The SiCp (20 %) reinforced cobalt-based alloy composite coatings deposited by laser cladding on IF steel were introduced. The microstructure across the whole se
Image processing technique was employed to analyze pitting corrosion morphologies of 304 stainless steel exposed to FeCl3 environments. BP neural network models
The effect of RE-modifier on the microstructure and mechanical properties of high carbon-medium manganese steel has been investigated in present work. The resul
ERH end-quenching method was us ed to determine the hardenability of four kinds hot-forging die steels with dee p-hardening and hence the order of their hardena
晶粒白云岩是川西坳陷雷口坡组四段上亚段最好的储集岩,其厚度大、分布广且孔隙度、渗透率高。区内晶粒白云岩成岩作用类型多样,主要有白云石化作用、压实作用、溶蚀作用、压
1 前言用电子计算机进行“透镜自动设计的方法”,作为光学设计工作的工具来说,现在感到是完全成熟了。这种自动设计方法,自从电子计算机出现以来,不仅仅作为单纯的计算工具,而且在设计过程中,可以频繁地观察计算机,所以也可以说由于积极灵活运用使重复工作得以自动化,结果,从设计周期的缩短、光学系统精度的提高、复杂化、多样化以及紧凑
The development trend of coated and plated technology for continuous strip steels, which include hot dip plating, electroplating, organic coating and vacuum pla
如果单纯从供应链系统解决方案所看到的可视化、数据管理、交易和执行管理、业务分析、持续改进的实时计划和实施等功能，OneNetwork与其它供应链管理供应商的差别不大，但是，OneN
The influence of rare earth (RE) content on mechanical properties and abrasion resistance of low chromium semi-steel was studied by means of metallographic exam
