This book deals with deterministic systems and does not include any analysis of stochastic phenomena . 本書不分析隨機現(xiàn)象,主要討論確定性系統(tǒng)。
In the first part of the thesis , we generalize the unified approach to the evolutionary random response problems of a deterministic system ( the unified approach in brief ) , to a random linear system in the following ways 論文前一部分將確定性系統(tǒng)中的統(tǒng)一解法,全面推廣到隨機線性系統(tǒng)中去,具體地作了三個方面的工作。
Under the illumination remark of chaos , this thesis raises the idea of modeling oceanic reverberation as an observation of a nonlinear deterministic system by the dynamics . the purpose is getting a new look to the reverberation 根據(jù)這一思想,本文提出混響的非線性動力學建模,即非線性確定性建模,從而給出認識混響過程的另外一個全新的角度。
By orthogonal polynomial approximation method , we first reduce the random system into its deterministic equivalent one , so the response problem of a random system can be transformed into that of a deterministic system 有關(guān)上述gegenbauer多項式方法在隨機振動問題中的應用,現(xiàn)有文獻中尚未見報道。上述三種方法都可以用于求解隨機結(jié)構(gòu)的演變隨機均方響應問題。
The numerical results from the phase portraits , the period - doubling bifurcation and the poincare sections show that external stochastic excitation always masks the regular motions of a deterministic system and plays a dissipative role to the motions of the system , which causes the chaotic motions of the system to arise easily , though the period - doubling bifurcation is delayed 系統(tǒng)的相圖、倍周期分岔圖以及龐加萊映射圖等方面的數(shù)值結(jié)果表明,外加隨機激勵的作用往往掩蓋原確定性系統(tǒng)內(nèi)在的規(guī)則運動,對原確定性系統(tǒng)的運動具有較典型的分散作用,可延緩系統(tǒng)的倍周期分岔,也可使得系統(tǒng)內(nèi)在隨機行為提前發(fā)生,即可使得系統(tǒng)更容易出現(xiàn)混沌運動。

In mathematics and physics, a deterministic system is a system in which no randomness is involved in the development of future states of the system.deterministic system - definition at The Internet Encyclopedia of Science A deterministic model will thus always produce the same output from a given starting condition or initial state.
