Txoj kev pom cov iav hlaws yog ib yam ntawm cov iav zoo uas tsim los ntawm cov iav rov ua dua tshiab raws li cov khoom siv raw, crushed thiab melted ntawm kub kub los ntawm natural gas, uas yog pom raws li ib tug tsis muaj xim thiab pob tshab sphere nyob rau hauv lub microscope.Nws qhov refractive index yog nruab nrab ntawm 1.50 thiab 1.64, thiab nws txoj kab uas hla yog feem ntau ntawm 100 microns thiab 1000 microns.Cov hlaws iav muaj cov yam ntxwv ntawm cov duab kheej kheej, cov khoom zoo, qhov sib xws, pob tshab thiab hnav tsis kam.
Txoj kev pom cov iav hlaws raws li txoj kev kos duab (xim xim) hauv cov khoom siv reflective, tuaj yeem txhim kho txoj kev kos duab xim retro-reflective kev ua tau zoo, txhim kho kev nyab xeeb ntawm kev tsav tsheb hmo ntuj, tau raug txheeb xyuas rau cov chaw thauj mus los hauv tebchaws.Thaum lub tsheb tsav tsheb thaum hmo ntuj, lub teeb taub hau ci rau ntawm txoj kev kos kab nrog cov iav hlaws, kom lub teeb ntawm lub taub hau tuaj yeem cuam tshuam rov qab mus rau qhov sib npaug, yog li ua rau tus neeg tsav tsheb pom kev nce qib thiab txhim kho kev nyab xeeb ntawm hmo ntuj. tsav tsheb.Niaj hnub no, cov iav tsom iav tau dhau los ua cov khoom siv tsis pom kev hauv kev nyab xeeb khoom.
Cov tsos mob: huv, tsis muaj xim thiab pob tshab, ci thiab puag ncig, tsis muaj npuas los yog impurities.
