Yintoni ebonisa ukuba ubunzima ezithile yehlathi?

ubunzima oluthile iinkuni iyahlozinga. Eli xabiso kuxhomekeke uhlobo ukufuma. Ingxinano kungohluka nkqu uhlobo olufanayo beenkuni. Ngenxa yokuba abafundi abagqibayo kwiitheyibhile data ihlanganiselwe kuphela. Ukuziqhelisa, iseha iinkuni imiyinge mninzi zahlukile kwezo inikwe kule ncwadi amaxabiso itafile kunye nokuhlela loo akujongwa asilotyala.

iinkuni Table mninzi

Okubalulekileyo! Le theyibhile iqulethe iinkuni neziphawuli ukufuma data esekelwe-12%. Umzekelo, umlinganiselo iinkuni pine 520 kg / m ^3.

Kulo elo nani kuxhomekeke

Ukuxinana bomthi na uhlobo uzimisele. Ngokunjalo, ibalwe avareji ixabiso ubunzima ezithile beenkuni aqhelekileyo ezo zifunyenwe ngenxa zophando ezininzi ezisebenzayo. Ngexesha uthotho umfuniselo uhlobo omnye zingafumaneka ezahlukeneyo isakhiwo yokusebenza mninzi. Enyanisweni, xa itafile ngentla, yaqokelelwa data kwi kwanokuxinana kweentlobo zemithi eqokelelweyo evela kwimithombo eyahlukeneyo, ebonisa ukuba Ukwahluka yokusebenza ngokwenene wayesisalamane ubunzima ezithile kweenkuni.

iinkuni mninzi Groups

Oku ukubala ngokubanzi ubunzima ngomthi iintlobo ezahlukeneyo kunye isiqulatho sokufuma ngentla-12%. It ngumlinganiselo olumisiweyo, njengoko apho amaplanga wahlulwe ezintathu Group mninzi:

1. ingxinano Low (ukuya kwi 545 kg / m ^3). Olu didi lubandakanya: nespruce, pine, msipres, nomsedare, konwele, poplar, Linden, willow, Aspen, alder (amhlophe namnyama), nezompleyini elithozamisayo, Anut (white, ongwevu, isiManchu), Amur ukhokho.
2. Sredneplotnye (555-745 kg / m ³⁾ Amawa: larch, yew, ezinde (povisloj ezintofontofo, omnyama, omthubi), beech (oriental, yaseYurophu), Elm, pere, um-oki, maple, uHazel, Anut, nemikhiwane, ash entabeni, ePersimmon, apile, ash (eziqhelekileyo, sesiManchu).
3. ezixineneyo (ngasentla 755 kg / m ^3), ziphakathi leyo: nemingampunzi, ezinde intsimbi, hornbeam, um-oki, nezompleyini, imithi intsimbi, boxwood, zepistasi, ostrya.

Lo mzobo ngezantsi na umthi umzobo rock bobuso. Imilinganiselo singeniswe okuza.

Njengoko lexinene zeengxondorha edibene LINGATSHA iinkuni

Ixabiso calorific iinkuni (ixabiso amandla ukufudumeza) limiselwa ukusuka index lokuqala - iinkuni gravity ethile. Oku kungenxa yokuba nolwalamano ngqo: oluphezulu lexinene lwesakhiwo engxondorheni, i iphezulu ipesenti mba ezinokutsha eziqulethwe kunye ngcono fuel komtshiso oko.

A mninzi ngenkuthalo ukuze asetyenziswe ekwakheni, ngokukhetha into ekwakheni izindlu, inkqubo truss kophahla, ayile ifenitshala, ukuthenga zibe kukudla imveliso.

Yenza ngaphandle iimveliso iinkuni processing engenakwenzeka. Yalahla ngemithi, abantu abakwazi ayisekho ngokupheleleyo. Ngenxa yokuba izifundo olwenziwe emithi, ibaluleke kakhulu, kuba ebulela iinjineli ukulawula ngokuyila kumakhaya eziluqilima, ukuvelisa ifenitshala eyomeleleyo oluthembekileyo, ukuthenga izinto ekrwada ezikumgangatho ophezulu ngenxa ukufudumeza kwamashishini.
