Chii anoudza muti vakatongoparadzwa

Akagura musango ndokuona tsaru chigutsa, kuziva munhu achaita mira uye teererai Muchikamu shure wemuti. Chii anorangarira? Kuti ndaigona kuudza, kuwana inzwi rake? Erasing kubva cutoff butiro Moss, zviri nyore kuona madenderedzwa vakayambukira ne makatsemuka. muti zvindori angaziva zvakawanda. On vaduku miti, ayo upenyu inaye, nzara kuchitonhora uye kuchipisa, mazuva akaoma. meso ruzivo vanhu vasati kwakaratidza gore negore kunyange kwapera makumi emakore. ichangopfuura, sainzi ichi yakatanga kunonzi dendrochronology.

Pfungwa dendrochronology

Kudzidza muchinjikwa zvikamu hakuna kuoma. The cut muti aongororwe maikorosikopu, mumwe rukoko wepagore akayera mu millimeters. Nezviyero rakaumba rinokosha purogiramu, inoratidza kuchinja zvindori ukobvu. Purogiramu zvichikwira kana pakukora mezvindori vakwanise (akanakira huni makore), kuti girafu ipfupi apo makore akanga akaoma, rinorema. Aongorora matsva Temai muti, uye rangano, zvinokwanisika kuwana rondedzero hwake, zvichiratidza mamiriro okunze pakararama muti, kureva okupedzisira makore nguva yedu. Kuwana musango kutema muti wekare, unofanira kuita zvakafanana basa uye awane purogiramu. On zvichiita kutonga okunze munguva iyo yakakura. Sezvo gore unogona kuenda vanyura nhoroondo gore.

Asi kwete vose nyore. Mumasango European miti yekare regai kurarama makore anopfuura mazana matatu, mazana mana, asi kuti memuouki dzimwe nguva kuita kuti hafu nemireniyumu. Asi pano ndeyokudzidza chekawo hardwood nani zvakaoma. mhete kujeka zvinoratidza zvakavanzika asi ndisingadi. Mune zvimwe zvinobetsera chinzvimbo zvakava masayendisiti ose America. Pane mimwe miti upenyu kwemakore chiuru. Ava vamwe gymnosperms, yellow nemipaini, Douglas omusipiresi. vakatourayiwa imomo YOMUMAKOMO vanoondoroka, izvo akararama mana nehafu chemakore. Panguva Kucherwa pamusoro nzvimbo maIndia yokugara akaona wakatemwa akawanikwa, izvo zvinogona kuita dendrochronological Graphics on rose chemakore.

Mhete negore. Research muRussia

Kwemakore akawanda masayendisiti akadzidza chete huni America. Europe yakanga chena nzvimbo mumunda. Chete pashure pehondo kuRussia, nemasayendisiti kuti Spila yekare. Zvakanga zvakanaka kuti kudzidza kuchamhembe kunzvimbo. Wevhu vari zvakanaka yakakanyiwa uye muchando ivhu akachengetedza zhinji kwazvo muti hunde dzacho. Huge "kukohwa" yematanda masayendisiti unganidzwa Pavaichera yekare Novgorod. Ikoko vakawana zviuru inoverengeka dzinoita siyana, stratified pane mumwe panguva dzakasiyana pakadzika. Rukoko nokuda rukoko necropsied masayendisiti matongo zvinhu: risers machechi, danda flooring, danda matsime. The anowana vakanga pana masere-mita udzamu. Asi sei aigona kusunga zera zvakasiyana zvakawanikwa? Slices omuti hunde akanga agadzirira magazini anopfuura zviuru zvitatu. Mumwe mhando vaifanira kuvaka zvavo dendrochronological akamboona.

Dendrochronologists vakaita chaizvo basa. Havana kungotaura vakamiswa Graphics. Kuisa mashoko purogiramu aifanira kudzidza yose nyaya yeguta rekare, Chronicle, kusarudza negore chii yakavakwa kana kuti yemapuranga maumbirwo.

ReAegean dendrochronological purojekiti

Basa guru reAegean Dendrochronological chirongwa zvawave kwemakore 35. Its chinangwa - kusika paMhedziso dendroshkalu nokuda kuMiddle East uye reAegean nharaunda uye kusanganisira miti kubva pakutanga chemakore BC kusvika ano Exhibits. Work inoitwa nemasayendisiti pana Cornell University, USA. Main results:

• Submitted Mhedziso dendroshkaly mhando dzakadai pomuouki, misidhari, omujunipa, nemipaini. ravo kumwedzi zvinofungidzirwa kuti 750 g BC.
• Akapedza kuvaka imwe zvinoyangarara reAegean dendroshkaly chete zvakarurama 2657-649 makore BC (nokuti omujunipa).
• Uyewo ari yomujunipa muti chekawo akabatsira kuvaka dendroshkalu akayangarara pamusoro nguva 2030-980 BCE. Zvabuda dzakabudiswa muna 2005.
• anozivikanwa nenyaya vaizivikanwa kuti "Roma Makwanza" uye Eva-nyaya.

Nebudiriro American Scientists vachiri vaiona pamakakatanwa, sezvo ndingangokuvara kukanganisa dzimwe nguva, kubvira 100 kusvika 200 makore.

Research muna Finland

Imwe nzvimbo yakakodzera kudzidza kwaiva kuchamhembe Finland. Munzvimbo idzi, mutsetse rinopfuura pamuganhu ekunze. Professor Jan Esper anoti kuti mungarava hunde dzacho ngaunyatsobata mashoko ose emakore. Saka, chiduku bande muti, akavata muchando mudziva, rinotiudza chaizvo. In kuchamhembe Finland pane yakawanda madziva, izvo achengetere mashoko anokosha. Dendrochronologists vanoti kuti vanogona kuzivisa okunze zvakavanzika kwemakore zviuru zviviri zvemakore. Laboratory mushandi achishandisa chaiyo chibooreso ivhu manually muti zvindori zvakabviswa. Vakabva aongororwe maikorosikopu uchishandisa zvigadzirwa kombiyuta. Dendrochronological wakavhomorwa Graphics zvakabatsira kuziva sei zvachinja uye kunyange kana ari munharaunda kuputika kwemakomo kwakaitika.

Climate Change

Maererano mashoko akapiwa, masayendisiti vakakwanisa kumisa kuti munyika dzose chemakore avhareji tembiricha dzaiuya 0.3 inegumi. Izvi kusvikira pakutanga kwezana remakore rechimakumi maviri - the Industrial Revolution wenyika. Development musayenzi uye kwesayenzi mberi kwaita kuti nyika kwakawedzera zvikuru chitsama girinihausi magasi chokwadi. Nguva iyi Dendrochronologists asina kudzidza zvakadzama.

Mumazuva veGladiators Roman kwazara aiva inodziya zvikuru. "Inodziya danho" rinogona kunzi uye neMiddle Ages. Zvino chando Snap, iyo yakaramba ose gore kusvikira 1900. murume ano, nekusiyana, zvino nehanya kwepasi pose. Sezvaunogona kuona, kunyange chiduku bande muti davi kuudza chaizvo. Zvinosuruvarisa veMubatanidzwa inokudza maturo, pamwe zvinhu kusvibisa mhepo uye okunze kunobva, kusvika pamwero wakati, nezvinoitwa nevanhu, asi mashoko ose dendrochronology anogona kupupura chete tembiricha nokufamba.
