As a kind of function cladding material , amorphous alloy cladding possesses the fine electromagnetism and static electricity protective performance as well as the fine physical chemistry function 摘要非晶态合金镀层作为一种功能镀层具有优良的电磁、静电防护性能,以及优良的物理化学性能。
Using 304l wire as the cladding material , the experimental results proved that the relationship among welding bead width , welding current and speed could be expressed with a plane in an x - y - z coordinate 对采用304l不锈钢作为单一熔覆材料的成形试验研究表明:电流、成形速度与成形轨迹宽度的关系可以采用平面几何关系表示。
It may be easier to justify the cost of pv cladding materials for commercial buildings , and the occupancy pattern means that they are much better suited to the availability of the electrical power produced ( see case studies 3 . 3 , 3 . 4 , 3 . 5 and 4 . 2 ) 可能证实在商业建筑中采用pv铺盖材料的经济可行性是容易的,并且它的使用方式也证明了其更加适合生产电能(见案例分析3 . 3 , 3 . 4 , 3 . 5和4 . 2 ) 。
The development of pv cells is continuing , and there appears to be great potential for the use of modern cells , most recently as building - integrated cladding materials rather than stand - alone arrays , for example , as adaptations of rainscreens , roof tiles and windows Pv电池不断的得到发展,开始显示出替代现有电池的巨大潜能,最近其作为建筑覆盖层材料,同建筑物融合于一体要优于仅仅排列使用,例如将其做成改进的防雨层、瓦和窗户。
The ceramic - metal cladding material on the steel substrate is a new type of cladding material which has great development potential because of having functional dominances of both high hardness , excellent wear resistance of ceramics and high strength , toughness , good thermal conductivity of ceramics and high strength , toughness , good thermal conductivity of metal 制备出的金属陶瓷-钢覆层材料同时具有陶瓷材料硬度高、耐磨、耐腐蚀和金属钢强度高、韧性好、导热性好的性能优势,是一种很有发展潜力的高硬复合材料。
There are still many problems remain to be solved in these aspects , such as research on the cladding material , lateral resistant system and steel frame connections , etc . in this paper six 1 : 2 - scale steel frame specimens and eight full - scale steel frame connection specimens are tested on their behavior under cycle loading . there are five aspects as below on the problems of steel resident building researched : 1 a new lateral resistant system , which is steel frame with cavity sandwich wall infill , is put forward for the first time in this paper 本文针对钢结构住宅体系中亟待解决的若干问题,完成了六榀1 : 2钢框架模型试验和八个足尺比例的梁柱连接模型在低周往复荷载作用下的试验,进行了以下几个方面的深入研究: 1本文首次提出了一种新型的空腔复合填充墙钢框架抗侧力体系。
Crack generation in laser - clad coatings is the most difficult problem t o be solved before massive application of this technology . in order to seek out effective methods for eliminating or reducing crack generation , we carried out systemic experiments and mechanism analyses on the design of laser cladding materials , the exploration of laser cladding technique , the interaction between laser and materials , the microstructure and properties of the coatings 针对阻碍激光熔覆技术工业化推广应用进程的主要问题之一的熔覆层裂纹问题,为寻求该问题的有效解决方法,从熔覆材料体系的设计、熔覆工艺的探索和规范以及在工艺规范条件下激光与熔覆材料的相互作用关系、涂层组织和性能到工件表面的最后强化和改性效果,进行了系统实验研究和机理分析。
But many problem remain should be solved in these aspects , such as research on lateral resistant system , the cladding material and steel frame connections , etc . to the lateral resistant system , one of the imperative problems in the steel residential building , we expect to research a new earthquake resistance element with great stiffness in the usual day ( for the needing of safety and comfort in the place where is windy and earthquake occurred frequently ) ; low stiffness in strong motion earthquake ( for the flexibility of residential building in the strong motion earthquake ) and absorbing seismic energy 从技术角度讲,如何使钢结构适应住宅建筑的特点,满足住宅产业化发展的需要,还有许多问题有待进一步研究,如抗侧力体系、维护体系及其梁柱的节点问题等等。针对钢结构住宅中急需解决的抗侧力体系问题,本文研究了一种正常使用情况下刚度大(满足建筑物在风载及常遇地震下人们舒适性和安全感的要求) ,强震时刚度低(保证强震时建筑具有柔性的特点) ,而且可吸收地震能量的新型抗震单元。
