An improved one - dimensional ca traffic model was proposed to describe the freeway traffic under the periodic boundary conditions. this model was based on the nasch model, it can describe stop - and - go traffic, which gives a better description of the phenomena observed on highways with a slow - to - start rule
在元胞自動機交通nasch模型和fi模型的基礎上，基於交通流中實際車輛的慢起動行為，進一步提出一種新的一維交通流元胞自動機模型，在臨界密度附近，存在著亞穩態和滯后現象。 -
Sometimes it is difficult to predict and calculate the periodic orbit, so the chaotic control technology based on washout filter is used to control chaotic phenomena of dc / dc converter
針對上述不足，本文採用了washout濾波器來控制dc / dc變換器中的混沌現象，模擬結果證明了該方法的有效性。 -
The delay can affect the existence and stability of solutions as well as leads to the periodic, quasi - periodic and more complex phenomena. so it is more difficult to study the partial differential equations with delay
時滯可影響方程解的存在性、穩定性，可導致周期、擬周期等更為復雜的現象，因而在研究上更加困難。 -
Detailed numerical studies are presented for the transitional dynamics of the steady - state motions of those systems with the variation of the excitation and the system parameters, with the illustrations given for rich nonlinear phenomena, such as the bifurcations of periodic vibro - impact motions and the chaotic vibro - impact motions. in chapter 5, the existence of the periodic vibro - impacts, as well as the corresponding stability is analyzed for an oblique - impact vibrating system composed of a spring - pendulum and an oscillator. when the system damping and the tangential friction
結果表明，在無阻尼、無摩擦的簡化情況下，周期斜碰撞振動運動具有嚴格的存在條件，並隨激勵參數的變化出現復雜的分叉和穩定性的反復切換；運動阻尼可在較大參數范圍內對非穩定運斜碰撞振動系統動力學研究（ 5 ） （ 6 ）動鎮定;相對而言，切向摩擦對系統穩態特徵的影響不大。 -
In 1860, schrodinger first put forward the concept " schrodinger equations " in quantum mechanics and since then, the study on schrodinger equations has never stopped, for the mathematical description of many physical phenomena belongs to the field of schrodinger equations, such as nonlinear optic, plasma physics, fluid mechanics etc. as for the form of schrodinger equations, linear schrodinger equations was gradually replaced by nonlinear schrodinger equations ; as for the methods of solving schrodinger equations, the modulus estimate of energy, the principle of contraction mapping, fourier transformation and harmonic analysis are used ; as for the space of the solutions, many people have worked on the problem in bounded domain, euclidean space of dimension n, periodic bounded conditions and mixed regions and they also combined it with the generalization from low dimension to high dimension
） dinger方程，如非線性光學、等離子物理、流體力學[ 21 ]等；在方程形式上，從線性schr （ ? ） dinger方程到非線性schr （ ? ） dinger方程；在處理方法上，用能量模估計、壓縮映象原理和fourier變換調和分析等；在方程解空間上，研究有界區域、 n維歐氏空間、周期性有界區域和混合區域等，並且結合從低維向高維推廣。
