假定

We also assume that a symmetric disconnection model is used, with the client going first.

我们也假定采用了对称的连接释放模型，并且由客户先释放连接。

The main objective of this dissertation was to develop methodologies with capability of engineering application for simulating flow in fractured rock using discontinuum models. The study work includes three parts. In the first part, numerical methodology of three-dimensional discrete fracture network model casing on hybrid BEM-channel was presented, and the technique for improve the model's computing efficiency was also studied. Firstly in this part, computer simulation methodology based on the Baechermodel for generating network of discrete fractures was presented, which includes the follow details: probability distributions of fracture density,orientation, trace length, size, and aperture and estimation of their statistical parameters; stochastic models of fracture network; Monte-Carlo's simulation method; numerical simulation procedure and technicality.

给出了离散裂隙网络模型所依据的基本假定；发展了基于Baecher模型的离散裂隙网络计算机随机生成技术：详细地推导了单裂隙渗流和多裂隙相交网络渗流的边界单元法公式，发展了离散裂隙网络中稳态渗流的边界元数值技术，并且讨论了相关的具体数值技术细节，如角点的处理方法，单元的自动剖分等：描述了混合边界元—管流模拟方法及其数值实现；研究了裂隙网络的简化方法，并针对裂隙网络边界元法的特点提出了一种改进的分块三角分解法。

A numerical method is gived to distinguish that a Petri net is a time charac-teristic nets or not.The time characteristics of transmit are discussed and the density formula of transmit is given. stochastic petri nets ; time characteristic ; distractive matte

一般情况下，随机Petri网现有的分析方法大多是假定变迁的发射时间服从负指数分布，然后将网标识过程等价于连续参数马尔可夫过程，然后利用求解马尔可夫过程的一套数学方法来分析Petri网的时间特

If this is true, the wage-goods equivalent of the existing money-wage is not an accurate indication of the marginal disutility of labour, and the second postulate does not hold good.

如果确实如此，等值于现行货币工资的工资品就不能准确地表示劳动的边际负效用，于是第二个假定也就无法成立。

The postulate that there is a tendency for the real wage to come to equality with the marginal disutility of labour clearly presumes that labour itself is in a position to decide the real wage for which it works, though not the quantity of employment forthcoming at this wage.

实际工资趋向等值于劳动的边际负效用这一假定显然暗含着这样的推论：劳动者自己能够决定他愿意为之工作的实际工资，尽管他不能决定在这一工资水平下的就业量。

It follows from this definition that the equality of the real wage to the marginal disutility of employment presupposed by the second postulate, realistically interpreted, corresponds to the absence of "Involuntary" unemployment.

由此定义可以推论出，第二条假定所暗含的实际工资等于就业量边际负效用，就其现实意义而言，相当于不存在"非自愿"失业情形。

By the time Timothy Dwight's best student, Nathaniel W Taylor (1786 - 1858), assumed his position as professor of theology at Yale Divinity School in 1822, the movement from Edwards's specific convictions was very pronounced.

由时间蒂莫西德怀特最好的学生，纳撒尼尔瓦特泰勒（ 1786 -1 858），假定他的立场，作为教授神学在耶鲁大学神学院在1 822年，该运动从爱德华兹的具体定罪是非常突出。

If doesn't then it will be assumed that this is a client-side DOM id.

如果没有那么将假定这是一个客户端的DOM ID。

Based on dynamic equilibrium equations of three-dimensional elasticity, a state equation was established for orthotropic foundation plates using double Fourier series, in which no assumption about stress or displacement modes was made. Analytical solutions and frequency equations of unified formulas were presented for thin and thick laminated foundation plates.

从三维弹性力学动力平衡方程入手，抛弃应力或位移模式的人为假定，利用Fourier双重级数，建立了正交各向异性地基板的状态方程，并分别给出了地基上任意层厚薄板静力问题的统一解析式和动力问题的频率方程。

In order to research its natural circulation, the downcomer part and the riser part is distinguished, where there are no mass and energy transferred between them.

该模型为体现其自然循环的特性，将下降段与上升段区分开，并假定两者之间不存在质量和能量的交换。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
