- free particle model 自由质点模型
- The latter is called the "eigenstate" of the property being measured.A concrete example will be useful here. Let us consider a free particle. 后者也称作被测特性的“特征态”。这里将用一个具体例子。让我们认为一个自由粒子。
- A discrete particle model of a gas fluidized bed with particle size distribution has been developed. 建立了适合描述宽筛分流化床气固两相流动结构的离散颗粒模型。
- In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum. 我们以自由粒子为例，找到既有位置又有动量的波函数是不可能产生的。
- That is, one in which a free particle travels in a straight line (or more generally a geodesic) at constant speed, or is at rest. 还是觉得您就是可以自己定义一个惯性系？当然了，拿张纸一画是怎么都可以的哈，就是画着头晕些。
- Eulerian multiphase model combined with discrete particle model has been developed and proposed for investigate particle mixing. 提出并实践了将欧拉多相流模型和离散颗粒模型结合起来，研究颗粒的混合。
- Based on the Eulerian treatment of particle model, a particle-particle collision model involving turbulence enhancement due to a strong particle influence was founded. 摘要基于颗粒相欧拉模型，建立了考虑大颗粒对湍流增强作用的颗粒碰撞模型。

- For example, the free particle in our previous example will usually have a wavefunction that is a wave packet centered around some mean position x0, neither an eigenstate of position nor of momentum. 例如，在早先例子中的三个粒子将通常具有波包中心附近是某些所谓的位置x0的波函数，既不是位置特征值也不是动量特征值。
- The particle model is employed to study the coal devolatilization, the release of volatile fuel-nitrogen, formation of HCN and the subsequent conversion to NO during the devolatilization process. 采用数值模型研究了煤热解、燃烧过程中挥发分氮的析出、中间含氮产物HCN的生成以及转变为NO的过程.
- Comparing the numerical results with the exact solutions for the free particle case, we showed that the CESE method had excellent results in simulating the variation of the wave function. 数值解与自由粒子之解析解比较显示，时空守恒法模拟变化剧烈的机率分布具有相当精确的结果；
