To bring FLASH therapy out of the lab and into clinical use, researchers like Vozenin and Loo needed machines capable of delivering fast, high doses with pinpoint precision deep inside the body. Most early studies relied on low-energy electron beams like Favaudon’s 4.5-megaelectron-volt Kinetron—sufficient for surface tumors, but unable to reach more than a few centimeters into a human body. Treating deep-seated cancers in the lung, brain, or abdomen would require far higher particle energies.

One important distinction: for a fixnum, the upper bits hold the integer value directly (an immediate). For all other types, those bits are a heap pointer to the underlying C struct.。新收录的资料对此有专业解读

“通过沉降、气浮、过滤以及加入化学药剂等方式，处理厂能够将采出水中的泥沙、油滴、悬浮物等从污水分离出来，使污水变为可循环利用的合格水。”陈文昱说，处理后的采出水将再次通过注水增压泵站，注入到油田的目标油层中，实现水资源有效循环，避免了污水外排造成的生态环境污染。
