摘 要: | 本研究采用激波管,探讨了发泡镍对肺冲击伤的防护效果和防护机理。结果表明,发泡镍可明显减轻肺冲击伤的程度,降低死亡率。发泡镍的防护作用可能与其降低冲击波超压峰值、延长正压上升时间和缩短正压作用时间有关。结果提示发泡镍是一种较为理想的冲击伤防护材料。

PROTECTIVE EFFCT OF FOAMY METALLIC NICKEL ON LUNGS OF DOGS FROM BLAST INJURY |
| |
Abstract: | The protective effects of foamy metallic nickel (Ni) on the lungs of 16 dogs from blast injury induced by the biological shock tube and its mechanisms were studied. The results showed that protected by the foamy metallic Ni, the injurious degree of lungs and the mortality of the dogs decreased significantly, compared with those of unprotected dogs. It was thought that the foamy metallic Ni could decrease the peak value of the superpressure, reduce the blast time of positive pressure and retard the rising time of positive pressure of the blast wave. It was suggested that the foamy metallic Ni was an ideal protective material of lungs against the blast wave. |
