Turns out the size of the electric field is inversely proportional to the separation distance.

电场的大小和分离距离成反比。

The operating distance is the separation of an object from the active sensor surface at which a switching signal is produced.

经营的距离，是从积极的传感器表面上的一个开关信号分离产生的对象。

Besides, the effect of distance of two surfaces on mass transfer efficiency and separation efficiency is quite week whether taking inert partial pressure into consideration or not.

当残留惰性气体压力较低和不考虑其分压时，蒸发面和冷凝面间距对传质效率和分离效率的影响都不大。

It estimates more than 11% of the island's 68, 900 population has put their name to the petition which calls for a ban on commercial wind turbines in any Area of Outstanding Natural Beauty and a separation distance of at least 1.5km (0.9 miles) from housing.

And one driver of that trend, says Gregory Guldner, director of the Center for the Study of Long Distance Relationships, is the perception that technology reduces the emotional separation of distance.

In the specific case of maize, to ensure that seed stocks achieve 99.9% purity, a separation distance of 200 metres is required from any source of "contaminating" maize pollen.
