The following are the major work in this thesis which has been studied and still needs to be studied further in the future: 1 An improved adjoint variational method is developed, thus it can be applied to the LAGFD-WAM Wave Numerical Model for data assimilation; 2 A linear evolution equation of spectral perturbation is derived in order to analyze its increasing or decreasing mechanism.
本论文主要完成了以下几个方面的研究: 1)建立了推广形式的共轭变分同化方法,使之能够应用于LAGFD-WAM海浪数值模式; 2)导出了扰动谱线性演化方程,分析了扰动谱增长、衰减机制,考察了涌浪情况下扰动谱的持续时效问题及风浪情况下扰动的演变过程; 3)利用波谱共轭方程初步分析了同化模型中距离泛函的敏感性及敏感区域空间分布; 4)将推广的共轭变分方法应用于海浪谱能量平衡方程,建立了连续形式的海浪同化模型,特别是严格导出了风输入、破碎、底摩擦、波波非线性相互作用和波流相互作用各源函数的共轭源函数表示式; 5)分别进行了波谱层次上和有效波高层次上的同化试验,并对数值结果进行了分析。

The structure shown in the figure : The governing body received direct or roller drying cylinder, as the main components of the rotation; After finishing the outside of the sphere, Bottom Cover and soak spherical carbon graphite seal ring joint seal reliable seal friction deputy, Sealing ring in the spherical shell of its annular space sliding, in addition to oil-free bearings and with the close cooperation of Shell, Rotating connector so that the free support, and therefore do not require a high level of accuracy installed; Spherical seal ring wear, Spring means of pressure at any time in advance to receive compensation, compensation for the shell slowly moved backward, accessible through the tube outside the inscription on the line to observe the seals wear; When steam, Oil flows through the media or other spherical sealing ring and oil-free bearings, the formation of thin liquid film, sealing and lubrication, thereby reducing friction and wear, extending the service life.
其结构如图所示:外管体直接接到辊子或烘筒上,为主要的旋转部件;经过精加工的外管本球面、底盖和浸泡碳石墨球面密封环共同组成密封可靠的动密封磨擦副,球面密封环在其壳体内的环形空间中滑动,加之无油轴承与壳体的密切配合,使旋转接头自由支撑,故对装机精度要求不高;球面密封环磨损后,借助于弹簧的预压力随时得到补偿,补偿时壳体缓缓向后移动,并可通过外管体上的刻线观察到密封件的磨损程度;当蒸汽、油或其它介质流经球面密封环和无油轴承时,形成一层很薄的液膜,提供密封和润滑,从而减轻了摩擦和磨损,延长了使用寿命。

We used ITO glass substrate and high purity(99.99%) titanium , put to use sputtering process, add to high purity O2 make it complete the best structure film and the thickness about 1400 . By way of 500℃ anneal could got a better anatase phase, this result could easy reaction with electrolyte to increase electron-transferred. Used as spin casting covering PR on ITO substrate, transferring patterns of array circular shapes on a mask to photography, used optimize temperature and time to hard bake. Finally used HCl to etching underexposed TiO2 area, and acetone to tripper top PR, make it to accomplish pillars shape TiO2 electrode.
本研究使用ITO玻璃基板为底材在以高纯度钛(99.99%)为靶材,利用溅镀方式通入纯氧使其行成高纯度TiO2镀於ITO基板上行成厚度约1400的薄膜,且经500℃高温烧结使其行成最强的锐钛矿结晶相,此晶相有利於与电解液反应进而增加电子的转移,提升太阳能电池最佳的效率,在以旋转涂布方式铺上光阻,以矩阵排列的圆孔光罩曝光、最佳的温度及时间来烘烤、显影后;使用盐酸以等向性湿蚀刻方式蚀刻未曝光之TiO2区域,最后利用鈵铜将最上层光阻去除,使其行成柱状TiO2的电极。
