制药粉末休止角测定仪操作流程
.定义Definition :休止角是指粉体堆积层的自由斜面在静止的平衡状态下，与水平面所形成的角the angle of repose is the maximum angle formed between the free slope of the powder accumulation under static equilibrium state and horizontal plane.

.工作原理principle:休止角常用的方法是固定圆谁法(亦称残留圆锥法)。固定圆锥法将粉体注入到某***有限直径的圆盘中心上，直到粉体堆积层斜边的物料沿圆盘边缘自动流出为止，停止注入，测定休止角。
the usual method of anale of repose is to fix the cone method (also caled residual conic method).Fixed cone method : inject powder tothe center of disc with limited diameter, until the hypotenuse powder accumulation of material automatically flow along the edge of
disk, stop injection, measure angle of repose.
