在文本中研究了通常观察到的由氢燃料球团烧蚀形成的环形排列细丝。烧蚀剂在临界半径附近形成第一个可区分的灯丝，这似乎是q=2表面的半径。其他细丝的位置可以通过弹丸的弹道运动和弹丸烧蚀的简单时间依赖模型来预测。这些实验结果表明，可能需要一个时间相关的模型作为现有烧蚀模型的改进。
The toroidally aligned filaments which are commonly observed to be formed by the ablation of a hydrogen fuelling pellet have been studied in TEXT. The ablatant forms the first distinguishable filament near a critical radius, which appears to be that of the q=2 surface. The positions of the other filaments can be predicted from the ballistic motion of the pellet and a simple time dependent model for pellet ablation. These experimental results indicate that a time dependent model may be required as a refinement of present ablation models.
