摘　　要：泡孔逸出理论在微发泡研究领域经常被提及,但这一理论的真实性却从未被验证过。该实验利用自制模具的一些特殊功能,自行设计了一套实验方案,成功否定了熔胶中混有的气泡在高压条件下会从熔胶中完全逸出的可能性。从而判定泡孔逸出理论存在有些错误。Foam-escaping theory was often used in the research field in microcellular foaming field. But this theory had never been approved. Base on a self-made mold with the some special functions, an experiment project was designed, and successfully negated the possibilities that the bubbles mixed would completely escape from the melt glue in the high-pressure conditions, thus proved the existence of gas-escaping theory had some errors.
