当谈论产品进入市场，正式向公众亮相的时刻，用英语如何表达呢？"产品上线"这个词在英语中有多重表述，让我们一起来探索一番。
无疑，"launch"是最常见的选择，它不仅意味着发起或启动一项重要活动，更是新产品或服务发布的代名词。例如：
The social media giant is launching an app built specifically for creators.
这家社交媒体巨头即将推出专为创作者打造的应用程序。
然而，product launch 是专业术语，准确指代新产品首次投入市场的活动：
The debut of a product into the market. The product launch signifies the point at which consumers first have access to a new product.
新产品首次在市场上亮相，是消费者首次接触的时刻。
但要注意，"launch"也可能表示测试阶段，尽管尚未正式发布：
Even if a product is still in testing, the term 'launch' could indicate its initial exposure.
Product Manager Bowen Pan announced the release of Lasso for iOS and Android, a TikTok competitor.
Screen Time will be available with iOS 12, the latest version of Apple's mobile operating system.
The new computer system was supposed to go live today, despite some lingering issues.
而关于成功上线的策略，可以参考"Ready for Launch: Five Steps for a Successful Go-Live"。
