The article can be divided into following parts : first , introducing the development and existing situation of air - traffic service and aeronautics safety , directing the potential and great insidious danger caused by disco - ordination between air - traffic service and aeronautics safety and aeronautics development , analyzing the causes of accident . second , introducing the related theory of safety and safety systematic engineering and methods of analyzing accident . third , based on the above content , analyzing the factors that affect the safety of air - traffic safety management , especially the human factor 本文首先介绍了空中交通服务与航空安全的发展及现状，指明了空中交通服务与航空安全与航空发展不匹配所潜在的对国际民生的巨大隐患，并对发生的事故征候和事故进行了初步的原因分析；其次介绍了安全和安全系统工程的有关原理和事故分析的方法；第四章则在此基础上对影响空中交通安全管理的因素进行了详细的分析，特别是人为因素的分析；最后，引入了mort方法以提高空中交通安全管理的安全性。
The using of the analytical model of the mort and user " s manual can not only find out the defects and omissions in the existing safety management system , but also improve the safety situations , so that the safety management for the air - traffic can be raised to the modern level 本文建立了空中交通安全管理的mort图及用户手册。应用此mort分析模型，不但能够发现系统缺陷和疏忽，为事故和事故征候的处理提供有力的证据和决策支持，而且能够提高空中交通的安全管理水平。
Nice humanism spirit , good scientific spirit and great innovative spirit can enhance symptomatic reading method , while the enhancement of symptomatic reading method can promote the cultivation of humanism spirit , scientific spirit and innovative spirit . hence it is advantageous to the formation of a virtuous cycle of the students " development . we should make an effort to accelerate the formation of this virtuous cycle so that it can promote the development of students " individuality and implementation of the goals of quality education 良好的人文精神、科学精神和创新精神可以有利地强化学生的征候式阅读方式，而征候式阅读方式的强化则反过来促进了学生的人文精神、科学精神和创新精神的培养，由此形成了这样一个有利于学生发展的良性循环，我们应该尽力促使这一良性循环的形成，以促进学生的个性发展和素质教育目标落实。
These are the signs of the coming arctic winter : the color of the tundra changes as the water grasses turn brilliant red . the migratory birds gather in flocks along the coast and gradually drift southward . most of the birds that have spent the brief summer on the tundra now disappear , leaving only the golden eagle , the gyrfalcon , the ptarmigan , and the snowy owl to brave the sunless northern winter 这些都是北极地区冬季即将来临的征候：随着水草变成艳红色，北极苔原的颜色也改变了候鸟沿着海岸成群聚集，并逐渐南移在苔原度过短暂夏天的大部分鸟类现已消失，只剩下金鹰白隼松鸡和雪白色的猫头鹰来迎接这没有太阳的北极之冬。
Seller ' s market is transiting to buyer ' s market . by sep . 1998 , buyer ' s market has completely formed ; the average load rate of the power system is declining , and difference between apex and vale is becoming larger and larger ; power consumption increase rate in industry is dropping , and it is far lower than that of society power consumption 分析表明：从1997年开始，重庆电力资源短缺状况得到缓解，供需基本平衡，具备逐渐由卖方市场过渡到买方市场的征候,到98年的9月已完全形成买方市场；重庆电网年平均负荷率逐年下降，峰谷差逐年加大；工业用电量持续下降，且其增长速度远低于全社会用电量的增长速度，占全社会用电量的比例逐年下降。
