- 摘要:
- 着重于从事同一堆积材料试体在不同温度下受振荡之上升速度的变化试验，采用粒径 3.9m m之百丽珠做为堆积材，底层堆积高度（Hd 分别为 4，8，12，18cm共 4种高度，于放置同粒径不同颜色之百丽珠做为追迹珠后，上层堆积厚度（Hu）为 2 cm，试体初始温度 t设定为 20，21，22，23，24，25，26，27，28，29，30，31℃等 12种温度一共 48种处理。每一处理 5重复试验得一追迹珠上升 2 cm所需时间（T）与试体温度（t）之关系式。
- Abstract:
- The author mainly engaged in an experiment with a piles of materials to test the changes of the shocked blanket’s ascend velocities under various temperatures.Using 3.9mm particle diameter of Bailizhu as piled material,the piled ground height(Hd) is 4,8,12 and 18cm respectively.After taking the various colour’s particles as the trace lines,the overlying piled thickness (Hu) is about 2 cm.The temperature treatments are 20,21,22,23,24,25,26, 27,28,29,30 and 31℃ (t),under 5times replications,the relation between the particles and times(T) needed by particles risen 2 cm were established here.
