简介：这篇文章的目的是在Morita类型的稳定的等价下面学习联合代数学的某invariants。首先，我们证明如果二有限维的self-injectivek代数学Morita类型是稳定地相等的，那么，他们的轨道代数学是同形的。第二，代数学的quasitilted性质在Morita类型的稳定的等价下面是不变的，这被验证。作为这结果的应用，如果代数学具有有限表示类型，那么，它的倾斜的性质在Morita类型的稳定的等价下面是不变的，这被获得；到部分倾斜的模块的另外的申请在节4被给。最后，我们证明当二有限维的k代数学Morita类型是稳定地相等的时，他们的重复代数学在某些条件下面的Morita类型也是稳定地相等的。
