Peb yuav cov nyom thaum lub hnub nyoog 16800 koob yog li cas los laij nws? Kuv hauv qab no rau txhua tus neeg los coj ib txoj kab ntawm qhov ua ntsej nyom ntsej swb tawm ntawm qhov kev piav qhia:
Tig mus rau sab nraum qab ntawm cov nyom, uas yog hu ua ib pawg ntawm txhua koob. "Cluster density" yog hais txog cov nyom ib square meter, feem ntau 16800 koob / m2, 18900 koob / m2,22050 koob / m2.
"Cluster ntom" yog li cas los laij nws? Peb txhua tus paub tias thaj tsam ntawm qhov duab plaub yog multiplied los ntawm lub dav, yog li ntawd qhov "ntom ntom" yog xam tib yam nkaus.
Qhov ntev ntawm qhov "ntom ntom ntom" xam tau hais tias "cov xov tooj ntawm cov xov ntxiv", thiab tus xov tooj ntawm cov xov ntxiv yog 10 cm ntev, feem ntau yog 16-tus pin, 18-tus pin, 21-pin.
Qhov dav ntawm qhov "ntom ntom" yog hu ua "pitch", txij li thaum pib ntawm cov nyom qhuav tshuab, mas yog chav tsev yog taw. Feem ntau cov menyuam yaus siv cov nyom 3/8 taw, lossis 0.9525cm.
Muab ib qho piv txwv, siv sij hawm ntev ntawm ib ntu 1m ntawm "koob" rau 16-tus pin, txoj kab ntawm 3/8 taw ntawm cov nyom, nws yog 1 square metres. 1m yog sib npaug rau 100 cm, yog li qhov ntev ntawm ib lub meter nrog 160 koob. Dav dav ntawm 100 los ntawm 0.9525 rau 105 pob. Yog li ntawd cov kab ntom yog 105X160 = 16800 koob / m2
