换句话说，对最内层循环的情况下，不依赖于任何其他的结果，所以他们可以在自己的线程同时运行。

In other words, none of the instances of the innermost loop depend on the results of any other, so they could run simultaneously on their own threads.

针对原有LEAP程序只能执行最内层循环，所能执行程序范围非常有限的缺点，增加其对多层循环自动加载和执行机制的支持。

Aiming at the shortage that the old LEAP can only run single-layer loop, which greatly limit the kinds of programs it can reform, we will enhance the LEAP to run multi-layers loop.
