用小波幅周期伏安测量法,分析浸入pH值为9.2的无黄药和含黄药硼酸盐溶液中的铜的氧化表面研究电化学位对铜和黄铜矿颗粒可浮性的影响。研究表明,黄原酸铜类物质的生成,不仅与铜和黄药离子之间的直接反应有关,而且也与黄药离子和与黄铜矿之间的直接反应有关。由资料得知,导致铜和黄铜矿颗粒疏水的物质是黄原酸铜类物质和双黄药。在微量浮选-电化学槽和丹佛型电化学槽中进行的浮选试验证明,当铜和黄铜矿表面上存在这两种物质时,可获得最大的可浮性。为了分析产生疏水性物质的稳定性,进行了电位降的测量。

We investigate if any testing should be *** All consecutive patients between january 2006 and December 2008 undergoing implantable cardioverterdefibrillator(ICD) implantation/replacement(a total of 634 patients) were included in the retrospective *** Sixteen patients(2.5%) were not tested(9 with LA/LVthrombus, 7 due to operator's decision). Analyzed were 618 patients [76% men, 66.4 + 11 years, 24% secondary prevention(SP), 46% with left ventricular ejection fraction(LVEF) ronary artery disease(CAD)] undergoing defibrillation safety testing(SMT) with an energy of 21 + 2.3 j. In 22/618 patients(3.6%) induced ventricular fibrillation(VF) could not be terminated with maximum energy of the ICD. Six of those(27%) had successful SMT after system modification or shock lead repositioning, 14 patients(64%) received a subcutaneous electrode array. Younger age(P = 0.0003), non-CAD(P = 0.007) and VF as index event for SP(P = 0.05) were associated with a higher incidence of ineffective SMT. LVEF revascularisation in patients with CAD had no impact on *** Defibrillation testing is well-tolerated. An ineffective SMT occurred in 4% and two third of those needed implantation of a subcutaneous electrode array to passa SMT > 10 j.
