Cov kua nitrogen muaj kev siv dav hauv kev lag luam, tshuaj, thiab kev tshawb fawb tshawb fawb. Raws li cov kua cryogenic, kua nitrogen muaj ntau yam tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, ua rau nws ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Nov yog qee qhov kev siv tseem ceeb ntawm cov kua nitrogen:
1. Cryopreservation: Cov kua nitrogen muaj qhov kub tsis tshua muaj siab, ncav cuag -196 degrees Celsius, ua rau nws feem ntau siv rau cryopreservation ntawm cov qauv tshuaj lom neeg, tshuaj, thiab khoom noj khoom haus. Qhov ntsuas kub qis no tuaj yeem ua rau qeeb lossis nres qhov kev loj hlob ntawm cov kab mob thiab cov tshuaj lom neeg, yog li ncua lub txee lub neej ntawm cov khoom.
2. Kev lag luam khoom noj khoom haus: Hauv kev ua zaub mov, cov kua nitrogen tuaj yeem siv los ua kom khov cov khoom noj sai sai, txo cov tub yees kev puas tsuaj thaum tuav cov khoom tshiab.
3. Industrial Manufacturing: Kua nitrogen yog siv nyob rau hauv industrial ntau lawm rau tu, txias, thiab raws li ib tug inert roj los tiv thaiv ib puag ncig. Piv txwv li, hauv kev ua hlau, cov kua nitrogen tuaj yeem siv los ntxuav cov siab - cov khoom ua tau zoo, tshem cov roj thiab oxides.
4. Kev Kho Mob Field: Hauv cov tshuaj, kua nitrogen feem ntau yog siv rau kev kho mob cryotherapy, xws li cryopreservation kom tshem tawm cov kab mob ntawm daim tawv nqaij xws li warts thiab moles, thiab rau kev kho mob ntawm qee yam qog noj ntshav.
5. Kev Tshawb Fawb Txog Kev Tshawb Fawb: Hauv kev tshawb fawb tshawb fawb, kua nitrogen yog qhov tseem ceeb rau kev tshawb nrhiav cryogenic, siv hauv kev sim hauv cryogenic physics, chemistry, thiab biology.
6. Aerospace: Cov kua nitrogen yog ib feem ntawm lub foob pob hluav taws, siv los muab cov pa oxygen xav tau rau kev sib txuas.
7. Kev Lom Zem thiab Kev Ua Yeeb Yam: Cov kua nitrogen kuj yog siv rau hauv kev lom zem thiab kev tsim txuj ci, xws li cov duab puab cov dej khov thiab kev ua yeeb yam cryogenic.
Cov ntaub ntawv ntxiv:
1. Cov kua nitrogen feem ntau yog npaj los ntawm cov cua txias nitrogen hauv huab cua kom tsis tshua muaj kub, ces liquefying nws los ntawm compression thiab txias.
2. Cov kua nitrogen sai sai vaporizes ntawm lub siab ib txwm, absorbing ib tug loj npaum li cas ntawm tshav kub, thiab yog li ntawd feem ntau yog siv rau txias thiab tub yees.
3. Kev cia thiab kev thauj mus los ntawm cov kua nitrogen yuav tsum tau ntim tshwj xeeb vim nws cov evaporation ceev heev, thiab vim gaseous nitrogen yog compressible heev.
