Kusvikira zuva rino zvinoita sekunge hurumende yeChinese yakatsunga kuve piyona mune chero mhando uye nzvimbo yehupenyu. Nekuda kweizvi hazvishamise kuti rinenge vhiki rega rega tinofanirwa kutaura nezverumwe rudzi rwehunyanzvi ruzivo rwuchangobva kuburitswa. Pane ino chiitiko, pachinzvimbo chekutishamisa isu nerumwe rudzi rwekupenga kwenzvimbo kana nezvekuti sei ayo mamwe emarudzi mazhinji akasvika pakumakiswazve, tinofanirwa kutaura nezve chimwe chinhu chingangotinetsa isu zvakanyanya uye ndizvozvo China yakasarudza kuve mutungamiri munyika yevarwi.
Tichienda mune zvakadzama zvishoma, kure nekutaura nezvekuti murwi akashongedzerwa nezvombo zvakati, isu tichatanga nekugadzirisa nyaya yakakosha seyekuti mainjiniya vari kutarisira kuita chirongwa vakasarudza kuita kushandiswa kwekuzivikanwa se metamaterials pakuvakwa kwayo, chimwe chinhu chinogona kuita mamwe mauto asara ave nechidimbu chekuchinja pakarepo varwi vavo nekuda kwematambudziko ayo anogona kuvaunzira.
China inopa murwi wayo mutsva weJ-20, mhando isingaonekwe
Kana isu tichitaura nezvevarwi, zvirokwazvo pfungwa dzako dzinoenda kune idzo dzinoyevedza F-22 kana F-35 mamodheru, kune zvimwe zvikonzero kana zvimwe, kunyangwe mumwedzi ichangopfuura imwe nhevedzano yezvinhu zvitsva zvakaunzwa senge iyo KJ-600, iyo pachayo iyo yakavimbisa kuve kutya kweavo vese vanoviga varwi chaizvo nekuda kweiyo inoshamisa yekuona tekinoroji iyo iyo yakapihwa chipo. Ino inguva yekuona kana iyi KJ-600 ichigona kuona mhando senge J-20 yakangounzwa neChina, muenzaniso wakagadzirwa chaizvo kuti usaonekwe.
Chinangwa chikuru chakagadzwa nema mainjiniya echiChinese kwave kugadzira nekugadzira ndege inokwanisa isingaonekwe neazvino masisitimu uye mapuratifomu inowanikwa kumauto akasiyana. Sezvo iwe uchinyatso kuziva, isu tiri kutaura nezve yekucheka-kumucheto tekinoroji iyo isingawanikwe kune chero mugari, tekinoroji iyo yakagadziriswa imwe chete uye chete yeuto remauto uye iyo inogona kuita, sezvakaratidzwa, kuti hondo inopedzisira yakundwa mukwikwidzi kana mumwe.
Chii chinonzi metamaterial? Chii chaingashandiswa?
Parizvino iwe unenge wanzwa, mune imwe nharaunda kana imwe, taura nezve metamaterials, kunyanya nekuti inogona kuve inonakidza kwazvo, nekuda kwehunhu hwayo hwakasiyana, inoshandiswa mukuvaka kwema micro-marobhoti kana nanorobots. Kuenda mune zvakadzama zvishoma, ndikuudze kuti tiri kutaura nezvazvo zvishandiso zvakagadzirwa zvakagadzirwa iyo midziyo isingawanikwe mune zvakasikwa. Panguva ino, zvinofanirwa kucherechedzwa kuti zvishandiso zvakatogadzirwa izvo zvine zvivakwa zvinonakidza sekugona kuverenga kana kuziva mapatani akareruka.
Panyaya chaiyo yemurwi weChinese mutsva, kubva pane zvishoma zvatinoziva, metamaterials yakashandiswa mune imwe mhando ye kuumbwa kwesimbi nemapurasitiki iyo ine geometry yekugadzira kukanganisa mavelengths ezvese magetsi emagetsi nemanzwi uye mafungu emagetsi. Sehuwandu, ndikuudze kuti chinhu chitsva ichi chicha shandiswa zvakare mukugadzira antenna, izvo zvinogona kukonzera kugadzirwa kwe mamwe radar chaiwo ane huwandu hwakakura.
Chechipiri, uye ndipo panotaridzika kuti mhando yezvinhu iyi inonakidza mukugadzirwa kwechizvarwa chitsva chevarwi, idzi metamaterials dzakashandiswa kune kugadzirwa kwezvinotora. Pfungwa ndeyekuti iyi nyowani mhando yematamaterial inogona kushandiswa senge mhando ye 'musungo'zvekuti radars yemuvengi haigone kuona murwi, achitora mukana wekuti chinhu ichi chinogona kusvika tora mamwe wavelengths. Sezvinei uye uye maererano nerumwe ruzivo, chinhu ichi muzvikamu zvendiza, senge zvakadzikama zvinodzikamisa, zvikamu zvezvombo kana injini dzemagetsi, izvo zvinogona kuratidza masaisai eradar.
