1·The result shows that viscidity dissipation and tower effect are main reasons of wake eddy distortion.
结果表明：粘性耗散与塔架效应是引起尾涡变形的主要原因。
2·We also consider the effect of vortex decay over time caused by the viscidity of atmosphere in our vortex model in estimating the vortex effect experienced during the close proximity formation flight.
在估算紧密编队飞行中长机翼尖涡对僚机的影响时，本文在所用到涡模型中也考虑了由空气粘性引起的涡流随时间的衰减效应。
3·According to real liquid movement equation we can know that liquid will produce energy losses when flowing because of viscidity, which make systematic efficiency reduce.
根据实际液体伯努利方程可知，液体流动时，由于存在粘性，会产生能量损失，使系统效率降低。
4·The peculiar solution structure makes that solution have high-effect merit such as increasing viscidity, temperature resistance, salts tolerance, shear resistance, he overall propulsion nature.
这种特殊溶液结构使该溶液具有高效增粘性、抗温耐盐性、剪切恢复性以及整体推进等特点。
