一次黄海海雾的三维数值模拟研究 总被引：2，自引：0，他引：2
本文利用1个考虑了地形效应，植被影响，长波辐射，地表能量收支，液态水的重力沉降等影响雾的形成和发展主要因子的三维海雾模式，模拟了1995-06-01发生在黄海的1次实际海雾过程，分析了海雾生长、发展和消亡过程中液态水含量和其它物理量的三维时空分布变化特征，结果表明，该模式较能好地模拟出黄海海域实际的海雾生消过程，对海雾的三维结构有一定的模拟能力。 相似文献

遥感大气中汽态水和液态水含量的实验研究 总被引：1，自引：1，他引：1
根据微波在大气中的辐射传输理论，采用接收１．３５ｃｍ和８ｍｍ波段的大气噪音，推算大气中水汽和液态水含量，研制了双通道微波辐射计，进行遥感实验，文章中对微波辐射计测得的数据如何校正，展开了详细的讨论，这将在监测和利用空中水资源的科学实验中发挥作用。 相似文献

We investigated the influences of liquid water transfer property of cotton fabric on human physiological responses, such as ear canal temperature, heart rate, blood pressure, stress hormone, during exercise and recovery. Long sleeves cotton knitted sportswear treated to have special liquid water transfer property were prepared; （1） Hydrophilic; （ 2 ） Hydrophobic; and （ 3 ） Moisture Management （MM）. Wearing these garments, human subjects ran on treadmill according ＂to a pre-designed experimental protocol. It was found that during exercise hydrophilic cotton caused significantly higher mean skin temperature than MM and hydrophobic cotton fabrics, while during recovery, hydrophilic and MM cotton fabrics caused significantly higher mean skin temperature than hydrophobic cotton fabric. Hydrophilic cotton fabric caused significantly lower heart rate than MM cotton fabric, lower systolic blood pressure than MM and hydrophobic cotton fabrics. Hydrophobic cotton fabric caused significantly higher urinary catecholamine volume than hydrophilic and MM cotton fabric, indicating stronger physical stress. Hydrophilic cotton fabric caused significantly stronger thermal and humidity sensations than MM and hydrophobic cotton fabrics at the end of first and second exercise sessions. Hydrophilic cotton fabric caused significantly stronger discomfort sensation than hydrophobic cotton fabric at the end of first session of exercise. In the end of wear trial, MM cotton fabric caused significantly higher tiredness sensation than hydrophilic and hydrophobic cotton fabrics. 相似文献
