Looks are unable to measure single pore volume.
The reverse-engineering of early stage mainly passes through contact type probe measurement and optical non-contact measurement 3D solid, both sides
Method can only measure exterior contour；Although existing nuclear magnetic resonance imaging and scanner scanning can measure the in-profile of object,
But the size that the above method can survey entity is very small, and precision is low, is not capable of measuring common metal material；With industrial in recent years
The development of CT technology is possibly realized the reconstruct of alloy in-profile.
Summary of the invention
The purpose of the present invention is to provide a kind of metal inside stomatal apparatus types to measure the method with three-dimensional appearance reconstruct,
The deficiency of conventional method is solved with it, specifically includes the following steps:

(2) virtual picture obtained is imported into medical image software according to the number order of picture obtained by step (1)
In MIMICS 20.0, the three-dimensional appearance of alloy is reconstructed.
(3) the volume V of sample solid portion is directly read after reconstruct three-dimensional appearance1, utilize formula ρ=V1/ V calculates hole
Rate, ρ indicate porosity.
(4) stomata is individually extracted one by one and is measured the volume of each stomata, save stomata shape appearance figure, count gas
Hole sum N calculates stomatal frequency p, V representing sample volume using formula p=N/V.
(5) the length L and volume V for measuring each stomata one by one, utilize formulaCalculate the flat of single stomata
Equal diameter R1。
(6) to the average diameter R of single stomata1It after summation, is averaged, obtains the average pore diameter of sample.
Preferably, every 10 microns of run-downs when step (1) interrupting layer of the present invention scans.
Beneficial effects of the present invention: the present invention, both can be to the shape of metal inside stomata in the case where not destroying sample
Looks parameter measures, and can carry out Reverse reconstruction to stomata.
