采用投样试验的方法，对未镀膜和镀保护膜滤光片在实验室加速模拟试验及海南万宁亚热带海洋性气候环境进行试验，通过对两种试验环境的腐蚀速率和表面形貌进行观察、分析和研究，得到两种试验环境条件下的的腐蚀特性，对腐蚀机理进行了初步分析。

The method of sample test, corrosion properties of green filter were investigated by experiment in the laboratory and Hainan Waning subtropical oceanic climate environment. The green filter includes both uncoated and coated protective coatings. The microphotograph and corrosion rate of two kinds of test environments are analyzed and studied, and the corrosion characteristics of two kinds of test environmental conditions are obtained. Preliminary corrosion mechanism was analyzed.
