随机

• 拼音: suí jī
• 汉字拆解: 随 = to follow, go along with; 机 = 木 (wood radical) + 几 (small table, mechanism) — a mechanism or opportunity arising by chance

含义

Random; occurring without a fixed pattern or predetermined order. Also: adaptive, responsive to circumstances as they arise.

Used in statistics (随机抽样 — random sampling), computing (随机数 — random number), and everyday speech (随机应变 — adapt flexibly to circumstances). The dual meaning of 'random' and 'adaptive' reflects its two distinct but related uses. Collocates: 随机性、随机变量、随机分配、随机抽查.
