今年145号《火灾》杂志发表了日本于5月24日至25日举行的1983年度研究报告会概要。报告会的研究课题共四十九项。现摘择其中四项,供参考。 1.气体爆炸引起火灾的研究: 为了弄清气体爆炸时热向可燃物传导的情况,研究人员在模拟试验室的窗上糊了腊纸,以替代玻璃,并在室内放了腊纸作为可燃物。然后,用电火花点燃不同当量比的甲烷——空气混合气,使腊纸起火,测定室内压力变化和观察腊纸起火状况。结果发现,
This year’s 145th issue of Fire magazine published a summary of the 1983 annual study held in Japan from May 24th to 25th. A total of 49 research topics will be reported at the conference. Now select four of them for reference. 1. Study of Gas Explosion-Induced Fires: To understand the heat conduction to combustibles during a gas explosion, researchers plastered wax paper on the window of a simulated laboratory to replace glass and put wax paper in the room as a flammable Things. Then, electric sparks were used to ignite the methane-air mixture of different equivalence ratios to ignite the wax paper, measure the change of the indoor pressure and observe the fire condition of the wax paper. turn out,
