摘要
通过对导体电阻成因的分析,得到导体超导态第一转变温度需满足的条件是在该温度下导体中的电子都应处于束缚态。根据束缚态电子在电场中的Stark效应,解释超导态电子的微观输运图像,进而得出导体超导态转变第一温度的数学表达式。超导体原子的热振动(声子)对原子间的轨域相干有破坏作用,即原子的热振动也是限制超导态转变临界温度的因素,经过分析得到了关于原子热振动的超导态转变第二温度,该转变温度体现的是原子热振动对超导态转变的制约作用。
From the analysis of the origin of conductor resistance, it was known that the first transition temperature of a superconductor was such a temperature at which all the electrons in the conductor should be in a bound state. Microscopic transport images of electrons in superconducting state were described by using the Stark effect of atoms＇ bound electrons in an electric field,and a mathematical expression was then deduced for the first superconducting state transition temperature. The thermal vibration（phonon） of superconductor atoms had a destructive effect on the inter-atom orbital coherence, in other words, the thermal vibration of atoms was another factor restricting the transitional critical temperature of superconducting state. The second superconducting state transition temperature, which was related to atomic thermal vibration, was found by analysis. This temperature reflected the restrictive effect of atomic thermal vibration on superconducting state transition.
