标题[疑问]何谓mean free path?

如题...
Hill的General Chemistry第四版...
第五章GASES...201页第三段第一句...
The average distance a molecule travels between collisions is called its
mean free path.At sea level, the mean free path of an N2 or O2 molecule is
only about 6 * 10^-8 m.
这段对mean free path的定义不能理解...
麻烦各位大大帮说明一下...
感激不尽....
