引用规则原文 the server in doubles tennis can choose to serve from anywhere behind and along the baseline from the center mark to the doubles sideline on the team's end of the court. 也就是说双打发球时, 应在底线后方, 中间标线和双打边线之间, 球场范围内任何点发球。 双打有效发球区, 与单打场地相同。单打边线, 发球线仍是双打时发球区的边线, 发球线, 但在无人区的单打边线, 在双打球场或可忽略。

我懂他的意思,的确是干货。如果能提升一点语言表达能力听懂的人应该会多一些。

乾貨這詞, 年來呈正向話兒, 有了新意, 指簡潔摘要, 表達中肯有重點, 不灌水不偏私見
