Abstract

In the article "String as a theory of everything" by M. Mitchell Waldrop (Research News, 20 Sept., p. 1251), the last line of the first column was inadvertantly omitted. The affected sentence should have read, "Not only were the strong interactions far more complex than predicted by field theory, but the particles that participated in the strong interactions-the hadrons, a group that includes protons, neutrons, pi mesons, and many others-seemed to be relatively large, extended objects as much as 1 Fermi across (10(-13) centimeter)." In the next-to-the-last line of the second full paragraph in column 2 on page 1252, 10(-19) should have been 10(+19). Finally, the words "quandary" (page 1251, column 1, paragraph 6, line 2) and "quark" (page 1252, column 3, last paragraph, line 18) were misspelled.

摘要

在 M. Mitchell Waldrop 的文章“String 作为万物理论”（研究新闻，9 月 20 日，第 1251 页）中，第一列最后一行被误删。受影响的句子应该是：“不仅强相互作用比场论预测的要复杂得多，而且参与强相互作用的粒子——强子，这是一个包括质子、中子、π介子和许多其他粒子的群体——似乎是相对较大的、延伸的物体，跨越 1 费米（10^(-13) 厘米）。”在第 1252 页第二栏倒数第二行中，10^(-19) 应该是 10^(+19)。最后，“困境”（第 1251 页，第 1 栏，第 6 段，第 2 行）和“夸克”（第 1252 页，第 3 栏，最后一段，第 18 行）拼错了。
