With two diodes in parallel back to back, the circuit will provide protection regardless of the signal polarity.

由于两个二极管反向并联，所以此电路能够对任何极性的信号进行保护。

The sample test results from this synthetic test circuit are comparable with that acquired previously from a conventional Back-to-Back direct test circuit.

从合成试验回路所获得的样品试验结果和以前从传统的背靠背试验回路获得试验结果是相同的。

However, this synthetic test circuit offers several technical advantages and is superior to the Back-to-Back direct test circuit in terms of economy as well.

然而，这种合成试验回路更具有技术上的优势，并且在经济上也优于背靠背直接试验回路。

Everyone -- a lot of people, and certainly we made clear back in December that a political effort to short-circuit that process for ideological reasons would be counterproductive because a proper review that weighed all the important issues in this case could not be achieved in 60 days -- according to the State Department, which, again, runs this review process.
