The factors which effect on leakage dissolution characteristic and the leakage dissolution stability &durability of concrete have been discussed. 论述影响混凝土渗透溶蚀特性的因素，渗透溶蚀稳定性及混凝土渗透溶蚀耐久性。
Although the presence of fuel-rich boundary injection apparently degrades engine stability, it is generally necessary to enhance chamber wall endurance. 尽管富燃料边界喷射的存在显然降低了发动机的稳定性，但通常这是为增强室壁的耐久性所必需的。
