查询词典 copper coin

The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.

有机肥还具有提高土壤易氧化碳和松结态腐殖质含量，降低kos值，提高土壤HA、FA含量及其比值的作用，使土壤中有效态氮、磷、铁、锰、铜和锌含量处于中上等水平；长期秸秆还田除了不增加土壤全磷、有效氮和磷等外，对其他养分的作用效果与有机肥相似，但其肥效不如有机肥；长期氮磷化肥单施，土壤全氮和磷增加，有机质、铁、锰、铜和锌含量下降，易氧化碳、松结态腐殖质、HA和FA含量、kos和HA/FA值下降；长期不施肥土壤有机质、全氮等养分处于消耗状态。

That is less copper anion in the environment. PASP has the effect of corrosion inhibition in hydrochloric acid solution. In addition the potation of cathode summit current turned negative as increasing PASP concentration, and the potential of anode summit current turned positive, it can constrain the corrosion of copper. That is to say PASP is a mixed corrosion inhibitor and can constrain the corrosion of copper surface.

循环伏安测试结果表明： PASP的加入同时抑制了铜表面的阴阳极反应，使阴极峰和阳极峰电流都减弱，说明此环境中的铜离子的含量较少，PASP对铜在盐酸中有缓蚀作用；另外阴极峰电位随着PASP添加浓度的增大而依次变负，而阳极峰电位依次变正，抑制了铜的腐蚀，说明PASP是混合型缓蚀剂，有效地阻止了铜表面的腐蚀。

However, the copper alclad bus bar rabbet pushes aside presses technical the research is in the true sense by the aluminum festival copper, is saving the copper resources the aspect to have the very vital significance.

问题补充：这是我毕业论文的摘要，我也用过网上一些在线翻译的网站，可是感觉翻译得很差劲，希望大家能翻译得准确一点，我毕业就靠它了。非常感谢！谢谢大家的帮忙！

Trench is to recycled scrap copper, copper slag, and the circuit board for soldering copper components, direct remelt casting, in which the lead can not be separated, the content is very easy to exceed 3%.

地沟铜是把回收的废铜、铜渣，以及电路板上的锡焊铜元件，直接回炉铸造，其中的铅是无法分离出来的，含量很容易超过3%。

For this,experimental study was made on a new process of potential-controlled preferential flotation in a sequency of copper,lead and zinc,which used LP-01 as collector for copper mineral,DDTC as collector for lead mineral,copper sulfate and butyl...

为此，以LP-01为铜矿物的捕收剂、乙硫氮为铅矿物的捕收剂、硫酸铜和丁黄药为锌矿物的活化剂和捕收剂、石灰为矿浆电位调整剂，并在选铜、铅时配合使用铅矿物的组合抑制剂ZnSO4+YN，对该多金属复杂硫化矿进行了电位调控铜、铅、锌依次优先浮选新工艺试验研究，获得了含铜21.74%、铜回收率62.31%的铜精矿，含铅61.23%、铅回收率55.07%的铅精矿和含锌56.43%、锌回收率90.02%的锌精矿。

These revealed that high dose copper can destroy function of erythrocytic membrane and cause oxidative stress, which may be one of the mechanisms of goat erythrocytic haematolysis induced by high dose copper. 3 High copper caused the increase of osmotic fragility of erythrocyte and AGLT50 in acor glycerine solution.

高铜导致红细胞膜超氧化物歧化酶和谷胱甘肽过氧化物酶活性降低，氧化产物丙二醛含量增多，引起红细胞抗氧化功能降低，诱发氧化胁迫，使得红细胞处于氧化应激状态，这可能是高铜致羊红细胞溶破机制之一。

After the reckoning, the copper alclad power cable and under the copper conductor electric cable performance same condition compares: May save the copper material 78%, saves raw material cost above 20%, weight saving 40%.

The precision lapping technology to machine the copper substrate using semi-fixed abrasive plate was studied. The surface roughness and material removal rate as the evaluation of indicators, the influences of the different lapping parameters on the surface roughness and material removal rate were discussed and analyzed. Experimental results indicated that the copper substrate could be efficiently machined by semi-fixed abrasive plate of 800(superscript #) SiC abrasive, and the initial roughness Ra of a machined surface could be improved from 0.553μm to 0.28μm in 10min, produced an ideal rarely scratch surface. Then processed copper polished by diamonded grinding paste, it could be satisfied for the Ni-Pd-P alloy thin film growth.
