The interface behavior between essence and ethylene - vinyl acetate copolymer pallets was studied so that necessary data were obtained to guide the preparation of fragrant masterbatch. the adsorption type and wettability between essence and the copolymer pallets were analysed by measurements of fourier transform infrared spectrum, surface tension, contact angle and specific surface area. the technical factors affecting absorptivity such as the charge ratio, temperature, pressure and stirring speed were studied by series of adsorption experiments. the results showed that the adsorption of essence on the surface of ethylene - vinyl acetate copolymer pallets is physical in nature. essence couldn ' t moisten the surface of ethylene - vinyl acetate copolymer pallets absolutely, but it could be soaked into the surface of the pallets partly. adsorptivity could be increased by enhancing the temperature, pressure and stirring speed, but the extension of adsorption time had little influence on adsorptivity

Fabrication of nanostructures based on spm as an extension to spm imaging, referred to as scanning probe nanofabrication ( spn ) is an emerging technique undertaken at labs in the past ten years that comprises manipulation of atom or molecule in a bottom - up paradigm and scanning probe lithography ( spl ) in a top - down paradigm. in chapter one, in the light of decentralized experimental data in this respect, the author, classify in an analytic approach the literature concerned as electrical spl, mechanical spl, thermal spl, and optical spl in terms of different mechanisms of interplay between a probe and a surface of a sample, after describing the most important of this type of microscopy, i. e., scanning tunneling microscopy and atomic force microscopy
由於這項技術的實驗數據比較分散，因此，作者在論文的第一章里首先介紹了掃描探針顯微鏡的兩個最重要的類型，即掃描隧道顯微鏡和掃描原子力顯微鏡的工作原理；然後根據加工方式的不同把它分為自下而上的掃描探針原子（分子）操縱與自上而下的掃描探針刻蝕兩大類；而根據掃描探針與樣品的不同作用機理，對掃描探針刻蝕加工又進行了歸納與綜述，對其特殊的加工方法作了原理性的介紹，並分析了目前存在的共性問題與應用前景。
