摘　　要：为了确定平阴尿塔的爆炸原因,在进行全塔物料衡算的基础上,分别估算了该尿塔的化学爆炸能量、物理爆炸能量及后者的危害范围.结果发现前者小于尿塔的现场破坏能量,而后者的破坏范围则与现场的实际情况相符.结果表明该尿塔发生的是由尿塔应力腐蚀开裂而引起的物理爆炸过程.To determine the explosion cause of Pingyin urea reactor, the chemical and physical explosion energy of the reactor and the hazardous scope of the later were estimated based on the mass estimation of the reactor. It was found that the chemical energy is less than the destructive one of the local reactor, and the hazardous scope of the physical explosion fits with the pracrice. The results show that the explosion of the reactor is the physical one caused by the stress corrosion cracking of the reactor.
