precipitation in the lead-zinc deposits in this area, which substantially affects our understanding of the temporal-spatial distribution law of ore-forming elements and deposit types to direct mineral... and Zn must be established. According to previous studies [25, 42], the ratio of Pb: Zn can be set as 1:2. Based on HAN et al [44], the ore-forming pressure in lead and zinc sulfide deposits is between......
reactions: cathodic reduction of Fe3+ to Fe2+ [28] and anodic oxidation of Fe2+ to Fe3+ [29]. Mn2+ ions are oxidized on an anode surface, forming protective layer of MnO2 [30]. In turn, aluminum......
constituents forming ash, especially at higher pyrolysis temperatures [39]. In addition, the pyrolysis of SS has no definite effect on the content of FC in biochar. The content of VOM in biochar is also......
under the curing stress [54]. Due to the curing stress, part of the micro-cracks will be closed in the ITZ. Meantime, the unhydrated cement particles tend to agglomerate, forming a flocculated......

Effect of natural aging on the tensile properties of the Al-Li alloys 8090, 8091... Society of China, 2004, 14(2): 321-324. [37] TSIVOULAS D, PRANGNELL P B. The effect of Mn and Zr dispersoid-forming additions on recrystallization resistance in Al-Cu-Li AA2198 sheet[J]. Acta......
frequently, many array elements cannot be set due to environmental conditions. One-dimensional azimuth estimation generally used the time delay method [19] and beam forming method [20], but this method......
of the Al 1100 alloy coated with a powder mixture of "Ni+14Al+ CuO+2NiO". The authors suggested a reaction between Al and Cu in the liquid state with Al3Ni2, forming Al7Cu4Ni during cooling by the reaction......
hydration reaction, as shown in Figure 7(b). The needle-like ettringite also aggregates into relatively large strips while forming minute needles. Furthermore, the C-S-H gel initially grew and partly......
