Paisagem é uma paisagem é uma paisagem é uma paisagem
, 2013 O presente artigo pretende identificar uma certa ideia de paisagem num ponto específico da obra de João Jacinto, ponto esse onde a presença da paisagem será, porventura, menos evidente. Pelo caminho, tecemos algumas considerações sobre as possibilidades da pintura contemporânea, a relação desta com a imagem digital e com a sua rica tradição.

, 2004 以活性嫩黄K 4G模拟废水为处理对象 ,采用软锰矿与电化学协同法 ,分别在不同软锰矿加入量、电流密度、pH值、电解时间、染料初始浓度条件下进行电解实验 ,考察了各种因素对脱色率的影响。结果表明 ,增加软锰矿的用量、增大电流密度、降低pH值、延长电解时间都能提高脱色率 ,染料初始浓度对脱色率影响不显著。溶液中溶解态锰的浓度的变化表明 ,Mn(II)在处理过程中表现出催化作用 ...

, 2006 以废碱锰电池为试验材料，在小型管式炉中进行焙烧实验．借鉴燃煤中汞的形态研究分析方法（Ontario-Hydro分析法）研究了废碱锰电池焙烧过程中汞的形态及其分布．结果表明，汞脱除率达100％，尾气中总汞浓度为186．41～194．86mg·m^-3，Hg^0占气态汞总量的82．88％～86．64％，Hg^占6．02％～6．29％．研究结果说明在本试验条件下，废碱锰电池中的汞在焙烧＋过程中绝大部分以单质形式进入尾气，实际生产中可直接将尾气通过强制冷却，使汞冷凝 ...

, 2012 针对我国北方地区相当储量的低品位复杂软锰矿(MnO_2),采用微生物方法来浸锰。文中主要进行了硫化锰矿的生物浸出及氧化锰矿的强化生物浸出实验研究。结果显示,与无菌浸出实验结果相比,硫化锰矿的生物浸出过程速度快,浸出率高,经过6～7 d锰的浸出率已超过90%;添加硫化锰、黄铁矿以及硫酸亚铁对氧化锰矿的生物浸出过程都有很好的强化效果,添加硫化锰时,锰的浸出率在24 h时就超过了90%,而添加黄铁矿及硫酸亚铁则在第8 d时锰的浸出率达到97%以上。综合经济成本考虑 ...
