| 摘 要： | 采用X射线CT(XCT)技术进行体积重构的研究方法,解决了异形泡沫金密度表征中体积难以精确测量的问题,密度表征结果为978.68mg/cm3。同时,为了研究该方法的有效性与不确定度,开展了XCT体积重构法与排水法对具有不规则外形橡皮泥样品的密度表征对比实验,结果表明两者之间的相对误差小于1%。

| Abstract: | Gold foam is one of the most important materials used in ICF experimental research, while it is hard to precisely measure the volume of the gold foam in its density characterization. Here we reported one method of volume reconstruction by using X ray CT technology. By using this method, the density of our prepared gold foam with abnormal surface is determined to be 978.68 mg/cm-3. To validate the accuracy of this method, comparison experiments between this method and a specific gravity bottle method have been performed by using plasticine samples. The results show that the relative error value is less than 1%. |
