Mu bizinesi yathu yamafuta ndi gasi, kupanga kwatsika ndi 8% pachaka m'gawo loyamba. Zifukwa zikuphatikiza kutsika kwachilengedwe komanso kukonza mwachangu ndi ntchito, zomwe zikuchitika kuti zithandizire kudalirika kwa katundu kuti akwere bwino m'malo otsatirawa. Pochita izi tsopano, tikuwonetsetsa kuti tili ndi theka lachiwiri lamphamvu mpaka chaka chino pomwe zina mwazinthuzi zikubwera.

Kafukufuku wasonyezanso kuti zinyalala zachikopa zimawononga dothi lapamwamba la Hazaribagh. Kafukufuku wa 1999 adapeza kuipitsidwa ndi zitsulo zosiyanasiyana, kuphatikiza lead ndi cadmium. Anamaliza kuti:

Mapangidwe ndi mawonekedwe a mawonekedwe opangidwa pa Al electrode mu AlCl3-IL electrolyte (Tal electrode) adafunsidwa pogwiritsa ntchito mawonekedwe owoneka bwino-Mawonekedwe anayi akusintha ma infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), energy-dispersive x -ray spectroscopy (EDX), ndi x-ray photoelectron spectroscopy (XPS). Poyerekeza ndi Al koyera, pamwamba pa Tal amalemeretsedwa ndi organic zinchito magulu (mkuyu 1A). Kuphatikiza pa kukhalapo kwa magulu a C = N ndi C-H omwe alinso ochuluka mu pristine IL electrolyte, kuwonjezereka kwakukulu mu gulu la C=C logwira ntchito ndi kutuluka kwa zamoyo zomwe zili ndi gulu la C = O zimadziwika pa Tal. Zowonera izi zimatsagana ndi mawonekedwe a filimu yokhazikika pamtunda wa Tal. Komanso, infuraredi kugwedera modes kugwirizana ndi mphete imidazolium (1100 kwa 600 cm−1) mu IL (21) makamaka kutha pa mankhwala, zomwe zimasonyeza kuti IL electrolyte amasinthidwa mankhwala pa Al interface (mkuyu 1A). Kuwunika kwa XPS kwa pristine Al ndi Tal kumapereka zidziwitso zowonjezera pazamankhwala apamwamba a TAl. Zotsatira mu Mkuyu 1B, mwachitsanzo, zimasonyeza kuti ngakhale pambuyo popukuta, Al2O3 imalamulirabe chemistry yapamwamba ya pristine Al. Mosiyana ndi izi, mawonekedwe a Al2p XPS a gawo lapansi la Tal amawulula kuti gulu lomwe lili ndi mphamvu zomangira zambiri, zomwe zitha kukhala chifukwa cha mchere wa Al, mwina AlCl3, ndiwolamulira. Izi zimatsimikiziridwa ndi mawonekedwe a Cl2p XPS, chifukwa mphamvu yomangirira ya Cl2p yomwe ili pafupi ndi 199 eV imagwirizana ndi valence ya -1 (mkuyu 1C). Mawonekedwe a N1s XPS amawonetsanso kuti mawonekedwe a Tal ali ndi mitundu yokhala ndi nayitrogeni. The lakuthwa pachimake pa 401 eV angagwiritsidwe ntchito mosakayikira kudziwa pamaso pa imidazole ayoni (mkuyu. 1D). Poyerekeza ndi pristine opukutidwa Al pamwamba (mkuyu. 1E), pamwamba topography wa Tal mwachionekere yosalala (mkuyu. 1F). Kuchokera pamawonekedwe agawo ojambulidwa ndi SEM, mawonekedwe ophatikizika amawonedwa pa gawo la Al. Kusanthula kwa EDX kwa wosanjikiza kumasonyeza kuti ndi olemera mu zinthu Al, Cl, ndi N (Mkuyu 1G ndi mkuyu. S1).

Bicycle yatsopano ya miyala ya WI.DE (Winding Detours) yochokera ku Open imatenga matayala okulirapo kuposa UP yoyambirira ya kampani kuyambira 2015 ndipo ndiyabwinoko, yothamanga kwambiri pamtunda wamitundu yonse, wophatikizidwa ndi kuwongolera kwakukulu komanso kulemera kochepa kuchokera ku choyambirira izo zakhazikitsidwa. Koma mtengo wamtengowo umayika malire kwa ambiri ndipo mutha kungogula ngati chimango chosankha mtundu umodzi.

Vosko, SH, Wilk, L. & Nusair, M. Mphamvu zolondola za ma elekitironi ogwirizana ndi spin-dependent for the local spin-density calculations - kusanthula kovuta. Mutha. J. Phys. 58, 1200-1211 (1980).

Mfundo zina za owononga wamba ndi gasi wogwiritsidwa ntchito. Pamenepa ndodo za aluminiyamu (zo aluminiyamu) zimakhala zotentha kwambiri kuti zigwiritse ntchito masilinda a gasi otsika mtengo ndipo MAP Pro (m'malo mwa MAPP) mwina ndi yabwinoko pang'ono kuposa Propane bola ngati kutentha kukumira kutentha kwanu sikuli kwakukulu kwambiri.

Pali anthu pafupifupi 8,000 mpaka 12,000 ogwira ntchito zofufuta zikopa, zomwe zikuwonjezeka kufika pa 15,000 kwa miyezi iwiri kapena itatu kutsatira chikondwerero cha Eid-al-Adha, nyengo yapamwamba kwambiri yokonza zikopa.[3]

GMAW mu aluminiyamu ndiyofala kwambiri m'malo opanga zinthu zambiri…GTAW ndiyofala kwambiri pamagwiritsidwe ntchito achikhalidwe.

Mitengo yamatabwa, zingwe zamatabwa, chilichonse chomwe mungachitchule, kapangidwe kake kali pano kuti kakhale mkati mwa Singapore.

Chithunzi cha S9. Electrochemical properties of Al-MnO2 mabatire ntchito Tal anode–, Al(CF3SO3)3-, ndi Al2(SO4)3-based aqueous electrolyte.

Mulingo umenewo ukhoza kufika 300kg/600lbs. Sindimayembekezera kuti kulumikizana kukhale kolimba kotero kuti kukhazikitsidwa kwanga sikunakonzekere. Ndikufuna kupanga popachika poyesa zinthu ngati izi m'tsogolomu. Ndikuganiza kuti mukuphonya mfundo ya kanema wanga. Anthu ambiri safuna malumikizidwe amphamvu mokwanira kuti akoke machubu a CF mu 2. Ndangopanga njira yosavuta yopangira nsonga za ndodo zomwe zimakhala zolimba kwambiri pamapulojekiti osangalatsa/ma robotiki.

Ngati mukufuna munthu wokwera komanso kuchita zachilendo, koma osafuna kuwononga ndalama zambiri, Metrix ndi njira yabwino.
