Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

镧系元素属于周期表第六周期中ⅢB族，全部是固体金属，它们是镧、铈、镨、钕、钷、钐、铕、钆、铽、镝、钬、铒、铥、镱和镥共十五种金属元素，它们的外围两层的电子均是5d16s2，而外围第三层的f轨道电子却从零增加到14个，所以外围电子结构为4f0－145d16s2，而使这些元素氧化数均为＋3，化学性质极为接近，提炼时很难分开，它们的矿石又大多是多种元素混在一起的，更增加提纯难度，它们的原子序数为57－71，核内质子数逐个增加，因而对核外电子引力也不断增强，使原子半径随原子序数Z增加而减小，这就使镧系元素收缩、离子半径也缩小，这也使得Zr和Hf，Nb和Ta、Mo和W等原子和离子半径都很接近、也决定了它们彼此性质类似，以致难以分离、也使第Ⅷ族中第五周期的钌、铑、钯和第六周期的锇、铱、铂在性质上极为相似，因而称这六个元素为铂系元素。

The shell of the liquid crystal auto-changing shade welding is made of high-performance plastic which is high strength and without leaking light. In addition to, by adding fire retardant and other special components , it has meet to the demand of inflaming retarding and could bear the high and low temperature .For resistance to impact, besides of choosing lightweight and high strength material, we also consider more in the aspect of the mechanics and human engineering in the design of the structure .In order to insure the comfort for wearing , we make the inside and outside protection piece and the shell of the face guard to a camber shape ,it also enhances the ability of resistance to impact.

液晶自动变光焊接面罩的壳体采用高性能的塑料注塑制作而成，高强度，不漏光，并通过在面罩材料里添加一定配方的阻燃剂和其他特殊成分，达到了阻燃和耐高低温等要求；为了抗冲击，除了材料选择轻质高强度材料外，在结构设计上更多的从力学和人体工程学方面考虑，保证了佩戴的舒适，而将内外保片与面罩壳体结合设计成能够最大承受外界力量的弧型，增加了面罩抗冲击能力。
