Hordhac Faahfaahinta Isbarbardhigga Wax-soo-saarka Walaxda Cabbirrada Dulqaadashada Dhumucda Darbiga Dushiisa Dhexroorka Dushiisa Dhamaystiraya Alxanka Kuul Daawaynta Kuleylka Tijaabada Aan Burbursanayn.
Maqaalkani wuxuu bixiyaa kood kale oo loogu talagalay adeegyada cuntada Australia.Tilmaamahan waxaa ka mid ah:
ASTM A269 "Qeexidda Ujeeddada Guud ee aan Xumaan iyo Welded Austenitic Tubiyaha Aan Lahayn"
ASTM A249 "Qeexitaanka Kuleyliyaha Austenitic, Kuleyliyaha Sare, Kuleyliyaha, iyo Tubooyinka Condenser Alxanka"
AS1528 waxa dib u eegis ku sameeyay 2001 dii daneeyayaasha muhiimka ah ee warshadaha cuntada iyo tuubooyinka Australia.AS 1528 waa mid gaar ah maadaama ay daboosho dhammaan qalabyada ku habboon marka laga reebo tubooyinka.
Dhammaan tilmaamuhu waxay tixraacaan darajooyinka birta ee caadiga ah sida 304, 304L, 316 iyo 316L.AS1528.1 waxay quseysaa dhammaan duplex iyo austenitic darajooyinka birta aan birta lahayn ee ku taxan ASTM A240.
Dhammaan cabbirrada waxay u baahan yihiin badeecooyin isku dhafan oo aan lahayn bir buuxin.Tilmaamaha sida ASTM A270, ASTM A269 iyo AS 1528 ayaa sidoo kale lagu dabaqaa alaabada aan cillad lahayn.
AS 1528 waxay qeexaysaa dhumucda magaca ah ee 1.6 mm dhammaan dhexrooryada dibadda (OD) marka laga reebo 2 mm OD 203.2 mm;dhumucyada kale waxaa lagu qeexi karaa iibsadaha.Dulqaadka caadiga ah + eber, -0.10 mm.Dulqaadka taban ee buuxa wuxuu la jaan qaadayaa dhaqanka caadiga ah ee soo saarista tubooyinka dhammaan cabbirrada oo u dhow dhammaadka hoose ee xadka dulqaadka.Qiyaasta caadiga ah waa 1.52 ilaa 1.58 mm.Dulqaadkani waxa kale oo uu khuseeyaa qalabka lagu rakibo.
* Dulqaadyada ASTM A554 xaaladaha alxanka.* AS1528 waxay sidoo kale khuseysaa cabbirada OD 12.7, 19.0, 31.8, 127.0, 152.4 iyo 203.2 mm.
Dhammaan tilmaamahan tuubooyinka waxay qeexayaan xadka dhumucda derbiga iyo dhexroorka ka baxsan.Dhexroorka gudaha si gaar ah looma cayimin.
Tilmaamaha daaweynta dusha sare ee cabbirro kala duwan oo lagu taliyay in lagu isticmaalo warshadaha cuntada ee Australia waa sida soo socota:
Habaynta alaabooyinka loo isticmaalo warshadaha cuntada waxay u baahan yihiin tubooyinka aan lahayn hadhaaga alxan ee dusha sare ee gudaha.
Astaamaha makaanikada ee darajooyinka kala duwan ee birta sida caadiga ah loo isticmaalo warshadaha cuntada waa sida soo socota:
AZoM waxay la hadlaysaa Maamulaha Guud ee NanoGraf Francis Wang si ay ugala hadlaan tignoolajiyada cusub ee baytariyada Lithium Ion iyo soo saarida wax soo saarka ee Midwest.
AZoM waxay la hadashay Dr. Katharina Marquardt ka hor Maalinta Caalamiga ah ee Haweenka iyo Gabdhaha Sayniska ee 2023. Waxaan ka wada hadalnay xirfadeeda cajiibka ah ee STEM ee khibradeeda ku saabsan maaddooyinka u dhexeeya macdanta ilaa alaabta dhoobada.
Maalinta Caalamiga ah ee Haweenka iyo Gabdhaha Sayniska, AZoM waxay kala hadashaa cilmi-baaristooda STEM iyo xirfadahooda Dr. Debrupa Lahiri, Ku-xigeenka Professor of Metallurgy iyo Sayniska Qalabka ee IIT Roorkee.
Dib u eegista badeecadan ee Microtrac waxay qeexaysaa awoodaha xayeysiinta teknoolojiyadda sare ee Belsorp Max X.
APEX 400 waa xal u go'an oo loogu talagalay diyaarinta gacanta ee kuullaha falanqaynta XRF.Waxay riixi kartaa muunado siddooyin bir ah oo la taageeray iyo sidoo kale cabbirrada caadiga ah ee aan la taageerin.
Baro wax badan oo ku saabsan sida loo kordhiyo waxtarka shaybaadhkaaga LabVantage 8.8, oo ah shabakad ganacsi oo shabakadeed si loo helo dhammaan macluumaadka shaybaadhkaaga.
Suuqa semiconductor-ka caalamiga ah wuxuu galay xilli xiiso leh.Baahida tignoolajiyada chip-ka ayaa labadaba kicisay oo dib u dhigtay horumarka warshadaha, yaraanta hadda jirta ayaa la filayaa inay sii socoto in muddo ah.Isbeddellada hadda jira waxay u badan tahay inay qaabeeyaan mustaqbalka warshadaha maaddaama ay tani sii socoto
Farqiga ugu weyn ee u dhexeeya baytariyada graphene ku salaysan iyo baytariyada adag-state waa ka kooban ee electrodes.Inkasta oo cathodes inta badan la beddelo, allotropes of carbon sidoo kale waxaa loo isticmaali karaa in lagu sameeyo anodes.
Sanadihii la soo dhaafay, Internetka Waxyaabaha ayaa si degdeg ah looga hirgeliyay ku dhawaad ​​dhammaan aagagga, laakiin waxay si gaar ah muhiim ugu tahay warshadaha gawaarida korontada.
