电子管

The EQ-2 boasts two channels of fully parametric 4 band valve equalisation - which in conjunction with variable high and low cut filters offers unlimited control of any audio source.

EQ-2具有2通道全参数4段电子管均衡，联合可变的高和低频修剪滤波为任何音频输入提供无限的控制。

Argon provides an inert gas shield in welding and brazing, in lightbulbs and lasers, in Geiger counter s, and in the production and fabrication of certain metals.

氩是以液态空气分馏法大规模分离制备的，已用于为电灯泡、电子管和盖格计数器充气。

This distinction was important because the flow of output-valve grid current in AB2 made the design of the previous stage much more difficult.

这一变化很重要，因为在AB2里输出电子管栅极电流的流动使到前级的设计更加困难。

The residual gas pressure in an electron tube can be measured when the tube itself is operated as a hot cathode ionization gauge.Usually,its sensitivity K is determined by the method of gauge calibration.In this paper,author try to determine the sensitivity K by ca- lculation.The formulae for this purpose have be found out,and are used for both plate and cylindrical electrode systems.

把电子管接成热阴极电离计的工作形式，用来测量管内残气压强时，其灵敏度如何计算的问题在本文中作了讨论，给出了平板形电极系统和圆柱形电极系统的灵敏度解析式，对式中各量的计算作了详细介绍；并指出四极管中电子在电离区的平均渡越次数的表示式与三极管中的完全不同。

When the temperature of the modified Mo-grids is kept at 650 ℃, the modified Mo-grids' electron emission can not be detected with microammeter after 1000h life-span.

将样品进行电子管模拟栅发射试验，栅极温度为 650℃，试验 1000h以上基本无栅发射电流，可以提高栅控管的可靠性和寿命。

Excited by the current, the mercury atoms emit ultraviolet light, which bombards the phosphor coating on the inside of the tube.

被电流激活后，汞原子发出紫外光，轰击被覆在电子管内部的磷。

This allows small amount of gas to the metal tube for you to ignite the pilot light.

打开金属盒子下面的金属仪表板，找一下能不能发现指示灯（通常在燃烧炉旁边的一个小金属壳的电子管的末端），如果指示灯不亮，尝试第六步。

Then,in the early 1940s, John Mauchly and J.Presper Eckert,Jr.,of the University of Pennsylavania designed and built a vacuum tube computer,which they called the electronic numerical inegrator and calculator;it was completed in 1945 and installedat Aberdeen Proving Ground,Maryland. ENIAC used 18000 electron tubes,which required tremendous amounts of power;its failure rate wa high and it was difficult to program because a plugboard was required.

那么，在20世纪40年代初，约翰mauchlyj.presperEckert先生和霍尔特，该大学设计建造了pennsylavania真空管计算机，它们被称为电子计算器、数值inegrator；这是1945年建成并installedat马里兰州的阿伯丁。eniac使用18000电子管，这需要庞大的权力；它的失败率偏高，难以以佤节目因为插件需要。

Eventually we found a run down prefab with tube amps and a disused pool table.

最后，我们找到了一个拥有电子管扩音器和废弃台球桌的破旧活动房屋。

An electrode used in certain electron tubes to provide secondary emission.

从电子管中产生出一门格外强劲而短暂的战时工业。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
