方法示波极谱法测定尿铅，血铅；汇总尿铅、血铅测定的数据资料并进行分析。

Methods 112 blood samples of occupationally lead-exposed workers were selected from a puddling factory in the suburb of Chengdu. An assay based on the polymerase chain reaction-restriction fragment length polymorphism technique of restriction enzyme Bsm Ⅰ was used to detect at the same time.

整群抽取成都市郊区某炼铁厂接铅作业人员112人，抽取其静脉血进行血铅、血清钙和基因多态性测定，按基因型测定结果分组分别比较其血铅、血清钙的差异，并进行血铅和血清钙的相关性分析。

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。

Direct separation of lead and antimony from jamesonite by oxidizing volatilization roasting, with addition of one kind of catalyst; in addition, it discusses separately the factors that affect lead and antimony separation results under such process.

本试验研究了一种新工艺，通过加入一种催化剂，对脆硫铅锑矿进行氧化挥发焙烧，实现铅锑的一步分离；同时，对该工艺下影响脆硫铅锑矿铅锑分离效果的因素也分别进行了讨论。

Methods Male NIH rats were treated with water containing 0.1% lead acetatic trihydrate for establishing an experimental lead poisoning rats model.

方法取小鼠，饮水给予。1%三水合乙酸铅水溶液建立小鼠预防性铅目的评价QQL排铅口服液的促进排铅功能。

A systematic study on S and/or Pb isotopic compositions of the copper-bearing porphyries, ore minerals and andesite of the deposit shows that S isotopic compositions of ore minerals are similar to those of porphyries.

矿石矿物（208Pb/204Pb=37.917~38.230，平均值38.075；207Pb/204Pb=15.528~15.614，平均值15.571；206Pb/204Pb=17.929~18.082，平均值17.981）与矿化斑岩(208Pb/204Pb=37.832、37.883，207Pb/204Pb=15.529、15.538，206Pb/204Pb=17.906、17.910)以及安山岩(208Pb/204Pb=37.816~37.884，207Pb/204Pb=15.549~15.562，206Pb/204Pb=17.845~17.919)的初始铅组成基本一致，变化范围较小，表明三者具有相同的来源；在铅构造模式图上，所有样品铅同位素均位于造山带演化线上或附近，在铅同位素源区判别图中，均落入造山带和下地壳区域，这表明Pb主要来源于壳幔混合。

The resuts revealed that lead has no effect on the mortality but can affect the contractile of cardiac cell and that zinc and seleni- um can protect the cell against abnormal contractile by lead.

同时还观察了锌、硒对铅致心肌细胞损伤的影响，以期为在驱铅治疗的同时，针对铅对心肌损害的对症治疗及从饮食角度干预中低浓度铅毒性提供理论依据。

May 15. I carry'd two Hatchets to try if I could not cut a Piece off of the Roll of Lead, by placing the Edge of one Hatchet, and driving it with the other; but as it lay about a Foot and a half in the Water, I could not make any Blow to drive the Hatchet.

五月十五日我带了两把小斧上船，想用一把小斧的斧口放在那卷铅皮上，再用另一把去敲，试试能不能截一块铅皮下来。但因为铅皮在水下有一英尺半深，根本无法敲到放在铅皮上的手斧。

The rocks of early Proterozoic and Archaean contain the lower potassium feldspar and lead number in potassium feldspar is lower than 10% of lead in the whole rocks.

中文摘要：在中-酸性岩浆岩、碱性岩浆岩、片麻岩及混合岩等岩石类型中，钾长石是含铅最高的造岩矿物，其铅含量是全岩铅含量的2～10倍，云母类矿物铅含量的3～16倍，石英铅含量的6～32倍。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
