Kuti uwedzere mutengo wekugadzirwa kwemakemikari uye kuchengetedza yakakwira mhando yechigadzirwa, unofanirwa kutora anomiririra maitiro emvura yekuongorora murabhoritari nguva nenguva.Sampling (inozivikanwawo sespot sampling, field sampling, kana rational sampling) inobatsira kuona maitiro ekuita uye kuona kuti chigadzirwa chinogadzirwa chinosangana nemukati kana mutengi zvinoenderana nezvinodiwa.
Mitemo inokosha yekuenzanisa
1: Sample inofanira kumiririra mamiriro ekuita, uye probe inofanira kushandiswa kuburitsa sampu kubva pakati pepombi yekugadzira kudzivirira shanduko yechikamu panguva yekufambisa sampuli.
2: Muenzaniso unofanirwa kunge uri munguva.Kupfupisa nguva yekufambisa kubva kunzvimbo yekuchera kuenda kurabhoritari kunobatsira kuve nechokwadi chekuti mamiriro ekuita anonyatso kuratidzwa.
3: Muenzaniso unofanirwa kuve wakachena.Dzivisa chubhu yakafa nzvimbo kumusoro kwechigadziko chemuenzaniso uye bvumira kucheneswa kwakakwana uye kutsvaira kwesampling system kuderedza mukana wekusvibiswa.
Funga nezvemaitiro emvura iyo gasi inonyungudika.Kana tembiricha ichiwedzera uye kudzvinyirira kuderera, gasi rakanyungudika rinogona kufashaira kunze kwemuenzaniso.Kana kuti funga nezvesampu yegasi ine tembiricha yakaderera uye yakanyanya kudzvanywa, izvo zvinogona kuita kuti mvura ionde uye iparadzanise kubva kumuenzaniso.Muchiitiko chega chega, kuumbwa kwemuenzaniso kunoshanduka zvakanyanya, saka haichakwanisi kumiririra mamiriro ekugadzirisa.
Nekuda kwezvikonzero zviri pamusoro, zvakakosha kushandisamabhodhoro emuenzanisokuunganidza gasi kana liquefied gasi kuitira kuchengetedza chikamu chakanaka uye kuchengetedza kumiririra kwemuenzaniso.Kana iyo gasi ine muchetura, silinda inoshandawo mukudzivirira samuenzaniso tekinoroji uye nharaunda kubva kuhutsi kana kupera simba.
