The main resultsare as follows:(1) Pterocarya stenoptera mainly scattered in Hubei province, planted by the side ofhouse, rivers and beach edge and cultivation of large plantations was rare. Thedistribution of genetic resources of Pterocarya stenoptera was relatively scattered.

主要结果如下：(1)我省的枫杨主要是散生分布，多种植于房前屋后和河流、滩地边，大片种植的人工林极少，所以遗传资源分布比较分散。

The pyridinium salts was transformed by the base to 1-hydroxy or 3-hydroxy-quinolizinylides, which undergo 1,3-dipolar cycloadditionreaction with alkenes,and then aromatizated to cycl[3,3,2]azinone in thepresence of oxidant.

实验证明，这是一个连续进行的多步反应：2-羰基吡啶鎓盐在反应中先生成1-羟基或3-羟基喹嗪叶立德，然后与烯烃起1，3—偶极加成反应，最后在氧化剂作用下脱氢芳构化而生成Cycl[3，3，2]azinone。

Finally, the paper summarizes the meaningful experience and gives us a lot of enlightenments that we can learn from characteristic management philosophy and corporate culture of Haier Group. That is to say, corporate culture construction, is neither a simple "transplant" from western corporate culture, nor a "colon" of traditional culture, but a "genie reforger" with modern culture.
