Introducing the Darwin's method of treating x-ray diffraction in crystals into Bragg diffraction for multilayer structure, a series of analytical expressions are obtained, which can be used to calculate the reflectivity, the Darwin's width, the minimum number of periods and the energy resolution.

V! X:{5 N/ l6 _/ P: S With park as the major platform for industrial development, the Longping Hi-tech Park's marching steps will be brisker. We aim at the park's completed area reaching over 10 sq km by 2010, the value of industrial output 18 billion Yuan, 100 hi-tech enterprises, and a national model hi-tech park with intensive high technologies and reputation.

Libermann.The early researcheson this kind of manifolds were closely related to Physics and Mechanics.But since1991,S.Kaneyuki published his result on the algebraic condition for the existence ofinvariant〓structures on a coset space,Lie theory has played the most impor-tant role in the study of this kind of manifolds.In particular,dipolarizations in a Liealgebra are closely related to the homogeneous〓manifolds.Dipolarizationsin semisimple Lie algebras and the homogeneous〓manifolds associated withthese dipolarizations have been studied by S.Kaneyuki,Z.X.Hou and S.Q.Deng.Inthe partⅡ of this thesis we study the dipolarizations in some quadratic Lie algebrasand the homogeneous parakahler manifolds associated with these dipolarizations.

Libermann给出的，早期的有关类流形的研究与物理和力学密切相关，自从1991年金行壮二发表了陪集空间上存在不变仿凯勒结构的代数化结果后，李群及李代数理论在这类流形的研究中起着主要作用，特别地，李代数的双极化与这类流形密切相关，半单李代数的双极化的相关几何，金行壮二，候自新和邓少强等人已作了研究，二次李代数是比半单李代数更广且带有非退化不变双线性型的李代数，本文主要研究了二次代数的双极化及相关几何。

On December 30, 2005, Daystar completed shipments of its TerraFoil and TerraFoil-SP solar cells. Nearly 500, 10cm x 10cm TerraFoil cells were shipped to Titan Energy in India, the contract PV module manufacturer of DayStar's first commercial customer, Blitzstrom GmbH, in Germany. A second shipment of over 300 cells, including a variety of smaller size TerraFoil-SP solar cells, was provided to Micro Energy Group of Zuhai, China, DayStar's second commercial customer. These cells will be used to produce a series of unique PV module prototypes for use in MEG's expanding line of solar powered consumer products.
