A kev sib hloov yog ib qho kev hloov pauv uas hloov daim duab nyob rau hauv ib qho clockwise los yog counterclockwise. Koj tuaj yeem tig ib daim duab 90 °, ib lub hlis twg tig, los yog clockwise los yog counterclockwise. Thaum koj tig daim duab raws nraim ib nrab, koj muaj tig yog 180°. Tig nws tag nrho txoj kev nyob ib ncig ntawm rotates daim duab 360 °.
Ntawm no, qhov taw tes ntawm kev sib hloov yog dab tsi?
Point ntawm kev sib hloov . Cov point ntawm kev sib hloov yog lub hauv paus taw tes nyob ib ncig ntawm uas ib daim duab yog tig.
Ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm kev sib hloov hauv lej? Kev sib hloov . Ib qho kev hloov pauv uas lub dav hlau daim duab tig ib ncig ntawm qhov chaw ruaj khov. Hauv lwm lo lus, ib qho taw tes ntawm lub dav hlau, qhov chaw ntawm kev sib hloov , yog tsau thiab txhua yam ntawm lub dav hlau tig txog qhov taw tes los ntawm lub kaum sab xis muab. Saib thiab.
Tsis tas li ntawd, qhov piv txwv ntawm kev sib hloov yog dab tsi?
Kev sib hloov yog tus txheej txheem los yog ua ntawm tig los yog ncig ib ncig ntawm ib yam dab tsi. Ib piv txwv ntawm kev sib hloov yog lub ntiaj teb orbit ncig lub hnub. Ib piv txwv ntawm kev sib hloov yog ib pawg neeg tuav tes hauv ib lub voj voog thiab taug kev tib yam.
Lub Center ntawm kev sib hloov yog dab tsi?
Nrog rau txhua qhov kev sib hloov, muaj ib qho chaw ruaj khov-hu ua qhov chaw ntawm kev sib hloov - nyob ib ncig ntawm uas txhua yam rotates. Los yog lub ntsiab lus tuaj yeem nyob sab nraud ntawm daim duab, nyob rau hauv rooj plaub no tus duab txav raws ib ncig arc (xws li lub orbit) nyob ib ncig ntawm qhov chaw ntawm kev sib hloov . Tus nqi tig yog hu ua kev sib hloov lub kaum sab xis.

Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
Yuav ua li cas koj txheeb xyuas cov kev sib txuas ntxiv thiab cov kab ntsug?
Cov kaum sab xis yog ob lub kaum sab xis nrog qhov sib npaug ntawm 90º. Cov ces kaum ntxiv yog ob lub kaum sab xis nrog qhov sib npaug ntawm 180º. Vertical angles yog ob lub kaum sab xis uas nws ob sab tsim ob khub ntawm opposite rays. Peb tuaj yeem xav txog cov no yog cov kaum sab xis uas tsim los ntawm X
Puas yog kev sib hloov kho qhov muag thiab kev sib hloov tshwj xeeb zoo ib yam?
Hauv chemistry, kev sib hloov tshwj xeeb ([α]) yog cov cuab yeej ntawm cov tshuaj chiral. Yog hais tias lub compound muaj peev xwm tig lub dav hlau ntawm polarization ntawm lub dav hlau-polarized lub teeb, nws tau hais tias yog "optically active". Kev sib hloov tshwj xeeb yog cov cuab yeej siv zog, qhov txawv ntawm qhov tshwm sim ntau dua ntawm kev hloov kho qhov muag
Koj yuav txheeb xyuas qhov kev sib raug zoo li cas?
Txhawm rau txiav txim siab qhov laj thawj koj yuav tsum ua qhov kev xeem randomization. Koj coj koj cov ntawv xeem, thiab xaiv ib nrab ntawm lawv kom muaj qhov zoo A thiab ib nrab kom tsis muaj nws. Tom qab ntawd koj pom tias muaj qhov sib txawv tseem ceeb hauv qhov zoo B ntawm ob pawg
Dab tsi yog qhov sib txawv ntawm qhov txheeb ze zaus thiab qhov xwm txheej txheeb ze?
Marginal txheeb ze zaus yog qhov piv ntawm cov lej ntawm qhov sib koom ua ke txheeb ze zaus hauv kab lossis kab thiab tag nrho cov ntaub ntawv muaj nuj nqis. Conditional txheeb ze zaus tus lej yog qhov sib piv ntawm qhov sib koom sib txheeb zaus thiab muaj feem cuam tshuam txog qhov sib txawv ntawm qhov sib txawv
