Breed - akuyona kuphela Okunengi nofana inja, kodwa futhi enye into

Breed - lokhu mqondo ngempela ezibanzi. Breed kuboniswe wonke okuqondene kezinye, engqondweni, njengoba ophilayo akuvumi ukuba aphile.

Asho ukuthini lokhu

Breed - igama elibi eziningi eziphilayo futhi eziphilayo-non-ophilayo. Bungabonakala:

1. Izilwane, ezingafani endaweni noma imphahla. Ngokwesibonelo, zohlobo izilwane ezingaba kuphela ahlala enyakatho noma eningizimu. It lusobala womuntu (inja izinhlobo, amakati, njll). Breed yizo zonke izilwane abahlala emaqeleni ihlathi, ikhaya emakhaya.
2. Izitshalo. Ngokuvamile, izihlahla awabonakali ezifana AmaConifers.
3. Minerals, izinto yezimayini.
4. Ngezinye izikhathi igama elithi "idwala" libhekisela kubantu kobulili babo, imvelaphi.

Breed kungenzeka idluliselwe impahla esithambile noma esiqinile, ezifana izinkuni.

izinkuni

rock Hard - iqoqo izinhlobo ezahlukene izinto, okuyinto kunqunywa izindlela ezehlukene. Kuvame kakhulu esetshenziswa ukukhomba nobulukhuni ukhuni indlela Brinell. Luhilela nesilinganiso ka indentations eHoreshi ukujula. Ngenxa yalesi umthwalo icindezelwa ibe ibhola metal. Labe ekhishwe walinganisa we trace ezisele ubulukhuni amayunithi (HB) ukujula.

Ngezinye izikhathi nobulukhuni kukalwa the Rockwell esikalini. Isimiso ukumeda elifana wangaphambilini, kodwa amayunithi angakahleleki kuleli cala, abanye - HRC noma HRA, HRB.

Imiphumela yocwaningo division ihlanganiswe izihlahla ubulukhuni. Okokuqala Jatoba nge nobulukhuni 7 HB. Ibe isilandelwa Sucupira, ogama ubulukhuni kuyinto 5.6 HB.

Zonke izihlahla nge nobulukhuni esingaphansi 4 HB libhekisela esithambile.

rocks okuqinile

rock Hard - umzimba okuqinile odabuka yemvelo, zihlukaniswe ngezigaba ezintathu eziyinhloko: sedimentary, igneous futhi metamorfoznye.

Indaba obujwayelekile egwadle Lokudabuka magmatic. It is kabanzi ekwakheni.

I uqweqwe phezulu isebangeni rocks sedimentary. Ziyakwazi umphumela umsebenzi eziphilayo noma ukoniwa yezinye izinhlobo. rock sedimentary - a sub-izinhlobo ezimbalwa, ezihlanganisa clastic, zamakhemikhali izinhlobo eziphilayo.

Metamorphic ngokuvamile uvezwa slate, zemabula asebenza ngebhethri. Lezi izinto akhiwa ngaphansi isenzo lokushisa eliphezulu kanye umfutho ophakeme.

izilwane

Nokuzalanisa izilwane - yilona qembu eziningi abamele zohlobo olulodwa, elinomlando ukuthuthukiswa. Ngokuvamile zohlobo uye izakhiwo ezithile njengefa futhi esingokwemvelo ezakhini zofuzo. Ngaphezu kwalokho, kubalulekile ukuthi abazali kanye nenzalo babe izici ezifanayo, Imizimba imibala. Ngu ukweqa izinhlobo ezahlukene noma nzalo etholwe metises.

Ukuze uhlobo olusha ukuchitha umsebenzi omkhulu amashumi eminyaka. Umphumela ezizukulwane eziningana izilwane, okuyinto yembula nezimpawu ezifanayo zangaphandle, izici zofuzo nikubeke ezinhliziyweni zenu.

Uma abalimi izuzwe elamukelekile (kwezizukulwane ezimbalwa ezifanayo, izici esingashintshi), ubizwa ngokuthi namazinga zohlobo. Kusukela izilwane ezinjalo siyinzalo purebred e isamba yokuthi kungenzeka ukuba alondoloze ubumsulwa zohlobo. Ngemva kokufinyelela oyifunayo umphumela zohlobo irejista ngokuyibophela yona ezweni elithile.

izitshalo

Futhi ukuzalela sekuvele uhlobo olusha zezihlahla. Basuke etholwe ukweqa izinhlobo ezahlukene, zama-pine, thuja, umjunipha. Ngenxa yalokho, abalimi bengathola izitshalo nemithi ukuthi babe izakhiwo engavamile. Ngokwesibonelo, uphayini yemifino, AmaConifers, uyakwazi withstanding yesithwathwa ezinzima, uphayini Izigaxa ngemibala engavamile, izinaliti.

Yisiphi zohlobo - umphumela umsebenzi kwenziwe isikhathi eside. Ungalokothi engqondweni, yena wadala ngokwemvelo noma indoda.
