摘要
螯合物的特殊稳定性在许多方面得到广泛应用，但其稳定性的原因未见有关资料详细报道。从原子结构和热力学两方面对其阐述之，澄清了人们对其的模糊认识。
The special stability of chelete is widely used in many ways. But there is no de- tailed report about the reason of its stability in revelent data. From atomic structure and thermodynamics the paper analyses the reason and clears up the indistinct recognition.
