核心问题
Provided that a sufficient mass of uranium is disposed in a number of rods through the moderator, a high enough proportion of the emitted neutrons will find their way to fissile nuclei to produce a chain reaction. (The Structure of Technical English, p.111)
[原译]如果将足够数量的铀，制成若干铀棒插入减速剂内，则绝大部分放射出的中子，将达到裂变核子速度而产生链式反应。（中译本）
说“中子达到裂变核子速度”与物理常识相违背，请分析。
词典解答
find one's way to 这个短语的意思不是“达到……速度”，而是“到达”“进入”（参见 find one's way）。例如：
Slang often finds its way into colloquial English.
俚语常常渗透到日常口语里来。
[试译]如果插放在减速剂中的一些铀棒有足够质量的铀可供利用,则放射出来的中子
lose way/lose the way 1616
就会有很大一部分进入裂变核，而引起链式反应。
lose way/lose the way 见 lose the way
make way/make one's way 见 lose heart
weapon/arms 见 weapon/weaponry
