It is found that contact angle decrease with power increase , and increase with pressure increase . the affect of treating time is very complex 时间对接触角的影响较为复杂，在30分钟内，接触角随溅射时间的增加而增大， 30分钟以后，接触角基本不变。
Compared with uncoated graphite , contact angle with water of all of the composite particles are much smaller and decreased gradually with the increase of the coating amount 包覆后，各类复合粉体与水的接触角都比未处理石墨低，而且随着包覆率增大，接触角有进一步降低的趋势。
Water contact angle measurement of the control and the modified plla membranes indicated that the hydrophilicity of the membrane was improved obviously after the grafting modification Atr - ir和xps测试结果证明了接枝聚合的发生。接触角测试结果表明改性后plla膜表面的亲水性明显提高。
Because of the larger contact angle 9 of low - energy surface , the phase transformation energy barrier of vapor is higher than those of high - energy surface , and the frosting of air cooler is effectively restrained ; 3 低能表面因水接触角大，水蒸气相变时的核化能障较大，从而有效地抑制了蒸发器的结霜。
And then make out the nonlinear equations from the mathematics models , the results includes : the contact angler , contact distortion and axial distortion of each rolling element in the bearing 求解两种数学模型的非线性方程组,计算出轴承各滚动体在不同工况下内、外圈接触角,接触变形和轴承轴向、径向位移等。
The influence of the slant on maximum stress in contact area is studied and the axial movement formula is modified . the idea of contact angle is presented to study the direct influence on the axial movement . 2 研究了这种倾斜对接触区最大压应力的影响，对回转窑轴向下滑计算公式进行了修正；提出了接触角的概念，分析了这种倾斜对窑体轴向运动速度的直接影响。
The contact angle with water is 64 ? for the thin film without annealing . after 650 ? annealing treatment , the contact angle becomes 0 . with proper sno2 doping , the hydrophilicity of tio2thin film will be also improved ( 3 )没有经过热处理的tio _ 2薄膜与表面水滴的接触角为64 ，经过650热处理后薄膜与水滴的接触角为0 ，掺杂sno _ 2对tio _ 2薄膜的亲水性有所改善。
The results of attenuated total reflectance - fourier transform infrared ( atr - ftir ) , x - ray photoelectron spectroscopy ( xps ) and contact angle measurement showed that the amphiphilic copolymer could self - segregate on the hydrophobic pdl - la surface 利用衰减全反射傅立叶转换红外光谱( atr - ftir ) 、 x -射线光电子能谱( xps )分析以及接触角测定对改性聚乳酸材料表面进行了表征。
The optical properties were characterized by uv - vis transmission spectrum . the hydrophilicity of the films was measured by a contact angle meter . and the mechanism of the film formation during the spray pyrolysis procedure was also discussed 通过xrd ， sem ， afm以及uv - vis光谱分析等一系列手段对薄膜的结构和性能进行了全面的研究，并且测量了不同薄膜在接收光照后接触角的变化。
The ratio f / c decreases with the increase of power , but increases when pressure increase . the power has more marked effect on f / c than that of pressure . contact angle of fluorocarbon films obtained at different of power , pressure and treating time 最后研究了不同功率、压力、溅射时间对氟碳膜憎水性能的影响，并测量了氟碳膜的接触角，发现接触角随功率的增加而减小，随压力的增加而增大。
