Through a detailed study of the abundances and spatial-temporal distribution patterns of Te,Bi,As,Se,Cu,Pb,Zn,Au,and Ag in the rock types of different geological epochs in the Dashuigou independent tellurium deposit,and in combination with other research findings of previous researchers in this area,the authors conclude as follows:Abundances of the main ore-forming elements Te,Bi,As,Se,Au,and Ag are not high in the regional geological background,generally lower or close to their respective crustal Clark values,but almost all altered country rocks contain high levels of ore-forming *** indicates that the deposit’s ore-forming elements do not come from the country *** also indicates that the geological thermal events that cause alteration and mineralization originate from depths and may be related to mantle *** the distribution pattern of these ore-forming elements in the ore bodies’hanging wall and footwall,the metallogenic mechanism may be as follows:Mineralization is not achieved through lateral secretion in the horizontal or near horizontal direction,but rather through the upward movement and emplacement of deep ore-forming elements driven by geological processes such as mantle *** addition,the migration of deep ore-forming elements is not achieved through dispersed infiltration between overlying rock particles,but through non widespread concentrated penetrating *** type of channel is likely to be the expansion structures where faults from different directions intersect,or where linear faults intersect with circular structures.

琼东南盆地陵水气田位于中央峡谷上游,以浊积砂岩储层为主,受沉积和成岩作用共同影响,储层类型较为多样,表征难度较大。为了预测深水甜点区分布,依据峡谷形态和埋深规律,将峡谷上游区域沿浊流流向依次划分为调整段、顺直段和弯曲段;通过综合井筒中粒度、孔喉结构和填隙物类型对储层进行分类;基于岩石组构和物性参数间定量关系,分析对应沉积储层的沉积成因。研究认为,峡谷调整段以粗粒重力流沉积为主,随着颗粒间杂基含量降低,储层物性向下游逐渐变好;顺直段以细-粉砂浊流沉积为主,储层质量较为稳定,仅在局部因Ca^(2+)离子富集致使胶结作用增强;弯曲段以粉砂质浊流堆积为主,较细的沉积粒度致使储层质量向下游方向随着埋深的增加而逐渐变差。调整段沉积过程控制储层质量,顺直段-弯曲段成岩作用控制储层质量。

数字化时代，数据已成为社会运转的核心资产，而身份认证凭证是其中最关键且敏感的数据要素之一.传统的口令认证方法需在服务器存储账号、口令等凭证信息，面临严重的数据泄露隐患.基于公钥密码体系的无口令认证技术通过公私钥对替代传统口令，用户利用私钥计算认证信息的签名而实现认证，服务器仅存储公钥等公开信息，从而解决了服务器泄露私钥信息的问题.然而，现有无口令认证系统存在多平台认证不互通、在线认证延迟高、设备丢失私钥难恢复等痛点，且系统的透明度和审计能力有待提高.为解决这些问题，提出一种基于区块链的多平台兼容的高效无口令身份认证方案.将FIDO2无口令认证技术与区块链技术相结合，允许用户生成并上传多个账户公钥至区块链网络，供服务方公开验证，同时通过账户线下预注册、签名预计算、链上数据同步等优化手段，实现了可互通、低开销、大规模用户适用的身份认证.还设计了加密备份机制，即使用户设备遗失，也可利用保存的加密密钥恢复备份数据.此外，利用区块链提供不可篡改的数据存证，所有参与方均可查询认证授权状态，提高了系统透明度.最后，全面论述和评估了方案的安全性与系统性能，理论分析和实验结果表明，提出方案较同类型方案降低了89.09%的在线计算开销和85.57%的通信开销，且在高负载测试条件下仍能够保持低延迟的认证响应.

高碘、高砷地下水作为原生劣质地下水,具有区域性、伴生性和相似富集机理等特点.奎屯河流域是中国典型原生高砷水分布区,本研究基于奎屯河下游区域39组地下水水样,通过分析地下水水化学特征、赋存环境和水文地球化学过程,明确了该地区地下水中碘的分布特征与碘富集影响因素.结果表明:研究区地下水赋存环境为还原性弱碱性,I-浓度范围为13.96~574.85μg·L^(-1)(平均值为111.79μg·L^(-1)),38.46%的地下水为高碘地下水(ρ>100μg·L^(-1)),87.18%的地下水处于高砷环境(ρ>10μg·L^(-1)).地下水以低碘高砷地下水(53.85%)为主,其次为高碘高砷地下水(33.33%)、低碘低砷地下水(7.69%)、高碘低砷地下水(5.13%).地下水I^(-)浓度整体由南向北逐渐升高,高碘地区主要集中分布在研究区北部(126团、127团场、128团北侧靠近北山山前冲洪积砾土平原一带),占比为32.26%,适碘地区分布在研究区中部(128团场东部与南侧、127团和下游奎屯河南部),占比为38.40%,碘缺乏区域主要分布在研究区南部123团和129团,占比为29.33%.研究区地下水中铁氧化物还原性溶解和HCO_(3)^(-)与I^(-)的竞争吸附作用是影响地下水碘富集的主要因素,同时地下水中弱碱性还原环境、深厚的沉积层和滞缓的径流条件为碘的富集提供了有利的赋存环境和水文地质条件.
