Abstract : molecular deposition ( md ) film, a nano film, is assembled by the interaction of static charge between cationic and anionic compounds. the micro - friction properties of an md film on silica has been studied with atomic force microscope ( afm ). it has been found that the md film has lower coefficient of friction as compared with the original surface of silica. moreover, based on the analyses of the surface force versus distance curves, photographic image, friction force image, and modulated force image, it is concluded that the friction reduction effect of md film on silica is attributed to the surface adhesion reduction and surface micro - modification
文摘:利用原子力顯微鏡對石英巖表面單層分子沉積膜的微觀摩擦特性進行了研究，發現該分子沉積膜具有一定的減摩性.通過對其表面力-位移曲線、表面形貌像、調制力像和摩擦力像的進一步分析表明，石英巖表面分子沉積膜具有減摩作用的原因在於它能夠降低表面的粘著力並對表面具有微觀修飾作用 -

When the width of the foundation is smaller, the friction force is firstly increased from zero at the central area of the foundation, then decreased to zero at the edges of the foundation, hence there is a peak ; when the width of the foundation and the thickness of the soft ground is larger, the frication force is almost zero from the central area of the foundation to a certain distance, then increased, at last decreased to zero at the edges of the foundation, therefore there is a peak ; and when the width of the foundation is larger and the thickness of the soft ground is smaller, the friction force is firstly increased from zero at the central area of the foundation in the negative direction, then decreased to zero, so there is a negative peak, then increases in the positive direction, eventually decreased to zero at the edges of the foundation, hence there is a positive peak
當基礎寬度較小時，從中心線為零處開始增加，達到峰值后，開始減小，直至基底邊緣處為零；當基礎寬度和軟土地基厚度較大時，從中心線處開始，向外側延伸一定距離，幾乎為零，然後開始增加，達到峰值后，開始減小，直至基底邊緣處為零；當基礎寬度較大，並且軟土地基厚度較小時，從中心線為零處開始反向增加，達到反向峰值后，然後反向減小，減小到零后，逐漸正向增加，達到峰值后，再逐漸減小，直至基底邊緣處為零。 -
In this thesis, the law of reduction friction and the law of prolong the transportation distance are discussed and the formula of prolong transportation distance rate has also been obtained
而且，本文探討了加氣減阻和延長排距的機理，提出了加氣延長排距百分數公式。 -
Moreover, it was found that the microstructure and physical properties of dlc film were affected to some extent by the distance between target and substrate. when the distance between target and substrate increases, sp 3c content in the deposited dlc film decreases. accordingly, the value of surface roughness, microhardness, friction coefficient, residual stress and band gap became lower in the same way
此外，靶基距對dlc薄膜的結構和性能也有一定的影響，隨著靶基距增加， dlc薄膜中的sp ~ 3c含量減少， dlc薄膜的表面粗糙度降低，顯微硬度降低，摩擦系數減小，殘余應力減小，光學帶隙eg減小。 -
