通过对各种可能的反应路径的进行计算和比较，排除了亚甲基卡宾和连二烯中间体的可能性，并确定该异构化反应机理包含以下三个步骤：（1）炔丙基吡啶反应在金催化条件下发生分子内的成环得到环状中间体；（2）环状中间体在水分子簇的协助下优先发生1，3-氢迁移反应，异构化得到更为稳定的中间体；（3）最后再进行1，2-氢迁移或是1，2-硅烷基团迁移即得到实验中所观察到的环异构化产物。

Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.

通过室内模拟湖泊沉积物在不同pH条件下，研究释放到水体中各种磷形态的迁移转化行为，结果表明：碱性条件和酸性条件下，水体磷的时空变化由于其释放机制的不同，其迁移转化行为各不相同，同时，pH值的变化对水体中各种磷的相互转化没有明显的作用，各种磷形态的浓度变化，在很大程度上取决于水体中总磷的浓度。

In this paper migration theory and techniques related to the high-energy TEGN gun propellant are presented, and some methods determining the migration of RDX are analyzed and compared. As a result, chemical and thermal analyses are employed associatively to test the content of RDX in different position of TEGN gun propellant stored different period. The antimigration capability of TEGN gun propellant making use of two different granularity of RDX is also been studied.
