Hujayra fabrikalarikatta hajmdagi hujayra madaniyatida muhim rol o'ynaydi. Hozirgi vaqtda hujayra zavodlarining umumiy spetsifikatsiyalari 1, 2, 5, 10, 40 va hokazo. Turli qatlamlarga mos keladigan madaniyat maydoni ham har xil, shuning uchun har xil. Spetsifikatsiyadagi hujayra zavodida qancha hujayra emlash mumkin?
Har bir turdagi hujayraning o'sish xususiyatlari va emlash zichligi va atrof-muhitga qo'yiladigan talablar har xil bo'lgani uchun hujayra zavodining har bir o'lchami bilan qancha hujayrani emlash mumkinligini umumlashtirib bo'lmaydi. Hujayra urug'ining zichligi urug'langan tirik hujayralar zichligiga ishora qiladi, bu hujayra o'sishi va yashashiga katta darajada ta'sir qiladi. Inokulyatsiya kontsentratsiyasi past bo'lsa, hujayra o'sishi va ko'payishi sekinroq bo'ladi va oxirgi hujayra hosildorligi ham past bo'ladi, ayniqsa, yopishgan hayvonlar hujayralari uchun. Emlash kontsentratsiyasi ma'lum bir kritik qiymatgacha past bo'lsa, hujayralar hatto muhit yuzasida kengaymaydi. Turli hujayra qatorlari har xil mos hujayra ekish zichligiga ega.
Odatda tadqiqotchilar hujayra zavodining birlik maydoniga to'g'ri keladigan hujayralar sonini emlashi, uni ishlatilgan hujayra zavodi madaniyati maydoniga ko'paytirishi va emlash nisbati bo'yicha bo'lishlari tavsiya etiladi. madaniyatli hujayralar. Juda yuqori yoki juda past hujayrali emlash miqdori hujayraning ko'payishiga yordam bermaydi. To'g'ri hujayra emlash miqdori hujayralarning normal o'sishini ta'minlash uchun zaruriy shartdir.
hujayra fabrikasi. ixcham maydonda hujayra madaniyatining katta maydonini amalga oshirish uchun ko'p qatlamli stacked strukturadan foydalanadi. Hujayra kulturalari bilan solishtirganda, hujayra emlash soni kengaytirildi va uning keng miqyosli hujayra madaniyatidagi roli tobora ko'proq namoyon bo'ldi.
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.
