Methods Male NIH rats were treated with water containing 0.1% lead acetatic trihydrate for establishing an experimental lead poisoning rats model. QQL health liquid was administrated to rats through every day. Thirty days later, rats were killed, then the concentration of lead in blood, liver and femur were determined.

The loss in Peruvian lead mine output from the strike action is likely to have been minimal, with production unaffected at Milpo?s mines, El Porvenir (20,000t/y lead-in-concentrate) and Cerro Lindo (ramping up to 10,000t/y) and Volcan?s Cerro de Pasco mine (40-50,000t/y), but temporarily idling output at Glencore?s Yauliyacu operations (~35,000t/y combined production) and at Volcan?s Andaychagua mine (5,000t/y). Last year, Peru produced 329,000t of lead-in-concentrate, up5% year-on-year.

罢工对秘鲁铅矿造成的损失较小，其中Milpo矿，El Porvenir矿（铅精矿年产能20，000吨），Cerro Lindo矿（年产能10，000吨）以及Volcan公司旗下Cerro de Pasco矿（年产能40－50，000吨）产量均未受影响，但Glencore公司旗下Yauliyacu矿（年产能约为35，000吨）以及Volcan公司旗下Andaychagua矿（年产能5，000吨）的部分产能暂时被闲置。

These rise the village outstanding people have the wish to lead the fellow villager to move toward together wealthily, because like this not can only promote them in rural society's status, can also continue for them to create the wealth to provide the safeguard; But they lead the wish which the fellow villager becomes rich together similarly also with the national development rural economy well-off peasant's desire to agree with; Simultaneously the farmer not only needs these outstanding people to speak on another's behalf for them, to reflect their desire and the request, also hoped that these outstanding people use their ability, the wealth, the relations, the experience and so on to lead itself to become rich.

这些崛起的乡村精英们有意愿带领乡邻一起走向富裕，因为这样不仅能提升他们在乡村社会的地位，也能为他们继续创造财富提供保障；而他们带动乡邻一起致富的意愿同样也与国家发展农村经济富裕农民的愿望相契合；同时农民不仅需要这些精英们为他们代言、反映他们的愿望和要求，也希望这些精英们利用他们的能力、财富、关系、见识等带领自己致富。

There is a big problem that too much sulphur is wasted in lead bullion pyro-refining process by adding sulphur directly in northwest metallurgy of lead and zinc factory. As to the problem, a new method to decopper from lead billion through changing sulphur to PbS is invented.

针对西北铅锌厂粗铅火法精炼过程中，直接加单质硫进行除铜而出现硫损过大的问题，对除铜工艺中硫的利用方式进行了研究，提出一种除铜新工艺，即利用硫化铅代替单质硫进行除铜。

Lead 1、soft blue-gray mineral; lead sulfide; a major source of lead

Chinese E moves net and PHPwind strong strong combination, roll out lead plane of PHPwind super forum, MYSQL column is found after the user of use PHPwind lead plane should enter fictitious lead plane to manage only, add a Mysql database that belongs to oneself, use directly already analytic good domain name visit, can receive the installation page of PHPwind.

中国E动网和PHPwind强强联合，推出PHPwind超级论坛主机，使用PHPwind主机的用户只要进入虚拟主机管理后找到MYSQL栏目，添加一个属于自己的mysql数据库，直接用已经解析好了的域名访问，即可得到PHPwind的安装页面。

Using this method, alignment between headstock and tailstock centers is not able to be adjusted, and is far from what would be considered "close tolerances." All leadscrews have 1/4-20 threads, with the cross slide and main lead screws being the appropriate left-hand lead, while the tailstock is a right-hand lead, so turning the handwheel always advances the slide away from the user.

使用这种方法，路线之间的 headstock和尾架中心，是无法加以调整，是远远没有到会被认为是&密切公差&的所有leadscrews有1/4-20线程，与两岸幻灯片和主要领导螺丝被适当的左莅带头作用，而尾架是一个右手边的铅，因此，把手始终进展幻灯片远离用户。

F In case of making use of evaporative cooling for copper ring down-lead and main lead-out line of stator coil, airproof test for both the lead-out line and connection tube is required.

f铜环引线和主引出线采用蒸发冷却方式时，引出线和连接管件的气密试验。

E In case of making use of evaporative cooling for copper ring down-lead and main lead-out line of stator coil, both the lead-out line and connection tube shall take hydraulic pressure and airproof test

e铜环引线和主引出线采用蒸发冷却方式时，引出线和连接管件均应进行水压和气密试验。

The; of down-lead of 200 A binary electric current that the design made intensity of central field magnetic induction be 3 T is opposite through the experiment of the thermal resistance of interior of the leakage heat of voltaic down-lead, heat exchanger and line of high temperature superconduction and cupreous matrix solder resistor undertook metrical, studied refrigeration engine trouble or the transient state temperature of down-lead of the electric current below power cut condition changes.

设计制作了中心场磁感应强度为3 T的200 A二元电流引线；通过实验对电流引线的漏热、换热器内部的热阻以及高温超导线和铜基体的焊接电阻进行了测量，并探究了制冷机故障或者停电状态下电流引线的瞬态温度变化。
