Ma pulses ali ndi encoded, ndipo mphamvu zowunikira zimatha kuwongolera kuyankha kwa mizinga, potero zimalepheretsa kusokoneza kwa mizinga ndi zopinga zokhazikitsidwa ndi mdani. Mwachitsanzo, bomba lankhondo laku US la GBV-15 Glide lotchedwa "bomba lanzeru". Mofananamo, itha kugwiritsidwanso ntchito kupanga zipolopolo zoyendetsedwa ndi laser.

6.3 Kulumikizana kwa laser

Kuphatikiza pa Nd · YAG ikhoza kugwiritsidwa ntchito polumikizana ndi laser, kutulutsa kwa laser kwa lithiamu tetra Neodymium(III) phosphate crystal (LNP) ndi polarized komanso yosavuta kusinthira. Imaonedwa kuti ndi imodzi mwazinthu zodalirika kwambiri zama laser, zoyenera kuwala kolumikizana ndi kuwala kwa fiber, ndipo zikuyembekezeka kugwiritsidwa ntchito muzolumikizana zophatikizika ndi kulumikizana kwamlengalenga. Kuphatikiza apo, Yttrium iron garnet (Y3Fe5O12) kristalo imodzi imatha kugwiritsidwa ntchito ngati zida zosiyanasiyana za magnetostatic surface wave ndi njira yophatikizira ma microwave, zomwe zimapangitsa kuti zidazo zikhale zophatikizika komanso zocheperako, ndipo zimakhala ndi ntchito zapadera mu radar remote control ndi telemetry, navigation and countermeasures zamagetsi.

Kugwiritsa Ntchito 7 Rare Earth Superconducting Materials mu Modern Military Technology

Pamene zinthu zimakhala zotsika kuposa kutentha kwina, chodabwitsa chakuti kukana ndi zero, ndiko kuti, Superconductivity, kumachitika. Kutentha ndi kutentha kwakukulu (Tc). Superconductors ndi antimagnets. Kutentha kukakhala kocheperako kuposa kutentha koopsa, ma superconductors amathamangitsa mphamvu ya maginito iliyonse yomwe imafuna kugwiritsa ntchito. Izi ndi zomwe zimatchedwa Meissner effect. Kuonjezera zinthu zapadziko lapansi zosowa kwambiri kuzinthu zopangira ma superconducting kumatha kukulitsa kutentha kwakukulu kwa Tc. Izi zalimbikitsa kwambiri chitukuko ndi kugwiritsa ntchito zida za superconducting. M'zaka za m'ma 1980, United States, Japan ndi maiko ena otukuka motsatizana anawonjezera kuchuluka kwa lanthanum, yttrium, europium, erbium ndi ma oxides ena osowa padziko lapansi ku Barium oxide ndi Copper (II) oxide compounds, zomwe zinasakanizidwa, kukanikizidwa ndi sintered. kupanga zida za ceramic za superconducting, zomwe zimapangitsa kugwiritsa ntchito kwambiri ukadaulo wa superconducting, makamaka pazankhondo, mokulirapo.

7.1 Superconducting mabwalo ophatikizika

M'zaka zaposachedwa, mayiko akunja achita kafukufuku wogwiritsa ntchito ukadaulo wapamwamba kwambiri pamakompyuta apakompyuta, ndikupanga mabwalo ophatikizika a superconducting pogwiritsa ntchito zida zadothi za superconducting. Ngati dera Integrated ntchito kupanga superconducting makompyuta, osati ndi kukula kochepa, kulemera kuwala, ndi yabwino ntchito, komanso ali ndi liwiro kompyuta 10 kwa 100 nthawi mofulumira kuposa makompyuta semiconductor.
