Yuav ua li cas uproot lub hauv paus: cov kev cai

Tag nrho cov paub txoj kev tu lub feem ntawm cov ntoo residues yuav tau muab faib mus rau hauv cov neeg kho tshuab thiab tshuaj. Daim ntawv thov ntawm Science News for KIDS - nws yog ib qho hauj lwm yooj yim, tab sis nws yuav siv sij hawm ib tug ntev lub sij hawm ntawm lub sij hawm. Npaj decompose mus rau hauv cov hmoov av hauv lub hauv paus ntoo, los yog ua rau nws cov.

Tshuaj kev rau qhov kev tshem tawm ntawm stumps:

1. Los ntawm kev siv nitrate. Nyob rau hauv hauv paus ntoo, ob saum toj no thiab laterally (sab tob) drilled qhov sib txawv ntawm cov dav thiab tob. Nyob rau hauv lub caij nplooj zeeg, thaum sau nyob ib ncig ntawm nws tshem tawm thiab ntxuav txhua yam, pw qhov brim nitrate. Ib txhia qhia los qhwv lub hauv paus tom qab cov zaj duab xis los mus tiv thaiv cov dej nyob rau hauv lub formulation, thaum lwm tus neeg pom zoo kom siv cov dej. Uas lub tswv yim yuav koj tsis mloog, lawv lub ntsiab lus yog tib yam: cov tshuaj yuav tau tseg ncuav raws li lawv tsau ntoo. Thaum hauv paus noo nrog saltpeter, thaum nws nkag mus rau thiab oxygen. Tom ntej no, qhuav kiag li soaked hauv paus. Qhuav lub ntsis, peb cog ib tsob ntoo hauv paus ntoo nyob rau hluav taws. Nitrate nyob rau hauv ua ke nrog nrog rau oxygen yuav ua ntev li kev noj nyiaj txiag tsis yog tsuas yog lub hauv av ib feem ntawm tsob ntoo, tab sis cov keeb kwm ntawm qhov tob. Kev tshem tawm ntawm stumps nyob rau hauv no yav tas yog tsis tau, yog hais tias tus peat av. Qhov hluav taws kub lawv ua tau tsis tau, ces nws yog tsis yooj yim sua tua.
2. Nrog rau kev siv ntawm ntsev. Nplua mias rau nphoo ntxhib ntsev hauv paus. Maj mam, nyob rau hauv tus ntawm ntoo pellets yuav pib crumble. Tab sis siv tus qauv no, koj muaj peev xwm ua rau lub zoo tshaj ntawm cov uas lwm tus av. Yog li ntawd nws yog siv, clearing lub site rau kev tsim kho. Tshuaj kev tsis lug siv vim hais tias nws yog ib tug ntev txoj kev.

txhua yam kev

Cov kev koom nrog hauv daim ntawv thov ntawm ib tug lub cev ua phem thiab ntawm tej yam yooj yim cov cuab yeej. Ua ntej koj noj txoj hauj lwm no, nws yog tsim nyog yuav xa cov ntaus ntawv tsob ntoo hauv paus systems. Nws yog ib ob hom: fibrous thiab kav. Qws - pas nrig hauv paus mus sib sib zog nqus, fibrous - uas nws kim heev hauv paus system. Yog hais tias koj kawm tag nrho cov paub txoj kev yuav ua li cas uproot lub hauv paus, koj muaj peev xwm tsim ib tug technology tom qhov kev tshwm sim. Yog li ntawd cia tus pib. Ntawm cov cuab yeej uas peb yuav tsum tau duav, crowbar, kaw los yog hacksaw, ib tug taus, ib tug winch. Nrog tus nqaj hlau nto txhais nrhiav cov hauv paus hniav. Duav tshem tawm hauv av los ntawm nyob rau hauv lawv thiab ib hacksaw rau pom. Yog hais tias ib tug me me ntoo hauv paus ntoo, ces tom qab nws kaw nrog ib tug tes, koj yuav tau sim kom muab tso rau tsob ntoo rau ntawm nws sab thiab tsuav tawm los yog pom tawm tawm hauv sib sib zog nqus cov hauv paus hniav.

Yuav ua li cas uproot lub hauv paus ntawm ib tsob ntoo, yog hais tias nws yog loj?

Medium-qhov loj qhov keeb kwm yog muab tshem tawm, raws li tau zoo raws li me me, tab sis, nrog rau kev siv ntawm seem raws li ib tug lifting mechanism thiab lub hwj chim ntawm ob los yog peb tug neeg laus caug. Raws li ib qho kev xaiv - mus khawb tawm ib lub qhov nyob rau hauv ib tsob ntoo, thiab ntau ntau dej siab ntxuav tawm cov hauv paus hniav.

Yog hais tias hnyav machinery yuav tsis ua hauj lwm, ntiav cov tub txawg. Lawv twb muaj lawm pab kiag li lawm yuav tsiv mus nyob ib ob peb ntawm cov poj niam, li ntawd, tsis tas yuav tso ntau qhov chaw. Cov chaw no yog shattering cov ntoo residues rau hauv daim tsis tsuas yog los ntawm saum toj no tab sis kuj mus rau ib tug tob ntawm 60 cm. Raws li koj tau pom, leej twg yuav nrhiav tau cov lus teb rau lo lus nug ntawm yuav ua li cas uproot lub hauv paus, nyob rau hauv nws tus kheej kev txiav txim.
