1. symmetry in spectrum space of isotonic oscillator and two-photon parametric model
   同調(diào)諧振子譜空間上的對稱性和參量雙粒子模型
2. firstly, this article introduces the transforming principle and means from airspace to angular spectrum space, then it calculates square hole diffraction, at last it compares the theoretical calculation with the experimental result, which turns out to be good and fit
   本文首先介紹了由空域到角譜域的變換原理和方法，然后對方孔衍射作了計算，并同實驗結(jié)果作了比較，結(jié)果表明兩者十分吻合。
3. on the other hand, the multi-level fast mutipole algorithm ( mlfma ) which based on the integral equation method can obtain the result with great accuracy, but this method accounts in all the couplings between every sub-scatter objects, it needs much more to store all of the information, and because of the rigorous integral on the spectrum space the computational complexity is also enormous
   相對于一些傳統(tǒng)的方法如幾何光學(xué)方法,幾何繞射方法,彈跳射線方法有著更高的精度和更廣的適用范圍。但是由于其基于積分方程方法,需要對全局中所有的子散射體之間的相互耦合加以考慮,從而導(dǎo)致在求解電大尺寸目標(biāo)的散射問題時需要巨大的存儲空間。同時由于其在譜域上嚴(yán)格積分導(dǎo)致計算量也很大。
4. the space observation in soft x-ray and extreme ultraviolet ( euv ) region is an important portion of the space astronomy and an effective solar observation method developed increasingly . in this thesis we designed a euv multi spectrum space solar telescope ( eut ) based on the requirement of high angular resolution and wide field of view for solar observations; investigated the transmission performance of eut; invented a method of eut pointing calibration on the space orbit and solved the high precision pointing calibration problems; constructed a prototype of 17.1nm telescope, tested the possibility of eut design, and developed some cutting-edge techniques
   本文根據(jù)空間平臺上高分辨率對日觀測的需要，設(shè)計出一種可以在四個極紫外波段對日同時成像多光譜太陽望遠(yuǎn)鏡(eut)；研究了極紫外(euv)波段太陽望遠(yuǎn)鏡光學(xué)傳輸特性；提出了真空紫外波段在軌指向的標(biāo)定方法，解決了高精度指向標(biāo)定問題；研制出一臺17.1nm望遠(yuǎn)鏡的地面樣機(jī)，驗證eut設(shè)計的可行性，攻克了部分關(guān)鍵的技術(shù)難關(guān)；為進(jìn)一步的研究工作奠定了基礎(chǔ)。
