Yintoni umahluko phakathi kwe-iPhone 9D kunye ne-9H yefilimu enomsindo?

I-9H ibhekisela kubunzima kwaye i-9D ibhekisela kwi-curvature ye-membrane.
Kodwa akukho 9D yokwenyani, nokuba zingaphi na iifilimu ezinomsindo we-D ezahlulwe kuphela zaba ngamagophe amathathu: inqwelomoya, i-2.5D, kunye ne-3D.
I-9H ibhekisela kubunzima, okwenene bubhekisela kubunzima bepensile, kungekhona ukuqina kwe-Mohs.Nokuba isiqwenga seglasi sinokugqitha obu bunzima, obukwayigimmick yokuthengisa.

Ukuqina kohlulwe ngokwe:
1. Ukukrwela ukuqina.Isetyenziselwa ikakhulu ukuthelekisa iqondo lokuthamba kunye nobulukhuni beeminerali ezahlukeneyo.Indlela yokukhetha intonga enesiphelo esinye esinzima kwaye esinye sithambile kwelinye, kwaye ukrwele izinto ezivavanyiweyo ecaleni kwentonga, kwaye ujonge ukuthamba kunye nokuqina kwempahla evavanyiweyo ngokwendawo yokukrala.Xa sithetha ngokomgangatho, imikrwelo eyenziwe zizinto ezilukhuni inde, kwaye imikrwelo eyenziwe zizinto ezithambileyo iba mfutshane.
2. Cinezela-kubulukhuni.Ikakhulu isetyenziselwa izinto zetsimbi, indlela kukucinezela i-indenter echaziweyo kwizinto ezivavanyiweyo kunye nomthwalo othile, kwaye uthelekise ubunzima bezinto ezivavanyiweyo kunye nobukhulu be-deformation yeplastiki yendawo kumphezulu wezinto eziphathekayo.
Ngenxa yomahluko we-indenter, umthwalo kunye nobude bexesha lomthwalo, kukho iintlobo ezininzi zobunzima bokungena, ubukhulu becala ukuqina kweBrinell, ukuqina kweRockwell, ubulukhuni beVickers kunye nobunzima obuncinci.

3. Phinda ubophe ubulukhuni.Ikakhulu isetyenziselwa izinto zetsimbi, indlela kukwenza isando esikhethekileyo esincinci siwe ngokukhululekileyo ukusuka kumphakamo othile ukuchaphazela isampulu yezinto eziza kuvavanywa, kwaye usebenzise isixa samandla oxinzelelo agcinwe (kwaye akhululwe) yisampuli ngexesha lovavanyo. inkqubo yempembelelo (ngokubuya kwesando esincinci).jump height determination) ukumisela ubulukhuni besixhobo.
Indlela yokuvavanya ubulukhuni be-Rockwell yi-SP yaseMelika ecetywayo nguRockwell ngo-1919, ngokusisiseko iyoyisa iziphene ezikhankanywe ngasentla zovavanyo lweBrinell.I-indenter esetyenziselwa ubulukhuni be-Rockwell yikoni yedayimane ene-angle ye-taper ye-120 ° okanye ibhola yentsimbi enobubanzi obuyi-1/16 intshi (i-intshi eyi-1 ilingana ne-25.4 mm), kwaye ubunzulu bokulinganisa busetyenziswa njengesiseko sokulinganisa ubulukhuni. ixabiso.
