校准工作矩阵──目标因子分析光度法同时测定氨基酸混合体系

open access: yes, 1995
本文提出一种应用传统目标因子分析法的实用技术。通过确认一个相应的校准工作矩阵可对混合样品中的各组分进行同时直接定量。对一批六组分氨基酸混合样品(各组分浓度为2.072~79.170μ/mL)的分析表明,各组分绝大多数的回收率均在10±10%之内 ...

The Impact of AI‐Assisted L2 Learning on Learners’ Emotions: A Meta‐Analysis

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT The scope of research on AI‐assisted second/foreign language (L2/FL) learning has expanded beyond learning outcomes to focus on learners’ emotional experiences. Despite their proliferation, existing empirical findings are inconsistent, and few studies have systematically synthesized the impacts of AI‐assisted L2 learning on learners’ emotional

EPBS对氚化钛薄膜中氚量及分布的初步分析

open access: yes四川大学学报. 自然科学版, 2013
近年来,我们致力于将氚$衰变诱发X射线谱分析(BIXS)方法发展成为一种准确测量含氚薄膜中氚量及分布的常规方法.该方法结合了蒙特卡罗模拟与Tikhonov正则法,近期已用于一系列氚化钛薄膜样品总氚量、深度分布的分析.增强质子背散射分析(EPBS)方法作为一种快速、无损的杂质成分含量及深度分布的分析手段,在本文中被用于该系列氚化钛薄膜样品的分析,并与相应的BIXS结果进行了比较,对分析中的有关问题也进行了讨论.
