SiO2 opal with face centered cubic structure is fabricated using a self-assembly method. Two different three-dimensionally ordered macroporous carbon materials are prepared using SiO2 opal as a template through "volume templating" and "surface templating" approaches, respectively. The final morphology of the sample can he controlled by the infiltration times.

Thus, in addition to the cousins Dorothy and Florence, Martin encountered two university professors, one of Latin, the other of English; a young army officer just back from the Philippines, one-time school- mate of Ruth's; a young fellow named Melville, private secretary to Joseph Perkins, head of the San Francisco Trust Company; and finally of the men, a live bank cashier, Charles Hapgood, a youngish man of thirty-five, graduate of Stanford University, member of the Nile Club and the Unity Club, and a conservative speaker for the Republican Party during campaigns - in short, a rising young man in every way.

于是除了陶乐赛和佛罗伦斯两姐妹之外，马丁在那里还见到了两位大学教授（一个教拉丁文，一个教英文）；一个刚从菲律宾回来的青年军官，以前曾是露丝的同学；一个叫梅尔维尔的人，是旧金山信托公司总裁约塞夫·相金斯的私人秘书。

That the location of the airport帕希姆happens to be in the center of Europe, from Hamburg, 120 km, Berlin 160 km, between the two major German cities have a sea port of iron supply and rail systems, but there is no air transport hub, Pa Fahim stop at the airport between the two cities, while Hamburg is Europe's second largest port, and the Baltic port of Rostock, Wismar, Lübeck circle at the airport, 100 km range, have a direct rail link, the multimodal transport is that it combines the advantages of.

庞玉良认为帕希姆机场的所在位置刚好是在欧洲中心，距汉堡120公里，柏林160公里，两个主要德国城市之间都有海、铁的货源的港口与铁路系统，但没有空运枢纽，帕希姆机场罢处于两城市之间，而汉堡又是欧洲第二大港口，而波罗的海港口罗斯托克、维斯玛、吕贝克在机场圈100公里范围之内，有铁路直接联系，这种多式联运结合是它的优势。

This dissertation involves the study of the growth dynamics of colloidal particles under unequilibrium and irreversibility condition. Firstly, it is of interest to investigate whether the ideal diffusion or reaction-limited aggregation universal behavior can be observed for the initially polydisperse practical system of basic yttrium carbonate as well. The fractal structure of basic yttrium carbonate aggregate cluster was observed using transmission eletron microscopy. The aggregation kinetics of basic yttrium carbonate colloids was studed using dynamic 1ight-scattering techniques. At 1.00mol/l NaCl solution the fast diffusion-limited aggregation behavior was observed with an increase in the aggregate size over time described by a power law. The aggregates are characterized by a fractal dimension D=1.82. The disordered and ramified cluster is consisted of primary colloidal particles and tenuous and more open. These are in good agreement with those observed for other colloidal system such as colloidal gold (1.86), silica (1.85) and polystyrene latex (1.82) in diffusion-limited aggregation from the static and dynamic light scattering by Lin. Therefore ideal diffusion-limited aggregation behavior can be observed in practical polydisperse system as well. Smoluchwski and fractal theories were used to obtain the aggregation rate constant for initially polydisperse system for the first time.

本论文研究胶粒的非平衡不可逆聚集动态学，分为两个部分，第一部分是通过实验研究一个新的初始多分散的碱式碳酸钇胶粒实际体系中，聚集标度性质的普适性，即使用透射电子显微技术观测聚集粒子簇的分形结构，使用动态激光光散射研究碱式碳酸钇胶粒的聚集动力学，胶粒带电而产生静电排斥作用使得碱式碳酸钇胶粒处于稳定状态，当加入电解质NaCl溶液时，碱式碳酸钇胶粒间的Debye-Hückel屏蔽距离缩短，从而降低静电排斥能垒，引起胶粒发生不可逆聚集，加入电解质NaCl的浓度为1.00mol/l时，碱式碳酸钇胶粒进行快速聚集，经历扩散控制聚集机理，形成结构疏松、更为开放的分形聚集粒子簇，其分形维数为1.82，碱式碳酸钇胶粒聚集增长动力学遵循幂函数增长规律，与Lin等使用静态激光光散射和动态激光光散射测量硅胶(1.85)、金胶(1.86)和聚苯乙烯胶乳(1.82)在扩散控制聚集状态形成聚集粒子簇的分形维数值以及粒子簇聚集增长的动力学规律相一致，表明胶粒聚集标度性质的普适性质在初始多分散的实际体系中也是存在的，首次由动态激光光散射的实验数据得到初始多分散胶粒分形粒子簇的聚集速率常数，并且其值与Smoluchowski聚集速率理论预期相符。

And an exact maximum likelihood registration algorithm is presented based on three-dimensional plane. This method contains two sets of partially separable variables (the actual target positions and the sensor registration errors) and provides a two-step recursive optimization algorithm to ensure fast convergence. Described by expressions:(5.26)?(5.39). It resolves the problems on Multiple-platform.

同时本文还推导出了三维立体投影的极大似然配准算法，算法包括两组部分可分的变量：实际目标位置和传感器的配准误差，利用两步递归优化算法对收敛速度进行了优化处理，实现过程可参阅式5.26～5.39，此算法解决了不同平台内多传感器配准过程中所存在的问题。

The Yankees, however, had taken advantage of three Seattle errors and staked Wang to a 3-0 lead after two. Seattle's Erik Bedard was unhittable after that, and retired the final 14 batters he faced, but with Wang on the mound — and Kyle Farnsworth, Chamberlain and Mariano Rivera after him — the Yankees didn't need the two insurance runs they got in the eighth.

反观洋基，在前两局就趁著水手的三次失误打下3-0给小民当本钱，此后水手的Erik Bedard就不再挨打，接连解决14名打者，但是这可是王小民在投球，后头的方师傅，张伯伦，李维拉也不赖，洋基根本不需要八局多打下的两分保险分。
