In view of smaller and thinner samples required in grinding slice for microprobe analysis , three steps are used : establishing a thinner grinding plane on the center of homogenized crystalloid melt inclusion sample , grinding the surrounding parts of the sample to the thickness as the center , polishing the grinded sample slice in order to expose the melt inclusion to the sample surface 摘要針對磨制樣品十分細小和較薄等特點,采用如下三個步驟磨制:以加熱過的細小樣品為中心創建一磨制平面;將樣品周圍的巖石薄塊磨至接近細小樣品的相同厚度;在拋光機上拋光,使包裹體完全露出表現。

The topography and the nano - mechanical property of the sample before and after self - assembly was characterized by afm , and the factor attributed to the change was analyzed . based on the above conclusion , the nano - mechanical property of the sample fabricated with the technology based on the scratch of afm microprobe combining traditional self - assembly method was analyzed . it was proved that this method could carry out controllable self - assembly on silicon surface ; finally , the nano - mechanical property of the sample fabricated with the technology based on the cutting of diamond tool was measured , and this method was proved to be a quick and convenient mean that could carry out controllable self - assembly on silicon surface according to the nano - mechanical property of the samples fabricated by the two method before 之后利用原子力顯微鏡對組裝前后的樣品進行了表面形貌和納米機械性能的表征,分析了可能導致其變化的原因;借助所得的結論,對基于原子力顯微鏡微探針的刻劃與傳統自組裝方法相結合的自組裝加工技術所制備的樣品進行了納米機械性能的分析,證明這種方法能夠實現硅基底上的可控自組裝;最后,對基于金剛石刀具切削的自組裝加工技術所制備樣品的納米機械性能進行了檢測,通過和前兩種方法制備的自組裝結構的納米機械性能進行對照,證明這種方法可以方便快捷的實現硅基底上的可控自組裝,從而實現“割草種花”的構想。
