Micro - kev xav Ib chav kawm ntawm linear distortions yog micro - kev xav , uas yog tshwm sim los ntawm impedance mismatches. Thaum muaj impedance tsis sib haum nyob rau hauv qhov nruab nrab kis tau tus mob los yog nyob rau hauv lub load, ib co ntawm cov teeb liab teeb liab lub hwj chim yog reflected rov qab mus rau qhov chaw.
Tsis tas li ntawd, dab tsi yog qhov kev xav hauv kev sib txuas lus cov ntaub ntawv?
Kev xav yog tus txheej txheem ntawm kev nkag mus rau cov ntaub ntawv hais txog kev thauj khoom sib dhos thiab cov hom uas tau hais tseg rau hauv los tsim, thov thiab nkag mus rau hom xwm txheej ntawm lub sijhawm ua haujlwm. Kev xav ua rau nws tuaj yeem saib cov ntaub ntawv sib dhos ntawm ib qho khoom xws li cov xwm txheej, cov khoom, txoj hauv kev thiab thaj chaw.
tilt cable yog dab tsi? Lub sij hawm qaij ” yog synonymous nrog kab kev faib tawm thiab hais txog qhov tseeb tias cov kab hluav taws xob ntau zaus attenuate sai dua nyob rau hauv cov kab coaxial trunk tshaj li qhov tsawg zaus raws.
Kuj Paub, dab tsi ua rau ripples hauv cable?
Impedance mismatch nyob rau hauv lub kab , kev ntsuam xyuas board traces, thiab pob ua rau ntau qhov kev xav ntawm electromagnetic teb, uas ua rau tsim ntawm ripples . Cov no ripples yog ua rau vim impedance mismatch ntawm junctions ntawm cov interconnects.
Koj txhais li cas los ntawm kev xav?
Kev xav yog thaum lub teeb bounces ntawm ib yam khoom. Yog hais tias qhov saum npoo yog du thiab ci, zoo li iav, dej los yog polished hlau, lub teeb yuav muaj kev cuam tshuam ntawm tib lub kaum sab xis thaum nws tsoo ntawm qhov chaw. Qhov no yog hu ua specular xav txog.

Sociobiology yog dab tsi thiab dab tsi yog qhov kev thuam loj ntawm nws?
Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Micro arc thib ob yog dab tsi?
Microarcsecond (plural microarcseconds) Ib chav ntawm lub kaum sab xis; ib lab (10-6) ntawm ib arcsecond
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
