Cellularum incrementum non solum ab uberibus nutrimentis pendet, sed etiam intra valorem pH valoris aptum esse debet ad incrementum et reproductionem normalem. Ideo, antequam usus @___@ cellae culturae magnarum, pH valor medii metiri debet et adaptari prius.the pH valor refert ad rationem totius numeri hydrogenii. in solutione ad summam substantiarum. Fere pH valor medii ad incrementum cellularum requisitum est 7.2-7.4. Excelsa vel humilis nimis cellae incrementum non conducit. Officina cellula media liquido utitur ad cellulas colendas, quae cum pH metro metiri possunt. pH metrum speciale instrumentum est ad solutionis valorem pH metiendam. pH solutionis mensurat per electrum pH electrum (ut electrode vitreum), et effectus mensurae accurate duobus locis decimalibus esse potest.cell officina
Calibrari debet cum norma quiddam solutionis notae pH (plerumque pH. 4~7) ante usum. Electrode pH metri lavatur aqua destillata et immergitur in medio POCULI, et pH medii a scala pH metri legi potest. Unusquisque opifex singulas instructiones pH metri singulas operans praebet.
Post mensurationem, si pH valor medii usus est a officina cella deflexerit, necesse est proinde accommodari. Metrum pH calibrari potest cum solutione quiddam mensurae notarum pH, tum compositi electrode et resistentia thermometri in medio culturae positae, et congrua copia acidi hydrochlorici et sodium hydroxidi lente a fine POCULI amovetur. Electrode ad culturae medium. Porrige et tene optatam Ph.
After the measurement, if the pH value of the medium used by the cell factory is deviated, it needs to be adjusted accordingly. The pH meter can be calibrated with a standard buffer solution of known pH, then the composite electrode and resistance thermometer are placed in the culture medium, and an appropriate amount of hydrochloric acid and sodium hydroxide are slowly added from the end of the beaker away from the electrode to make the culture medium. Reach and maintain the desired pH.
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.
