和喷口的面积变化规律。结果表明:喉口状态和喷管运动状态对喷管面积比均有影响,面积比随着A9作动筒的同步伸长呈明显单调递增状态;A9作动筒异步驱动时,喷管面积比变化较小,喷口矢量偏转角角速度与作动筒运动速度呈比例关系,截面形状由圆形逐渐变为空间上扭曲的椭圆形;拉杆尺寸对喷管机构的面积比变化范围有明显影响,拉杆每增大(或减小)1 mm,面积比变化区间整体上移(或下移)0.025。仿真结果有助于了解喷管的运动规律,可为喷管的参数化分析及优化设计提供理论依据。

摘要：主要介绍自由识别和指定位置识别2种自动识别船体型线的方法。运用AutoLISP语言直接读取绘制二维型线时所有控制节点的二维坐标,获取二维型线上指定位置插值点的二维坐标,并利用型线与指定位置在船体上的实际位置的关系将这些节点坐标转化为三维型值。通过算例验证采用该方法求取船体型线三维型值的高效性和准确性,以及导入Solidworks软件进行三维建模生成船体曲面的可行性,为船舶设计由二维向三维转化提供参考。

摘要：为探讨养老机构老年人自我效能感与心理一致感的相关性,采用便利抽样法选取昆明市8所养老机构的212名老年人为研究对象,利用自行设计的一般资料调研问卷、一般自我效能感量表与心理一致感量表(SOC-13)进行横断面调研。结果显示,养老机构老年人自我效能感得分为24分,心理一致感得分为(60.63±13.57)分,自我效能感与心理一致感及其可控制感、可理解感、有意义感维度均呈正相关关系。养老机构老年人自我效能感处于中等水平,心理一致感处于较低水平,两者均有待提高。自我效能感越高的老年人心理一致感越好。可根据老年人自我效能感水平采取针对性的干预措施,进而提升其心理一致感,促进养老机构老年人的心理健康发展。

摘要：This paper presents a macroblock-level (MB-level) decoding and deblocking method for supporting the flexible macroblock ordering (FMO) and arbitrary slice ordering (ASO) bit streams in H.264 decoder and its SOC/ASIC implementation. By searching the slice containing the current macroblock in the bit stream and switching slices correctly, MBs can be decoded in the raster scan order, while the decoding process can immediately begin as long as the slice containing the current MB is available. This architectural modification enables the MB-level decoding and deblocking 3-stage pipeline, and saves about 20% of SDRAM bandwidth. Implementation results showed that the design achieves real-time decoding of 1080HD (1920×1088@30 fps) at a system clock of 166 MHz.

摘要：Tolerance design, including tolerance analysis and distribution, is an important part of the electronic system’s reli- ability design. The traditional design needs to construct mathematic model of material circuit, which involves large amount of workload and lacks of practicability. This paper discusses the basic theory of electronic system’s reliability tolerance design and presents a new design method based on EDA (Electronic Design Automatic) software. This method has been validated through the application research on reliability tolerance design of the DC hybrid contactor’s control circuit.

摘要：The social gender theory is a historical analysis method which is benificial to explore the system of human organization activities around "male"or "female" activities. Historically, the process of human socialization is also a process of social gender institutionalization. Therefore, the paper tried to analyze the connotation of ethnic women"s costume from the social gender perspective to help people realize further the women"s state in sexism society and value in ethnic group constructing and developing. Firstly, the paper sets forth the characteristic of "group" of ethnic people female costumes. The next, the paper explored the costume how to set up a system of ethic standard in inner group so as to maintain the social order. Subsequently, the paper points out, with the rapid evolution of society, more and more ethnic people men participate cities construction and outer social activities. Consequently, most of minority men wear modern clothing instead of their traditional clothing, only women still insist in wearing the traditional clothing. Finally, according to research above, the authors consider that ethnic people female costumes emerge strong gender content which reflects more constraints rather than equality between men and women. Besides, it is certain that women have irreplaceable value in ethinc group construction and development.

摘要：[研究意义]明代皇室冠礼首服艺术探析对现代婚礼服以及现代成人礼首服的重新设计和发展起到借鉴和启示意义。[研究方法]文章利用文献研究,考古类型学、图像学分析方法对明代皇室冠礼首服造型,材质使用,装饰手法予以研究,总结其外在艺术表征,并探析其表征背后的内在原因。[研究结果与结论]明代皇室冠礼首服类型可分为两大类和五种型,其造型匀称独特、简洁和谐,面料的使用精致奢侈显示皇权地位;装饰造型细节差异成为凸显等级独特标识。其冠礼首服造型在时代更替过程中呈现出皇室阶层“宁古无时”与“惟新求奇”的矛盾审美思潮,其文化内涵表现出“王在礼下”与“皇权观念”的思想矛盾印证了中国古代皇权意识与礼仪制度之间的和谐与矛盾的复杂关系。
