And this is what happens when you put together high and low power.

这就是你力量强大和微弱时会发生的事情。

But you're probably thinking, " Well, what about, you know, in countries where there's lower purchasing power? "

也许你会想，“嗯，你看，对于购买力比较弱的国家又会怎么样呢？”

It gives those low powered pulses enough time to actually heat the surface of the steel to the perfect temperature.

它给了那些低功脉冲够的时间来将钢的表面加热到完美的温度。

Another reason is because the filament has always been run at low power, just four or five watts.

另一个原因是灯丝一直以低功运行，仅为四或五瓦。

When factoring a trinomial where the leading coefficient isn't one, it must be written in descending order from highest power to lowest power.

对三项式进行因式分解时若首项系数不为1，必须先把各项按高次到低次重新排列。

Because we're using a low power, we can actually just heat the surface of the steel in order to obtain this black mark.

因为我使用的是低功，我上可以加热钢的表面来获得这个黑色标记。

Others have combined glass with solar cells that are thinner and smaller but they can have drawbacks like lower power efficiency and less transparency.

还有公司将玻璃与更薄更小的太阳能电池结合起来，这种产品也会有一些缺点，比如它的储电效和明度都比较低。

It's similar to the infrared used in TV remote controls, but TV remotes send the signal in many directions which is good for simple low power data communication.

它类似于电遥控器中使用的红外线，但电遥控器向多个方向发送信号，这有利于简单的低功耗数据通信。

Lastly, the T800 sports a low power short-range radar system which it can use to triangulate and locate the position of hidden snipers upon being hit- assuming it survives the initial hit.

最后，T800 配备了一个低功短程雷达系统， 它可以用来三角测量和定位被击中的隐藏狙击手的位置——假设它在最初的命中中幸存下来。
