可假定的

The comparison indicates the strain variety ratio of strain and that of interface layer are closed, the theory formula based on this assumption is more reasonable and can be applied in engineering practice.

几种基本假设中，假定光纤与中间层一起变形，二者应变变化率相近最为合理，在此基础上推导出的理论公式可应用于工程实际。

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

When G is not a commutative semitopological semigroup, Lau and Takahashi proved the ergodic theorem for right reversible semigroups of nonexpansive mappings by using the methods of invariant means.

而当G非交换时，Lau和Takahashi利用不变平均技巧，在假定G是右可逆，X具一致Frechet可微范数及RUC存在不变平均等条件下，给出了非扩张半群的遍历压缩定理。

With the aid of inverse Laplace transform, the main reliability indexes of the system such as system availability and reliability can be calculated.

假定每个部件仅有2种状态：工作或失效，那么系统的状态过程是一个时齐的离散的马尔可夫链，它可以产生1列微分方程，借助于拉普拉斯逆变换可计算出该模型的主要可靠性指标--系统的可用度及可靠度。

The computational results show that the assumptions of incompressible water and massless foundation can considerably simplify the complexity of equations and cut the amount of computation, but cause little errors.

计算结果分析表明：在高拱坝流固耦合动力分析中，水体不可压缩和无质量地基假定可显著地消减方程复杂度和计算工作量，但带来的数值误差较小。

We assert that quantity demanded can only decrease when price increases because (1) this assertion can bring us refutable implications and (2) the refutable implications coming from it are repeatedly confirmed by facts.

经济学假定「需求定律」是真确的，是因为这可(1)引伸出可被事实推翻的含意，更重要是(2)这些由需求定律引伸的含意不断被事实确认。

However, experiment indicate that the result of the detection method is inaccurate and anamorphic.

本文讨论了双板分动式侧滑台对轴间侧滑量的检测，在假定条件下，通过数学计算可求出轮间和轴间侧滑量，但实验结果却表明这种检测方法测量结果重复性差、失真较大。

In the CGE models discussed above, it is assumed that the service sectors are governed by perfect competition or large-group Dixit–Stiglitz monopolistic competition both before and after service trade liberalization.

在可计算一般均衡模型，讨论上述它假定服务行业均受完美的比赛，或大集团dixit -斯蒂格利茨垄断竞争前在服务贸易自由化。

On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.

单道锚杆支护结构计算分别采用静力平衡法及等值梁法，根据试算法插入深度t值需先进行假定墙的插入深度确定后来计算支撑力，为了安全起见，可按插入深度增大前的主动与被动土压力合力计算支撑力即 RA=EA-EP 式中：RA …………支撑力 EA …………主动土压力合力 EP …………被动土压力合力随之可求围护墙的弯矩分布，Mmax为剪力为零点的位置，等值梁法的计算略述。

They both have merits and shortcomings. The first one calculates simply, and has corresponding design code to follow about safety factor. But it has many errors because of many assumptions about seepage and deformation of rock abutment. And it is not convenient to optimize the arch dam shape because of dealing with arch dam and abutment separately.

两者各有优缺点：前者计算简单，安全指标有规范可循，但对坝肩岩体渗流和变形性质的假定过多，有一定误差，而且由于将坝身和坝肩分别看待，在作体型优化时很不方便。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
