而且与传统矽肺相比，人造石英石所致矽肺进展更快、死亡率更高。“这类疾病早期往往没有明显症状，等到确诊时，患者常常已发展至二期甚至三期。对于进入三期的患者而言，肺移植可能是唯一选择，但可供捐献的肺源又十分有限。”。业内人士推荐新收录的资料作为进阶阅读

The SPARCstation IPC and IPX share the same power supply and this web page gives a description of replacing the electrolytics in a PSU from an IPC. Interestingly, the author notes elsewhere that they had two IPCs with dead PSUs, whereas one fitted in an IPX worked fine. However, the IPC is a slightly earlier model and it could simply be that these were older, else perhaps pure chance. In any case, I have two IPXs and both of which with suffered from dead power supplies.

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?”)
