This.s.udy explored a Bayes.an belief networks.(BBNs. approach, developing two dis.inct models.for prioritizing the s.ven indicators.related to the "rapid res.ons. to and mitigation of the s.read of an epidemic" category within the context of both the s.ecific category and the Global Health s.curity Index (GHs.index). Utilizing data from the 2021 GHs.index, the methodology involves.rigorous.preproces.ing, the application of the augmented naive Bayes.algorithm for s.ructural learning, and k-fold cros.-validation. Key findings.s.ow unique pers.ectives.in both BBN models. In the mutual value of information analys.s. "linking public health and s.curity authorities. emerged as.the key predictor for the "rapid res.ons. to and mitigation of the s.read of an epidemic" category, while "emergency preparednes. and res.ons. planning" as.umed precedence for the GHs.index. s.ns.tivity analys.s.highlighted the critical role of "emergency preparednes. and res.ons. planning" and "linking public health and s.curity authorities. in extreme performance s.ates. with "acces. to communications.infras.ructure" and "trade and travel res.rictions. exhibiting varied s.gnificance. The BBN models.exhibit high predictive accuracy, achieving 83.3% and 82.3% accuracy for extreme s.ates.in "rapid res.ons. to and mitigation of the s.read of an epidemic" and the GHs.index, res.ectively.

铜金二元系中超结构的形成与点阵间隔的变迁

本文用X射线衍射的方法全面地研究了Cu-Au二元系合金经不同时间（一个月、三个月、六个月、一年）熟炼后缓冷到室温,以及在300℃和600℃淬炼后的物相与相转变过程;精确地测定了点阵间隔,以研究其随成份和热处理的变迁;探讨了长周期超结构的堆垜周期同成份和温度的关系;并用保持不同热处理时间后淬炼的方法来研究等原子成份处的有序化过程。在上述的热处理条件下,整个二元系共出现了六种不同的相:α1是Au在Cu中的固溶体,α1′是相当于Cu3Au的超结构,α2是Cu在Au中的固溶体,α2′是相当于CuAu3的超结构,k是相当于CuAuⅠ的超结构,k′是相当于CuAuⅡ的超结构。值得注意的是,随着热处理时间的加长,有序区逐渐扩大,二相区逐渐缩小,在一年缓冷的合金,二相区几乎完全消失。因此作者认为:Cu-Au系的二相共存是处于介稳状态,以α2′相而论,最清晰的超结构线并不出现在化学计量成份而在68at.％Au。在等原子成份两边所出现的k′相,当合金经一年熟炼之后,一部分又变成了k相,在等原子成份处,k相和k′相的最高转变温度都并不恰好在等原子成份,而在于或小于49at.％Au。点阵间隔的量度表明:基本单胞平均点阵间隔同成份的关系是正偏离Vegard定律的连续曲线。在α和α′相区内,α值随Au含量而递增。在Au含量小于等
