Ukukhula kwamangqamuzana akuncikile nje ekwakhiweni kwemisoco eningi, kodwa futhi kudinga ukuba phakathi kwenani le-pH elifanele ukuze kukhule okujwayelekile kanye nokuzalana. Ngakho-ke, ngaphambi kokusebenzisa i-cell factory yesiko lamaseli amakhulu, inani le-pH yendawo kufanele likalwe futhi lilungiswe kuqala.
Ivelu ye-pH ibhekisela esilinganisweni senani lonke lama-ion e-hydrogen. esixazululweni senani eliphelele lezinto. Ngokuvamile, inani le-pH lephakathi elidingekayo ekukhuleni kweseli lingu-7.2-7.4. Ukuphakama kakhulu noma okuphansi kakhulu akusizi ukukhula kwamaseli. Imboni yamaseli isebenzisa isisetshenziswa esiwuketshezi sokukhiqiza amaseli, esingalinganiswa ngemitha ye-pH. Imitha ye-pH iyithuluzi elikhethekile lokulinganisa inani le-pH lesisombululo. Ikala i-pH yesisombululo nge-electrode yokukhetha i-pH (njenge-electrode yengilazi), futhi umphumela wokulinganisa unganemba ezindaweni ezimbili zamadesimali.
Kumelwe ilinganiswe ngesisombululo sebhafa esijwayelekile se-pH eyaziwayo (ngokuvamile i-pH 4 ~ 7) ngaphambi kokusetshenziswa. I-electrode yemitha ye-pH ihlanjululwa ngamanzi acwengekile bese icwiliswa phakathi nendawo ye-beaker, futhi i-pH yendawo ephakathi ingafundwa esikalini semitha ye-pH. Umkhiqizi ngamunye unikeza imiyalelo enemininingwane yokusebenza kwemitha ye-pH ngayinye ehlukile.
Ngemva kokulinganisa, uma inani le-pH lendawo esetshenziswa imboni yeseli lichezukile, lidinga ukulungiswa ngokufanele. Imitha ye-pH ingalinganiswa ngesixazululo esivamile sesibhafa se-pH eyaziwayo, bese i-electrode eyinhlanganisela kanye ne-thermometer yokumelana kubekwa endaweni yesiko, futhi inani elifanele le-hydrochloric acid ne-sodium hydroxide kwengezwa kancane kancane kusukela ekugcineni kwebhika kude i-electrode yokwenza isiko medium. Finyelela futhi ugcine i-pH oyifunayo.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
