Typical accident-causing" theories includes Heinrich" s Domino" s theory, its development by Bird, Adams and other people, progress of which is that it is deficiencies of management system that are the root cause in accident causation sequence. This is author" s idea resource and main method to produce the water traffic accident-causing theory . in addition, uncontrolled transferring of energy theory, applies widely in safety management scheme for water traffic; human error accident model can be used to analyze causes of collision accident and to take preventive measures; perturbation theory and multilinear event sequencing method is a very useful investigation method to water traffic accidents. All of these theories have contributed to the development of water traffic accident-causing theory. As to orbit intersecting theory, the paper thinks it extension of Domino s theory, although it exists independently.

The frequency offset may be caused by many sources, Doppler shift or local oscillator error, for example.

这种频率偏移可能是由多个信源引起，例如多普勒频移或本机振荡器误差。

A country squire and his fat wife occupied the tapestried chamber; merry girls scampered up and down the long passages, and young men stared out of the latticed windows watching for southerly winds and cloudy skies; there was not an empty stall in the roomy old stables; an extempore forge had been set up in the yard for the shoeing of hunters; yelping dogs made the place noisy with their perpetual clamour; strange servants horded together on the garret story; and every little casement hidden away under some pointed gable, and every dormer window in the quaint old roof, glimmered upon the winter's night with its separate taper, till, coming suddenly upon Audley Court, the benighted stranger, misled by the light and noise, and bustle of the place, might have easily fallen into young Marlowe's error, and have mistaken the hospitable mansion for a good, old-fashioned inn, such as have faded from this earth since the last mail coach and prancing tits took their last melancholy journey to the knacker's yard.

一个乡绅及其肥胖的妻子住进了挂毯室；兴高采烈的小姑娘在长长的走廊里跳跳蹦蹦，来来去去；年轻的男子从花格窗里向外张望，守候着南风和多云的天空；宽敞的老马厩里没有一间分隔栏是空的了；院子里建起了临时的锻炉，准备给打猎的马儿钉蹄铁；猜猜而吠的狗儿用它们的永远不断的吠声把这个地方弄得喧闹嘈杂；奇里古怪的仆役们成群地聚集在顶楼上；隐藏在尖尖的三角屋顶下面的每一个小窗扉里，离奇古老的屋顶下的每一个老虎窗里，各自在冬夜里闪烁着烛光；夜间行走的陌生人，突然之间遇到奥德利庄院府邸，被这个地方的灯光、声音和熙熙攘攘所迷惑，很可能轻易地重蹈年轻的马洛的覆辙，把好客的府邸当作一个优秀的老式旅馆。自从最后一辆邮车及其腾跃的驽马作了最后一次郁郁不乐的旅行，进入收购废旧车船和无用牲口的商人的院子以来，这样的老式旅馆早已在这大地上消失无遗了。

The main works in this paper are as follows:(1). In this thesis, a new method, continuous linearization model, is constructed for the non-linear dynamic systems. The precision Duhamel integration solution for the linearization equation is also given from the theory of linear differential equation.
