A new method is applied in comparing experiment. For real interferometric data of annular wave front  the SEIDEL aberration calculated in different ways is removed from the original wave front. Residual astigmatism aberration in annular polynomial way is close to zero  but defocus and sphere aberration are 0.002709  -0.00182. The residual SEIDEL using annular polynomial is least. Data used in comparison shows that Zernike annular polynomial is more accurate and meaningful for the decomposition of aberrations and the calculation of Seidel aberrations in annular pupil. The calculation in astigmatism aberration is most accurate and those in defocus and sphere aberration are least accurate  when the first 9 terms are used in approximate solving SEIDEL. More coefficients are needed to obtain the real SEIDEL. 2010 IEEE.   Lattice correspondence and fivefold twins of the orthorhombic (2/1, 1/1) and (1/0, 2/1) approximants in a Ga-Fe-Cu-Si alloy 期刊论文 METALLURGICAL AND MATERIALS TRANSACTIONS A-PHYSICAL METALLURGY AND MATERIALS SCIENCE, 1999, 卷号: 30, 期号: 3, 页码: 697 Ge, SP; Kuo, KH 收藏  |  浏览/下载：26/0  |  提交时间：2013/09/18 DECAGONAL QUASI-CRYSTAL  RESOLUTION ELECTRON-MICROSCOPY  AL-MN  CLOSE RELATIONSHIP  PHASES  AL3MN  DIFFRACTION  PD   Structural model of the orthorhombic non-Fibonacci approximant in the Al12Fe2Cr alloy 期刊论文 ACTA CRYSTALLOGRAPHICA SECTION B-STRUCTURAL SCIENCE, 1997, 卷号: 53, 页码: 587 Sui, HX; Liao, XZ; Kuo, KH; Zou, XD 收藏  |  浏览/下载：20/0  |  提交时间：2013/09/24 DECAGONAL QUASI-CRYSTAL  RESOLUTION ELECTRON-MICROSCOPY  X-RAY-DIFFRACTION  AL-CR SYSTEM  CLOSE RELATIONSHIP  PHASE  AL3MN  QUASICRYSTALS
