使用美国国家标准与技术研究院（NIST）的DTSA - II软件包，针对适当的样品几何形状和电子束加速电压（扫描电子显微镜（SEM）为10或15 kV，扫描透射电子显微镜（STEM）为200 kV，透射电子显微镜（TEM）为200或300 kV）进行模拟，并用于基于钽M/锆L X射线峰比值建立回归方程。然后，将此回归方程应用于实验性能量色散X射线光谱（EDS）数据。选择这种方法是为了替代针对本文所使用的各种仪器上可分析的每种成分生成精确的标准，或者替代使用常见的无标样分析。虽然这种方法并非旨在进行真正的定量分析，但它旨在对本研究中分析的各种样品进行可靠的定性比较。
simulated for appropriate sample geometries and electron beam acceler- ating voltages (10 or 15 kV for SEM, 200kV for STEM, and 200 or 300 kV for TEM) using the NIST DTSA-II software package and used to develop a regression based on the Ta M/Zr L X-ray peak ratio. Then, this regression was applied to the experimental EDS data. This approach was chosen in lieu of generating precise standards for each composition amenable to analysis on each of the various instruments used herein or utilizing com- mon standardless analysis. While not aiming to be a true quantitative analysis, this approach rather is intended to allow robust qualitative comparison between the various samples analyzed in this work.
