• To disable indirect recursion of after triggers , also set the nested triggers
  若要禁用after触发器的间接递归，还必须将
• Direct recursion of triggers occurs in either of the following circumstances
  在下列任一情况下，都会发生直接触发器递归：
• Disabling the recursive triggers setting only prevents direct recursions
  禁用recursive _ triggers的设置只能阻止直接递归。
• Left recursion is used so that the rule can be reduced after each message
  为了归约每个消息之后的规则，使用的是向左递归。
• Maximum recursion level
  最小递归级别
• E . using a recursive common table expression to display two levels of recursion

• Now , you might ask which method is better ? recursion or non - recursion
  这时你会问哪种方法更好一些呢? ?是递归法还是非递归法？
• This would be unusual in c . however , in xslt , recursion is the only option
  在c中很少这样做，但是在xslt中，这是惟一的办法。
• Fp is also characterized by its use of recursion as a mechanism for control flow
  Fp还有一个特点是用递归做为控制流程的机制。
