Atmospherical plasma jet carries to the surface modification of tungsten oxide nanorod. The results showed that the modified use of plasma gas (O2), in the same distance to increase deal with test-chip of the surface then there is the formation of small particles with the trend, and in the higher distance to some deal with test-chip of the trend of the formation of small particles lower. N2 was more significant than that of Ar plasma for surface modification, and the test piece is somewhat part of the surface nano-rods box integration with the formation of small particle side of the box there is scheduling a clear rod-like.

本研究应用常压低温电浆设备对氧化钨奈米棒进行表面处理，其改质结果显示使用电浆气（O2）下，在一样的高度距离下随了处理次数的增多，试片表面随之融合一起有形成小颗粒的趋势，且在一样的次数下随了距离高度越高其形成小颗粒的趋势越低；在使用电浆气体为N2与Ar下，电浆气体N2比Ar有较大幅度的电浆表面处理，且试片表面有些许部分奈米棒融合一起形成小方块颗粒其方块颗粒侧边有明显的棒状排立。

From the experiment results,it is concerned that the thin film was composed of many small particles(most of them was with a size between 20 and 30 nm)uniformly deposited and intervein on the substrate surface. Some large particles were tightly embedded into the thin film.The deposition rate increased by increasing the precursor flow rate and the discharge power.
