Kenyelletso ea Sehlahisoa

Ho hlahisa li-tubes tsa rona tsa tšepe tse sebetsang ka mokhoa o fapaneng bakeng sa tšebeliso ea indasteri, tse etselitsoeng ho fihlela litlhoko tse boima tsa liindasteri tse ngata. Lihlahisoa tsa rona li etsoa fekthering ea rona ea morao-rao Cangzhou, Profinseng ea Hebei, e leng moetapele oa indasteri ea tšepe ho tloha ka 1993. Ka kakaretso ea sebaka sa lisekoere-mithara tse 350,000 le thepa eohle ea RMB 680 milione, re motlotlo. ho ba le basebetsi ba 680 ba inehetseng le ba nang le litsebo ba netefatsang hore sehlahisoa se seng le se seng seo re se tlisang se finyella litekanyetso tsa boleng bo holimo.

Mokhoa oa rona o ikhethang oa tlhahiso o beha liphaephe tsa rona tsa tšepe ntle le tlhōlisano. E entsoe ka matla le ho tšoarella, liphaephe tsena li khona ho mamella likhatello tse phahameng tsa ka hare le tsa ka ntle, tse etsang hore e be tse loketseng bakeng sa mefuta e mengata ea lisebelisoa. Ho sa tsotellehe hore na u sebetsa kahong, oli le khase, kapa tšimo leha e le efe ea indasteri, liphaephe tsa rona li hahiloe ho sebetsa maemong a thata ka ho fetisisa.

E 'ngoe ea likarolo tse ikhethang tsa mefuta-futa ea ronaphala ea tšepe ea tšepeke khanyetso ea tsona e babatsehang ea ho bola le ho senyeha. Boleng bona ha bo lelefatse bophelo ba liphaephe feela, empa hape bo fokotsa litšenyehelo tsa tlhokomelo, ho fana ka tharollo e ka tšeptjoang bakeng sa litlhoko tsa hau tsa indasteri. Ka boitlamo ba rona ho boqapi le boleng, o ka kholiseha hore lihlahisoa tsa rona li tla fana ka ts'ebetso e babatsehang le ho tšepahala.

Molemo oa Sehlahisoa

1. E 'ngoe ea melemo e ka sehloohong ea liphaephe tsa rona tsa tšepe ke bokhoni ba tsona ba ho mamella likhatello tse phahameng tsa ka hare le tsa ka ntle. Sena se etsa hore e be tse loketseng liindasteri tse kang oli le khase, kaho le tlhahiso.

2. Liphaephe tsena li etselitsoe ho hanela kutu le ho senyeha, ho netefatsa bophelo bo bolelele ba tšebeletso le litšenyehelo tse tlaase tsa tlhokomelo.

3. Ho feto-fetoha ha tsona ho li lumella hore li sebelisoe mefuteng e mengata ea lisebelisoa, ho tloha ho tsamaisa maro ho ea ho tšehetso ea sebopeho.

Khaello ea lihlahisoa

1. Pipe ea tšepee ka ba boima ho feta mekhoa e meng e kang polasetiki kapa lisebelisoa tse kopantsoeng, tse ka bakang mathata nakong ea ho kenya le ho tsamaisa.

2. Le hoja li hanyetsana le ho bola, ha li sireletsehe ka ho feletseng ho senya, haholo-holo libakeng tse thata. Tlhokomelo ea kamehla le liaparo tse sireletsang li ka 'na tsa hlokahala ho lelefatsa bophelo ba bona ba tšebeletso.

Q1: Ke eng e ikhethang ka liphaephe tsee tsa tšepe?

Mokhoa o ikhethang oa tlhahiso o sebelisetsoang ho hlahisa liphaephe tsena tsa tšepe tsa tšepe o eketsa matla a tsona le ho tšoarella haholo. Ho fapana le liphaephe tse tloaelehileng, liphaephe tsena li entsoe hore li khone ho mamella likhatello tse phahameng tsa ka hare le tsa ka ntle, e leng se etsang hore e be tse loketseng bakeng sa maemo a boima a indasteri. Kaho ea eona e tiileng e tiisa bophelo bo bolelele le ho fokotsa tlhoko ea ho nkeloa sebaka khafetsa.

Q2: Na liphaephe tsee ha li na kutu?

ka sebele! E 'ngoe ea likarolo tse ka sehloohong tsa lipeipi tsa rona tsa tšepe ke ho hanyetsa ha tsona ho senya le ho senyeha. Thepa ena e bohlokoa bakeng sa lits'ebetso liindastering tse kang oli le khase, ts'ebetso ea kaho le ea lik'hemik'hale, tseo hangata li pepesetsoang maemo a thata. Ho hanyetsa kutu ho tiisa hore liphaephe li boloka botšepehi ba tsona ka nako e telele, ho fana ka tharollo e tšepahalang bakeng sa merero e fapaneng.

Q3: Liphaephe tsee li etsoa hokae?

Setsi sa rona sa tlhahiso ea lipeipi tsa tšepe se fumaneha Cangzhou City, Profinseng ea Hebei, e nang le feme e tsoetseng pele e koahelang sebaka sa lisekoere-mithara tse 350,000. Khamphani e thehiloe ka 1993 mme e hotse ka potlako ka thepa eohle ea li-yuan tse limilione tse 680 le basebetsi ba 680. Boiphihlelo ba rona bo ruileng le matsete a botekgeniki a re nolofalletsa ho hlahisa liphaephe tsa boleng bo holimo tse fihlelang litlhoko tse fapaneng tsa bareki ba rona.
