【摘要】 在冲击伤研究中,必须针对两种试验方式分别对致伤机理、耐受性和机体瞬时动力学响应等进行研究。只有这样才能得到近真实的研究结果。文中介绍了能够模拟爆炸波波形因素和满足动物冲击伤实验研究物理参数要求的BST-Ⅰ型生物激波管。它是国内第一台用于生物实验的激波管。文中有应用该管开口和端板的两种实验方式,选用51只成年雄性杂种狗作耐受性实验观察。对实验结果作了分析。更多还原

【Abstract】 The present paper introduces a biological shock tube which can simulate waveform factors as blast wave and satisfy the needs for the experimental study of animal blast injury. It is the first shock tube for biological study in China.The paper presents experimental results of tolerance of 51 male mongrel dogs in the tube with two end conditions opened or closed. The results may give some reference values for studies on prevention, diagnosis and treatment of blast injuries. The results indicate that it is necessity for separative studies on injury machanism, tolerance and dynamic response in the two experimental conditions. Only in this way will the results be comparable in the sense of reality.更多还原
