Malo ogwiritsira ntchito a valve yachitsulo akhoza kugawidwa m'magulu a 8: Chitoliro cha Madzi Otayidwa, chitoliro chopangira madzi, chitoliro chomanga ngalande, chitoliro chokwirira, chitoliro chotulutsa mpweya, chosungira magetsi, chitoliro chaulimi, chitoliro cha mafakitale ndi zina zotero.Chitukuko cha kumanga madzi ndi ngalande chitoliro ndi yachangu, chitukuko cha kumanga madzi ndi ngalande chitoliro ndi bwino, ndi chitukuko cha pansi pansi madzi ngalande chitoliro ndi mpweya kufala chitoliro ndi kutali kumbuyo kwa mayiko akunja.

Komabe, chitukuko cha mavavu kuponyedwa chitsulo ndi zipangizo zina chitoliro ku China ndi m'mbuyo.Malinga ndi chiphunzitso chokhudzana ndi katswiri, chiŵerengero chololera cha chitoliro ndi choyenera pomanga chiyenera kukhala 8: 1, koma malinga ndi ziwerengero mu 1998, chiwerengero cha kupanga chitoliro chachitsulo chopangidwa ndi chitsulo ndi choyenera kumanga ku China ndi za 20: 1 .Kuthekera kwa zida zopangira zitoliro zachitsulo zatsika pang'ono m'zaka zaposachedwa, koma sikuli bwino.Ambiri mwa omwe amapanga zida zopangira zida zachitsulo ndi mabizinesi ang'onoang'ono ndipo ochepa ndi mabizinesi akuluakulu kapena apakatikati.

M'makampani a eyapoti ya Engineering, kusiyana pakati pa zoweta ndi zakunja kumawonekera makamaka muukadaulo wazinthu zoyambira.Choncho, kuti titsitsimutse chitukuko cha mafakitale omangamanga, tiyenera kuyika zoyesayesa zathu pakukweza luso la zigawo zikuluzikulu, kuonjezera luso lazopangapanga zamakono, ndikuwonjezeranso ndi chithandizo cha ndondomeko, kuti tithe kukweza luso lamakono. Zindikirani chitukuko cha makampani.

Kufuna msika kwa zinthu zotayidwa zitsulo vavu makamaka zimachokera mbali ziwiri: choyamba, ntchito ndi chitoliro choponyedwa chitsulo;chachiwiri, kugwiritsa ntchito valavu yachitsulo chachitsulo, kukhazikika, kukana kutopa, kukana kwa dzimbiri sikoyenera kwambiri, komanso kumakhala ndi khalidwe lowala, kugwiritsira ntchito bwino kwambiri komanso ubwino wina wapadera.Kudziko lina, ma valve achitsulo amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mankhwala, kukonza chakudya, m'nyumba ndi kunja kwa madzi ndi ngalande, makina ndi magetsi, ulimi ndi madera ena.Titha kuyembekezera kuti mankhwala opangidwa ndi chitsulo chachitsulo omwe ali ndi khalidwe lapamwamba, ntchito ndi mtengo ali ndi mwayi waukulu wamsika ku China.Ngakhale China italowa mu WTO, ndizinthu zabwino zopikisana pamsika wapadziko lonse lapansi.

Poyankha zofuna zosiyanasiyana za makasitomala, chitukuko cha mayankho mabuku kupereka mwayi kwa makasitomala, komanso ankasewera yopingasa kaphatikizidwe wa sikelo mwayi, kuti zosiyanasiyana mankhwala kugawana chuma chosaoneka, kukulitsa maonekedwe a mabizinesi, mu kuti apange zotchinga kwa omwe alowa m'makampani atsopano, kuchepetsa kupanikizika kwa mpikisano, ndikupeza malo opindulitsa;kudzera m'mitundu yosiyanasiyana, makamaka kuphatikiza kopingasa komanso koyima komanso kupeza, kumatha kuchepetsa omwe akupikisana nawo, kukulitsa gawo la msika, kupititsa patsogolo kulamulira kwa msika, kupanga bizinesiyo kukhala ndi mgwirizano.

Pofuna kulimbikitsa kuthandizira chifukwa cha chitetezo cha chilengedwe, kuonetsetsa kufunikira kwa ndalama zotetezera zachilengedwe, mayiko amatenga njira zosiyanasiyana zofulumira.Mwachitsanzo, Ulaya amalandira ndalama kuchokera ku World Wildlife Fund for Research and development of tetrachloroethene alternatives, ndipo mayiko ena amalipiritsa msonkho wapadera wa chilengedwe pa malonda a tetrachloroethene, omwe amagwiritsidwa ntchito pochiza zinyalala za tetrachloroethene.
