最近四十年发展起来的各种电子引伸计在讯号放大及数据采集和处理方面有非常突出的优点，但大多数电子引伸计如单侧电子引伸计(图1)、光栅引伸计和视频引伸计都是测量拉伸试样单侧的变形[3]，笔者称它们为单侧电子引伸计。

The one-side electronic extensometer fastened on only one side of tensile specimen cannot eliminate the effect of bend of eccentric tension. The results of measurement of such electronic extensometer are instable and then more errors may be included.

目前，国内外使用的电子引伸计多数是测量拉伸试样单侧的变形，由于拉伸试样往往发生偏心拉伸，单侧测量的引伸计无法扣除偏心拉伸的影响，因而其测量结果极不稳定和产生比较大的误差。

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。

In according to the self-circulating of money , money is money, it does not point out the material of money. Electronic money shows its value with numeral, and uses the data encryption system to protect itself from falsifier. As long as the numeral of material is decided by users, electronic money will become a real money with anonymity, transferability and relativity.
