新时代全面深化改革具有深厚的历史逻辑、丰富的理论逻辑和鲜明的现实逻辑。从历史逻辑看,全面深化改革始于党的十一届三中全会,提出于党的十八届三中全会,成熟于党的二十届三中全会。从理论逻辑看,全面深化改革概念历经从改革与开放到改革开放,从全面改革到深化改革,再从全面改革、深化改革到全面深化改革的演化,全面深化改革以马克思主义、党的领导、中国特色社会主义、习近平新时代中国特色社会主义思想等为理论支撑。从现实逻辑看,新时代全面深化改革不仅体现了中国特色社会主义进入新时代改革的重要性与必要性,而且全面深化改革是应对中国改革面临的诸多挑战和机遇的时代选择,要将以人民为中心、坚持党的领导、推进国家治理体系和治理能力现代化、坚持社会主义制度、构建高水平社会主义市场经济体制、因地制宜发展新质生产力等作为新时代全面深化改革的现实抓手与工作重心。

摘要：本文建立了电感耦合等离子体质谱同时测定出口蔬菜中Mg、Ti、V、Cr、Mn、Fe、Ni、Cu、Zn、As、Se、Cd、Tb、Hg和Pb共15种无机元素的分析方法。样品在硝酸过氧化氢体系中经微波消解后直接上样分析，采用氦气碰撞模式消除了多原子离子质谱干扰，以Sc、Rh、In、Ir作为内标元素校正了质谱分析中基体效应并补偿了信号漂移。结果表明：测定质量浓度在0～50mg·kg^-1。范围内，各元素呈现良好的线性关系，r≥0．9995；检出限为0．003-37．21μg·kg^-1。选择国家标准物质豆角（GBW10021）、芹菜（GBW10048）和大葱（GBW10049）验证方法的可靠性，待测元素测定结果均在标准值允许范围内，日间相对标准偏差（n=6）在1．4％-19．4％之间。应用该方法测定了连云港蔬菜基地10种出口蔬菜，结果发现As、Cd、Ph、Cr、Hg含量均符合国内外相关标准中的限量要求。样品的测定结果为掌握连云港出口蔬菜中各种元素的含量水平，指导基地蔬菜的种植与出口提供了理论依据。

研究大断面管幕箱涵顶进全过程对土体变形和周围环境的影响,对于事前预测变形并控制施工扰动影响具有重要意义。基于Mindlin解答、修正Sagaseta公式等经典理论解答,分别考虑由正面推进力、摩擦力和土体损失等因素引起的地表变形,提出考虑三者共同作用下的大断面管幕箱涵顶进引起的地表变形计算方法。建立管幕箱涵顶进作用下土体受力模型,采用Mindlin解答分别给出正面推进力和摩擦力引起的土体变形计算公式;基于当层法原理提出由土体损失引起的横向地表沉降计算公式。根据各影响因素的相对独立性,将各因素引起的土体变形量叠加,从而得到一种适用于大断面管幕箱涵顶进施工,可综合考虑多种施工因素和土体三维变形的理论解答公式。通过工程实例验证公式的合理性,研究成果可为实际施工变形预测提供参考。
