逃逸速度

Auxiliary engine operable, but incapable of escape velocity.

辅助引擎可操作，但无法加速到逃逸速度。

In Michell's theory, the escape velocity equals the speed of light , but it would still, for example, be theoretically possible to hoist an object out of a black hole using a rope .

在米切尔理论里，逃逸速度等于光速，只是它静止，例如理论上可能使用一条绳索从黑洞里提取一个物体。

Igneous electricity flue gas takes off saltpetre system whether achieve take off saltpetre rate and low ammonia gas high to escape rate, depend on greatly the flue gas is medium nitrogen oxide before entering saltpetre reactor and reducer ammonia gas blend even degree and flue gas speed to distributing.

梗概： 火电烟气脱硝系统能否达到高脱硝率和低氨气逃逸率，很大程度上取决于进入脱硝反应器之前烟气中的氮氧化物和还原剂氨气混合均匀程度和烟气速度分布。

The results show that the porosity of the membrane prepared by ScCO_2 induced phase separation is higher than that prepared by conventional method;the membrane structures are significantly influenced by the process parameters;compared with the conventional immersion precipitation phase inversion,ScCO_2 induced phase separation process can effectively avoid the formation of macrovoids at suitable operating conditions;during depressurization process,the great differences in the effect of depressurization time on membranes structure for various polymer materials result from that the speed of CO_2 gaseous nuclei escaping from membrane substrate can not keep the pace with the outer depressurization rate.(2) The tendency that the interaction parameters affect the binodal curve position is illustrated by changing the interaction parameters in reasonable ranges.

研究结果表明：与传统方法相比，采用ScCO_2诱导相转化法可获得更高的膜孔隙率；通过改变操作参数可对膜的结构进行调控，且操作参数对膜结构的影响与铸膜体系的自身性质也紧密相关；在适宜的操作条件下，ScCO_2诱导相转化法能有效避免采用传统的浸入沉淀相转化法制膜时易出现的大空腔结构；泄压过程中CO_2气核从聚合物膜基体中逃逸的速度能否与膜基体外部的泄压速度保持同步，是泄压时间对不同材质膜结构影响截然不同的根源所在。

The flow zone starts from the mid plateau, goes clockwise around the Eastern Himalayan Syntaxis, and ends at the southeast corner of the plateau with a fan-like front, which implies that the flow zone could be attributed to the escape of highly plastic upper crust material driven by gravitational buoyancy and lateral compression.

这一流滑带的前缘速度场在青藏高原东南角呈现出典型的扇形发散特征，表明整个流滑带可能起因于高塑性上地壳物质在挤压和重力共同作用下的连续性侧向逃逸。

So in principle it is possible that escape velocity as defined above -- i.e., population escape velocity -- could be achieved by rapid and sustained improvements in our ability to keep frailer and frailer people alive.

所以，从原则上说，可能上述界定的逃逸速度可以因我们能力的迅速而持续改善，使越来越虚弱人们保持存活。

Simulation results show that LELS and DELS yield faster convergence and better global optimization ability than standard evolution strategies; moreover, DELS also leads to better escaping capacity. Finally, limitations of the work as well as the future study are discussed.

在仿真试验中应用8个标准测试函数进行测试，结果表明此类算法具有较好的全局优化能力和较快的收敛速度，其中DELS的逃逸能力更强。

Data from existing X-ray satellites that show images of gas whizzing about black holes at close to the speed of light hint that time slows as the gas plunges into the zone from which escape is impossible.

从现有的X射线卫星传回的数据显示，气体以接近光速的速度呼啸着被吸入黑洞，这暗示当气体进入这个不可逃逸的空间时，时间慢了下来。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

设计师们为女妖战机量身打造了一套经济型双涡轮喷射引擎，因为作为只在行星大气层内作战的飞行器，其并不需要高性能的引擎来达到在既定轨道战斗所需的能量以及逃逸时所需的速度。

As a planetary craft, the banshee wouldn't need high-powered engines to achieve escape velocity and fight in orbit, so instead technicians fitted it with economical twin turbofans.

作为低轨道战机，女妖战机不需要大功率发动机用以达到逃逸速度，并保持轨道高度

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
