3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Microscopic image analysis micro-imageanalysis
The microscope imaging fiber amplification observed morphology, structure, and measurement statistics.
3.2
Number average fiber length meanlength
The results of the measured fiber length divided by the number of total income, by L.
3.3
Length - weight average fiber length length-weightedmeanlength
By the length of the calculated weight-average fiber length represented by L1.
3.4
Quality - Weight average fiber length mass-weightedmeanlength
Calculated by the mass of the weight average fiber length, indicated by LW.
Note. Quality - Weight average fiber length of previously known weight - weight average fiber length.
Principle 4
The fiber dyed with a microscope at a magnification using a digital camera will be amplified fiber image signal into a digital electronic signal transmission
To the computer, the computer processing is displayed on the computer screen. Click with the mouse on the screen at both ends of single fiber (or with the mouse
Display along the fiber direction of the fiber segment is subdivided into multiple linear) measurements, the computer automatically track the measured fiber, fiber skeleton structure depicted,
