摘要：
The instrumental function of a high resolution asymmetric X-rays diffraction equipment was investigated. The broadening contributions of focal spot size, monochromator, specimen transparency, geometrical effects and thermal noise of the position sensitive detector were analyzed and convoluted to synthesize the line profile shapes on a wide angular range, Taking into account the real instrumental function, the anisotropic shape of TiO2 aerogels nano-crystals was determined by line profile analysis and whole pattern fitting.
