Uniaxial cov zaub mov yog chav kawm ntawm anisotropic cov ntxhia uas suav nrog tag nrho cov ntxhia uas crystallize hauv tetragonal thiab hexagonal crystal systems. Lawv hu ua ib uniaxial vim hais tias lawv muaj ib tug optic axis. Rau uniaxial cov zaub mov cov ob qhov tseem ceeb ntawm qhov ntsuas qhov cuam tshuam tau txhais ua ω (lossis No) thiab ε (lossis Ne).
Kuj nug, dab tsi yog biaxial ntxhia?
Txhua cov ntxhia uas crystallize hauv orthorhombic, monoclinic, lossis triclinic siv lead ua tshuab yog biaxial . Zoo li uniaxial crystals, biaxial muaju muaj qhov ntsuas qhov cuam tshuam uas sib txawv ntawm ob qhov kev kub ntxhov, tab sis kuj tseem muaj qhov tshwj xeeb nruab nrab qhov cuam tshuam qhov ntsuas.
Ib tus kuj tseem yuav nug, dab tsi yog uniaxial thiab biaxial siv lead ua? Uniaxial vs Biaxial Crystals A uniaxial siv lead ua yog ib qho khoom siv kho qhov muag uas muaj ib qho optic axis. A biaxial siv lead ua yog ib qho khoom siv kho qhov muag uas muaj ob txoj hauv kev kho qhov muag. Daim ntawv tsis zoo. Qhov tsis zoo uniaxial siv lead ua muaj qhov refraction index ntawm o-ray (no) loj dua li ntawm e-ray (ne).
Tsis tas li ntawd, puas yog quartz uniaxial zoo lossis tsis zoo?
Quartz belongs rau chav kawm trigonal crystal thiab raws li yog ib uniaxial . Nws yog hu ua uniaxial zoo vim ne > no. Optical axis nyob rau hauv quartz sib raug zoo rau c-axis ntawm chav nyob ntawm tes, yog li tsis muaj kev sib txuas lus thaum lub teeb hla cov siv lead ua los ntawm qhov taub mus rau qhov taub.
Koj yuav txheeb xyuas qhov kos npe kho qhov muag ntawm cov ntxhia li cas?
Cov optic kos npe ntawm cov ntxhia ua tau txiav txim siab los ntawm kev saib tus swb uas yog saib hauv qab qhov muag axis ua ntxhia . Hauv qhov no, yuav tsum muaj tus ntoo khaub lig dub uas txhua lub teeb tau ploj mus.

Dab tsi yog nrawm dua dab los yog Dodge Hellcat?
Thaum nws los txog rau lub caij muaj zog, ob lub Hellcat thiab Dab xa. Hellcat tuaj yeem mus los ntawm xoom mus rau 60 mais ib teev hauv 3.4 vib nas this, thaum Dab siv 2.3 vib nas this los txog ntawd. Thaum nws los txog rau peb-mais nrawm, Hellcat's yog 10.9 vib nas this thiab Dab yog 9.65 vib nas this
Dab tsi yog cov pab pawg sib ntaus sib tua xyaum ua dab tsi?
QHOV LOJ Kev sib ntaus sib tua hauv cov tub rog piav qhia yuav ua li cas platoons thiab pab pawg siv hluav taws thiab tswj kev ua rau muaj xwm txheej tshwm sim. Lawv xav kom cov thawj coj txiav txim siab sai sai thiab tshaj tawm cov lus txib luv luv sai
Dab tsi yog qhov sib txawv ntawm kev siv tas li thiab kev tsav tsheb cuam tshuam dab tsi?
Los ntawm kev sib piv, qhov cuam tshuam rau tus tsav tsheb tau nrawm dua thiab hnyav dua li tus qauv laum-tsav tsheb thiab feem ntau muaj lub zog ntau dua lossis sib zog. Cov txheej txheem xyaum ua haujlwm feem ntau yog siv rau qhov qhov drilling thiab tsav tsheb hauv cov khawm me me. Ib qho kev cuam tshuam rau tus tsav tsheb lub hom phiaj tseem ceeb yog kom tsav nrawm nrawm
Dab tsi yog qhov laj thawj thiab nws qhov tseem ceeb hauv qhov xwm txheej tsis saib xyuas yog dab tsi?
Qhov ua rau sib thooj yog kev ua, txawm tias txhob txwm ua lossis tsis saib xyuas, uas tau txiav txim siab ua rau lwm tus puas tsuaj, raug mob, lossis raug kev txom nyem. Nws yog ib qho tseem ceeb uas cov tsev hais plaub tsim kom muaj qhov xwm txheej ntawm tus kheej raug mob vim tsis yog txhua tus thiab txhua yam uas ua rau muaj kev raug mob tuaj yeem raug cai
Koj tsis muaj cov ntxhia dab tsi thaum koj muaj ceg caws?
Mineral depletion. Cov poov tshuaj tsawg heev, calcium lossis magnesium hauv koj cov zaub mov tuaj yeem pab ua rau cramps. Diuretics - cov tshuaj feem ntau tau qhia rau ntshav siab - kuj tseem tuaj yeem ua rau cov zaub mov no ploj mus
