Hujayra madaniyati ma'lum bir o'sish muhitida hujayralarning omon qolishi, o'sishi, ko'payishi va asosiy tuzilmalari va funktsiyalarini saqlab turish usulini anglatadi. Hujayra fabrikalari ko'pincha keng miqyosli hujayra madaniyati uchun ishlatiladi va ularning qopqoqlari ular ishlatiladigan muhitga qarab farq qiladi.
Hujayralarning o'sish muhiti bepushtlik, mos haroratni (37) o'z ichiga oladi. ～38℃), osmotik bosim (260～320mmol/L), karbonat angidrid va mos pH (7,2～7.4). Hujayra zavodlari odatda hujayra madaniyati uchun inkubatorlar va issiqxonalardan foydalanishlari kerak. Turli xil foydalanish muhitiga ko'ra, shisha qopqoqlari ikki turga bo'linadi: sterilizatsiya va ventilyatsiya qopqoqlari va muhrlangan qopqoqlar.
Sterilizatsiya va nafas oladigan qopqoq: Bu qopqoqning yuqori qismida shamollatish teshiklari mavjud va asosan karbonat angidrid muhitida ishlatiladi. Nafas oladigan qopqoq atrof-muhitdagi karbonat angidridning hujayra zavodiga kirishiga imkon beradi va hujayra o'sishi uchun mos o'sish sharoitlarini yaratadi. Bundan tashqari, bu qopqoq, shuningdek, sterilizatsiya funktsiyasiga ega bo'lib, asosan bakteriyalarning konteynerga kirishiga, hujayralarni ifloslanishiga va ularning normal o'sishiga yo'l qo'ymaydi.
Muhrlangan qopqoq: Bu qopqoqda shamollatish teshiklari yo'q va asosan karbonat angidridsiz sharoitlarda ishlatiladi. inkubatorlar va issiqxonalar sifatida. Muhrlangan qopqoq tashqi bakteriyalarning kirib kelishini oldini oladi va hujayra o'sishi uchun yaxshi o'sish muhitini yaratishga yordam beradi.
Hujayra fabrikasining sterilizatsiya va ventilyatsiya qopqog'i va muhrlangan qopqog'i turli xil madaniyat muhitlarida qo'llaniladi, bu juda katta ahamiyatga ega. hujayra o'sishi uchun zarur bo'lgan muhit xavfsizligi. Yaxshi o'sishi mumkin.
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.
