The static permeability and resonance frequency decrease with the drop of temperature.
共振频率和准静态磁导率随温度降低而减少;
With wall paint and wood, for example, the drop of temperature will cause a sharp contraction in lacquer and wood interface, resulting in a variety of cracking phenomenon.
以墙漆和木器为例,气温急降会造成漆面和木器接口急剧收缩,引致各种开裂现象。
Results Before sudden drop of temperature, the levels of adrenal axis hormones and thyroid axis hormones were lower in the model group than those in the normal group(P<0.05 or P<0.01).
结果降温前,模型组大鼠肾上腺皮质轴激素水平和甲状腺轴激素的水平均低于相应的生理组大鼠(P<0.05或P<0.01)。
