Unogona kunge uchiziva girazi, asi unoziva kwakabva girazi?Girazi harina kutanga munguva dzemazuva ano, asi muEgypt makore 4000 apfuura.
Mumazuva iwayo, vanhu vaisarudza mamineral chaiwo vobva vanyungudusa patembiricha yakakwira voakanda muchimiro, zvichibva zvaita kuti pave negirazi rekutanga.Zvisinei, girazi rakanga risina kujeka sezvazviri nhasi, uye yaingova gare gare, sezvo teknolojia yakavandudzwa, kuti girazi remazuva ano rakatora chimiro.
Vamwe vanochera matongo vakaona girazi kubva kuzviuru zvemakore zvakapfuura, uye magadzirirwo acho akanyatsotsanangurwa.Ikoku kwakamutsa fariro yavanhu vakawanda muidi rokuti girazi rakapukunyuka denga kwezviuru zvamakore pasina kushatisa muzvarirwo.Saka kubva pakuona kwesainzi, inguva yakareba sei yatingakanda bhodhoro regirazi musango uye ivepo mune zvakasikwa?
Pane dzidziso yokuti inogona kuvapo kwemamiriyoni emakore, iyo isiri fungidziro asi ine chokwadi chakati kwairi.
Girazi rakagadzikana
Zvizhinji zvemidziyo inoshandiswa kuchengeta makemikari, somuenzaniso, yakagadzirwa negirazi.Mamwe acho anogona kukonzera tsaona kana akadururwa, uye girazi, kunyange rakaoma, harina kusimba uye rinogona kutyoka kana rakadonhera pasi.
Kana makemikari aya ane ngozi, sei kushandisa girazi semudziyo?Hazvingave zviri nani here kushandisa simbi isina simbi, isingaite kudonha uye kuita ngura?
Izvi zvinodaro nekuti girazi rakanyatsogadzikana, zvese mumuviri nemakemikari, uye ndiro rakanakisa pane zvese zvinhu.Panyama, girazi hariputsi pakupisa kwepamusoro kana kwakaderera.Zvingave mukupisa kwezhizha kana mukutonhora kwechando, girazi rinoramba rakagadzikana mumuviri.
Panyaya yekugadzikana kwemakemikari, girazi zvakare rakagadzikana zvakanyanya kupfuura simbi dzakadai sesimbi isina tsvina.Mamwe maasidhi uye alkaline zvinhu hazvigone kukanganisa girazi kana yaiswa mugirazi.Zvisinei, kudai simbi isina tsvina yaizoshandiswa panzvimbo pezvo, yaisazotora nguva refu kuti ngarava yacho isati yanyungudutswa.Kunyange zvazvo girazi richinzi harinetse kuputsika, harina ngozi zvakare kana rakachengetwa zvakanaka.
Kurasa girazi mune zvakasikwa
Nekuda kwekuti girazi rakadzikama, zvinonetsa kukanda marara egirazi muzvisikwa kuti zvidzikise zvagara.Isu tagara tichinzwa kare kuti mapurasitiki akaoma kusvibisa zvisikwa, kunyange mushure memakumi emakore kana kunyange mazana emakore.
Asi nguva ino haisi chinhu kana ichienzaniswa negirazi.
Zvinoenderana neazvino data rekuyedza, zvinogona kutora mamirioni emakore kuti girazi ridzikise zvachose.
Kune huwandu hukuru hwema microorganisms mune zvakasikwa, uye ma microorganisms akasiyana ane maitiro akasiyana uye zvinodiwa.Zvisinei, ma microorganisms haadye pagirazi, saka hapana chikonzero chekufunga nezvekugona kwegirazi kuderedzwa nehutachiona.
Imwe nzira iyo zvisikwa zvinosvibisa zvinhu zvinonzi oxidation, sekuti kana chidimbu chepurasitiki chena chikandwa muzvisikwa, nekufamba kwenguva purasitiki inozoita oxidise kune yero ruvara.Plastiki inozobva yaita brittle uye kutsemuka kusvika yaputsika pasi, ndiro simba rezvisikwa oxidation.
Kunyangwe simbi inoita seyakaomarara haina kusimba pamberi peiyo oxidation, asi girazi rinoshingirira kune oxidation.Okisijeni haigone kuita chero chinhu kwairi kunyangwe ikaiswa mumasikirwo, ndicho chikonzero nei zvisingabviri kushatisa girazi munguva pfupi.
