不(bu)同(tong)植(zhi)物(wu)都(dou)有(you)不(bu)同(tong)大(da)小(xiao)的(de)葉(ye)片(pian)，如(ru)果(guo)現(xian)在(zai)有(you)一(yi)項(xiang)研(yan)究(jiu)工(gong)作(zuo)需(xu)要(yao)測(ce)量(liang)葉(ye)片(pian)的(de)麵(mian)積(ji)，我(wo)們(men)又(you)應(ying)該(gai)如(ru)何(he)去(qu)做(zuo)呢(ne)？過(guo)去(qu)，人(ren)們(men)通(tong)常(chang)會(hui)先(xian)借(jie)助(zhu)皮(pi)尺(chi)量(liang)出(chu)葉(ye)片(pian)的(de)長(chang)和(he)寬(kuan)

，操作也非常簡便，將葉片（無需采摘）置於測量掃描區，按下指模，幾秒鍾就能得出結果。
