通信词汇： 饱和容量 （saturation throughput） which is a fundamental performance figure defined as the limit reached by the system throughput as the offered load increases, and it represents the maximum load that the system can carry in stable conditions (as in most random access protocols, the maximum throughput may be greater than the saturation one, but it is of no practical importance as not sustainable for “long” time—see a general discussion about stability。 饱和容量表示的是：随着负载的增加，系统吞吐量的一种极限表达形式，表示了系统在稳定状态的最大的负载。 在大多数的随机接入协议中，最大吞吐量可能会比饱和吞吐量大，但是最大吞吐量对于长期来说没有什么实际意义。
