Pasi pasirese inosimudzira maitiro ezvakadzika-carbon njere

Remangwana rasvika, uye vanhu vakadana zvishoma nezvishoma vakasvika munharaunda yakasvibira uye yakaderera-carbon.Rare pasiZvinhu zvezvinhu zvinobata basa rakakosha muzvivakwa zvemhepo, mota nyowani, marobhoti anehungwaru, hydrogen kushandiswa, kusimbisa simba kuponeswa, uye kunatsa-kunatsa.

Rare pasiizita rekudyidzana kwemasimbi 17, kusanganisiraytrium, Scandium, uye 15 lanthanide zvinhu. Mota yekutyaira ndiyo yakakosha chikamu chehungwaru marobhoti, uye basa rayo rakabatanidzwa rinonyanya kuwanikwa nemotokari yekutyaira. Nzvimbo isingaperi yemagrokronous servo motors ndiyo huru, inoda simba repamusoro kuti ratsi uye torque inerquia, yakakwirira inertia, uye yakaderera uye yakatsiga. Pakakura performance neodymium iron boron zvisingagumi magneti anogona kuita kuti kufamba kwerobhoti kuve nyore, nekukurumidza, uye kuwedzera simba.

Kune zvakare akawanda akaderera-carbon application yezvisingawanzo zvepanyikaMuchinyakare yemumotokari munda, senge girazi rinotonhora, kucheneswa kwakaneta, uye kusingaperi maglet. Kwenguva yakareba,cerium. Ehe, chinhu chakanyanya kukosha chinenge chinatsa gasi kucheneswa. Parizvino, nhamba huru yeceriumRadza Pasi Pasi Pasi Pasi Kuchenesa Vamiriri vanokwanisa kudzivirira huwandu hwakawanda hwemotokari yakanatswa gasi kubva pakubviswa mumhepo. Kune akawanda mashandisirwo emazuva ese epasi pasi mune yakaderera-kabhoni green technologies.

Zvisingawanzo zvepanyikainoshandiswa zvakanyanya nekuti ivo vane anonyanya kunaka thermoelectric, magineti, uye zvivakwa zvemagetsi. Iyo yakakosha yemagetsi chimiro inowana zvisingawanzo kuitika pasi nezvivakwa zvakapfuma uye zvine mavara, kunyanya kubvirarare pasiZvinhu zvine 4F Electron Sublyer, dzimwe nguva zvinozivikanwa zvakare se "esimba level". Iyo 4F Electron Sublayer isiri chete inoshamisa masimba manomwe esimba, asi zvakare ine "simba maviri" inodzivirira inovhara ye5D 5d uye 6s pane denghery. Aya magetsi manomwe esimba akaita kunge madhaimondi goourd madhora, akasiyana uye anonakidza. Magetsi asina kugadziriswa pamatanho manomwe esimba kwete chete anotenderera pachavo, asi zvakare orbit kutenderedza nucleus, kugadzira mamaiti akasiyana emagineti uye kugadzira magineti ane demo dzakasiyana. Aya micro minda minda inotsigirwa nezvikamu zviviri zvekudzivirira, kuita kuti vashatire mashnet. Masayendisiti anoshandisa maginism yevanotanga pasi simbi kuti vagadzire magneti akakwirira-mashandiro, zvakajeka se "zvisingawanzo kuitika magneti". Zvisinganzwisisike zvivakwa zvezvisingawanzo zvepanyikavachiri kuongorora uye kuwanikwa nemasayendisiti kusvikira nhasi.

Kunamatira neodymium magnets kuve nyore kuita, mutengo wakaderera, size diki, yakakwirira chaiyo, uye yakagadzikana yemagineti yemagineti. Ivo vanonyanya kushandiswa muminda yakadai sehunyanzvi ruzivo, hofisi yekuzvitakura, uye vatengi vezvemagetsi. Kupisa kwakamanikidza neodymium maglks ane zvakanakira llensity yakakwirira, kwakanyanya kutarisisa, kwakanaka kupesana, uye nekumanikidza kwakanyanya.

Mune ramangwana, nyika isingawanzoita basa rakakosha kwazvo mukuita kwekuvaka yakadzika-carbon ungwaru hwehukuru hwevanhu.
