Uniaxial crystals yog cov khoom siv kho qhov muag nyob rau hauv uas lub refractive index ntawm ib tug siv lead ua axis txawv ntawm lwm cov siv lead ua axes (ie ni≠ nj=nk).
Yuav ua li cas yog uniaxial siv lead ua piv txwv?
Cov siv lead ua no tau piav qhia los ntawm ib qho kev kho qhov muag thiab ob lub ntsiab lus tseem ceeb refractive. Piv txwv ntawm uniaxial Crystals yog calcite, KDP, quartz, rutile thiab lwm yam. Thaum lub teeb ci hla dhau los ntawm cov siv lead ua, nws tawg mus rau hauv o-ray thiab e-ray >>.
Dab tsi yog uniaxial thiab biaxial crystals?
Ib lub siv lead ua uas tsuas muaj ib qho optic axis hu ua uniaxial siv lead ua. … Ib tug siv lead ua uas tsuas muaj ob lub optic axis hu ua biaxial crystal. Lub refractive index ntawm cov duab hluav taws xob zoo ib yam yog qhov tsis tu ncua rau txhua qhov kev taw qhia hauv cov siv lead ua, thiab ntawm cov duab hluav taws xob txawv txawv yog qhov sib txawv thiab nyob ntawm qhov kev taw qhia.
Koj ua li cas thiaj txiav txim siab tias cov ntxhia yog uniaxial lossis biaxial?
Yog tias muaj qhov curvature rau isogyre, cov ntxhia yog biaxial. Yog hais tias lub isogyre ncaj, ces cov ntxhia yog biaxial nrog ib tug tsawg 2V los yog uniaxial.
Yuav ua li cas yog uniaxial symmetry?
Hauv optical crystallography, cov anisotropic crystals muaj ib qho kev taw qhia ntawm pom meej isotropy, i.e., ib qho optic axis, sib xws rau cov kev taw qhia tshwj xeeb ntawm axial symmetry hauv hexagonal, trigonal, thiab tetragonal siv lead ua tshuab.
