    • Embodiments of performing beam forming processing based on sampling data in an ultrasound system are disclosed. The ultrasound system includes an ultrasound data acquisition unit configured to form a receive signal based on an ultrasound signal reflected from a target object, perform an analog-to-digital conversion on the receive signal to form sampling data, select pixels, which the respective sampling data are used as pixel values thereof among the plurality of pixels, cumulatively assign the corresponding sampling data to the selected pixels and perform beam forming upon the cumulatively assigned sampling data for the respective pixels to form receive-focused data.

    • A method of preparing silica aero-gel powders having a short preparation time and stable preparation processes. In the method, the silica aerogel powders are generated by using a water glass solution, an inorganic acid, an organosilane compound and an organic solvent. The method includes dispersion-solution generating, gelating and solvent exchanging and drying. In the dispersion-solution generating, a dispersion solution is generated by dispersing the water glass solution and the organosilane compound in the organic solvent. In the gelating and solvent exchanging, silica hydrogel is generated by adding the inorganic acid to the dispersion solution and simultaneously performing gelating and solvent-exchanging. In the drying, the silica aerogel powders are generated by drying the silica hydro-gel.
    • 一种制备具有较短制备时间和稳定制备方法的二氧化硅气凝胶粉末的方法。 在该方法中,通过使用水玻璃溶液,无机酸,有机硅烷化合物和有机溶剂来生成二氧化硅气凝胶粉末。 该方法包括分散溶液产生,凝胶化和溶剂交换和干燥。 在分散液生成中,通过将水玻璃溶液和有机硅烷化合物分散在有机溶剂中而产生分散液。 在凝胶化和溶剂交换中,通过向分散液中加入无机酸,同时进行凝胶化和溶剂交换,生成二氧化硅水凝胶。 在干燥过程中,通过干燥二氧化硅水凝胶来生成二氧化硅气凝胶粉末。
