title: [Determination of dimethyldiphenylurea in dibase-propellant by gas chromatography].
abstract: By using gas chromatography external standard method, dimethyldiphenylurea in the storage propellant was separated and determined. Being compared with the conventional bromination method, this one is more rapid, precise and reproducible. Moreover, it can provide reliable data for evaluationg the quality grade of the propellant.
