Kev sib raug zoo ntawm lub thawv ntim khoom thiab cov khoom siv ntuj tsim

Kev sib raug zoo ntawm lub thawv ntim khoom thiab cov khoom siv ntuj tsim
Cov khoom siv ntuj tsim yog hais txog txhua yam khoom siv ntuj tsim uas muaj nyob hauv xwm thiab tib neeg siv tau. Nws suav nrog cov khoom siv hauv av, cov khoom siv raw minerals, cov khoom siv zog, cov khoom siv biological, cov khoom siv dej thiab lwm yam khoom siv ntuj tsim, tab sis tsis suav nrog cov khoom siv raw uas tib neeg tsim. Lawv yog cov khoom siv rau tib neeg kom tau txais kev ua neej nyob thiab yog lub hauv paus ntuj tsim ntawm kev tsim khoom hauv zej zog.Lub thawv xa ntawv

Cov peev txheej ntuj tsim muaj kev sib raug zoo heev nrog kev txhim kho kev ntim khoom thiab yog cov khoom siv tseem ceeb ntawm kev tsim khoom lag luam ntim khoom.
Cov peev txheej ntuj tsim, tshwj xeeb tshaj yog cov khoom siv raw minerals thiab cov peev txheej zog, muaj qhov tseem ceeb dua rau kev txhim kho kev lag luam ntim khoom. Lub zog tsis yog tsuas yog lub hauv paus ntawm lub zog ntawm kev lag luam ntim khoom xwb, qee lub zog (roj, roj av, thee, thiab lwm yam) tsis yog tsuas yog cov khoom siv tseem ceeb ntawm kev lag luam tshuaj lom neeg xwb, tab sis kuj yog cov khoom siv raw ntawm kev tsim cov khoom ntim khoom; Cov peev txheej raw minerals yog cov khoom siv tseem ceeb ntawm ntau hom hlau raw khoom thiab cov khoom siv tsis yog hlau raw khoom uas kev lag luam ntim khoom xav tau.Lub thawv tswm ciab

Cov tuam txhab tsim khoom ntim khoom siv cov kev ua tiav niaj hnub ntawm kev tshawb fawb thiab kev siv tshuab los siv tag nrho cov peev txheej ntuj, tsis yog tsuas yog xyuas kom meej tias cov khoom zoo, txo cov nqi muaj kev cuam tshuam ncaj qha, tab sis kuj tseem tiv thaiv kev ua qias tuaj ib puag ncig thiab tswj kev sib npaug ntawm ecological muaj lub luag haujlwm tseem ceeb.Lub thawv hniav nyiaj hniav kub
Qhov kev sib raug zoo ntawm kev ntim khoom thiab kev tiv thaiv ib puag ncig thiab kev sib npaug ntawm ecological feem ntau yog pom tseeb hauv ob qho: qhov cuam tshuam ntawm kev lag luam ntim khoom rau ib puag ncig thiab qhov cuam tshuam ntawm cov khib nyiab ntim khoom rau ib puag ncig.Lub thawv plaub hau
Kev lag luam ntim khoom muaj xws li kev ua ntawv, yas, iav, hlau smelting thiab kev ua qee yam khoom siv pabcuam thiab lwm yam kev lag luam tso pa tawm ntawm cov pa roj pov tseg, dej pov tseg thiab cov khib nyiab pov tseg, uas muaj ntau yam inorganic thiab organic matter. Yog tias cov khib nyiab tsis kho muaj cov tshuaj lom thiab cov kab mob me me, cov cai lij choj hauv xeev yuav tsum tau ua raws li nruj me ntsis, cov teeb meem kev tiv thaiv ib puag ncig yuav tsum tau daws kom zoo, thiab cov txiaj ntsig kev lag luam, kev sib raug zoo thiab kev nyab xeeb yuav tsum tau sib npaug.Lub thawv plaub muag
Nrog rau kev txhim kho ntawm kev lag luam thiab kev txhim kho tas mus li ntawm cov neeg lub neej, kev lag luam ntim khoom muab ntau dua thiab ntau dua cov khoom ntim, thiab cov khib nyiab tom qab ntim kuj nce ntxiv, ua rau muaj kev phom sij ntawm cov khib nyiab. Kev pov tseg cov khib nyiab yog qhov teeb meem thorny. Yog tias pov tseg rau hauv qhov chaw pov tseg, cov tshuaj lom neeg hauv nws tuaj yeem ua rau cov av thiab dej hauv av qias neeg. Yas nyuaj rau rhuav tshem, thiab thaum ntxuav los ntawm nag rau hauv cov dej, pas dej thiab dej hiav txwv, nws tuaj yeem ua rau qee cov tsiaj hauv dej puas tsuaj. Yog tias kho los ntawm kev hlawv, qee cov tshuaj lom neeg tso tawm rau hauv huab cua yuav tsim "kev phom sij rau pej xeem thib ob", xws li cov pa roj acid, nag acid, ua rau cov nroj tsuag hauv av thiab cov tsiaj hauv dej puas tsuaj, cuam tshuam rau qhov zoo ntawm cov qoob loo thiab cov khoom hauv dej; Qee cov pa roj lom, los ntawm kev ua pa ntawm tib neeg thiab kev sib cuag ntawm daim tawv nqaij, ua rau muaj kev pheej hmoo ntawm kab mob, mob qog noj ntshav. Yog li ntawd, kev kawm thiab kev siv cov ntim khoom tsis muaj kuab paug yog ib qho tseem ceeb los tsim cov ntim khoom niaj hnub. Saib lub thawv
