An economic life is a blend of competitive and monopoly elements.

For safety reasons, the spark tester's current output is limited to 4 to 6 milliamps.

为了安全起见 ﹐ 火花机的电流输出被限制在4~6毫安.

In addition, it must be able to supply short pulse currents of several 10 s of milliamperes.

另外, 它必须能够提供数10秒的毫安级的短脉冲电流.

Typically, this system will disconnect all non-grounded phases at trip level of 30 mA or higher.

典型地, 该系统会在30毫安或更高的触发级别下切断所有的未接地相.

If the same milliammeter is used to measure a voltage up to 10 V.

改装同一毫安计使能量度10V电压.
