【請(qǐng)教】AFM圖片中roughness分析

http://pic.www.gaoyang168.com/201011/11/576263_174906.jpg 1 . Peak The Peak feature, when switched on, isolates specified height portions of the image (peaks) from background data.我的理解是當(dāng)peak=on,peak threshold value=8 nm的時(shí)候,數(shù)據(jù)中與peak相差8 nm的數(shù)據(jù)都會(huì)被過(guò)濾掉? 2. Mean The average of all the Z values within the enclosed area. The mean can have a negative value because the Z values are measured relative to the Z value when the microscope is engaged. This value is not corrected for tilt in the plane of the data; Therefore, plane fitting or flattening the data changes this value. Image Mean Mean value of data contained within the image. Mean按照我的理解是選定區(qū)域平均值的意思,Image Mean按照我的理解是整個(gè)圖片的平均值,但是從圖像結(jié)果明顯不是。。。請(qǐng)問(wèn)Mean和Image Mean分別代表什么? 此圖Image Mean= -0.0907ang, Mean=-0.0404 nm,請(qǐng)問(wèn)ang是什么意思? 3 Image Projected su**ce area: Area of the image rectangle (X*Y) 我的理解是圖像面積 5*5=25micrometer 2 Image su**ce area: The three dimensional area of the entire image. This value is the sum of the area of all of the **s formed by three adjacent data points. 我的理解是三維面積,就是相鄰三點(diǎn)所組成的面積,但是數(shù)據(jù)上顯示也為25 micrometer2.如果正如我所想的相鄰三點(diǎn)的表面積肯定比這大…請(qǐng)問(wèn)Image su**ce area代表什么? Image su**ce area difference: different between the image’s three dimensional su**ce area and two dimensional projected su**ce area. 我理解為三維面積與圖像面積的差然后除以三維面積,這樣算的話結(jié)果為0.但是數(shù)據(jù)顯示0.144%。。。請(qǐng)問(wèn)這個(gè)Image su**ce area difference參量代表什么? 多謝! |
