包覆药中增塑剂的迁移及其分布

The Migration and Distribution of Plasticizer in Covering Propellant。

该文运用ＨＰＬＣ法，采用两种制样方式，研究测定了包覆药中增塑剂二硝基甲苯的迁移行为，比较了两种制样方法的优劣，给出了二硝基甲苯在７０℃时的迁移分布及总迁移量随时间变化的函数关系．

Two methods for preparing testsample are introduced in this paper.The migration of plasticizer dinitrotoluene in coveringpropellant is studied and determined by the method of HPLC,And the advantages and disadvanges are compared between the two methods,The functional reatationship of migration distribution of dintrololuene under 70 ℃ and overall migration variation with time were given herein。
