摘要：以Ca(OH)2和磷化渣与氢氧化钠反应得到的Na3PO4为原料，在常温、超声波辅助下，控制Ca／P原子比为1.67、适当的Na3P04滴加速率和搅拌强度等条件，用SEM、XRD和HIR对目标产物的结构和粒度进行了分析。结果表明，用该法可获得纯度、结晶度、颗粒度和分散性均较好的羟基磷灰石粉体。 关键词：纳米羟基磷灰石；超声化学；烧结；磷化渣 下面是改过的。 (School of Chemistry and Chemical Engineering，Xiangtan University，Xiangtan 411105) Abstract: Nano hydroxyapatite was synthesized by chemical precipitation process under the conditions below: Ca (OH) 2 and Na3PO4 were used as raw materials, an ultrasonic oscillatator was used to oscillating the system, the atomic ratio of Ca and P was controlled as 1.67, Na3P04 was dropped at appropriate rate and stirring intensity. The structure and size of target product was analyzed by SEM photos, XRD and HIR. The results show that the product, which was obtained by standing the reaction solution at room temperature for one hour after titration, was washed with anhydrous ethanol to get hydroxyapatite powder with high purity and crystallinity, and the particle size and dispersion was good. Keywords: nano hydroxyapatite; sonochemistry; sintering；phosphating residue；calcium hydroxide |

科技文章还是用一般现在时多些，另外结果说明部分的定语从句部分缺少谓语动词。Abstract: Nano hydroxyapatite is synthesized by chemical precipitation process under the conditions below: Ca (OH) 2 and Na3PO4 are the raw materials with the atomic ratio of 1.67 between Ca and P, an ultrasonic oscillatator is used to oscillate the system, Na3P04 is dropped into the solution at an appropriate rate under stirring. The structure and particle size of target product is analyzed by SEM photos, XRD and HIR. The results show that the product, which is obtained by standing the reaction solution at room temperature for one hour after titration and washed with anhydrous ethanol, is the hydroxyapatite powder with high purity and crystallinity, and the particle size and dispersion are good.

One thing is quite sure that we wouldn't use "SEM photos", as people wouldn't use "XRD diagrams". The term "SEM photos" could be used during the discussions UNDER THE FOLLOWING CONDISTIONS: 1. you are referring to that particular photo; 2. you are talking about the photo itself instead of the contents of it; etc. well, you may have your own preferences.
