3、To further enhance efficiency the voltage drop across the tracking regulators has been minimized.
要進(jìn)一步提高效率，需最小化跟蹤穩(wěn)壓器過(guò)程中的壓降。

4、They also limit the voltage drop across the igniter during continuity testing.
他們也限制了壓降 * 的過(guò)程中的連續(xù)性測(cè)試。

5、Read the pressure drop across the valve with a Watts Series PG meter.
