从方程9中，我们可以看到A的大小关系由B(B1/B2)决定。然而根据方程3b，B是与C是密切相关的。这也就是说明要确定B的话，我们需要先确定C1和C2。因此，我们在图1里面就给出了不对称TGNJ的C1和C2之间的关系。从图中我们可以清楚的看到C1要明显小于C2，这是由于左电极宽度要小于右电极宽度。因此，B1要大于B2，i.e., B>1. 我们把B的值代入方程9,我们就最终获得了A的大小关系。
From Eq. 9 it can be seen that the magnitude of A is determined from B (B=B1/B2). The magnitude of B, however, is calculated from C using Eq. 3b. In the other words, the values of C1 and C2 have to be found first before estimating the value of B. To do so, the relationship between C1 and C2 for an asymmetric TGNJ is given in Fig. 1. It shows that C1 is much smaller than C2 since the left terminal is narrower than the right one. In turn, B1 is larger than B2 with the resultant B value of larger than 1. Finally, by substituting the value of B into Eq. 9, the magnitude of A can be obtained. |
