极限

Center sill and body bolster are important component of gondola car, and it is a big threat to the safety operation when the component occurs fracture, so the fatigue limit with high confidence level and high reliability must be gained first.

中梁和枕梁是敞车的重要组件，如果该组件发生断裂，会对行车安全构成极大威胁，所以首先要得到该组件具有高置信度、高可靠度的疲劳极限。

Richard Gowan, of New York University, notes that sub-Saharan countries have many wars but hardly any helicopters; traditional UN troop contributors, such as India, are close to the limit of what they can supply; some Western countries such as America and Britain are overstretched in Iraq and Afghanistan; while others are reluctant to become involved in fighting, be it counter-insurgency or tough peacekeeping.

纽约大学的理查德·高万指出，撒哈拉以南地区发生了许多战争，但几乎没有直升机；联合国维和部队的传统派出国，如印度，已接近其所能供应的极限；而美英等一些西方国家则在伊拉克和阿富汗过度伸展；其它国家则不愿卷入战斗，无论是反叛乱还是困难重重的维和行动。

This paper presents two methods to analyze the stability of a gravity dam and its foundation.

论文提出2种分析重力坝和坝基稳定的方法：一种是基于刚体极限平衡原理的直接分析方法，它将坝体和岩基作为不变形的刚体，利用该方法可直接计算出可能滑动面的安全因数；另一种是基于弹塑性理论的间接分析方法，它采用非线性有限元方法分析大坝和坝基的应力和变形。

In the meantime I continue to search for more of myself on solid and level ground.

同时，我也继续在坚实的水平地面上寻找自己的极限。

By a large amount of computation and analysis, a practicable partial coefficient design expression based on probabilistic limit states design is proposed, and a group of optimal partial coefficients are obtained.

为便于工程应用，在进行了大量分析计算之后，本文建议了基于位移的概率极限状态分项系数设计表达式，并确定了其中的分项系数。

Firstly, We have derived the reasonable dissociation limits for the O_2 molecularbased on the general principle of Atomic and Molecular Reaction and the grouptheoretical derivation of molecular electronic states.

首先，在原子分子反应静力学基础上，根据分子电子状态构造群论原理确定出了O_2分子基态X~3Σ_g~-和激发态b~1Σ_g~+合理的离解极限。

For that reason, I would guesstimate that 25% of this additional power is simply wasted in generating air bubbles around the blades. That being the case, then at a Trial Displacement of 53,900 tons, a tad over 34 knots would appear to be a top number. For a Light Ship Displacement of 51,000 tons, 36 knots would seem to be possible.

因此，我猜想在这样的情况下我们所增加的动力中将有25%会被空泡白白浪费掉、在这样的情况下，于53900吨的公试排水量下，34节的航速将会成为其极限航速、而对于轻载51000吨的情况下，36节的航速将会是可能的。

In this modification we plan to use the full extent of Half-Life 2's physics for ultimate game play.

在这种修改，我们计划充分利用程度半条命2的物理极限的游戏。

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。
