It does so by measuring the signal without drawing current, using “high impedance” sensors.
它使用“高阻抗”传感器来测量信号，而不是制图电流。
This is partly why the issue of “impedance mismatch” appears so important to a lot of OO people.
这就是为何“阻抗失谐”问题对于许多 OO 人员来说显得如此重要的部分原因。
If using a bioelectrical impedance scale, be sure to measure under the same circumstances each time. Hydration, food intake and skin temperature can affect body fat measurements.
如果是使用生物阻抗电子秤，确认每次是在同样的条件下。水和作用，吸入的食物和皮肤温度能过影响体脂的测量。

Even with distributed elements of what appears t be a miniature LOG PERIODIC antenna will have some difficulties with proper impedance matching, ohmic losses and inductance issues to say the least.

Planners assigned "impedance" values to points in the network.

Since most commercial (COTS) devices for the radio communications industry are normally 50 ohms intrinsic impedance, there will be problems with proper matching of the main power amplifier and the receiver front end.
