When the process was reversed ,the solution was sucked out of the droplet.A picture was captured before the droplet contact line receded.The contact angle in this case was marked as receding contact angle (RCA).The figure below shows how the contact angles were measured.
2.5 AFM imaging and force measurements of BE6,BE8 and BE12 on four substrates with extreme hydrophobicity and hydrophilicity
The aggregate structures of the three surfactants absorbed on fore substrates were studied by simultaneously measuring surface separation F(D) profiles,and imaging surface topography.All force curves were taken in Contact Mode unless specified.All surfactant concentrations were maintained at 2×CAC（or 2×CMC）.At this concentration,BE8 and BE12 formed clear solutions while BE6 formed slightly cloudy solution.
On mica
At 2×CAC,the AFM images were featureless on mica for all three trisiloxane surfactants.Figure 2.7 shows the F(D) profile of BE6 on mica.
A purely attractive force was observed at 5 nm and it increased in magnitude to -0.4 nm at contact.The F(D) curves measured in BE8 and BE12 solutions on mica were similar to Figure 2.7 with slight variations in the separation distance of the jump-in point.The jump-in point,as marked in Figure 2.7,is defined as the start of the unstable region (or gap) in force measurement when the cantilever tip snaps suddenly onto the substrate.This cantilever instability is caused by a force gradient that is lager than its spring constant.The force curves measured in the trisiloxane surfactant solutions were somewhat different form that measured in pure water.

当过程被逆转时,溶液被吸出液滴.在液滴接触线后退前拍一张照片.在这种情况下的接触角被标记为后退接触角（RCA）.下图示出了接触角的测量方法.
2.5 在具有极端疏水性和亲水性的四个基片上BE6,BE8和BE12的AFM（原子力显微镜）成像和力测量
在前面基片上吸收的三种表面活性剂的团聚结构 通过同时测量表面分离F（D）分布,和成像表面形貌进行了研究.除非另有规定,否则所有的力曲线都在“接触模式”下截取.所有表面活性剂的浓度均维持在2× CAC（或2 ×CMX）.在此浓度下,BE8和BE12形成清澈的溶液,而BE6形成略微浑浊的溶液.
在云母上
在2× CAC下,对全部三种三硅氧烷表面活性剂来说,原子力显微镜图像在云母上都是没有特色的.图2.7BE6 在云母上的F（D）分布.
在5nm处观察到了一个纯粹的吸引力,而在接触下它的幅度上升至-0.4nm. 在云母上的BE8和BE12溶液测得的F（D）曲线类似于图2.7,只是跳点（jump-in point）的分离距离有细微变化.跳点如图2.7中标志的那样,被定义为悬臂尖端突然打击在基板上时力的测量不稳定区域（或间隙）的开始.这一悬臂不稳定性是由一个比其弹簧常数大的力的梯度引起的.在三硅氧烷表面活性剂溶液中测得的力的曲线与在纯净水中测得的曲线有些不同.
再问： 师兄怎么这么专业啊，英语很好吧
再答： 我是在研究所搞翻译工作的，你这个内容我也不大熟悉，不过应该没有大的问题。
