With the improvement of aviation technology , the controlled flight into terrain ( cfit ) accidents / instances result from human factor has become the main cause result in the air disaster 随着航空设备技术水平迅速提高，人为因素造成的可控飞行撞地cfit已经成为商用飞机机毁人亡的主要原因。
The flight safety is the permanent topic in the field of civil aviation . in order to prevent the controlled flight into terrain ( cfit ) accidents / instances from occurring , the aviation field studied the principles and equipments to avoid cfits 飞行安全是民航永恒的主题，可控飞行撞地和空中相撞是影响飞行安全的主要因素。为了减少可控飞行撞地和空中相撞的危险，航空界不断地进行了防撞理论和防撞设备的研究。
Now and again a hole gave the first sledge a jolt ; the next was jolted in just the same way , and the next , and the sledges followed one another , rudely breaking the iron - bound stillness . a hares track , a lot of tracks ! natashas voice rang out in the frost - bound air 前面的雪橇在行驶时碰到了一个坑洼，颠簸了一两下，后面的几辆雪橇也同样地碰到了坑洼，这几辆雪橇莽莽撞撞地打破禁锢着的寂静，开始拉开距离向前驶去。
So the aviation has installed the ground proximity warning system ( gpws ) on aircrafts since the middle of 1970s , and now is the enhance ground proximity warning system ( egpws ) . this paper describes the development , components , principle and the features of the communication navigation surveillance / air traffic management ( cns / atm ) , the traffic alert and collision avoidance system ( tcas ) , ground proximity warning system ( gpws ) , and / or the enhance ground proximity warning system ( egpws ) . it particularly discuses the positive effect that ads tcas / tcas2 and gpws / egpws take on cfit and middle _ air collision . integrating with the aircrafts type . the instances and the accidents . this paper analyzes the present problems in the field of air traffic management and the new technologies resolving these problems . so that we can improve the flight safety effectively 本文论述了新航行系统( cns atm ) 、空中交通警戒与防撞系统( tcas tcas2 )以及近地警告系统( gpws )和增强型近地警告系统( egpws )的发展、组成原理及其功能特点，着重讨论了自动相关监视( ads ) 、 tcas tcas2和gpws egpws在保证飞行安全、防止空中相撞和可控飞行撞地事故中所起的积极作用，并结合具体机型和事故事例，分析了事故发生的原因和目前存在的问题，对系统提出了进一步改进的可能，以期进一步保证飞行安全。
Amongst us a simpleton , possessed by the demon of hate or cupidity , who has an enemy to destroy , or some near relation to dispose of , goes straight to the grocer s or druggist s , gives a false name , which leads more easily to his detection than his real one , and under the pretext that the rats prevent him from sleeping , purchases five or six grammes of arsenic - if he is really a cunning fellow , he goes to five or six different druggists or grocers , and thereby becomes only five or six times more easily traced ; - then , when he has acquired his specific , he administers duly to his enemy , or near kinsman , a dose of arsenic which would make a mammoth or mastodon burst , and which , without rhyme or reason , makes his victim utter groans which alarm the entire neighborhood 在我们的人社会里，一个傻瓜要是心里怀有仇恨或动了贪念，想除掉一个仇人或除去一个近亲，他就会径自跑到杂货店或药房里，借口老鼠吵得他无法睡觉，要买五六克砒霜，他还会捏造一个假名字，而那却比真名字更容易被识破，假如他真是一个狡猾的家伙，他就会分别到五六家不同的药房或杂货店里去买，因此，当追踪线索的时候，就更容易了五六倍。然后，当他弄到他想要的东西以后，他就莽莽撞撞地给他的仇人或近亲吃一付砒霜，其份量之重，就是古代的巨象或恐吃了也会五脏崩裂的，就这样毫无意义地使他的受害者在那里呻吟，以致惊动了四邻。
