1. Instead of the alarm triggering just once at each recurrence, checking this option makes the alarm trigger multiple times at each recurrence. 17此选项可让提醒触发器在每次重现时触发多次而非一次。
2. On conforming level 2 implementations, utilities that process regular expressions shall support Basic Regular Expression (BRE) and Extended Regular Expression (ERE) as specified in [POSIX. 2]. 在二级一致性实现中，处理正则表达式的实用工具必须支持如[POSIX。2]中规定的基本正则表达式（BRE）和扩展正则表达式（ERE）。
3. The algorithm bas been realized by computer programming, and for any input regular expression, a simplified DFA equivalent to the regular expression is produced. 这个算法在计算机上已实现，并且对输入的任意正则表达式，都可以输出等价于正则表达式的简化DFA。
4. Aiming at the problem of formula of regular structure stabilizer rigidity, their bending round being taken into account, formulae of the regular and the irregular are exemplarily deduced by Kar. 针对大多文献就规则结构稳定杆刚度计算公式存在的问题，提出了在考虑稳定杆弯曲圆角的前提下，用卡氏定理举例推导了规则和非规则结构稳定杆的刚度公式，并作了计算分析。
5. As a regular reader of Hints for Heloise, I am pretty educated on the ridiculous number of uses for regular old baking soda. 作为一个《海洛威兹的建议》的长期读者，我知道苏打粉的一些离谱的多种不同用法。
