compensating filter

For the research of influence on the shock distance apart from models by high enthalpy real-gas effect, a technique of instantaneous schliern photography is used, also, a technique of compensate filter to elimilate interference stripe and spontaneity light of flow filed is used in the experiment.

为了研究高焓真实气体效应对激波脱体距离的影响,本文采用了一种瞬时纹影摄影技术,并为消除流场自发光及干涉条纹的影响使用了补偿式滤光技术。
