A research for a comprehensive evaluating index system for urban - afforestation - oriented tree seeds of shenyang 沈陽城市綠化樹種綜合評價指標體系研究
In this thesis , we study the non - invertible linear finite autonomous automata and derive the following new results : 1 . a formula is given to count the number of the nodes of every level in a down - oriented tree of an autonomous automaton . then a necessary and sufficient condition is presented for the graph of an autonomous automaton to be an exact - equibranch down - oriented tree [ theorem 3 . 2 - 3 . 3 ] 本文研究了布爾代數上非可逆的線性內動機,取得了下列成果: ( 1 )給出了線性內動機下向樹形中每一層節(jié)點的計數公式和下向樹是等叉下向樹形的判定條件[定理3 . 2 3 . 3 ] 。
