On the basis of that , this dissertation put forward prioritization scheme for the airborne data bus system . meanwhile , the dissertation discusses the processing of the nonperiodic messages 在此基础上,提出了机载数据总线系统优化方案,讨论了对非周期消息的处理,最后给出了系统的调度方案。

Chaos theory is defined as the study of complex nonlinear dynamic systems . complex implies just that , nonlinear implies recursion and higher mathematical algorithms , and dynamic implies nonconstant and nonperiodic 混沌理论用于研究复杂非线性动态系统。复杂意谓它就是那样，非线性意谓递归和更高数学法则，而动态意谓非常数及非周期。

The method can be used in the measurement of periodic and nonperiodic signal . according to the high accuracy and fixed gate - time measurement method , based on the multiple period synchronization method , the high speed , high accuracy and continuous frequency measurement is accomplished 将其再与一种从多周期同步法发展而来的高精度、定闸门法相结合，从而实现了高速、高精度、连续频率测量，这非常适合非频率量的频率传感信号的测量。
