查询词典 lead-coated

Through screening and comprehensive analysis of childhood lead poisoning caused by automobile exhaust pollution is the main factor, as automobile exhaust lead dust accumulation in more than one meter above the ground, and that is exactly the children's activities with the breathing zone of pollution caused by it has become one of the major causes of childhood lead poisoning.

通过筛查和综合分析，造成儿童铅中毒的因素主要是汽车尾气污染，由于汽车尾气铅尘多积聚在地面以上1米的范围，这正好是儿童的活动与呼吸带，它所引起的污染已成为儿童铅中毒的主要原因之一。

Jinan Mingquan Writing Instrument Co.,Ltd is a professional corporation in producing pencils lead and pencils since it was built in 1989.Sticking to the principle of "existing by quality,developing by innovation",we are making concerted effort,so that the scope of the enterprise is becoming more broader.And now,it has three branchers: graphite lead plant,color lead plant,and pencil plant.

Determination of silver in lead ore by AAS;2. The ore is lead mine of partial oxidation,the lead ore consists chiefly of galena and cerusite.

所处理矿石为半氧化铅矿石，矿石中铅以方铅矿和白铅矿形式产出，铅的氧化物主要为白铅矿，分布率达39%。

When the concentration of lead was very high, the most of lead linked weekly with the cell wall of root and was easy to dissolve into acidic solution. But about 50μg Pb/g cell wall was very hardly desorbed, it might be entered into the cell wall. This phenomena showed that the complete desorption of lead will be very difficult.

铅浓度高的细胞壁，其相当大部分的铅与细胞壁的结合力并不大，因此在用强酸处理时，就比较容易地溶解下来，但是大概有50微克／克细胞壁的铅，它们的结合牢度大，或者深入到了细胞壁的组织中，因此很难解吸下来，这将会对铅的彻底去除带来困难。

The main technological innovation is as follows: Adopting collector Bp was of high-effect to float copper; using no-toxic and combinatorial depressants to depress lead, the experiment was carried out effectively for separation of copper-lead; Adopting processing of copper middle to concentrate a cyclone classificating and a mill regrinding, it solved the vicious cycle of the lead and was of low dissociation.

其主要技术创新点有：采用高效捕收剂BP实现铜铅优先浮选；采用高效无毒组合抑制剂实现铜铅的有效分离；采用铜中矿集中旋流器分级再磨处理解决了铅的恶性循环和单体解离度低，有效地解决了铜铅分离的技术难题。

Under the condition of organic chlorine content 0.25-0.53% of the input refuse and the furnace temperature range of 939-1,033℃, rise with furnace temperature, the proportion of lead transferred into gaseous is increased, and the lead content of fly ash and reaction ash increases obviously. It can be expressed as y1 =11.051x－9824.9 and y2 =26.729x－23680, where x is the furnace temperature, y1 and y2 are the content of lead in fly ash and reaction ash.

基於进料综合垃圾有机氯含量0.250.53％之条件下，在9391，033℃之炉温范围内，随著炉温升高，重金属铅由固相转移至气相的比例增加，飞灰及反应生成灰之铅全含量皆有明显上升之趋势，可以回归式表示为y1 = 11.051x – 9824.9以及y2 = 26.729x – 23680，其中x为炉温，y1、y2则分别为飞灰及反应生成灰之铅全含量。

Industrial pollution can come from lead mining, smelting, rubber production, dye, printing, ceramics, lead glass, solder, cables and lead pipes and other industrial waste water and refuse.

铅的工业污染来自矿山开采、冶炼、橡胶生产、染料、印刷、陶瓷、铅玻璃、焊锡、电缆及铅管等工业产生的废水和废弃物。
