求翻译：16. 风管、动力管道应每隔25m就近与接地装置可靠接地一次。当管道采用普通法兰或螺栓连接，且中间存在有非导体隔离时，应采取跨接的接地措施。是什么意思？

16 Duct, Power Piping should be nearest the earth very well once every 25m. When the pipeline with common flange or bolted, and the middle there is a non-conductor isolation jumper grounding measures should be taken.

16. The duct, and power line should be every 25 M with ground nearby reliable ground. When the pipe in a common law jurisdiction, or bolt, and there are a non-conductor isolation should be taken when cross-docking of the earth.

16. Each the air hose, the power conduit should 25m nearby reliably earth with the grounding one time.When the pipeline uses the ordinary flange or the bold fastening, when also the middle existence has the non-conductor isolation, should adopt the cross-over the earth measure.

16. air ducts, power piping should be every 25m nearest grounding grounded again. When pipes bolted connections using LAN or common law, and when there is a non-conductor of the separation in the Middle, jumper grounding measures should be taken.
