All four describe standing straight or vertical. Vertical is technical, for surfaces. Standing is the everyday word, for a person on their feet. Erect is formal, for a straight, rigid body. Upright describes furniture standing vertically, or good posture. Other senses are not compared here.

这四个词都表示“直立、垂直”的状态，但用法和语域不同：vertical 是几何、技术性词汇，多用于描述表面、线条或物体与地面成直角；standing 是最日常中性的词，指人或动物用双脚站立；erect 较正式或文学化，强调身体挺直、僵直；upright 常用于家具、座椅等物体呈垂直状态，也可指良好的站姿。这里不比较 erect 作动词“建造”的意思，也不比较 upright 表示“正直的”的意思，以及 standing 表示“持续的、资历”的意思。

Permanent, standing, perpetual, and eternal all mean lasting. Permanent is the plain, everyday word, opposite of temporary. Standing is formal, describing a rule or arrangement in effect indefinitely. Perpetual stresses something repeating again and again, often annoyingly. Eternal is poetic, used for love or life.

这四个词都可以表示“持久、不会消失”，但语气和使用场合不同：permanent 最常用、最中性，指与temporary相对的“永久”；standing 多用于正式场合，指规则、邀请、机构等“长期有效的”安排；perpetual 强调“持续不断、反复发生”，常带一点厌烦或夸张的语气；eternal 语气最诗意、夸张，常用于爱情、生命等抽象事物的“永恒”。这里不比较 standing 表示“站立”的动词义，也不比较其作名词表示“声誉、地位”的用法。
