Any external shunt resistance across the voltage source will attenuate the measured voltage, as shown in Figure 2-3.

跨接在电压源上的任何外部分流电阻都会使测量的电压衰减，如图2 - 3所示。

Notice that this is a two-wire resistance measurement compared to using the electrometer voltmeter and external current source, which can make a four-wire measurement.

注意，这种测量方法是两线电阻测量，而使用静电计电压表和外部电流源则可以进行四线测量。

But retrograde Mercury backs into a conjunction with restrictive Saturn which is exact tomorrow morning, reminding us that external resistance is but a reflection of what we are feeling inside.

但是逆行的水星又与限制性的土星合相，确切地说是明天早上，提醒我们外部的阻力不过是我们内在感受的反应。

Nor can the resistance rely on external support as it used to when the West, South-East Asia and China united to oppose the Vietnamese occupation of Cambodia.

Plants have long been selected by nature and bred by humans or irradiated to create mutants with enhanced resistance or tolerance to external threats to their survival and productivity.

The current three-day surge is the strongest for the major averages in three months, but with resistance looming the potential for an external factor to spark another downturn (like, say, the Fed ending its QE2 program Thursday) is certainly important to keep in mind.
