如果发生巨变，穿过塑料的中子就会引发材料内质子反冲，从而留下痕迹。

If fusion was taking place, then neutrons flying through the plastic would cause protons within the material to recoil, leaving telltale tracks.

中子通量用伴随粒子法测定，并与反冲质子望远镜相比较，两种方法在1—2%的误差范围内一致。

The associated particle method was used to determine the absolute neutron flux and compared with the recoil proton telescope. The agreement between both methods appeared to be within 1—2%.
