What is the meaning of "tens of microns to tens of millimeters in length"? I know this is talking a samll scale in length, but it is hard for me to understand "tens of millimeters" between "ten of millimeter". Please talk me the difference. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.117.95.221 ※ 編輯: james660 來自: 140.117.95.221 (04/02 06:15) ※ 編輯: james660 來自: 140.117.95.221 (04/02 06:16)
