Calculation adopted to calculate values is FDM(finite difference method). Grid and limited nodes are used to simulate the whole magnet while the effect of excessive layer is simplified as the function of the limited nodes on both sides of the interface. Thus the constant, whose unit is the same to the one of the exchange constant in block,plays its role in computational process among joints only which is not a breach of the specific physical image.

求大神幫忙翻譯一下這段話：由于計(jì)算方法在數(shù)值計(jì)算上用的是有限差分法并且是用網(wǎng)格和有限的節(jié)點(diǎn)來模擬整個(gè)磁體，將過度層的影響簡化為界面兩邊的有限的節(jié)點(diǎn)的作用，所以這個(gè)常數(shù)僅僅在節(jié)點(diǎn)間的計(jì)算過程中起作用，單位與塊體的交換常數(shù)單位相同，并沒有違背具體的物理圖像.
The constant functions only in the calculation of nodes, with the same unit as that of block exchange constant and so not breaching the specific physical image, since the calculation is finite difference method and uses grids and limited nodes to simulate the whole magnet, simplifying the effect of excessive layer into that of the limited nodes on both sides of the interface.

何謂 "過度層" ?
  十邊形用六邊形約, "過度" = "多余"  ( excess ) ??
  還是 "內(nèi)層"  ( internal layers ) ??

"塊體的交換常數(shù)"  起什么作用 ??
你用另一  "這個(gè)常數(shù)"  好象愛因斯坦用 "宇宙學(xué)常數(shù)"  敷衍交代

Because the calculation method on the numerical calculation with the finite difference method and grid and limited number of nodes to simulate the whole magnet, simplified interface on both sides of the limited impact of excessive layers of nodes, so this constant only between nodes during calculation work, units and blocks have the same Exchange constants, units, and not contrary to the specific physical image.
