真空的

During water quenching of meltten these alloys in fused silica tubes, the icosahedral quasicrystal solidified first, then the decagonal quasicrystal, and finally the crystalline approximants.

将成分为〓〓的合金放在抽真空的石英玻璃管中熔融后水淬，二十面体准晶首先形成，接着是十重对称准晶，最后形成的是准晶的晶体近似相。

Only in the frictionless vacuum of a nonexistent abstract world can movement or change occur without that abrasive friction of conflict.

仅仅在一个不存在的无磨擦真空的抽象世界里，运动或变化才不会发生粗糙的磨擦和冲突。

I told him many years ago, it's very hostile," Kittinger said."You're in a vacuum, and your whole life is dependent on the pressure suit working properly.

我告诉他许多年以前，这么做非常危险，"基廷格说，"你处于真空的环境中，你的全部生命都仰仗气压服的表现。

In the vast space of relative vacuum mutuality 6×1055 macrocosm, the quantum of stable spatial measurement huge quantity hold in that.

在6×1055个宏观世界之间的相对真空的广袤空间中，巨量的稳定宇称量子在那里蕴藏。

In electronics, a vacuum tube or thermionic valve or just valve, is a device generally used to amplify, switch or otherwise modify, a signal by controlling the movement of electrons in an evacuated space.

真空管是一种电子设备，由抽真空的容器组成，它具有发射电子的阴极（旁热式是由灯丝加热，直热式则灯丝就是阴极）和工作时通常加上高压的阳极。阴极和阳极之间，自阴极算起，第一个电极称为栅极，再增加一个电极则称为帘栅极。

They are all sealed piston units and their vacuum capabilities are limited to several 10s of Torr.

他们都是密封活塞单位，其真空的能力是有限的几个10名的torr 。

Pascal's earliest work was in the natural and applied sciences where he made important contributions to the construction of mechanical calculators, the study of fluids, and clarified the concepts of pressure and vacuum by generalizing the work of Evangelista Torricelli.

帕斯卡最早研究自然科学和应用科学，对机械计算器的制造、流体研究作出了重大贡献，通过归纳托里拆利的研究，他阐明了压力和真空的概念。

At present, a large amount of experimental data on the masses of ground and excited states of baryons has been accumulated.

但是，由于源于中程和长程区域与QCD真空的复杂结构有关的非微扰效应，还不可能获得整个距离范围内的夸克-夸克相互作用势。

It is the velocity at which the corpuscles travel through empty space.

N： 在微粒说中光的速度具有完全确定的意义，那就是微粒通过真空的空间的速度。

This paper gives methods of determining the optimum vacuum of condenser that takes account of the save on cooling water, the methods can help reduce costs and environ.

文中提出一种考虑节水因素的凝汽器最佳真空的确定方法，为降低发电成本及减少环境污染提供了一项有效的途径。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
