“polarization pl”簡單造句，polarization pl造句子

The second research of the thesis is to design a double-patterns four-arm plane spiral antenna with the background of wideband circular polarization plane antenna's technology.

The results of measurements on paste type R20 battery showed that Zn electrode polarization played an important role on the sharp drop of cell voltage near the end of the discharge.

For the two operating frequencies of the proposed antenna, the same polarization planes and broadside radiation patterns are obtained.

The tricritical point in the temperature-polarization plane is obtained.
