美国国防部的“主动拒止系统”发射能量束，会让人产生“皮肤表面剧烈灼热感”。据报道，美国国防部长皮特·赫格塞斯上个月签署了一份备忘录，允许国土安全部（DHS）测试一种名为“热射线”的非致命武器，以评估其在美墨边境的潜在用途。
The Pentagon’s Active Denial System shoots energy beam that causes ‘sensation of intense heat on surface of skin’ Pete Hegseth, the US secretary of defense, reportedly signed a memo last month permitting the Department of Homeland Security (DHS) to test a non-lethal “heat ray” for potential use at the US southern border.
这种“热射线”即“主动拒止系统”，属于军用级武器，根据美国国防大学2009年关于该武器的案例研究，它发射的能量束会引起“皮肤表面剧烈灼热感”。
The “heat ray”, known as the Active Denial System, is a military-grade weapon that shoots an energy beam causing “a sensation of intense heat on the surface of the skin”, according to a 2009 National Defense University case study on the weapon.
