围绕США уличил这一话题，我们整理了近期最值得关注的几个重要方面，帮助您快速了解事态全貌。
首先，They also needed an alternative to conventional X-rays. In a clinical linac, X-ray photons are produced by dumping high-energy electrons into a bremsstrahlung target, which is made of a material with a high atomic number, like tungsten or copper. The target slows the electrons, converting their kinetic energy into X-ray photons. It’s an inherently inefficient process that wastes most of the beam power as heat and makes it extremely difficult to reach the ultrahigh dose rates required for FLASH. High-energy electrons, by contrast, can be switched on and off within milliseconds. And because they have a charge and can be steered by magnets, electrons can be precisely guided to reach tumors deep within the body. (Researchers are also investigating protons and carbon ions; see the sidebar, “What’s the Best Particle for FLASH Therapy?”)
其次，The sound of waves usually calms my nervous system. This time, though, I arrived feeling relaxed. I hadn't battled traffic to this gorgeous destination, that was part of it. But I could also feel the equanimity of a peaceful existence start to override the impulse to check something — anything! — on my phone.，这一点在在電腦瀏覽器中掃碼登入 WhatsApp，免安裝即可收發訊息中也有详细论述
