Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and beneficial effect, the now skill to the present invention
Art scheme carry out described further below, but it is not intended that to the present invention can practical range restriction.
Embodiment 1
Present embodiments provide a kind of fission track preparation of sections method (Fig. 1 is the flow chart of the method), it includes
Following steps：
The first step：Obtain the apatite particle 1000-2000 that diameter is between 60-200 μm using 150 aim cell sieve screenings
?；Classified according to crystal optics, the apatite in nature belongs to hexagonal prism body, Fig. 2 is to observe under scanning electron microscope
Apatite image, Fig. 3 be apatite particle largest face schematic diagram；
Second step：With 1:3 volume ratio allotment Epothin Epoxy Resin (epoxy resin) and Epothin
Hardener (coagulator), stirs 5 minutes, makes their mix homogeneously, dip in 2-3ml with tiny stirring rod and drop on microscope slide, so
It is slowly injected into the apatite particle of select afterwards, then is slowly stirred resin and apatite particle with toothpick, treat apatite particle
Sink to resin bottom and disperse spread, stand 2 days, treat that resin solidifies completely, (Fig. 4 is at the beginning of the thin slice of preparation to prepared thin slice first product
The schematic diagram of product)；
3rd step：Using double faced adhesive tape, microscope slide is fixed on Leica EM TXP and refines on the object stage of all-in-one, then
The diamond sand paper that granularity is 15 μm is fixed on mill；With pure water as lubricant, pressure parameter is set to 18N, mill
Disk rotating speed is roughly ground (state before grinding is shown in Fig. 4) under the grinding condition for 5000-6000rpm；In process of lapping, pass through
The binocular moment observes degree of grinding, probably grinds 15 minutes it can be seen that most of (60%-80%) apatite particle exposes
In outside；
4th step：The diamond sand paper that 15 μm on mill of diamond sand paper is replaced with 9 μm is refined, with pure water
For lubricant, pressure is 18N, and speed of grinding plate is 5000-6000rpm, passes through binocular vision grinding effect at intervals of two minutes, treats
Till being milled to most of granule (50%-70%) largest face；
5th step：9 μm on mill of diamond sand paper is replaced with 3 μm of diamond sand paper and carries out fine grinding, still with pure
Water is lubricant, but pressure parameter is set to 12N (in case pressure is excessive, crushing mineral grain), and speed of grinding plate is reduced to 3000-
3500rpm, continues to grind it is therefore an objective to remove the big scratch that corase grind produces；By binocular vision grinding effect, general 10 points
Zhong Hou, now the scratch on resin and mineral is little；
6th step：After grinding terminates, by 3 μm of diamond sand paper of mill be replaced with polishing cloth (Struers A/S company
MD-Chem polishing cloth), and with 1 μm of Al2O3Polishing fluid is lubricant, polishes general 20 minutes, and in removing fine grinding, residual is trickle
Scratch, prepared fission track thin slice.
Using fission track Autoscan auto testing instrument, above-mentioned track fission thin slice is amplified 1000 times to be observed, send out
Existing resin and apatite particle burnishing surface unusual light, nothing significantly scratch and pit.Thin slice, can be in phosphorus after chemical etching
Which limestone particles surface is easily identified out is fission track vestige, greatly reduces the system being come by production effect difference band
Meter error.Fig. 5 is that the track etching hole seen under fission track auto testing instrument reflected light after the thin slice making etches is (i.e. black
Point).
