In spite of the granular nature, soil has traditionally been modeled as a continuum. This continuum mechanics cannot get the precise solution while soil\'s nonlinear, discontinuous, large deformation, and strain localization behavior are considered. The discrete element method is based on discontinuum theory, and is pioneered by Cundall.

土是由多相介质组成的离散颗粒集合体，尽管研究者早已在土的散粒状属性上达成共识，但关于土体力学性质的研究还经常沿用连续介质力学方法，这种基于连续体小变形假设的方法在求解实际土体非线性、非连续、大变形、应变局部化问题时往往无法得到精确解答。

In order to study the airflow distribution of electrostatic precipitation more precisely, the Euler-LaGrange multiphase flow model was used for gas-solid flow numerical simulation.

为了更加精确地研究电除尘器入口气流分布特征，论文采用欧拉-拉格朗日多相流模型，对电除尘器内部气流分布进行了数值仿真。

Chapter 2: Blind parameter estimation of MPSK-DS signal is discussed.

第2章：对多相调制扩频信号的盲参数估计做了研究。

A kind of polyphase brushless exciter which has better property came into the world in recent years.

近年来一种性能较为优越的新型多相无刷励磁机问世，有关学者已对其运行状况进行了仿真和实验分析。

Based on the analysis of multiphase flow in vortex field,including the analysis of forces exerted on and the movement of droplets,the mechanism of vortex field coalescence was investigated.

在对旋流场内多相流的分析，包括分散液滴的受力和运动分析的基础上，研究了旋流聚结的机理，并通过试验验证了旋流场内聚结过程的存在，且发现在某一进料流量时聚结效果特别明显，即存在最佳进料流量或入口雷诺数。

Thus this topic has become of great interest in fluid mechanics research.

本文主要从事气粒多相流的大涡模拟研究。

The fundamental equations derived from these two models are different and they can not be converted from one to another.

各模型本身也存在一些缺陷。这些都是由于对多相流的随体导数不恰当运用引起的。

Besides this, the result of heterogeneous reacting effect is known obvious and special from which the product owns the faint scent smell like watermelon and its fusibility is between 80℃～120℃.

此外，由反应产品具有类似西瓜的清香味及熔程在80～120℃间可知，多相催化反应效果是明显且独特的。

A novel photocatalytic reactor, which can use sun light and graniform photocatalyst, was developed and evaluated. Hydraulics studies show that the actual mean residence time was approximately 1. 5 to 2 times greater than the theoretical mean residence time, which is of great advantage for degrading the pollutants in the reactor, and that the high reaction rate can be obtained by increasing the rotational speed.

设计了一种新型提升式圆盘多相光催化反应器(exalting round-platephotocatalytic reactor，ERPPR)，该反应器的主要特点是能够利用太阳光和粒状催化剂，通过对ERPPR水力学特性的研究发现，该反应器的实际平均水力停留时间约为理论平均停留时间的1.5到2倍，反应器内循环流量与提升桨转速成正比。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
