在德拜-希耶克尔理论中，假设T很小，以至于S“7可以用1+Rn代替。然而，我们希望将公式(5)应用于两个平行板，这两个平行板之间的距离b相隔很近，并且带着如此高的正电荷，使得板之间的任何地方都有n>；和1。因此不能使用德拜-希克尔近似，而是我们可以忽略8“7英寸公式(5)，因为它与icq相比很小。积分得到0=2exp(-Tim/2)tan-：[eexp(i-Tim)-1](6)其中Tm是出现在板中间平面上的Tn的最小值，而0测量到这个中面的距离。如果Tn1和01是板表面上的n和0的值
In the Debye-Hiuekel theory it is assumed that T is so small that s" 7 can be replaced by 1+ rn. We wish, however, to apply Eq.(5) to two parallel plates which are separated by the distance b but are so close together and are so highly positively charged that n>> 1, everywhere between the plates. The Debye-Hiiekel approximation therefore can not be used, but instead, we can neglect 8" 7in Eq.(5), since it is small compared to icq.Integration gives 0= 2 exp (-TiM/2) tan-:[eexp (i-TiM)-1](6) where Tnm is the minimum value of Tn which occurs at the plane half way between the plates and 0 measures the distance from this median plane. If Tn1 and 01 are the values of n and 0 at the surface of the plates and
