The implicit variable is available directly in flow-definition XML files - for instance.

隐式变量可以在流定义xml文件中直接得到，例如。

The second for loop simplifies this process a little by using an implicit variable (that is, one that isn't explicitly created) for the file object.

第二个for循环通过使用file对象的隐式变量(也就是说，变量不是显式创建的)，对这个过程稍做了点儿简化。

Because implicit objects are declared automatically, we need only use the reference variable associated with a given object to begin calling methods on it.

因为隐式对象是自动声明的，所以我们只需要使用与一个给定对象相关的引用变量来调用其方法。
