To realize the high efficiency of dernisting, thenew type cathode wires and anode tubes with superperformance were developed for increasing the current density and field intensity.

现除雾高效化，关键在于研制高性型阴极线和阳极管，高电流密和电场。

At the end of the experiment, a defogger automatically cleans the inside of the testing chamber for specimen.

验完成后，具有全自动除雾装置，可清晰观察验室内之试品。
