切换

The BCD2000 is packed with 2 state-of-the-art phono preamplifiers, one of which is switchable to a CD player.

BCD2000 还配有 2 个具有先进工艺水平的唱机前置放大器，其中 1 个前置放大器可被切换到 CD 播放机。

The principle of optical fiber photometer is analyzed.

文摘：本文就光纤光度仪的原理和设计中遇到的诸如光纤及光调制，光纤探头结构，光电转换电路设计，波长切换机构等问题进行了分析与讨论。

One interconnection was between the engine's electrical systems. They were wired so if the electrical system of one engine failed, the other would power both engines. This was not an automatic function, however. Switches on the instrument panel allowed the pilot to cause one engine's electrical system to operate both engines. Because of this interconnection, some weight was saved by virtue of using one full-size battery and a smaller back-up, rather than two full sized ones.

两台发动机之间唯一联系的就是发动机电子系统，如果一台发动机的电子系统出问题了，另外一台的电子系统可以驱动两台发动机，但是这种转换不是自动的，是需要飞行员在仪表板上通过开关切换；这样安排的好处是可以使用一个全尺寸的电源和一个小的备份电源，与两个全尺寸的电源相比减轻了不少重量。

It also shows why the need to use plain text mode and text mode and how to switch between HTML.

还说明为什么需要使用纯文本模式以及如何在纯文本模式和HTML 之间切换。

This lets you plug in up to three sources at once, complete with a separate audio connection for each, and switch between them as needed.

这可以让你插入多达三个来源一次，完成每一个单独的音频连接，它们之间切换需要。

Using value controlled all sealed non-service plumbic acid batteries, auto charging without man-watching.

采用阀控式全密封铅酸免维护电池，充电时无需人值守，监控电池状况自动切换充电方式，使用寿命长。

When thepolynomial has at least two simple real roots,sequences of critical values of timedelays corresponding to each positive root can be derived.

而当该多项式有二个及二个以上的简单正根时，稳定性切换次数主要取决于两方面：一是该多项式的正根的个数，二是该多项式的每个正根对应的临界时滞序列中相邻两项差的大小关系来确定。

This kind of technology can flex the application of optical amplifier so that a same adaptive amplifier can be used as a pre-amplifier, a boost amplifier as well as a line amplifier.

在光标记交换系统中，可满足由于路由切换导致的光功率损耗大范围动态变化的应用需求。

The line-tracking system and obstacle-avoiding system use the infrared photoelectric sensors to realize intelligent walking. The LED display system which through control the input and output of 74HC595's data, shows the prearrange face at 24×24LED matrix. Then, simulate the brow change by changing picture to get the function of changing faces.

机器人运动过程中，采用PWM技术和开环系统控制无刷直流电机的运行，实现机器人的行走控制；机器人的寻线及避障系统采用红外光电传感器，实现机器人的智能行走；LED显示系统中，通过编写程序实现对74HC595的数据输入输出控制，在24×24LED点阵上显示预置的面部表情，通过画面切换模拟人物表情变化，实现变脸功能。

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。
