摘要：To provide scientific management basis for the garden planning, project construction, maintenance, social service, this paper prompted that the urban gardening administration sectors need to construct gardening information management system. On the basis of fully requirements analysis of gardening sectors, this paper discussed the key technology for system construction. It also proposed to flexibly and smartly build up the system by using the secondary development design environment and running environment based on data center integration development platform. This system greatly helps the daily management and plays very important role in improving urban ecological environment and investment environment.

摘要：近几年,不少语言学家开拓了研究广告用语的新途径,即从语用学的角度来分析广告用语,其中语用预设更是成为广告用语研究中的奇葩,受到了学者的重视。基于语用预设研究现状,本文将结合中国奥运会赞助企业电视广告用语实例,深入分析其中存在的语用预设及其令人折服的广告效果。同时,笔者还通过对奥运电视广告的分析,对广告语用预设分析提出自己的建议——增加"社会影响力"预设。

摘要：水下闸阀是水下生产系统的关键,其稳定性和安全性对油田安全至关重要。针对国内海洋天然气工业水下阀门技术瓶颈,本文提出一种新型水下闸阀方案,适用于深水环境。设计强调动作可靠性,基于液压执行机构,引入独立螺旋传动执行机构作为应急方案,确保液压故障时能迅速切换,保障闸阀持续运行。同时,深入分析和验证了闸阀的密封性能,确保高压环境下的密封性。开发的阀门控制系统采用西门子PLC和相关软件编写控制程序,实现精确控制。液压故障时,系统自动切换至螺旋传动执行机构,确保操作的连续性和可靠性。

摘要：Cyclic dinucleotides(CDNs) are known to activate stimulator of interferon genes(STING) and induce type I interferon responses, therefor possess great potentials to be of immunotherapeutic value for cancers and infectious diseases. However, the existence of different single nucleotide polymorphism(SNP) of human STING(hSTING) gene poses an obstacle to achieve broad-spectrum activation by CDNs. We reported here the design and synthesis of a total of 36 CDNs, representing all structural variations, that contain four bases(A, G, C, U) and two linkage directions(2′-5′-linked and 3′-5′-linked phosphodiester).Through systematic evaluation of IFN-β induction with a dual-luciferase reporter assay, we discovered that wild type hSTING and two isoforms(HAQ and AQ) showed strong response while hSTING-R232 H and R293 Q exhibited the relatively weak response to CDNs stimulation. For the first time, we found that the c[G(2′,5′)U(2′,5′)] showed excellent activity against all five hSTING variants even equivalent to the endogenous ligand c[G(2′,5′)A(3′,5′)]. Furthermore, we have also demonstrated that 3′-3′CDNs with two 3′-5′ phosphodiesters showed higher serum and hydrolase stability than 2′-2′ CDNs with two 2′-5′ phosphodiesters and 2′-3′ CDNs with one 2′-5′ and one 3′-5′ phosphodiester. It is very interesting to note that 2′-2′ CDNs has been found for the first time to show strong activity. These findings will stimulate our exploration for the new functional role of CDNs, and provide guidelines to design CDNs based hSTING targeted drugs.

摘要：In this study, two full-size concrete wails were tested and analyzed to demonstrate the effectiveness of a chemically reactive enamel （CRE） coating in improving their mechanical behavior under blast loading： one with CRE-coated rebar and the other with uncoated rebar. Each wall was subjected in sequence to four explosive loads with equivalent 2, 4, 6-trinitrotoluene （TNT） charge weights of 1.82, 4.54, 13.6, and 20.4 kg. A finite element model of each wall under a close-in blast load was developed and validated with pressure and strain measurements, and used to predict rebar stresses and concrete surface sWain distributions of the wall. The test results and visual inspections consistently indicated that, compared with the barrier wall with uncoated reinforcement, the wall with CRE-coated rebar has fewer concrete cracks on the front and back faces, more effective stress transfers from concrete to steel rebar, and stronger connections with its concrete base. The concrete surface strain distributions predicted by the model under various loading conditions are in good agreement with the crack patterns observed during the tests.

摘要：在富水软土地基工程中,选择合适的施工技术是确保工程稳定性和安全性的关键。SMW(Soil Mixing Wall)工法桩与预应力型钢组合支撑施工技术因其优越的止水性能和承载能力,成为解决此类地基问题的有效方案。详细探讨了该组合技术的应用,包括施工流程、设计参数、质量控制措施及应对挑战的策略。SMW工法桩通过将水泥浆与土体搅拌形成高强度连续墙体,提供优异的防渗性能和承载能力。预应力型钢支撑则通过施加预应力,增强支撑系统的刚度和抗变形能力。两者的结合有效提高了基坑支护系统的整体性能,确保施工的顺利进行和后期使用的安全性。
