通过运用由刘儒英教授提出[参见离散数学,1997,172:85-92]的伴随多项式理论和最小根定理[参见离散数学,2004,281:277-294],给出了一类三叉树的伴随等价图。
补充资料:树正瀑布
树正瀑布在树正群海的上游游人如织的树正寨前公路旁,是入沟见到的第一个瀑布,也是九寨沟四大瀑布中最小的一个。虽然最小,但也能让初游九寨沟的人惊心动魄。树正瀑布海拔2295米,高11米,瀑顶宽62米,是无名海水沿湖堤奔突,被水中树丛分成数以千计的水束汇集到树正瀑顶。一到裂点就喷扬出来,随着下方凸起的裙状、肺叶状钙华,构成多极浑圆状瀑布。瀑布飞落溪涧,神采飘逸,雄厚的瀑声,旋律刚毅,雪峰银瀑,绿树翠流,构成印象画般的背景,瀑边留影,如诗如梦。
上游的湖水沿着浅滩四处漫流,被水中的树丛分成无数股水流,最后汇集到树正瀑布顶端的山崖边,奔流附落,水雾四散,构成了神采飘逸,气度雍容的一片水帘。
