结果表明，不同生态环境中生长的马齿苋解剖结构显著不同，盐生马齿苋具有适应盐渍环境的结构特征，这些特征表现为：营养器官通气组织发达；根的次生结构中木栓发达；根、茎的薄壁组织中含有大量的黏液细胞和糊粉粒；叶片表皮的角质膜厚；叶肉中含晶细胞、叶绿体及贮水组织丰富；而这些特征是黑土地上生长的马齿苋所不具备的。

In Chapter 4, there are two important structures, loops and stacks for an abstract single-strand RNA. Based on the method of combinatorial enumeration, we make a new discussion about the enumeration problem and get its approximation with the limited length of end loop.
