Based on the petrology,isotope geochemistry and fluid inclusions analysis,we established the evolutionary mode of the diagenetic fluid of dawsonite-bearing sandstone in the Jiyang ***-bearing sandstone is characterized by double injection of CO_(2)and oil-gas in the Jiyang Depression that have experienced a relatively complex diagenetic fluid evolution *** diagenetic sequence of secondary minerals involves secondary enlargement of quartz,kaolinite,first-stage calcite,dawsonite,second-stage calcite,ferrocalcite,dolomite and *** charging in the dawsonite-bearing sandstone occurred at around 2.6–0 *** CO_(2)charging event occurred during Dongying tectonism,forming the Pingfangwang CO_(2)gas reservoir,which provided an abundant carbon source for dawsonite *** and oxygen isotopic compositions of dawsonite demonstrate that CO_(2)forming the dawsonite was of an inorganic origin derived from the mantle,and that water mediating the proc-ess during dawsonite precipitation was sequestered brine with a fluid temperature of 82℃.The evolutionary sequence of the diagenetic fluid in the dawsonite-bearing sandstone was:alkaline syngenetic fluids,weak alkaline fluids during organic acid forma-tion,acidic fluids in the early stage of CO_(2)injection,alkaline fluids in the late stage of CO_(2)injection,and weak alkaline fluids during oil and gas *** mode indicates an increase in-HCO_(3)because of the CO_(2)injection,and the loss of Ca^(2+)and Mg^(2+)due to the precipitation of carbonate ***,the evolutionary mode of diagenetic fluids is in good agreement with high HCO_(3)^(-),low Ca^(2+)and low Mg^(2+)composition of the present formation water in the dawsonite-bearing sandstone.

Basin-type insulator often has small cracks due to stress *** current method cannot accurately reflect the stress condition of the insulator to find the stress concentration *** solve these problems,a method for detecting two-dimensional plane stress(δ_(1) andδ_(2))within different depth ranges in a basin-type insulator is proposed based on critically refracted longitudinal(LCR)***,the acoustoelastic equation characterising the relationship between the variation of LCR wave propagation time and the plane stress was ***,the propagation characteristics of LCR wave in epoxy resin samples were ***,the stress distribution within different depth ranges of the insulator subjected to hydraulic load was measured using the proposed method,including direction(θ),δ_(1) andδ_(2).The results show that the magnitude of the stress alone cannot accurately characterise the stress *** with equal distances to the centre have similar stress magnitudes,but their directions are not the *** increasing depth,θremains essentially unchanged at the same location,whileδ1 andδ2 decrease,and the rate of decrease varies at different *** the measured and simulated data,the results showed that they were in good agreement,and the maximum errors of stress value andθwere 0.69 MPa and 2.97°,respectively,which confirmed the feasibility and accuracy of the stress detection in the proposed method.

本文从STS理论视角出发,将可穿戴技术界定为一种“附身的技术”。在新闻实践范畴,可穿戴技术颠覆了传统意义上将技术视为生产工具的逻辑,令技术使用者本身成为新闻报道的一部分。本文据此提出“可穿戴新闻”概念,并尝试对其特征进行界定:提供可实时采集和传输的个体“生命数据”,并将其整合为一种整体的社会技术想象;革新新闻叙事话语,创造第一人称的“生活叙事”空间影像,使新闻内容可以是他人生命与生活体验的数字复制品。新闻因此在更显著意义上成为一种“共情感知体验”的实践。文章进一步提出,可穿戴新闻令接受者得以“附身”他人的情感体验,这种“他者化”转型具有促进跨越文化的共鸣和理解、构建人类情感共同体的潜能。随着可穿戴技术在新闻实践中的普及,新闻日益成为连接个体生活、共享生命经验的桥梁,这将创造一种内在关系更为紧密的“人-机-社会”互动机制。
