Ngokuthuthuka okuqhubekayo kokuhlanganiswa kwezesekeli zekhompyutha, isimo sokushabalaliswa kokushisa siya ngokuya siba sibaluleke kakhulu. I-chip enobukhulu be-nail ihlanganisa ama-transistors afinyelela ezigidini eziyishumi. Ikhwalithi...

Ukushisa kwe-Catalytic kuyindlela ephelele yokusabela kwe-oxidation kaphethiloli ebusweni be-catalyst. Ngesikhathi sokusabela kwe-catalytic combustion, ama-reactants akha ama-free radicals angaphansi kwamandla aphansi ebusweni be-catalyst, akhiqize ukudlidliza...

Izinto ze-foam zensimbi zinezimbobo ezahlukahlukene (70%-98%), usayizi wembobo (100u-1000u) kanye nokunemba kokuhlunga. Izimbobo zezinto zokuhlunga zensimbi ezine-foam zihlukile kunezo zento yokuhlunga yensimbi ene-sintered. Izimbobo ezidlulayo ...

Uyini umehluko phakathi kwama-foam amabili ensimbi, i-foam yethusi kanye ne-nickel foam? 1. Izici nezinzuzo ze-foam yethusi Okokuqala, ake sibheke inqubo yokukhiqiza kanye nezici ze-foam efakwe i-foam;...

Njengoba sonke sazi, izinto ezifana nesiponji, ipulasitiki enegwebu, irabha kanye nokhuni zivame ukukhethwa njengezinto zokuvikela kanye nezinto zokulwa nokushayisana empilweni yangempela. Njengenye yezinto zensimbi ezinezimbobo, yiziphi izinzuzo zokumuncwa kwayo amandla kanye...

Ukushabalalisa ukushisa kwegumbi lomhwamuko we-vacuum kuyindlela entsha yokusabalalisa ukushisa. Igumbi lomhwamuko we-vacuum lingabhekwa njengelakhiwe ngokusekelwe kupayipi lokushisa. Nakuba ipayipi lokushisa lingasiza ukushisa ukuthi kuthunyelwe kwamanye amazwe...

I-foam yensimbi inezici zendawo enkulu ethile, i-ductility enhle kanye ne-thermal conductivity ephezulu, futhi inezakhiwo ezinhle ze-hydromechanical. Inezinzuzo ezibaluleke kakhulu ekuphenduleni kwe-catalytic kwamagesi noketshezi. Ku ...

Njengoba sonke sazi, i-LED ingumthombo wokukhanya osebenza kahle kakhulu, futhi iyathandwa abaklami ngenxa yobukhulu bayo obuncane. Kodwa empeleni ingabizwa ngokuthi "incane" kuphela uma ukuphathwa kokushisa kungahilelekile. Nakuba kuqhathaniswa nezibani ze-incandescent,...

Izinto zensimbi ye-foam zinamapharamitha amahlanu ayinhloko: 1. I-substrate yensimbi, okungukuthi, ukuthi iyiphi impahla yensimbi eyenziwe ngayo izinto ze-foam yensimbi enezimbobo, okuhlanganisa i-nickel ene-foam, ithusi, insimbi, i-iron-nickel alloy, i-copper-nickel alloy, kanye nokushisa okuphezulu...

Ukusetshenziswa kwe-aluminiyamu enezimbobo eziyindilinga I-aluminiyamu enezimbobo eziyindilinga iyinto yensimbi equkethe inani elithile, usayizi othile wosayizi we-pore kanye ne-porosity ethile ku-matrix ye-aluminiyamu. Luhlobo olusha lwesakhiwo esinobungani nemvelo...

I-foam yensimbi isetshenziswa kabanzi emkhakheni wezinto eziphilayo ukwenza amathambo okwenziwa; ngaphezu kwalokho, i-foam yensimbi ingasetshenziswa futhi emkhakheni wezinto zebhethri, okwandisa kakhulu ubuningi bamandla amabhethri. Ngaphezu kwalokho, emkhakheni wezempi, ...

Ubuningi obuphansi kanye nesisindo esilula: ububanzi bobuningi bungu-0.5-1.1g/cm3, uma kuqhathaniswa ne-aluminium eqinile, ubuningi obuphansi bungu-25% we-aluminium; Ukumelana nokushisa: izinga lokushisa lokusebenza lingafinyelela ku-300℃; Ukumelana nomthelela: hhayi njengokuqondiswa ...
