Furthermore, the metallic glass samples are prepared by vacuum injection method and the rationality of above-mentioned relationships and RBF models is directly verified. It is shown that there are extremum phenomena between the Rc andΔd ,Δe and v respectively. However, the positions of the extremum are different from different alloy systems and the extremum phenomena may be related to the optimum composition region and the optimum additive quantity. More elements in the alloy are in favor of the improvement of the GFA. And as for the high GFA alloy, the atomic percentage, atomic radius difference and atomic electronegativity difference are harmoniously matched.

d、Δe和v与临界冷却速度Rc的关系中都出现极值现象，对于不同的合金体系，极值出现的位置不同；金属玻璃的最优成分范围以及各种添加元素的最佳添加量行为，可能与此极值现象相关；合金中包含的组元数目多有利于提高其玻璃形成能力，玻璃形成能力强的合金，其各个组元的原子百分含量、组元原子半径差及其电负性差之间的搭配是很和谐的；融合建模的合金系之间包含的主要组元数量和种类越相近，所建立的模型的可靠程度越高，其预测结果与实测结果越吻合。

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 thesis consists of six chapters. In the first, the technologies of atomic force microscopy and of the measurement elasticity of biomolecules were introduced. In the second, the validity of VSPFM was confirmed by lift mode atomic force microscopy. In this chapter, the height of DNA was measured by lift mode atomic force microscopy, which demonstrated that the method of height measurement of biomolecules by VSPFM was correct and established the foundation of the method of measurement elasticity of biomolecules by vibrating mode scanning polarization force microscopy. In the third chapter, detailed work has been illustrated on the foundation of the method of measurement elasticity of biomolecules by VSPFM. And the compressive elasticity of DNA was measured.
