At the same time, the ballistic limit curves of the Whipple shield in a velocity range from 0.5 km/s to 5.5 km/s was obtained. Comparing to the predicted curve from Christiansen ballistic limit equation, the experimental minimum critical projectile diameter is slightly greater than the prediction.

通过固定弹丸直径，改变弹丸撞击速度，寻找临界撞击速度的方法获得了铝合金Whipple防护结构在0.5～5.5 km/s撞击速度区间内的撞击极限曲线，并与由Christiansen撞击极限方程得到的撞击极限曲线进行了比较，结果表明，实验最小临界弹丸直径略大于预测值。

The inhibitive mechanism of sodium barbital for aluminium alloy in 3.5 % NaCl solution was investigated by pentidynamic polarization and SEM.

Spent solutions were finally drained into a mixing trough forneutralization, and subsequently, calcium or barium hydroxide and flocculant were added. Precipitate producedsuch as calcium or barium sulfate, calcium fluoride were separated, and recovered water was obtained after pu-rified by ion-exchange column.

分析了铝合金生产工艺中各步骤的化学成分，根据分析结果将常温脱脂、碱蚀、出光、阳极氧化和封孔等不满足生产要求的溶液排放至混合槽内进行中和，再加入氢氧化钠和絮凝剂分离沉淀后，经离子交换柱，得到的回收水可返回生产槽重复使用。

The theoretical minimum movement velocity for the sheet to be punched by laser shock wave s was deduced.

为了验证激光冲击波冲孔工艺的可行性，采用Nd玻璃高功率脉冲激光器在0.4mm厚锻铝合金板料上进行冲孔试验。
