生物細胞鈉鈣離子交換通道，是以極快的速度讓鈣離子由細胞內與鈉離子交換至細胞外。本研究利用Poisson-Fermi之理論分析NCX(sodium calcium exchanger)之離子結合構造，使我們能夠以數學的方式探討鈉鈣離子在NCX的交換機制，並成功的解釋鈉鈣離子交換之實驗結果。

Biological sodium calcium ion exchange channel (NCX) removes calcium ions very rapidly from cell inside in exchange with sodium ions from outside. The Poisson-Fermi theory is used to analyze the binding potentials of NCX. It allows us to mathematically investigate the sodium-calcium ion exchange mechanism in NCX. Numerical results have been shown to agree with the experimental results of the sodium-calcium ion exchange.
