为了有效预防、控制和扑灭井下火灾，通过煤矿对注氮防灭火的实践应用，认为以注氮为主的防灭火是井下预防火灾和减少火灾损失的一种非常有价值和实用的技术，它可用于煤矿自燃发火的预防、火势控制、窒息火区、可控制的缩封和启封火区。

To guarantee the QOS in this environment, the end to end QOS related information should be intercommunicated, coordinated, and interworked. These requirements should be based on the QOS management of different QOS systems which take part in the service provision of the application. This QOS management means that the requirements of user can be described, the performance and resource of different QOS systems can be predictable, the QOS in the system and among the systems can be negotiated, the heterogeneous resources can be configurable and controllable.

异构QOS环境下的QOS保证，本质上是一个异构QOS系统间的QOS信息端到端可互通，可协调，可互操作的问题，它应该建立在参于同一应用的各异构QOS系统可被管理的基础上，即用户的QOS要求可描述，各QOS系统的性能和资源可预测，QOS系统内和系统间的QOS可协商，异构资源可配置，和异构资源可控制的基础上。
