Armed with this information and further analyses, Rumble, lead author Bekker, and colleagues propose the following scenario today in Science . Early in Earth's history, volcanic eruptions spewed massive amounts of sulfur dioxide into the atmosphere, where UV sunlight broke down the gas and created the odd sulfur isotope ratios. The sulfur descended with the rain and accumulated into sedimentary beds on the sea floor. Once there, superheated water from geothermal vents at various locations on the sea floor cooked the sulfur into sulfide. Finally, nickel-bearing magma welled up from Earth's mantle, combining with the sulfide to form nickel sulfide and encasing the compound inside volcanic rock called komatiite.

凭借这份资料和进一步的分析，朗布尔、研究论文的第一作者贝克及同事们今天在《科学》杂志上提出了如下的推测：在地球早期的历史上，火山爆发将大量的二氧化硫气体喷射到空中，太阳的紫外线将其分解，产生了奇特的硫同位素比值，这种硫随雨降下，积存于海底沉积层中；一旦到达海底，海底各处的地热出口所产生的温度过高的水把硫加热成硫化物；最终含有镍的岩浆从地幔中涌出，跟硫化物结合形成硫化镍，并将硫化镍包裹在一种叫做"科马提岩"的火山岩中。

In addition, many small businesses there is no perfect environmental protection facilities, high levels of lead smelting process steam, lead dust, sulfur dioxide and other harmful substances into the atmosphere, not only the job-site labor conditions also cause serious environmental pollution.

此外，许多小型企业没有完善环保设施，铅冶炼过程中的蒸汽高，到大气中铅尘，二氧化硫和其他有害物质，不仅是施工现场劳动条件，同样会造成严重的环境污染。

Researchers believe that this part of the male long-term high concentration of nitric oxide, a sulfur dioxide, carbon monoxide and lead the work environment, motor vehicle exhaust, and nitric oxide, lead, most likely to damage sperm quality.

研究人员认为，这部分男性长期在高浓度的一氧化氮、一氧化硫、一氧化碳和铅等汽车废气环境中工作，而一氧化氮、铅等，最容易破坏精子质量。

However, as well known, during traditional fire metallurgy of lead and production of lead/acid battery, there are emissions of lead vapor, sulfur dioxide and leady dust, which is harmful to the health of operators and brings about atmosphere pollution.

因此，应该研究和实现铅酸蓄电池的清洁生产。

Flow injection fluorometry for the determination of carbamazepine in pharmaceuticals and plasmaA simple, sensitive and specific spectrofluorimetric method has been developed for the determination of CBZ. The method was based on lead dioxide solid-phase reactor flow injection on-line oxidizing CBZ into fluorescent product in medium of phosphoric acid. The product has green-yellow fluorescence at excitation wavelength of 355 nm and emission wavelength of 478 nm, and the fluorescence intensity could be enhanced in the presence of acetone. The reaction conditions and experimental conditions were studied and optimized.

二、流动注射在线氧化荧光法测定卡马西平的研究利用卡马西平自身无荧光，经过氧化后可转变为在最大激发波长为355nm，最大发射波长为478nm的强荧光物质，而且丙酮对该荧光体系有增敏作用的现象，应用流动注射体系建立了以醋酸纤维素固定化的二氧化铅作为固相反应器、在磷酸介质中在线氧化荧光法测定卡马西平的新方法。

Experts believe the project with the traditional lead-smelting technology, has the following characteristics: First, the smelting process to adopt internationally advanced level of oxygen blowing at the end of smelting - to restore the blast furnace method, the use of lead refining electrolysis ; Second, the use of sulfur dioxide gas double-absorption acid technology, the production of domestic water use of recycled water sewage treatment process; Third, the use of waste heat for power generation, waste to make full use of energy reduces energy consumption; Fourth, the high level of automation, low power consumption , Investment, raw materials adaptable, comprehensive recovery rate of high-quality products.

专家认为，该项目与传统炼铅工艺技术相比，具有以下特点：一是冶炼工艺采用具有国际先进水平的氧气底吹熔炼-鼓风炉还原法，铅精炼采用电解法；二是二氧化硫烟气采用两转两吸制酸工艺，生产生活用水采用循环水污水处理工艺；三是利用余热发电，充分利用废弃能源降低了能耗；四是自动化水平高、能耗低、投资省、对原材料适应性强、综合回收率高、产品质量好。

For example, some primary and secondary copper smelting plant is still in use behind blast furnace process, sulfur dioxide utilization rate of only 65%; primary and secondary lead smelting enterprises, commonly used sintering pot lead smelting process, flue gas concentration is low, can not use the sulfur into the atmosphere each year up to 25 million tons.

例如，一些中小学炼铜厂仍处于落后高炉使用过程中，二氧化硫的只有65％的利用率，小学和中学铅冶炼企业，普遍使用的烧结锅炼铅工艺，烟气浓度低，可不使用到大气中的硫，每年达到25万吨。
