particle n. 1.颗粒,微粒;微量,极少量。 2.【物、数】粒子,质点。 3.【语法】虚词,不变词〔冠词、副词、介词、连接词、感叹词等〕;小品词 〔yes, no 等〕,词缀。 4.〔古语〕(文件中的)条,项。 5.【天主教】一小片圣饼。 He has not a particle of sense. 他一点脑子也没有。 fundamental [elementary] particles 【物理学】基本质点,基本粒子。
In addition , this capability allows study of particle - particle interactions at a variety of concentrations 另外,这种能力可以用于研究不同浓度条件下微粒之间的相互作用。
When adding a force / vortex field to an object , the object will get a small graphic indicating that there is a particle interaction connected to the object 当增加一个力/漩涡场到一个物体时,物体将会显示一个小的图标,弄表示物体连接了的一个粒子互相作用。
Certain discrepancy remain between the simulation results and the experiment results , not only caused by the turbulent model , but also by the simplification of the inlet boundary condition and the mesh generation . modeling gas - particles interaction flows is complex . in this thesis , gas - phase transport equations coupled with the gas - particle interaction are derived based on the dsm turbulent models to handle the interaction of momentum and kinetic energy of turbulence between the gas and particles 分离器内的固体颗粒运动采用涉及湍流扩散影响的随机轨道模型和确定轨道模型,同时在湍流模型中加入了颗粒影响的源项,在流场计算的基础上,模拟了不同直径的颗粒在分离器内的运动规律及颗粒分离效率,并同理论和实验得到的数据进行了比较。
Secondly , we present the set of nonlinear partial differential equations that describes the wave - particle interaction , by analyzing the output power spectrum , the limit cycle and chaotic oscillation of the radiation field in the traveling wave tube ( twt ) amplifier and the magnetically insulated transmission line oscillator ( milo ) are studied numerically , respectively 接着,在论文的第三章和第四章我们从导出了一组用于描述场和电子相互作用的非线性偏微分耦合方程组开始,利用频谱分析法,以行波管( twt )放大器和磁绝缘传输线振荡器( milo )为例,数值研究了o型器件和m型器件中场的极限环振荡和混沌行为。
