The results indicate that a rotable plate valve with a novel structure, a secondary demountable mandrel and techniques of both scraping and coating of insulation and automatic weighing of propellant slurry to be loaded are adopted so that the design requirements for propellant loading can be met.
结果采用结构新颖的转板阀,二次装配式芯模,以及刮涂绝热层和自动称量浇注药量技术,使装药达到了设计要求。
It was found that a cobalt-based solid solution with a face-centered cubic crystal structure is presented accompanied by the secondary phase M_7C_3 with a hexagonal crystal structure in the cobalt-based alloy coating.
结果表明,堆焊合金层主要是由面心立方的γ(Co)和六方结构的M7C3构成,并且在钴基固溶体中存在着许多堆垛层错。
