Qhov sib txawv tseem ceeb ntawm khov pob txha thiab khov khov yog qhov khov khov yog qhov tawg ntawm cov qauv khov kom nthuav tawm cov qauv sab hauv, thaum khov etching yog lub tshuab nqus tsev qhuav ntawm cov qauv tsis ruaj khov, khov thiab khov-kho cov qauv.
Kev khov pob txha thiab khov etching yog ob txoj hauv kev uas yuav pab tau los kawm cov ntsiab lus ntawm peb-seem qauv ntawm cov qauv lom. Froze fracturing yog ib txwm ua raws li khov etching. Kev khov khov cuam tshuam cuam tshuam nrog kev rhuav tshem cov qauv khov nab kuab, thaum khov etching yuav ua rau platinum-carbon replica ntawm lub ntsej muag tawg los ntawm cov hlwb khov.
Nkauj Fracture yog dab tsi?
Txias pob txha yog ib qho txheej txheem ntawm kev tawg ntawm cov qauv khov nab kuab. Cov txheej txheem no yuav pab kom nkag siab txog cov qauv ntawm cov qauv ntawm tes sib txawv nrog cov ncauj lus kom ntxaws txog lawv txoj haujlwm. Nyob rau hauv khov fracturing, cov qauv khov yog tawg siv lub microtome. Lub microtome yog ib qho cuab yeej zoo li riam uas txiav cov nqaij nyias nyias. Kev khov ntawm cov qauv yog ua tiav siv cov kua nitrogen.
Daim duab 01: Khov Fracture Device
Txias tawg tawg ua rau ob txheej txheej, pom cov ntsiab lus sab hauv ntawm daim nyias nyias. Thaum tus qauv raug puas lawm, nws yuav tsum tau siv khov etching txhawm rau khaws cov khoom tawg.
Nyob khov Etching yog dab tsi?
Freeze etching yog ib qho txheej txheem ntawm lub tshuab nqus tsev kom qhuav cov khoom siv roj ntsha khov khov. Nws koom nrog ua cov platinum-carbon replica ntawm lub ntsej muag tawg los ntawm cov hlwb khov. Feem ntau, khov etching yog ua tiav tom qab khov fracturing cov qauv lom. Thaum lub replica yog tsim, nws yog kuaj nyob rau hauv electron microscopy. Cov txheej txheem khov etching zoo ib yam li cov txheej txheem khov-qhuav ntawm cov txiv hmab txiv ntoo thiab zaub muag hauv khw muag khoom noj. Kev kho thiab lub cev qhuav dej tsis koom nrog kev khov kho.
Daim duab 02: Khov Etching
Lub tshuab nqus tsev tiv thaiv kev sib kis ntawm tus qauv. Tsis tas li ntawd, cov dej khov ntawm qhov chaw evaporates tam sim ntawd, nthuav tawm cov pob txha tawg. Ces ib tug nyias hlau duab ntxoov ntxoo yog tsim rau saum npoo. Cov yeeb yaj kiab hlau ntawm qhov chaw khov kho tawg yog ntxiv nrog cov pa roj carbon txheej. Ua li no, cov ntsiab lus ntawm qhov tawg tawg tau nthuav tawm.
Dab tsi yog qhov zoo sib xws ntawm Nroj Tsuag tawg thiab khov kho?
- Nkag tawg yog ua raws li khov kho.
- Lawv tau ua tiav rau cov qauv tshuaj lom neeg.
- Ntxiv mus, tus qauv yuav tsum tau khov ua ntej tawg thiab etching.
- Lawv yog electron microscopy qauv txheej txheem npaj.
Dab tsi yog qhov txawv ntawm Kev Kho Mob Khov thiab Khov Khov?
Txias pob txha yog cov txheej txheem rau kev sib cais ntawm cov qauv khov nab kuab. Freeze etching yog ua los ntawm platinum-carbon replica ntawm lub ntsej muag tawg los ntawm cov hlwb khov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm khov pob txha thiab khov etching.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm khov pob txha thiab khov etching hauv daim ntawv.
Summary – Nroj Tsuag Vs Nroj Tsuag Etching
Nyob hauv khov pob txha, cov qauv khov nab kuab yog tawg lossis tawg. Nyob rau hauv khov etching, sublimation ntawm nto dej khov nyob rau hauv lub nqus tsev vacuum yog ua tiav, thiab ib tug platinum-carbon replica ntawm lub fractured nto yog ua. Yog li, qhov no yog qhov sib txawv ntawm khov pob txha thiab khov etching. Ob txoj kev ua tiav thaum lub sij hawm ua qauv npaj rau electron microscopy. Cov txheej txheem no pab kom nkag siab txog cov qauv sab hauv thiab cov qauv peb sab ntawm cov qauv lom neeg.
