The STE dominated by the intrusion of stratospheric air has been testified as a cause of ozone enhancement in upper troposphere over East Asia at the end of March 2001. This STE relates to the surface high moving southward, the upper cold eddy deepening and drifting eastward, the convergence of Subtropical Jet and Polar Front Jet associated with the cold front, the increasing temperature gradient near the jets, and the enhancing baroclinic instability.

天气诊断和动力分析表明，2001年3月底东亚地区几个臭氧探空测站探测到的对流层上层臭氧增加是以平流层空气下传为主的STE过程导致的，此过程与地面冷高压南下、高空冷涡加深东移的天气过程、以及冷锋推进引起的副热带急流和极锋急流的移动和汇合、急流附近的温度梯度加大、斜压不稳定增强等动力因素密切相关。

The result shows that, under the condition of the same thickness of material, increasing the number of layers properly can weaken the press, the cutting damage and the destruction due to extension, and lower the impact energy on the construction effectively. In particular, multi-layered protection construction is rather striking in its advantage of destruction-resistance under high stress and low impulse load.

结果表明，分层总厚度相等的条件下，适当增加分层数目可以有效减小冲击载荷对结构的压、剪损伤和拉伸破坏，降低结构所受的冲击能量，尤其对于高强度、持续时间短的脉冲载荷，多分层防护结构的抗毁伤能力优势更为明显。
