density of occupancy的意思|示意

CT findings: the scan showed slightly higher density of occupancy with the shape of round or oval, without calcification or peripheral calcification.

CT检查所见：平扫一般表现为类圆形稍高密度占位，无钙化或边缘有钙化。

In accordance with three classical traffic flow parameter models based on density, three kinds of occupancy-speed models and occupancy-flow models are deduced in this paper.

根据三种经典的基于密度的交通流参数模型，分别推导了三种占有率速度模型和占有率流量模型。
