在弗兰克·索看来,目前使用的大多数夜视设备装着一大堆电子元件,需要几千伏特的工作电压。为了让画面更加逼真,夜视镜的镜头与镜头之间必须保持真空状态,因此整个装置比较沉重。
Most night vision devices today use massive amounts of electricity -- often several thousand volts, according to So -- and heavy, glass lenses that maintain a vacuum to make the night come alive.
把伏特表、安培表、欧姆表的功能集中在一个仪表内是比较方便的。
It is convenient to include the function of a voltage ammeter and ohmmeter within one instrument.
虽然收集到的数量会比较有限,但是几伏特的电压对一些小玩意来说已经够用了。
The amounts would be limited, but a few volts might be enough to power small gadgets.
和600伏特设计比较,800伏特准谐振反激变换器的电压频谱在1兆赫兹以下更高一点,在1兆赫兹以上开始变小。
As it can be seen the voltage spectrum of the 800v quasi resonant flyback is higher at frequencies below 1 MHz, and is getting lower above 1 MHz compared to both 600v designs.
一半的伏特加一半的酸甜混合物,再加入少量的酸果蔓汁以取色。用岩石杯是比较好的。
Half vodka half sweet and sour and a dash of cranberry juice for color. On the rocks is better.
