Ndi kusintha kosalekeza kwa kuphatikiza zida za kompyuta, momwe kutentha kumatayikira kukukhala kofunika kwambiri. Chip yofanana ndi msomali imaphatikiza ma transistors okwana mamiliyoni khumi. Ubwino wa...

Kuyaka kwa catalytic ndi njira yonse ya okosijeni ya mafuta pamwamba pa chothandizira. Panthawi ya kuyaka kwa catalytic, ma reactants amapanga ma free radicals otsika mphamvu pamwamba pa chothandizira, ndikupanga kugwedezeka...

Zipangizo za thovu lachitsulo zimakhala ndi ma porosity osiyanasiyana (70%-98%), kukula kwa ma pore (100u-1000u) komanso kulondola kwa kusefera. Ma voids a zinthu za fyuluta yachitsulo yokhala ndi thovu ndi osiyana ndi a zinthu za fyuluta yachitsulo yokhala ndi thovu. Mabowo odutsa ...

Kodi kusiyana pakati pa thovu ziwiri zachitsulo, thovu la mkuwa ndi thovu la nickel ndi kotani? 1. Makhalidwe ndi ubwino wa thovu la mkuwa Choyamba, tiyeni tiwone momwe thovu la mkuwa limagwirira ntchito komanso momwe limagwirira ntchito; mu ...

Monga tonse tikudziwa, zinthu monga siponji, pulasitiki yokhala ndi thovu, rabala ndi matabwa nthawi zambiri zimasankhidwa ngati zinthu zotetezera komanso zoteteza kugundana m'moyo weniweni. Monga chimodzi mwa zinthu zachitsulo zomwe zimakhala ndi mapokoso, kodi ubwino wake ndi wotani woyamwa mphamvu zake komanso...

Kutaya kutentha kwa chipinda cha nthunzi ya vacuum ndi njira yatsopano yotaya kutentha. Chipinda cha nthunzi ya vacuum chingaonedwe ngati chopangidwa pogwiritsa ntchito chitoliro chotenthetsera. Ngakhale chitoliro chotenthetsera chingathandize kutentha kutumizidwa kunja kwa...

Thovu lachitsulo lili ndi mawonekedwe a malo akuluakulu apadera, kusinthasintha kwabwino komanso kutentha kwambiri, komanso lili ndi mphamvu zabwino za hydromechanical. Lili ndi ubwino waukulu kwambiri pakuchitapo kanthu kwa mpweya ndi zakumwa. Mu ...

Monga tonse tikudziwa, LED ndi gwero la kuwala lothandiza kwambiri, ndipo okonza mapulani amalikonda chifukwa cha kukula kwake kochepa. Koma amatha kutchedwa "ang'onoang'ono" pokhapokha ngati palibe kayendetsedwe ka kutentha komwe kakugwiritsidwa ntchito. Ngakhale poyerekeza ndi nyali zoyatsira magetsi,...

Zipangizo za thovu zili ndi magawo asanu akuluakulu: 1. Chitsulo chachitsulo, ndiko kuti, zinthu zachitsulo zomwe thovu lachitsulo lopangidwa ndi porous, kuphatikizapo nickel yopangidwa ndi thovu, mkuwa, chitsulo, aloyi yachitsulo-nickel, aloyi ya mkuwa-nickel, ndi pamwamba...

Kugwiritsa ntchito aluminiyamu yozungulira yokhala ndi mapokoso Aluminiyamu yozungulira yokhala ndi mapokoso ndi chitsulo chokhala ndi kuchuluka kwake, kukula kwake kwa mapokoso ndi mapokoso enaake mu matrix ya aluminiyamu. Ndi mtundu watsopano wa kapangidwe kake kosamalira chilengedwe...

Thovu lachitsulo limagwiritsidwa ntchito kwambiri m'munda wa zamoyo kupanga mafupa opangidwa; Komanso, thovu lachitsulo lingagwiritsidwenso ntchito m'munda wa zipangizo za batri, zomwe zimawonjezera kwambiri mphamvu ya mabatire. Kuphatikiza apo, m'munda wankhondo, ...

Kulemera kochepa komanso kopepuka: kuchuluka kwa aluminiyamu ndi 0.5-1.1g/cm3, poyerekeza ndi aluminiyamu wokhuthala, kuchuluka kochepa kwambiri ndi pafupifupi 25% ya aluminiyamu; Kukana kutentha: kutentha kogwirira ntchito kumatha kufika 300℃; Kukana kukhudza: osati kolunjika ...
