在手征强子模型的框架下研究了多波长物质。结果表明，由于每个重子的奇异性和强子物质的密度不同，由{N，Λ}组成的多波长物质是一种亚稳态。有效拉姆达质量随着重子密度的增加而减小，并且始终大于核子的有效拉姆达质量。
Multi-lambda matter is investigated in the framework of a chiral hadronic model. It is shown that multi-lambda matter consisting of {N, Λ} is a metastable state as the strangeness per baryon and the density of hadronic matter are varied. The effective lambda mass decreases as the baryon density increases and remains larger than that of the nucleon.
