following aircraft造句

• Wake vortex separation standards are used to prevent hazardous wake vortex encounters which mainly found in the final approach course within the airport termination zone . firstly, this paper analysis the mechanism of the vortex decay and research the influence on the safety of the flight; then . several different radar wake vortex separation standards are compared and some basic guidelines are developed to establish the future vortex standards . in addition, one kind of advance vortex classification for the civil airplane is proposed . secondly, an encounter hazard model which established for the following aircraft and a simple vortex decay model which mostly concern with the proceeding one are developed; and a safe separation model can be derived from the both . finally, through the simulation calculation, the correctness of the vortex classification of different types of aircrafts are tested and proved
  本课题对雷达管制条件下的最小尾流间隔标准进行了较为详细的分析和研究；首先对尾流的形成和消散机理以及尾流对飞行安全的影响做出了详细的分析，然后就目前实行的几种不同的最小尾流间隔标准进行了比较和分析，提出了相关的几条准则和一种改进的机型尾流分类标准；在这之后，采用理论分析和统计数据分析相结合的方法，建立了尾流危险遭遇基本模型和尾涡消散模型；并在此基础上对民用航空不同机型的尾流分类的合理性进行了计算和评估，为最小尾流间隔标准的确定和改进提供了初步的理论依据。
