XSI 表达式的动画应用（四） 自动化你的角色

在动画制作过程中，有很多物体的运动是相关联的，比如：车子的行进和车轮的旋转，齿轮间的相互咬合，台灯的亮度和开关的旋转等等。类似于这种情况如果分别记录各自的动画将会很难配合协调，比如车子和轮子随着车子行进速度的改变，轮子的动画将很难调节。这时候我们需要利用表达式为车子的移动和轮子的旋转建立一种数学上的联系，使角色半自动化。这当中需要用到的仅仅是初中数学课堂上的一些公式。我们将通过这个例子来对角色进行自动化设置，从而简化动画制作的流程，使我们能够专心地对动画中有情趣的部分进行调制，而将一些繁琐的运算交给电脑来完成。[编者按]     

Preparation and Photolunlinescence of Ordered ZnO Nanowire Arrays

Ordered ZnO nanowire arrays embedded in anodic aluminum oxide (AAO) membranes were fabricated by electrochemical deposition of Zn(NO3)2+H3BO3 solution in a boiling bath. Scanning electron microscope (SEM) and transmission electron microscope (TEM) observation results show that the polycrystalline ZnO nanowires with diameters around 100 nm were uniformly assembled into the ordered nanochannels of the AAO. The results of the investigation into photoluminescence (PL) and electronic paramagnetic resonance (EPR) measurements reveal that the interfaces between the ZnO nanowires and the pore walls of the AAO create a lot of oxygen vacancies, which are responsible for the green light emission (peaking around 512 nm) and the huge enhancement of the PL emission.     

Corner block list representation and its application with boundary constraints

Floorplanning is a critical phase in physical design of VLSI circuits. The stochastic optimization method is widely used to handle this NP-hard problem. The key to the floorplanning algorithm based on stochastic optimization is to encode the floorplan structure properly. In this paper, corner block list (CBL)-a new efficient topological representation for non-slicing floorplan-is proposed with applications to VLSI floorplan. Given a corner block list, it takes only linear time to construct the floorplan. In floorplanning of typical VLSI design, some blocks are required to satisfy some constraints in the final packing. Boundary constraint is one kind of those constraints to pack some blocks along the pre-specified boundaries of the final chip so that the blocks are easier to be connected to certain I/O pads. We implement the boundary constraint algorithm for general floorplan by extending CBL. Our contribution is to find the necessary and sufficient characterization of the blocks along the boundary repre     

Thermal conductivity of （Sm1-xLax）2Zr2O7 （x=0, 0.25, 0.5, 0.75 and 1） oxides for advanced thermal barrier coatings

Pyrochlore oxides of general compositions, A2Zr2O7, where A is a 3+ cation (La to Lu), are promising candidate materials for ap-plications as high temperature thermal barrier coatings because of their high melting points, high thermal expansion coefficients, and low thermal conductivities. In this study, oxides of Sm2Zr2O7, (Sm0.75La0.25)2Zr2O7, (Sm0.5 La0.5)2Zr2O7, (Sm0.25La0.75)2Zr2O7 and La2Zr2O7 were prepared by solid reactions at 1600 ℃ for 10 h using Sm2O3, La2O3 and ZrO2 as the reactants. The phase compositions of these ceramic ma-terials were analyzed by X-ray diffractometer (XRD) and fourier transform infrared spectroscopy (FT-IR) methods, respectively. The micro-structure was observed by scanning electronl microscope (SEM). The thermal conductivities of these ceramic materials were measured using laser-flash method. XRD and FT-IR results showed that pure ceramic materials with pyrochlore structure were prepared successfully. SEM results indicated that microstructures of these ceramic materials were dense and grain boundaries were very clean. The La2O3 doped Sm2Zr2O7 pyrochlores (Sm0.75 La0.25)2Zr2O7 and (Sm0.5 La0.5)2Zr2O7 had lower thermal conductivity than the undoped Sm2Zr2O7. The thermal conductivity of (Sm0.25La0.75)2Zr2O7 was found to be lower than that of La2Zr2O7. The results showed that these ceramic materials had the poten-tial to be used as candidate materials for TBCs.     

广场舞与农村妇女组织建设——以广东省TL村、CH村广场舞队为例

以广东省TL村和CH村的两支妇女广场舞队为调查对象,对比分析了两支农村广场舞队形成的外在因素、得以维持的团体动力、对广场舞队的内在认同和参与广场舞的个体因素的异同,进而探讨两个广场舞队组织的发展过程。虽然两支舞队都还存在各自的发展困境,但总的来说,增强了妇女的社会支持,有助于性别平等与妇女增权,长远来看,对社会建设和社会治理也具有积极的作用。     

《大数据时代》

正《大数据时代》是国外大数据系统研究的先河之作,本书指出,大数据带来的信息风暴正在变革我们的生活、工作和思维,大数据开启了一次重大的时代转型。本书用三个部分讲述了大数据时代的思维变革、商业变革和管理变革。本书明确指出,大数据时代最大的转变就是,放弃对因果关系的渴求,而取而代之关注相关关系。也就是说只要知道"是什么",而不需要知道"为什么"。这颠覆了千百年来人类

痛挽往昔 瞻望来者——巴米扬窟龛考

本文整理出巴米扬山谷遗址群的年代学证据,旨在重现大佛的历史与图像地位。首先介绍了巴米扬山谷遗址群的研究方法和年代阶段,接着讨论玄奘所见所录的大佛的原始配置,最后将三尊佛像放入其原始的图像志语境中去考查,认为涅檗像原应位于38米大佛和55米大佛之间。后者为宝装焰肩佛,其神格应为燃灯佛;38米大佛为释迦佛。而巡礼者所遵循的应是燃灯佛-释迦佛-涅粲佛-弥勒佛的绕拜顺序。
