中文摘要	Quantitative convergent-beam electron diffraction method (QCBED) was applied to study the complex oxide, La/sub 2/3/Ca/sub 1/3/MnO/sub 3/. For this purpose, some modifications, including the consideration of symmetry operation, the image distortion correction and multi-start clustering global optimization algorithm, to the QCBED experiments and optimization program were explored according to the structure feature of La/sub 2/3/Ca/sub 1/3/MnO/sub 3/. The way to refine atomic position parameters and temperature factors (Debye-Waller factors) without an energy-filter is attempted with the diffraction intensity of high-order Laue zone. Based on these refined atomic position parameters and temperature factors, the nine structure factors of the low-index diffractions were refined by fitting the energy-filtered diffraction patterns with the improved QCBED method.
