ambient medium

According to corresponding evaluation model, the paper estimates the exposure dose of PTS through three exposure ways in different ambient medium.

根据相应的评价模型，对多介质环境中PTS的暴露量进行了估算。

In 1952, Bondi solved the hydrodynamic version of the star in a static ambient medium, who showed a certain gravitational capture radius, got Bondi accretion rates.

环境介质对大跨斜拉桥动力特性的影响

It has been proved both by the test and by the theoretical analysis that the self-cooled induction motor of the enclosed type dif-fuses its heat in such a passage: the winding → the stator core → the frame → the ambient medium.

实验测试与理论分析都证明：自扇冷式封闭型感应电动机的散热路径为绕组→定子铁心→机座→周围介质。

Using the health risk assessment model of chemical carcinogens and non-carcinogens and combing with the maximum acceptable risk level recommended by relative agencies and authors, the paper develops the risk assessment of carcinogenic and non-carcinogenic PTS in different ambient medium of Shanghai.
