三度理論-
This system is operated on the platform of unix ( ibm aix ), using powerdesigner as the modeling tool, based on the db storage of oracle9i, carried out etl works with datastage, built multi - dimension cube and laid out the result upfront by cognos. design and research of the whole dw system was deeply and particularly set forth here, this may make help to unicorn ' s dw project period 2 on theory
本系統以unix （ ibmaix ）操作系統為開發平臺，使用powerdesigner為建模工具，基於oracle9i的數據庫存儲，以datastage進行etl操作，以cognos作為多維立方體生成及前端展示工具，對整個數據倉庫系統的設計和研究做了深入的分析和詳細的闡述，為數據倉庫二期工作提出了理論上的幫助和建議。 -
This paper founds mathematical model of twin - floater ocean wave generate electricity device, and analyzes primary parameters on the base of mathematical model for searching the optimal solution during designing this electricity device. it presents the method calculating the ocean wave forces on the several ideal floaters such as cube, vertical cylinder, horizontal cylinder, sphere by the theory that froude - krylow presupposition calculates a big diving body
在研究浮子幾何形狀與浮子所受波浪力的關系的過程中，本文利用弗汝德-克雷洛夫假定法計算大尺度潛體上的波浪力的思想理論來推導作用在幾種常見理想浮體：長方體、垂直圓柱體、水平圓柱體和球體上的垂直波浪力。 -
Then, the dielectric targets ' electromagnetic scattering is researched. an important principle of electromagnetic field theory - - equivalent theory is introduced. as well as the conducting target, the geometrical model of the dielectric target should first be built, then triangular patches are used to model the surface of the dielectric target. different from the conducting target, there has not only equivalent electric current but also has equivalent magnetic current on the surface of the dielectric target. so now should built two equations - efie and mfie to obtain the unknown current coefficients. the rcs of dielectric sphere, dielectric cylinder, dielectric cube are calculated respectively
其次，本文研究了介質目標的電磁散射，介紹了電磁場理論的一個重要的原理? ?等效原理。與導體目標一樣，先建立介質目標的幾何模型，然後用三角形面元模擬介質表面。與導體目標不同的是，在介質表面除等效電流外，還有等效磁流，因此需建立兩個方程? ?電場積分方程（ efie ）和磁場積分方程（ mfie ）來求解未知的電磁流系數。
