In the homogeneous model, the function of tendons is assumed to be uniform in some approximated way in order to form an equivalent homogeneous material within concrete. The formulation of the homogeneous model is same with that of general FEM for common continuum, let alone the elastic matrix being resultant of that of tendon and concrete. The computation is simple, but the approximate assumption makes this method cannot be generalized, because it only represents the constitution and function of tendons in such a rough way, that the numerical results are inaccurate. In the combined model, the function of tendon is considered by the stiffness matrix with rod element, then add it into the stiffness matrix of concrete by a rational way.

均匀类单元是设想将钢筋均匀弥散于整个单元中，使其成为一种连续均匀材料单元，这种单元的与一般有限元的单元刚度矩阵推导过程一样，只不过其弹性矩阵由混凝土和钢筋两部迭加而成的，此类单元刚阵计算简明而又不会扩大计算规模，但均匀弥散只是为计算简单而作一种假想，不贴近单元构造实际，也不符合实际作用效果。

There are three problems that should be deliberated when constructing a typical distributed virtual environment: 1 the representation of complex model in virtual environment, usually there are many entities and data in environment that should be recognized carefully. 2 the network communication, update and synchronal information is needed for variable entities are distributed in different computers linked by network. 3 the controlling of participant's behavior.

一是复杂模型的表达，通常这样的系统中包含复杂的较大规模的场景数据以及为数众多的实体，需要对这些实体加以组织；二是网络通信，由于环境中存在诸多可变因素，需要通知其它节点机做相应的刷新和同步，同时，分布的计算单元之间也需要交换消息或数据；三是参与者行为的控制。

In the SAWH model, the watershed is divided into model computation units according to topograph, and the MCU is then partitioned to several sub-regions according to land use, the heterogeneity of soil hydraulic conductivity and micro topograph is descriped by propobility density function and incorporated into the upscaled equations.

模型中流域下垫面特性的宏观不均匀性通过流域划分和模型计算单元内分区进行考虑，土壤饱和导水率和地形的微观不均匀性通过概率密度函数进行描述。

The distribution of stress, strain rate and energy dissipating coefficiency has been calculated.

This paper, however, proposes a countyscope gravity model to present the smallscale population migrations, using separated resident areas as basic calculation units.

在GIS的支持下，提出构建县域人口迁移引力模型，选择县域内独立的居民区片为计算单元来评价乡镇的人口吸引潜力和人口最大可能迁移目的地分布。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
