Deformation measurement is crucial for forecasting landslide hazards of natural and engineered slopes.Ground-based differential interferometric radar (GB-DInRad) uses phase differential interferometric technology for surface deforma-tion measurements and offers the advantages of all-day,all-weather,and noncontact measurements.However,this tech-nique can only measure one-dimensional (1D) deformations along a radar-target line of sight (LOS).For conventional scanning GB-DInRad,its measurement speed is limited by the mechanical movement of antennas.Complicated envi-ronmental disturbances also severely affect the measurement accuracy.

基层党组织是党的组织体系中最重要、最基础的力量，是党最重要的执政基础。本文以万柏林区基层党建为例，以创建“全国文明城市”为抓手，通过分析万柏林区基层党建的基本情况，阐述了在创城工作中如何更好地发挥基层党组织的战斗堡垒作用和党员的先锋模范作用，并通过调研和相关责任人座谈，深入了解情况，对存在的问题加以分析、提出建议，为创城工作乃至今后的各项工作畅通思路，筑好战斗堡垒。
正所谓“绿水青山就是金山银山”，党的十九大以来，以效率、和谐、持续为发展目的的绿色经济理念受到社会各界的高度关注。绿色经济理念是对传统的以环境破坏、资源消耗为代价的经济模式的一种革新，符合可持续发展战略理念，对于发展与生态的和谐具有重要驱动作用。基于此，本文将简要分析环境与价值观念，介绍绿色经济的内涵，并结合时代发展需求阐述绿色经济的具体发展路径。
In this paper,a novel directional modulation with distributed receiver selection (DM-DRS)scheme is proposed for secure wireless communications.In DM-DRS,a particular subset of receivers is ac-tivated and part of the information bits are modulated by the i
伴随着我国市场经济改革的不断深入，越来越多的国有企业开始引入或自主构建现代经营管理模式，而政工工作作为国有企业管理的一项重要组成部分，其工作模式的调整与创新，也必须与现代企业经营管理模式相符合。本文主要探讨了新时期国企政工工作的职能定位及模式创新。

选取2010-2019年中国165家商业银行年度数据对贷款竞争对银行风险承担的影响及其作用机制进行实证分析,研究表明:贷款竞争对银行风险承担具有抑制作用,相对于国有银行与城农商行,贷款竞争对股份制银行风险承担的抑制力度更大;存贷利差在贷款竞争与银行风险承担的关系中承担着中介作用,贷款竞争通过降低存贷利差渠道来降低银行风险承担,“贷款竞争-存贷利差-银行风险承担”的传导渠道有效;跨境资本流动对两者关系具有负向调节作用,跨境资本流动规模提高会减弱贷款竞争对银行风险承担的抑制作用,跨境资本流动的负向调节作用对城

Recently,remarkable progress of deep reinforcement learn-ing (DRL) with regard to robot skill learning has been wit-nessed [1].However,manipulation skill learning on multi-step complicated tasks with DRL still poses great challenges owing to its higher ex
随着国家综合实力的提升，人们的生活质量也越来越高，大量人口涌入城市，有效促进了我国城市化进程的深入。但随之而来的问题就是，大量人口流动导致工作岗位缺乏的就业问题越发突出，需要通过技能培训促进就业，尤其是对于基层地区来说，需要通过专业的技能培训活动实现就业脱贫。作为行政单位，人社局的主要工作就是完善劳动收入分配制度，充分发挥人力资源优势，加快建立统一规范的人力资源市场，促进人力资源合理流动、有效配置。