Inonakidza magirazi emahombekombe
Nei mapoka ezvemhoteredzo asingarambi kuti magirazi akakandirwa muzvisikwa nepo risingagoni kuderedzwa?Nemhaka yokuti chinhu chacho hachina kukuvadza zvakanyanya kune zvakatipoteredza, chinoramba chiri chimwe chete kana chakakandwa mumvura uye chinoramba chakadaro kana chakakandwa panyika, uye hachizoora kwezviuru zvemakore.
Dzimwe nzvimbo dzinozodzokorodza girazi rakashandiswa, semuenzaniso, mabhodhoro egirazi anozozadzwa nezvinwiwa kana kunyungudutswa kukanda chimwe chinhu.Asi girazi rekudzokorodza zvakare rinodhura zvakanyanya uye kare bhodhoro regirazi raifanira kucheneswa risati razadzwa uye kushandiswa zvakare.
Gare gare, sezvo teknolojia yakavandudzwa, zvakava pachena kuti zvakanga zvakachipa kugadzira bhodhoro regirazi idzva pane kudzorera rimwe.Kudzokororwa kwemabhodhoro egirazi kwakasiiwa uye mabhodhoro asina basa akasiiwa akarara pamahombekombe.
Sezvo mafungu anogeza pamusoro pavo, mabhodhoro egirazi anopindirana uye anoparadzira zvidimbu pamhenderekedzo yegungwa, nokudaro achigadzira gungwa regirazi.Zvingaita sekuti zvinokwenya maoko netsoka dzevanhu zviri nyore, asi chokwadi mahombekombe egungwa akawanda haachakwanisi kukuvadza vanhu.
Izvi zvinodaro nekuti sezvo matombo anokwesha pagirazi mipendero inovawo zvishoma nezvishoma uye inorasikirwa nekucheka kwayo.Vamwe vanhu vane pfungwa dzebhizimisi vari kushandisawo mahombekombe egungwa akadai senzvimbo dzinokwezva vashanyi kuti vawane mari.
Girazi sechinhu chemangwana
Patova nemarara akawanda egirazi akaunganidzwa mune zvakasikwa, uye sezvo zvigadzirwa zvegirazi zvinoramba zvichigadzirwa, huwandu hwegirazi inorasa iyi huchakura zvakanyanya mune ramangwana.
Mamwe masayendisiti akataura kuti mune ramangwana, kana ore inoshandiswa kugadzira girazi iri shoma, girazi rinorasa iri ringangove mudziyo.
Rakandwazve muchoto, girazi remarara rinogona kukandwazve mumidziyo yegirazi.Iko hakuna kudikanwa kwenzvimbo chaiyo yekuchengetera iyi ramangwana resource, pamhene kana mudura, sezvo girazi rakagadzikana zvakanyanya.
Girazi risingatsivike
Girazi rakaita basa rinokosha mukukura kwevanhu.Munguva dzakapfuura vaIjipita vaigadzira girazi rekushongedza, asi gare gare pagirazi raigona kugadzirwa mumhando dzakasiyana dzemidziyo.Girazi rakava chinhu chakajairika chero usina kuripwanya.
Gare gare, nzira dzakakosha dzakashandiswa kuita kuti girazi rive pachena, izvo zvakapa preconditions yekugadzirwa kwetelescope.
Kugadzirwa kweteresikopu kwakapinza zera rokufambisa, uye kushandiswa kwegirazi mumateresikopu enyeredzi kwakapa rudzi rwomunhu nzwisiso yakakwana yechisiko chapose pose.Zvakanaka kutaura kuti tekinoroji yedu ingadai isina kusvika pakakwirira yainayo pasina girazi.
Mune ramangwana, girazi rinoramba richiita basa rakakosha uye rive chigadzirwa chisingachinji.
Girazi rakakosha rinoshandiswa muzvinhu zvakaita semalaser, pamwe nemidziyo yendege.Kunyangwe nharembozha dzatinoshandisa dzakasiya mapurasitiki asingadziviriri uye achinja kuCorning girazi kuitira kuti tiwane kuratidzwa kuri nani.Mushure mekuverenga ongororo idzi, iwe unongoerekana wanzwa kuti girazi risingaonekwe rakakwirira uye rine simba?
