Tsis sib xws . Ob kab los yog cov duab uas lieexactly rau saum ib leeg. Piv txwv li: ob qho no kab yog coincident , koj xwb ua tau 'tsis pom lawv ob leeg, vim lawv yog sib sau!
Tsis tas li ntawd, koj yuav ua li cas thiaj paub tias kab yog coincident?
Parallel Kab yog kab uas yeej tsis cuam tshuam. Ob tug nonvertical kab yog thaum uas tig mus yog thiab xwb yog lawv muaj tib txoj kab nqes. Ob kab hais tias lion saum ib leeg yog hu ua coincident kab . Kab uas intersect nyob rau hauv ib tug point yog hu ua intersecting kab.
Tsis tas li ntawd, muaj pes tsawg txoj kev daws teeb meem yog kab sib npaug? Thaum peb ntsuas lawv, lawv yog ib qho kab , coincident , txhais tau tias lawv muaj tag nrho cov ntsiab lus nyob rau hauv common. Qhov no txhais tau hais tias muaj ib tug infinite tus naj npawb ntawm kev daws teeb meem qhov system. Vim qhov no system muaj yam tsawg kawg ib daws nws raug suav hais tias yog qhov sib xws. Consistentsystems yog systems uas muaj yam tsawg kawg ib daws.
Ua kom pom qhov no, puas cov kab sib txuam puas muaj kev daws teeb meem?
Yog hais tias ib kab yog ib tug ntau ntawm lwm yam, lub kab yog coincident thiab muaj tag nrho cov ntsiab lus sib xws. Yog hais tias txhua kab hauv qhov system muaj tib txoj kab nqes tab sis sib txawv-intercept, lub kab yog parallel thiab tsis muaj daws . Yog tias txhua kab hauv qhov system muaj tib seemlope thiab tib y-intercept, lub kab yog coincident.
Nws hu li cas thaum ob kab yog tib yam?
Ob kab intersect thaum lawv hla ib leeg. Lawv tsim vertically opposite ces kaum, uas peb yuav kawm tom qab. Qhov point qhov twg kab kev sib tshuam yog hu ua lub ntsiab lus ntawm kev sib tshuam. Yog hais tias cov ces kaum tsim yog tag nrho cov kaum sab xis, lub kab yog hu ua perpendicular kab.
Pom zoo:
Dab tsi yog qhov txawv ntawm kab rau kab voltage thiab kab rau nruab nrab voltage?
Qhov voltage ntawm ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem rau theem) voltage. Qhov voltage hla txhua qhov winding (piv txwv li ntawm 'L1' thiab 'N' yog hu ua kab rau nruab nrab (lossis theem voltage)
Nws txhais li cas los sau koj cov lus teb nyob rau hauv cov nqe lus ntawm pi?
Cov lus teb meej txhais tau tias koj tsis xav tau lub tshuab xam zauv, tsuas yog tso koj cov lus teb kawg uas qhia txog Pi. Lub voj voog ntawm lub voj voog tuaj yeem pom siv cov qauv C = Pid. C yog qhov ncig (qhov perimeter) thiab d yog txoj kab uas hla. Yog li hauv paus koj tsuas yog yuav tsum tau muab txoj kab uas hla los ntawm Pi
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Koj ua pov thawj li cas ob kab yog coincident?
Yog hais tias ib kab yog sau li Ax + By = C, lawv-intercept yog sib npaug rau C / B. Yog hais tias txhua kab hauv qhov system muaj tib txoj kab nqes tab sis sib txawv y-intercept, cov kab sib npaug thiab tsis muaj kev daws teeb meem. Yog hais tias txhua kab nyob rau hauv lub system muaj tib txoj kab nqes thiab tib y-intercept, cov kab yog coincident
