1, kushongedzwa kwerunako rwemotokari - firimu;
Firimu ndiyo pfungwa yekutanga yevashandi vazhinji vemotokari itsva yekushongedza runako, firimu rinogona kuparadzanisa chiedza cheultraviolet, chiedza chezuva hachitungamiriri mukati memotokari, kuvanzika kuri nani. Zvinokurudzirwa kuti varidzi vatsva vasarudze membrane isingaputike. Firimu isingaputike ine maonero akasimba, zvisinei neruvara rwayo, yakajeka kubva kumotokari kuenda kunze, uye inogona kuchengetedza maonero akanaka husiku uye mumazuva ekunaya. Sarudzo yefirimu isingaputike inofanira kufunga nezvekujeka, kujeka uye mhedzisiro yekudzivirira;
Pamusoro pezvo, firimu remahwindo emota, kunyanya firimu remahwindo epamberi kumativi ese ehwindo, rinofanira kusarudza transmittance inopfuura 85% yakakodzera, saka firimu remahwindo eparutivi harifanirwe kuchera maburi uye harikanganisi mutsetse wekuona, kutyaira husiku kuenda kumashure kwemwenje yemotokari inopenya pagirazi rekumashure rechiedza chakasimba chinopenya chinopenya, kuitira kuti maziso anzwe akasununguka. Zvakakosha kusarudza membrane yakanaka, uye zvakakoshawo kusarudza chitoro chakanaka. Tekinoroji nemamiriro ekunze akapfava uye akaomarara efirimu anoda zvakanyanya. Semuenzaniso, nharaunda isina guruva, michina yakakosha, maitiro ekushanda akajairwa uye tekinoroji yehunyanzvi, nezvimwewo, saka, firimu harifanirwe kusarudza chitoro chemumugwagwa.
2, kushongedzwa kwerunako rwemotokari - mudziyo wekudzivirira kuba;
Kuchengetedzeka kwemotokari ndiko kwakanyanya kutarisirwa, saka varidzi vazhinji vezvigadzirwa zvekudzivirira kuba vachasarudza kuve nemidziyo, mota inogona kudzora gonhi iri kure, zviri nyore uye zvinoshanda. Sarudza zvigadzirwa zvemidziyo yekudzivirira kuba zvinofanira kutariswa kana kuburikidza nebvunzo dzedhipatimendi rakakodzera, kana kuratidza kwakabva chigadzirwa. Uyezve, pari zvino, vamwe vagadziri vanotengesa mamodheru akaisa sisitimu yekudzivirira kuba, saka havafanirwe kuisa zvigadzirwa zvekudzivirira kuba.
