To simply thd research process, they isolate the individual objec from its surroundings, and describe its performance in thd time and space domain with linear continuous-variable epuations, arriving at a deterministic analysis, such as Newton's Second Law of Motion and the Epuation of Moving Body.

为了简化研究工作，先把研究对象孤立起来，使之从其所处环境中分离出来，再把它的性能用线性连续数学公式在其所处时空领域中进行描述，得到确定性的分析，例如牛顿的力学定律、运动的方程式等。

This make it difficult to know the essence of fluidized beds. In order to viewthe motion behavior of a single particle in a fluidized bed in a reasonable cost, thegas-solid flow in a fluidized bed is modeled by a combined approach of discrete particlemethod and computational fluid dynamics, in which the motion ofindividual Particles is obtained by solving Newton\'s second law of motion and gas flowby the Navier-Stokes equation based on the concept of local average.

为了用数值模拟方法来弥补传统实验方法的不足，达到从单个颗粒的尺度上来研究流化床中颗粒的运动和气体流场的剧烈变化情况的目的，本论文建立了基于用Newton第二定律计算单个颗粒运动轨迹的离散颗粒法和基于区域平均值的计算流体动力学方法的数学模型的建立和求解过程；并依据Newton第三定律建立了DPM模型和CFD模型的耦合模型，编写和调试了DPM和CFD的耦合程序。

Morse potential function was employed to describe interaction forces, and coupling followed Newton's second law of motion. A Gear's predictor-corrector algorithm was used to calculate molecular positions, velocities and accelerations at every time step.

A two-way ANOVA and a linear regression method are used to analyze the data collected from the experiments. The results show the stance is the primary factor affecting the attack-time and the larger the momentum generated by the tester, the shorter the attack- time for both jab and reverse punch. The estimated attack-time based on Newton's second law of motion is in the same order of experimental findings.
