因生产成本高、易引入溶液中的杂质、生产效率低等缺点而一直未能实现工业化生产。为了克服上述缺点，实现高效、简便、低成本、高质量地制得AB电子陶瓷粉体以适应现代技术发展的要求，本文采用室温下将A与B混合研磨，再在较低温度下煅烧的方法制得了AB物质的量比约为1.0、颗粒大小分布均匀、粒径在15～20 nm的AB纳米粉体。既克服了液相法在水溶液中制备易引入杂质、生产效率低等缺点，其煅烧温度比传统的固相法低了约400-600 ◦C。该方法未见文献报道。用XRD、SEM、TEM、FT-IR对产品进行了表征，并用TG-DTA对前躯体的煅烧反应过程进行了分析。

Due to high production costs, easy to introduce the impurities, and low productivity,it has not been able to achieve industrial production. In order to overcome these shortcomings, and to obtained AB electronic ceramic powders to meet the requirements of the development of modern technology in efficient, simple, low-cost, high-quality method. this paper will mix A and B at room temperature , and then calcined at lower temperature Methods, formative AB won the molar ratio of the system is about 1.0, particle size distribution and uniform particle size in the 15 ~ 20 nm nano-powders of AB. Not only overcome the liquid phase method in aqueous solution preparation of easy introduction of impurities, defects and low production efficiency, the calcination temperature of solid-phase method than the traditional low of about 400-600 ◦ C. This method not been reported in the literature. Using XRD, SEM, TEM, FT-IR of the products were characterized and used TG-DTA of the former body of the calcination reaction was analyzed

感觉楼上的像是用机器翻译的，语法，时态毛病不少，句式杂糅，如calcined；Not only ....but also 是连用的，这里却只有Not only ；Using XRD, SEM, TEM, FT-IR of the products were characterized and used TG-DTA of the former body of the calcination reaction was analyzed 这句太明显了
