Ore deposits of this region are assigned to Caledonian metallogenic series and Indosinian metallogenic series according to ore-bearing strata, granites related to ore deposits mineralization type and temporal-spatial distribution characteristics of ore deposits. The Caledonian series is further divided into three subseries, namely lead and zinc metallogenic subseries, lead, zinc and iron metallogenic subseries and lead, zinc, tungsten, tin and molybdenum metallogenic subseries.

本文根据所发现的25个矿床的赋矿地层、与成矿有关的花岗岩、矿化类型及其时、空分布特征，将它们划分为加里东期成矿系列和印支期成矿系列，进而又将加里东期成矿系列划分为铅、锌成矿亚系列，铁、铅、锌成矿亚系列和铅、锌、钨、锡、钼成矿亚系列。

The catalytical activity of organic lead salts is better than that of inorganic lead salts,It appears that the active hydrogen in lead salicylate and lead o-amino benzoate does not interfere with the curing reaction.

有机铝盐的催化活性优于无机铅盐。水杨酸铅(LS和邻氨基苯甲酸铅中的活泼氢不干扰固化反应的进行。

Therefore, researches to develop new lead-free solders that do not contain lead have been pursued. From these points of view, it is impendency to develop the Wetting Balance Tester, which can measure the surface tension of solder alloy easily.

另外，由于铅有毒，研制无铅钎料就显得非常迫切和重要，其中无铅钎料的表面张力作为钎料的重要物理性能指标之一是非常值得定量研究的，因此研制润湿力测量仪非常必要。

At this point, sheet resistivity is minimal. Meanwhile, TCR and the refiring change ratio is near to zero. Compound inorganic binder was put forward firstly. The controllable regulation on refiring change ratio can be acquired by linear principle. When the volume ratio is 1:1, the best sintering temperature is 865℃.

实验发现，复合无机粘结相对膜层电性能和重烧变化率的影响近似满足线性复合效应；采用体积比为1：1的钙铝硅玻璃和铅硼硅玻璃作为复合无机粘结相，最佳烧结温度在865℃；铅硼硅玻璃与钌酸铋置换反应生成钌酸铅&过渡层&，实现界面的渐变，使膜层性能得到改善。

Two factors that could restrain a rally are large unreported inventories of lead believed to have been stockpiled in China this year and sluggish demand outside of China.

铅价也面临着两大限制上涨的因素：市场认为中国今年储备了大量的铅库存，中国以外地区的铅需求一直疲软。

And then, synthesizing of middle chrome, light chrome and lemon chrome through the reaction of leachate with Pb(CH3COO)2 and Pb(NO3)2 were studied respectively.

将铬渣淋滤液与乙酸铅和硝酸铅进行反应，分别进行了中铬黄、浅铬黄和柠檬铬黄的生成试验，研究了滤液中六价铬浓度和铅盐的用量对铬黄生成反应的影响。

Six years later, John Roebuck in England adapted principium of nitroso process to build up a 6ft (1.89m) square lead-line chamber and carried out nitroso process reaction inside.

经过6年后，按亚硝基法原理，英国人丁·罗巴克在伯明翰建成一座6ft(1.89m)见方的铅室，在铅室内进行上述亚硝基制酸反应，成为世界上最早的铅室法制酸工厂。

Pb isotope values of Chukchi Sea and the Bering Sea are within the scope of northern Pacific"s, and closing to lead isotope average of Lena River"s in eastern Siberia flowing into the Laptev Sea,and north Pacific especially impact on the Bering Sea.(6)Lower ?

楚科奇海和白令海铅同位素值在太平洋北部铅同位素值变化范围之内，并且与流入北极拉普捷夫海的西伯利亚东部勒拿河铅同位素平均值接近，太平洋北部尤以对白令海的影响更为明显。

Pb isotope values of Chukchi Sea and the Bering Sea are within the scope of northern Pacific\'s, and closing to lead isotope average of Lena River\'s in eastern Siberia flowing into the Laptev Sea,and north Pacific especially impact on the Bering Sea.(6)Lower ?

楚科奇海和白令海铅同位素值在太平洋北部铅同位素值变化范围之内，并且与流进北极拉普捷夫海的西伯利亚东部勒拿河铅同位素均匀值接近，太平洋北部尤以对白令海的影响更为明显。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
