离散

If a person attempt marriage in spite of a diriment impediment, not only is a mortal sin of disobedience committed, but the marriage is no marriage in the eyes of God and of the Church; and the contracting parties must separate from each other.

答： 使婚配无效的阻碍，无论是天主立的，或是圣教会定的，若犯了，不仅有背命的大罪，而且在天主及圣教会面前，婚配不算有效，必该离散；这样的阻碍共有十五条，共中容易遇到的，特别是岁数不足，或同外教人给婚。

The hierarchical model of HAVC has been set up, in which the discrete events has been used to dirve the system and the synthetic objects' control has been achieved.

本文建立了分层混成自动电压控制模型，采用离散事件作为驱动主体，实现了多目标优化协调控制。

He was one of the pioneers of the development of disaggregate travel-demand models and was the first to use and apply the logit model in the 1960s.

他是离散交通需求模型开发的先驱者之一，也是上世纪60年代将分类评定模型Logit Model运用于实践的第一人。

Based on RUM Logit model is Disaggregate Method in modern traffic planning theory .

LOGIT模型是基于最大效用原则的离散选择模型。由于其不需要很大的调查样本却同样能提供较准确的分类信息，它在交通方式划分研究上有着广泛的应用前景。

In order to bypass the difficulty of discretizing the boundary r or the Lebesgue discontinuous set Su in the Mumford-Shah model, we use an edge-detector function and a threshold value to induce a thin-belt where the image boundary lie in and displace the length of the boundary by the area of the thin-belt approximatively.

为避免在离散化Mumford-Shah模型中的边界Γ或Lebesgue不连续集S_u的困难，我们借助边界检测算子和门限值，确定图像边界所在的窄带区域，用窄带区域面积近似边界的长度。

In cases where an equivalent continuum cannot be defined, discontinuum network simulation is a viable alternative. Howerer, these models are very demanding in terms of computer resources, which restraints their application to engineering practice.

首先，提出了一种基于混合边界元—管流的改进的三维离散裂隙网络模型，并研究了提高模型计算能力的方法，使其可以具有更好的工程应用性。

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。

This makes more and more people pay more attention to studies and applications of numerical simulation in thermal recovery. In this research, we have developed a reliable mathematical model for thermal recovery, which takes a full consideration of the effect of viscos, gravitical and capillary forces on the three-phase flow of gas, water and oil, the effect of the temperature on the medium characteristics of liquid and solid, the phase equilibrium of gas-liquid in each component, heat transportation including connection, conduction and radiation as well as heat losses in both the overburn and underlying strata. In the space discreation of the mathematical model, we have proposed a new method based on the improvement of the conventional nine-points difference approximation, which has a higher difference accurancy.

本项研究以热力采油的主要机理为基础，充分考虑在粘性力、重力和毛管力作用下油水气三相流动，考虑温度对各种流体和固体介质物性的影响，考虑每一组分中汽液两相的相平衡，考虑热在地层中的传导、对流和辐射以及上下盖层的热损失，利用热力学第一定律、质量守恒定律和流体迁移定律，建立了正确可靠的注蒸汽数学模型；在对数学模型进行空间离散时，利用控制有限体积积分法，对以往的九点差分近似作了合理的改进，使其具有较高的差分近似精度：结果表明，该公式的近似精度要比以往文献中所给的九点差分近似精度高，可以认为，在油藏数值模拟中，如果遇到非均质情况，使用这种九点差分近似更合理。

Continuous and discrete system.

连续系统与离散系统。

State feedback catastrophe control method is introduced, deducing study is given both in continuous and discrete system, and simulation results confirm these methods.

提出了状态反馈突变控制法，对于连续系统和离散系统分别进行了推导，并给出了具体的仿真实例。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
