查询词典 assumption

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。

First, under the assumption of a planar scene, the LDV image is globally warped according to a homography to generate the initial distortion correction.

首先，在平面场景的假设下，大位移视点图像通过单应矩阵进行全局变形得到初始的畸变校正。

In optimum design theory, many results have been obtained under the assumption of exactly correct response and homoscedasticity.

经典最优设计理论假定响应曲面为真，也即试验者所选用的模型是完全正确的。

In ordinary regression analysis with random effects, the homoscedasticity of random effects is a basic assumption.

在随机效应回归模型中，随机效应存在时随机效应方差齐性是一个基本假定，在这些假定下，方可进行常规的统计推断。

K. H. Roscoe and his fellows of Cambridge University established the first elastoplastic model of soils which is based on classical plastic theory in 1963. However, due to the complexity of soils, the models that based on the classical metal constitutive theory or its modification accounting on the nature of soils have still much limitation when used to express the soil mechanical behavior. For example, the Duncan-Chang's model based on the generalized Hooke's law can not express the dilatancy of the soils. The uniqueness assumption of the direction of the incremental plastic strain in the classical plastic constitutive theory is not in agreement with some soil experiments.

但由于土的复杂性，目前以传统的本构理论为基础考虑土的一些特性而建立的模型在反映土体的力学特性上还存在很大的局限性，如建立于广义虎克定律基础上的Duncan—Chang模型不能反映土的剪胀性，传统的塑性本构理论中认为塑性应变增量方向具有唯一性的假设与一些土体的试验结果不符合。

目前常用的冷连轧张力微分方程dt=E/Lν_b(i+1-ν_dτ是假设机架间的带钢具有均匀的断面，引用等断面直杆虎克定律导出的，故为等断面张力微分方程。

The rigid-plastic assumption simplifies the 1-D Burgers model and thus simplifies the calculation of plastic deformation.Such simplified 1-D Burgers model is extended to 3-D case as the usual treatment like 3-D Hooke's law.

利用刚塑性假定简化一维Burgers模型，从而简化了沥青路面的永久变形计算，据此假定将一维的沥青混合料Burgers模型推广至三维Burgers模型，类似于三维虎克定律。

One is a summary of recent research and the other is a model study in which various kinds of models based on Hotelling duopoly are established to analyze the roles played by model's assumption.

All these are based on the analysis of using Hotelling spatial differentiation model and the equilibrium theory of the game theory, and on the assumption that there is no collusion and monopoly between sellers.

但是，对信息技术投资力度大并使消费者搜索成本降低得更多的销售商，则可扩大市场占有率和提高市场竞争力，因此销售商具有投资激励。

He made the assumption that the electronic charge is numerically equal to the charge on a hydrogen ion.

他假定电子的电荷数与一氢离子的电荷数相等。
