在大螺旋器件等离子体放电中，当等离子体无碰撞时(n/m=1/1)，外加模式数(n/m=1/1)的岛的大小显著减小(nu(*)<；约为1)，并且岛位置的β有限(约为0.1%)。另一方面，对于有限β的碰撞等离子体，岛的大小增加。然而，在真空岛大小方面有一个临界点，低于这个临界点就看不到岛的扩大。
In the Large Helical Device plasma discharges, the size of an externally imposed island with mode number ( n/m = 1/1) decreases substantially when the plasma is collisionless ( nu(*)< approximately 1) and the beta is finite ( > approximately 0.1%) at the island location. For the collisional plasmas with finite beta, on the other hand, the size of the island increases. However, there is a threshold in terms of the vacuum island size below which the island enlargement is not seen.
