Experiments in surfactant solution penetration into the immersed fabric showed that the advancing contact angle is decisive one among several factors, such as contact angle, surface tension, etc. which can influence penetrating velocity. 通过表面活性剂溶液对被浸织物的渗透实验发现,在溶液的表面张力、静态接触角、前进接触角等因素中只有液体在毛细管内的前进接触角才是影响渗透速度的决定因素。
In the formation of generation characteristic by the frequent pulsations of condensing droplets, the greater possibility is that the droplets transform from the stage with an advancing contact angle to the state with an equilibrium contact angle while the liquid volume keeps unchanged. 在液滴频繁脉动形成分代分布特征的过程中,液滴由接触角为前进角状态脉动到等体积下接触角为平衡角状态的可能性较大。
Reason for which the advancing contact angle is a decisive factor is discussed in respect of both the principle of surface phenomenon and the relationship between advancing contact angle and penetrating time. 本文还从表面现象原理和数学分析两个方面讨论了为什么仅由前进接触角就能决定渗透速度的大小。通过归纳实验数据还发现,前进接触角与渗透时间的关系可用一个指数函数表示。
According to the theoretical derivation and Wilhelmy experiment data, the driving force of a droplet on the state of advancing contact angle ( ACA) and receding contact angle ( RCA) were analyzed. 根据理论推导和Wilhelmy法所测得的实验数据,分析得到了液滴在前进角和后退角状态时所受到的推动力。
The 1D hydrodynamics equation with the constant corner pressure model is used to calculate the advancing contact angle. 用一维流体力学方程,结合常拐角压力假设,计算了到达通孔出口的动态接触角。
