摘要
系统地测定和分析了由硬化剂ＮＨ４Ｃｌ、Ａｌｃｌ３和ＭｇＣｌ２所硬化的型壳的常温、高温和残留强度，并对其强度上的差异提出一些新的见解．
Systematic measurement and analysis on the strength of room-tempera-ture and high-temperature,as well as the retained strength for mould shells hardened respec-tively by agents of NH4Cl,AlCl3 and MgCl2 are performed in this paper,and some new view-points about these differences in strength are proposed.
