1·The results of laboratory accelerated weathering test and laser raman spectroscopy test show that, the property of ageing resistance and recoatability has greatfully been improved.

研究结果表明，改性后的纳米复合防护剂的耐老化性能以及重涂性能都有很明显的提高。

2·Usually, corrosion resistance of weathering steels is evaluated by the weight-loss method in an accelerated corrosion test.

通常利用加速腐蚀试验采用失重法表征耐候钢的耐大气腐蚀性能。

3·Outdoor weathering must be used to verify accelerated testing, and it is possible with the correct testing procedure to get meaningful data from an outdoor test in a short time frame.

使用正确的测试程序，户外暴露测试可以在较短的时间内获得较好的测试结果。
