Mwamsanga: Kodi chochitika chachibadwa n'chiyani?

Kuyenda kwinakwake kumidzi, kukondwera ndi maluwa, kumvetsera mbalame ndikuimbira nyimbo nyimbo zozizwitsa, mumatha kugwidwa mwamsanga. Koma mwamsanga muyenera kuchenjeza kuti sizili zoopsya, monga momwe mafilimu ena a mtunduwo "amawopsya." Inde, ndithudi, ayenera kupewa, koma nthawi yomweyo musachite mantha. Pali malamulo angapo osasinthasintha, zomwe zingapewe zoterezi.

Kodi mwamsanga? Izi ndizochitika zachilengedwe zokondweretsa , koma palibe mtundu wa nthaka. Chisakanizo chokhala ndi zinthu zabwino kwambiri, dothi ndi madzi (m'malo opanda - mchenga ndi mpweya). Zikuwoneka zolimba, koma zimakhala zosasunthika pakakhala zovuta pamtunda. Zimapangidwa pamene madzi amathira nthaka. Kawirikawiri, chiyambi cha mchenga (kagawe, phiri, nyanja) chimakhala ndi mbewu zodzaza ndi zolimba (pafupifupi 25 mpaka 30 peresenti ya malo pakati pa mbewu yodzaza ndi madzi kapena mpweya). Popeza mchenga wambiri umakhala wosiyana, kupatukana kwawo kumachitika, ndipo voids idzakhala 30 mpaka 70 peresenti ya misa. Njirayi ikufanana ndi nyumba ya makadi pamene malo pakati pa makadi ndi aakulu kwambiri kuposa malo omwe amakhala nawo. Madzi amathandiza kuti pakhale dothi losakanikirana, lomwe silingathe kulemera kwake.

Mchenga wosunthira ukhoza kupanga maimidwe ndi madzi othamanga, akukwera mmwamba (monga momwe zamasinthira). Madzi oyendetsa ndege amatsogolera kupita kumbuyo kukana mphamvu yokoka ndi kuletsa nthaka particles. Mvula yokhutira ikhoza kuoneka yowongoka, koma pang'ono kupanikizika kwapangidwe pamtunda kumayambitsa kunyeketsa. Izi zimapangitsa kuti mchenga upangidwe kukhala wosokoneza ndi kutaya mphamvu yake. Chifukwa cha madzi ammadzi, amadzimadzi amadzimadzi, amadzimadzimadzi, amathimadzi, amathimadzi, amawoneka. Zinthu zomwe zimagwera kumalo otere zimachepetsedwa kufika pamlingo womwe kulemera kwawo kuli kofanana ndi kulemera kwake kosakanikirana (kuchokera mu nthaka ndi madzi). Kudya mchere ndi chinthu chapadera cha zochitika zomwe zikuchitika. Choncho, ngati chivomerezi chikagwedezeka, kuthamanga kwa pore m'madzi osadziwika bwino kumawonjezeka . Nthaka yotentha kwambiri imataya mphamvu, zomwe zimapangitsa kuti nyumba ndi zinthu zina ziwonongeke.

Mchenga umapangidwira kumene akasupe amadziwe, m'malo otsetsereka kapena amchere, pafupi ndi mitsinje, pamphepete mwa nyanja, ngakhale kuti nthawi zambiri sadziwika mosavuta. Ngati mwadzidzidzi mugwera mwa iwo, amatha msanga ndi mofatsa, akuyankhidwa ndi mphindi zingapo. Iwo ndi osakhala a Newtonian madzi, ndiko kuti, mpumulo iwo amaimira olimba (ngati gel), koma pang'ono chabe pa iwo amachititsa kuchepa kwakukulu mu mamasukidwe akayendedwe. M'mapululu, amakhalansopo, koma kawirikawiri, pomwe mchenga amapezeka, mwachitsanzo, kumbali ya maluwa. Koma kuchepetsa kumachepera masentimita angapo, chifukwa kamodzi kamene mpweya umachoka pakati pa mchenga umachotsedwa (ndipo izi zimachitika mwamsanga), amakhalanso osungunuka.
