ESPITE the strong association between gastroesophageal reflux disease （GERD） and asthma has been undisputedly established and widely recognized by experts in advanced countries. Yet few topics in medicine are as controversial as the causal relationship between GERD and asthma： some argue that GERD causes asthma, while others think the other way around is true, still quite a few believe that bronchodilator medications are to blame. This controversy continues to be a conundrum or more piece of the puzzle.1 We would like to share two thoughts which might be a belated revelation with scholars and experts and invite them for further cooperative studies： the GERD-derived respiratory distress is not asthma, but GERD pure and simple; and the pathogenesis of respiratory distress is not asthma, but laryngotracheal irritation/spasm/suffocation.

发射膛炸的概率是评估武器使用安全性的重要性能指标。旨在研究某平衡抛射的单兵反装甲武器发射装药的发射安全性评估方法。分析了该武器系统的低温内弹道性能,建立了一种预测膛炸事故概率的方法,通过统计推断其低温最大膛压服从三参数Weibull分布,计算了其发射装药引起膛炸事故的概率。结果表明该武器发生膛炸概率较大,并通过改进消除了膛炸隐患。建立的膛炸概率预测方法可用于平衡抛射单兵反装甲武器、迫击炮、无坐力炮等武器的发射安全性分析。
