摘　　要：Casimir能量是量子场的一类零点能,是由于边界的出现、时空的弯曲以及某些背景场的存在而引起的。在此,计算了各种不同闭弦体系的Casimir能量,比较了不同弦圈体系的Ca-simir能量,并讨论了一些有关的问题。The Casimir energy is a kind of zero-point energy of quantized fields and can be considered as the energy of vacuum polarization of quantized fields due to the presence of boundaries, the curvature of the space-time manifold or some background fields. In this paper, the Casimir energy for various string loop systems is calculated. Results of different systems are compared and some related topics are discussed.
