穿透技术，多指NAT穿透技术，NAT,即Networ Address Translation，可译为网络地址转换或网络地址翻译。
注意：对于检测球墨铸铁中的缺陷来说，穿透技术的灵敏度不够，只有在特殊情况下使用该技术。
NOTE the transmission technique has insufficient sensitivity to detect the discontinuities found in spheroidal graphite cast iron castings and is used in exceptional cases only.
尽管该技术提供的速度快于移动网络，但其消耗的电量也更大，而且需要更多的基站才能达到覆盖率或是穿透建筑物的墙壁。
Although it offers faster speeds than mobile networks, it consumes more battery power and requires more base stations to achieve coverage and penetrate building walls.
关于那些掩盖住的成就，今天显露出的那些技术，例如穿透墙壁的雷达，机场犯罪意图探测器，以及盲人用的电子视力。
Add to those covered up achievements the recently revealed technologies such as through the wall radar, airport criminal intent detectors, and electronic sight for the blind.
