笔者认为 2 0 0 4年普通高校招生统一考试理科综合第 1 4题有问题 .[原题 ]本题中用大写字母代表原子核 .E经α衰变成为F ,再经 β衰变成为G ,再经α衰变成为H ,上述系列衰变可记为下式 :E α F β G α H .另一系列衰变如下 :P β Q β R α S .已知P是F的同位素 ,则(A)Q是G的 The author believes that there was a problem in the first four-hundred-thirty-fourth problem in the unified examination of college admissions in 2004. [The original title] Capital letters are used to represent the nucleus in this question. E decays from α to F, and then β becomes G, and then α. The decay becomes H, and the above series of decays can be written as follows: E α F β G α H . Another series of decay is as follows: P β Q β R α S . Knowing that P is an isotope of F, then (A) Q is G of
