The conditions that the parameters including high-priority token hold time and target token rotation time must satisfy are given .

给出了参数（包括高优先级令牌持有时间和低优先级目标 令牌 循环 时间）设置 时应满足的条件。

Furthermore schedule ability analysis of the high and low priority messages based on response time was presented . The principle of setting target token rotation time was also brought forward .

在此基础上，给出了 总线信息的消息 循环 时间、 令牌 循环 时间 和 总线 效率的计算方法，以及高、低优先级信息基于响应时间的可调度性分析，并给出了 总线目标 令牌 循环 时间的设定原则。
