人类对自然现象的认识,总是在寻找它的规律,并力图解释产生这种规律的内在原因。从本世纪初到三十年代中,许多地质科学家探讨元素在整个地质历史中分离和结合的规律,逐步建立了品格能学说。品格能理论主要考虑了两方面的因素;一是离子电荷(电价)的特殊作用;另是离子大小(半径)的 Human understanding of natural phenomena, always looking for its laws, and trying to explain the inherent causes of this law. From the beginning of this century to the 1930s, many geoscientists discussed the law of element separation and combination throughout geologic history and gradually established the theory of character and energy. Character theory can mainly consider two factors: one is the special role of ion charge (electricity price); the other is ion size (radius)
