| 中文摘要: |
| 运用微裂纹和热应力理论，根据建立的火灾中窗玻璃传热模型，从理论和实验上，系统地探讨了窗玻璃热破裂机理及其主要影响因素，并建立了一种预测窗玻璃热破裂时间的方法。对普通平板玻璃进行了大量热破裂试验，研究了其破裂规律和特征，提出了热破裂三种模式及其发生条件。 |
| 英文摘要: |
| In this article the mechanism of the thermal breaking of window glass and it’s main affacting factors have been studied and discussed by means of the theories of mini cracks and thermal stress,and the heat transfer model in compartment fires . A method of predicting the time to the breakage of window glass is also presented. The thermal breaking tests have been carried out and the mode of the breakage and it’s conditions are generalized. |
