当今社会的工业化规模制造中,无损检测技术已被广泛应用于航空、航海、航天、核电等领域用管的质量检验中,对确保产品质量起到了卓有成效的作用.然而,无损检测发展至今,已不仅仅是通常的"无损检查/无损检测/无损探伤"的含义了,其已发展到通过对记录的指示进行解释后的一种审查,以确定这些指示是否满足特定的验收准则阶段,即无损检测已向"无损评价"方向发展,为产品的质量控制提供有力的支持.
The purification effects of 7-(4-ethyl-1-methyloctyl)-8-hydroxyquinoline (kelexl00) extraction agent were researched in the CuC1-NH3-NH4C1 system, which using the scrap copper ammoniacal etchant as ra
Recently, focusing on the design of integrated recovery of vanadium and associated chromium (2400 mg/Kg vanadium slag) from vanadium slag simultaneously (Chaurand et al., 2006), a novel vanadium slag
The process and mechanism of preparation of highly pure manganese sulfate from roasted product of interactive roast of bismuthinite and pyrolusite is presented.The process includes the three main step
A novel process of direct solvent extraction of nickel from sulfuric acid leach solutions of laterite using a new extractant HBLll0 was introduced.The basic performance of new organic system was inves
Ti-doped Li3V2(PO4)3/C cathode materials were synthesized by a novel sol-gel method with titanate coupling agent TC-Wt as a chelating agent, titanium and carbon sources.The effects of synthesis temper
5LiFePO4·Li3V2(PO4)3/℃ composites had been obtained by sol-gel method, using LiOH·H2O,Fe(NO3)3, NH4VO3, NH4H2PO4 and citric acid as raw materials.Structure and morphology of the obtained materials hav
Several P507 based novel extraction systems were reported ever since P507 had been confronted with low selectivity and incomplete stripping efficiency for heavy rare earth elements.This article was ai
Calixarenes, as the third macrocyclic compounds, have been known for their excellent coordination and extraction abilities toward metal ions (Ohto et al., 2011).Organophosphorus compounds have also be
Leptospirillum ferriphilum belongs to Leptospirillum genus, which has been found to be the most representative moderate thermophiles in bioleaching of sulfide minerals and be dominant iron-oxidation b
