摘要
Pauling在其著名的专著中，首先提出并详细论述了有关化学键能(chemical bond energy)的概念。随着质谱和光谱测试技术的进展，现代物理化学中又建立了键分离能(bond dissociation energy)的概念并得到广泛应用。
It is estimated that the uranium-oxygen bond dissociation energy (Du+-o=350 kcal mole) is higher than silicon- and aluminium bond dissociation energies (Dsi4+-o=302, DAl3+-o = 264 kcal mole). During the process of magmatic differentiation with the in-crease of the degree of polymerization for silicon-oxygen complex ion, uranium in gra-nitic melts tends to combine with oxygen to form the coordination polyhedron [U0x]2x-n and also occur in the form of nuclei and crystals of uranite, as has been demonstrated by the induced fission-track study of quartz syenite from Huangmei jian.
