Abstract : the hot wire anemometer and the ensemble average method are used to measure and study the dispersion turbulent transient feature in a closed cylindrical explosion bomb . the comparison of the dispersion turbulent parameters from different shapes of closed explosion bombs is presented . the relation between errors and numbers in dispersion turbulent measurement with the ensemble average metod is discussed 文摘:采用热线风速仪和系综平均法测定和研究了封闭圆柱形粉尘爆炸罐内扬尘湍流的瞬态特性，并与球形爆炸容器内已测定的扬尘湍流瞬态特性进行了比较，对系综平均法用于扬尘湍流的测量误差与测量次数的关系进行了探讨。
