当你的对手阵脚被打乱或是撤退机甲的时候，特种兵apc是非常有效的。更不用提它的反步兵能力了。
APC can be very effective during times when your opponent is distracted or retreating walker units. Not to mention having a more than handy Anti Infantry weapon.

The Commando APC can be very effective during times when your opponent is distracted or retreating walker units. Not to mention having a more than handy Anti Infantry weapon.
对于函数和常量，如果当前的名称空间不包含这个函数或常量，PHP的后退机制会后退到标准的php函数。
For functions and constants, if the current namespace does not contain that function or constant, PHP's fallback mechanism will fall back to the standard PHP function.
在火炮制退机中采用磁流变液体，通过改变磁流变液体粘度来调节阻尼，形成液压阻力，也可控制后坐阻力规律。
Using MR fluids in recoil brake of gun, the damping can be regulated by means of changing consistence of MR fluids to form hydraulic resistance, and law of recoil resistance can also be controled.

请注意，相对XSLT 1.0规范，关于什么情况下应用回退机制的说明在 XSLT 2.0 规范中更细化了。
Note that the text about when the fallback mechanism is applied in the XSLT 2.0 spec is refined compared to the XSLT 1.0 spec.
测试驻退机湍流速度场的目的是逐步揭示驻退机内湍流流场的结构和特点，为驻退机的设计和改进提供一些有益的参考。

由于xsl:with-param不是 xsl:apply-imports顺序构造器的一部分，不适用回退机制。
Since the xsl:with-param is not part of a sequence constructor of xsl:apply-imports, the fallback mechanism is not applicable.
Bayeux和WebSockets都试图避免资源限制问题，使用回退机制来实现长轮询(比如Bayeux)，或者切换到其他非http协议之上。
Both Bayeux and WebSockets attempt to avoid the resource limits by using a fall-back mechanism for long polling (in the case of Bayeux) or switching to a non-HTTP based secondary protocol instead.
