adj.自力推进的；机动式的
Adopting self Propelled tram's ring like track for the haulage from mine pit mouth to mine run bin lead the mine tram to self return,self sliding and self rotating. 矿山井口到原矿仓运输采用自动环形道,使矿车自升、自溜、自回。
Based on analysis of the finite element method(FEM) models exported from CAD software, a method for parametrically establishing FEM models for self propelled gun is presented in this paper. 该文通过对典型的CAD软件输出的有限元模型的分析,提出了自行火炮有限元参数化建模方法。
