Ratio to the volume of the mass of ntoo - qhov no yog qhov ceev ntawm tsob ntoo yog xam , Txawm hom tsiaj twg peb tham txog. Kg\m3 - qhov no yog qhov tus yam ntxwv no qhia thiab qhia. Hauv txhua tus neeg yug tsiaj, qhov ntom ntom yog nyob ntawm cov khoom uas txhais lub cell. Tsis tas li ntawd, qhov loj ntawm cov khoom ntoo ntawm ib chav tsev ntim tau dhau los ua qhov tseem ceeb tshaj plaws. Nws yog cov cuab yeej no uas txiav txim siab qhov tseeb tias txhua tus tsiaj muaj nws qhov ntom ntom.
Koj xav paub dab tsi ntxiv txog qhov ntom ntom?
Thaum xam qhov ntom rau ib hom tsiaj, lawv hais txog qhov nruab nrab lossis tus yam ntxwv. Nyob rau hauv cov ntaub ntawv ntawm ib tug conditional, lawv tham txog qhov kev sib raug zoo rau lub ntim ntawm lub loj, tab sis lub ntim ntawm cell kab noj hniav yog tsis coj mus rau hauv tus account. Thiab ntoo nws tus kheej raug ntsuas nyob rau hauv lub xeev qhuav tag.
Rau txhua hom ntoo, cov khoom tseem ceeb muaj kwv yees li ntawm tib yam. Thaum xam qhov ceev ntawm tsob ntoo, , qhov no yuav tsum nco ntsoov tas li. Tias yog vim li cas nyob rau hauv tag nrho cov breeds no conditional yam ntxwv muaj kwv yees li tus nqi tib yam. Qhov no yog tus naj npawb 1, 56 gsm2. NtawmCov av noo ntawm 12 feem pua, txhua qhov ntsuas ntawm lub cev thiab cov khoom siv kho tshuab raug txiav txim siab. Qhov ntom ntawm ntoo yog cuam tshuam nrog lub zog. Cov yam ntxwv no kuj tseem nyob ntawm cov av noo heev. Muaj cov rooj tshwj xeeb txhawm rau kawm cov yam ntxwv ntawm ib hom tsiaj.
Dab tsi txog qhov nruab nrab ntom ntom?
Ntoo porosity thiab av noo yog cov cim tseem ceeb uas txiav txim siab qhov ntsuas no. Feem ntau, tus nqi yog muab nyob rau hauv 15 feem pua ntawm cov av noo.
Vim li cas thiaj tseem ceeb kom paub tus yam ntxwv no?
Hauv kev xyaum, qhov ntom ntawm tsob ntoo tseem ceeb heev. Piv txwv li, ntoo yuav hnyav dua thiab nyuaj, uas qhov ntsuas no siab dua. Qhov no txhais tau tias cov khoom siv yuav nyuaj dua rau kev ua haujlwm. Antiseptic ntoo uas muaj qhov ntom ntom ntom kuj tseem ua tiav ntau dua li lwm cov kev xaiv.
Qhov kev ntsuas no yog lub hauv paus rau kev faib tawm, raws li cov tsiaj uas twb muaj lawm tuaj yeem muab faib ua peb pawg. Piv txwv li, cov ntoo uas muaj qhov ntom ntom. Ntawm cov conifers, pawg no suav nrog txhua hom fir thiab spruce, ntoo thuv, txhua hom cedar, thiab ntau hom juniper. Yog hais tias peb tham txog hardwoods, ces Amur velvet, Manchurian, grey thiab dawb walnut, sowing chestnut, dub thiab dawb alder, aspen, txhua hom willow, linden thiab poplar yog tsim nyog hais.
Yuav ua li cas lwm yam ntoo muaj?
Daim duab nruab nrab ntawm qhov kev taw qhia no yog cov lej ntawm 560 txog 750. Ntawm cov conifers, yew thiab larch yog qhov nosiab. Tab sis muaj ntau tus neeg sawv cev ntawm hardwoods ntawm no. Piv txwv li, Manchurian thiab ntau tshauv, kua, persimmon, roob tshauv, dav hlau ntoo, walnut, hazel, maple, elm, elm, Mongolian, marsh, oriental thiab lub caij ntuj sov ntoo qhib, pear, elm, European thiab oriental beech, dub thiab daj, fluffy, warty birch. Cov no yog hom uas yuav luag tib qhov ntom ntawm ntoo. Lub rooj yuav pab koj nkag siab txog cov yam ntxwv ntawm qhov ntsuas no, tsuas yog nrhiav cov khoom tsim nyog.
Tus lej ntawm 750 thiab siab dua tsis yog ntau, tab sis koj tseem tuaj yeem pom cov ntoo zoo li no. Piv txwv li, pistachio thiab boxwood. Los yog tub sab. Qhov ntom ntawm hom ntoo hauv pawg no yog qhov xav tsis thoob, tab sis feem ntau ntawm cov nroj tsuag no tau xyaum tsis pom hauv peb lub tebchaws.

Tsis siv neeg tshuab dhos yog cov cuab yeej siv niaj hnub siv feem ntau hauv kev tsim khoom ntau. Muaj ntau ntau yam ntawm cov tshuab xws li. Ib hom nrov tshaj plaws yog longitudinal tig lathes
Dab tsi yog qhov project. Txhais ntawm qhov project, nws cov yam ntxwv thiab cov yam ntxwv
Lo lus "project" (projectus) yog txhais los ntawm Latin tias "zoo, txav mus tom ntej, protruding." Thiab yog tias koj rov tsim dua lub tswv yim ntawm "txoj haujlwm txhais" hauv Oxford lexicon, koj tau txais: "kev npaj pib ua lag luam zoo, lub tuam txhab tsim tus kheej, lossis kev sib koom ua haujlwm txhawm rau ua tiav cov hom phiaj tshwj xeeb"
