Enrichment by air classification of indium components from In-containing scrap powders scraped by sand-blasting chamber shields of sputter coatersSungkyu Lee1,2,Soo-Bok Jeong3,Hang-Chul Jung4,Hyun... sieving and air-classification. Sieving was performed first as a feasibility test, and enrichment of indium com-ponent was possible up to 19 wt.% with a mesh size of 635. With this experimental basis......
Effects of deoxidizing degree on the pitting corrosion behavior of carbon and manganese steelsGuo-liang Cao, Guo-min Li, Shan Chen, Wan-shun Chang, and Xue-qun Chen College of Sciences, Naval... to long strip-like with increasing deoxidizing degree. Under the same conditions, the lower the deoxidizing degree gets, the lower the pitting initiation susceptibility becomes, and the stronger......

Influence of Elevated Curing Temperature on the Properties of Cement Paste and Concrete at the Same Hydration Degree王强,SHI Mengxiao,WANG DengquanDepartment of Civil Engineering, Tsinghua University摘... at these three temperatures were measured to determine the hydration degree of cement. Tests were carried out to compare the pore structure and strength of cement paste, as well as the strength and permeability......
and breakage of emulsion liquid membrane decline and the extraction efficiency is 99.4%. Key words: double emulsion; chromium; separation; enrichment ......
A New Two-staged Model to Predict Corrosion Degree of Steel Bars in Cracked Concrete Area王青1,2,3,WEI Jun1,3,LIU Xiaochun1,3,DONG Rongzhen1,31. School of Civil Engineering, Central South University2... of the proposed model. The model was applied to Chinese Railway Track System(CRTS)Ⅱ ballastless track slab with transverse dummy joints, from which satisfactory results of corrosion degree of steel bars were......
three-stage decarburization theory, the concept of mixing degree was put forward, which was used to indicate the effect of oxygen jet on decarburization. Furthermore, a more practical process model......
