fail-safe

fail-safe的音标是[feɪl ˈseɪf]，中文翻译为"安全失效"。"fail-safe"通常用于描述一种系统设计，在这种设计中，如果发生特定情况（如故障），系统会自动进入安全模式，以防止损害。速记技巧可以是将其分解为单词"fail"和"safe"，分别代表"失败"和"安全"，以帮助记忆。

fail-safe这个词来源于英语，意思是“安全失效的”，也就是在系统出现故障时能够自动恢复的机制。它的词源可以追溯到机械工程和自动控制领域。

fail-safe的变化形式主要有复数和过去式、过去分词，分别为failsafes和fail-safed。

相关单词有：safeguard，这个词的意思是“安全防护”，它和fail-safe相反，表示在风险出现时采取的预防措施。此外，fail-safe还可以和其它词组成短语，比如“fail-safe system”，指的是故障安全系统。另一个相关单词是backup，意思是“备份”，在系统出现故障时，备份数据可以用来恢复系统。

fail-safe这个词在英语中经常被使用，特别是在计算机和自动化领域，因为它描述了一种在系统出现故障时能够自动恢复的机制，这对于许多现代设备来说非常重要。

Fail-Safe Equipment in Modern Life

Modern technology has made it possible for us to rely on a wide range of equipment and systems in our daily lives. Among these, fail-safe equipment plays a crucial role in ensuring the safety and reliability of these systems.

Fail-safe equipment is designed to prevent accidents and failures by providing backup systems and procedures that can take over in case of a malfunction or error. From power grids to transportation systems, from medical devices to communication networks, fail-safe equipment is everywhere, ensuring that our critical systems continue to operate safely and reliably.

However, despite the widespread use of fail-safe equipment, we must always remain vigilant and attentive to ensure that these systems are maintained and updated to keep up with technological advancements and changing environments. Only through continuous vigilance and maintenance can we ensure the safety and reliability of our modern lives.
