触角

Three main factors (viz. surface potential, particle size and surface wettability) that influence the interparticle interaction between titanaugite and ilmenite particles were investigated in detail through the calculation of DLVO theory, measurements of electrokinetic potential and contact angle, experiments of floatation and characterization of scanning electron microscope.

通过DLVO理论计算、动电位、接触角和扫描电镜检测及浮选试验，研究影响钛辉石和钛铁矿颗粒间相互作用的3个主要因素，即表面电性、颗粒粒径和表面润湿性。

A series of modified polyurethane elastomer materials with different amino siloxane content were synthesized,which were based on polyoxypropylene glycol,aminoethyl aminopropyl poly,toluene diisocyanate and the curing agent dimethylsulfide toluylenediamine.

以聚氧化丙烯二醇或聚氧化丙烯三醇、氨乙基氨丙基聚二甲基硅氧烷、甲苯二异氰酸酯为原料在无溶剂条件下制备预聚体，利用二甲基硫甲苯二胺为固化剂合成一系列氨基硅油改性聚氨酯弹性体材料，并对材料的力学性能、耐热性、表面水接触角等性能进行了测试。

The research indicated that, the structure inside the pure C8TES SAM was indeed loose and unassembled completely, the molecule density inside the SAM was very low, which would result in an ultra-low surface contact angle, only 20～21°, on the C8TES SAM surface.

我们的研究表明，由于C8TES分子头部三个乙氧基形成的空间(来源：b5e5ABe3C论文网www.abclunwen.com)位阻的影响，C8TESSAM的内部处于一种不完全组装的松散状态，所形成的自组装单分子膜内分子密度偏低，造成C8TES SAM的表面接触角偏低，只有20～21°。

And the superhydrophobic phenomena could be explained by two typical thoeries: Wenzel model and Cassie model.

在表征表面超疏水性时，除常用的θ、α外，接触角滞后Δθ、斜面上液滴滞留在材料表面上的最大半径Rc、两种状态转化时的临界压力Δp以及液滴落下后能反弹的临界撞击速度Vc也是非常重要的参数。

The physico-mathematical model was established by considering the variation of the apparent contact angle to describe the configuration of the total extended thin film region,including the equilibrium region,the interline region and the meniscus region.In addition,the ratio of disjoining pressure and capillary pressure was introduced to distinguish the film ranges of the different regions by considering the influence of film configuration,liquid property and channel size.

借助表观接触角的演化，建立起包含固有弯月面、过渡薄液膜和平衡区三部分的延展薄液膜形状及其表面蒸发的物理数学模型，并考虑液膜的结构、工质物性和通道特征尺度，引入分离压力和毛细压力比确定液膜不同区域的范围。

The fishes which dwell therein are quaint and strange; their huge heads, prodigious jaws, and long tails and tentacles are, as it were, gross exaggerations of the common and conventional forms. We look in vain for any purposeful cause or physiological explanation of these enormities; and are left under a vague impression that life has been going on in the security of all but perfect equilibrium, and that the resulting forms, liberated from many ordinary constraints, have grown with unusual freedom.

生活在深海的鱼类长得很奇特有趣，它们有巨大的头，很大的嘴巴、很长的尾巴与触角，长得就是一副标准的夸张模样，我们无法给予这些奇特夸张任何果断的原因或生理上的解释，只能对於这些生命在几近完美平衡的安全中持续，以及从一般限制中解放并独特自由生长的形体，徒留一丝模糊的印象。

The contact angle of glassfiber epoxy resin fluoridized by 3-(1H, 1H, 5H-Octafluoropentyloxy)-1, 2-Propenoxide hasincreased from 51.3°to 75.3°, and the surface tension has reduced from 36.5mN/m to25.5mN/m accordingly.

同时经过环氧丙基八氟戊醚处理的环氧玻璃钢表面对水的接触角也由原来的51.3°增大到75.3°，其表面张力由36.5mN／m减小到25.5mN／m，达到一定的疏水疏油效果。
