Results ofweight loss in lab and field site show that corrosion rateof A3 steel can be accelerated flow of seawater, especially in the initial stage.
室内和实海挂片失重测试比较结果表明，海水流动能够加快A3钢在海水中的腐蚀速度，腐蚀初期尤其明显。

Cash flow indicator and social contribution rate have been added in the performance evaluation system. We will use of AHP to set up the weight and score.
A set of experimental system used to measure flow field of spiral separator is constructed, with the experimental data, such as the pressure and flowrateof gas and the weight of drained water etc.
