Hujayra kulturalarilaboratoriyada o'rta miqyosdagi hujayra va to'qimalar madaniyatida muhim rol o'ynaydi. Umumiy spetsifikatsiyalar 25cm2, 75cm2, 175cm2 va 225cm2 ni o'z ichiga oladi, ular turli o'lchamdagi hujayra madaniyati ehtiyojlarini qondira oladi. Oddiy plastik butilkalardan farqli o'laroq, hujayra madaniyati kolbalari dizaynidagi innovatsiyalar quyidagi jihatlarda o'z aksini topgan:
1. Darboğaz: hujayra madaniyati kolbasining bo'g'ozi tortikollis bilan ishlab chiqilgan va pastki qismi yoy shaklida bo'lib, kultura eritmasini eksport qilish uchun qulaydir. Darboğaz nisbatan keng va o'lik burchak yo'q, shuning uchun pipetka va hujayra qirg'ichlari shishaning har bir burchagiga chuqur kirib borishi mumkin va operatsiya qulayroq.
2. Shisha qopqog'i: Ushbu hujayra sarf materiallari turli xil madaniyat muhitlari uchun mos bo'lgan ikki xil shisha qopqoq bilan jihozlangan. Sızdırmazlık qopqog'i to'liq yopiq holatda va qopqoqda hech qanday teshik yo'q. U asosan inkubatorlar va issiqxonalar kabi karbonat angidridsiz sharoitlarda qo'llaniladi. Nafas oluvchi qopqoqning yuqori tomoni nafas oladigan teshiklar bilan ta'minlangan, bu teshiklar atrof-muhitdagi karbonat angidridni shishaning ichki qismiga kiritishi va hujayra o'sishi uchun mos o'sish sharoitlarini yaratishi mumkin.
3. Muzli: Hujayra madaniyati tajribasi jarayoni qayd etilgan. Shishaning tortikollis qismi muzli yozuv joyi bilan püskürtülür, bu ilmiy tadqiqotchilar uchun ma'lumotni belgilash uchun qulaydir.
4. Yig'ish: Hujayra madaniyati kolbasining pastki qismida ventilyatsiya qiluvchi spikerlar mavjud bo'lib, ular shishalar orasidagi harorat muvozanatini saqlash va yig'ishni osonlashtiradi.
Yuqoridagilar hujayra madaniyati kolbalari ning funktsional yangiliklari. Ushbu maxsus dizaynlar eksperimentatorlar uchun qulay va hujayra madaniyati tajribalarining muammosiz rivojlanishiga ko'proq yordam beradi.
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.
