Hujayra madaniyati uchun keng tarqalgan ishlatiladigan sarf materiallaridan biri sifatida hujayra madaniyati kolbalari hujayralarning o'sishi va ko'payishida muhim rol o'ynaydi. Hozirgi vaqtda bozorda hujayra madaniyati idishlari asosan shisha yoki plastmassa materiallardan tayyorlangan. Ushbu turdagi sarf materiallari oddiy tibbiy plastik butilkalardan farq qiladi va narxi nisbatan yuqori. Bunday idishlarni qayta ishlatish mumkinmi?
Agar siz shisha hujayra kulturasidan foydalansangiz, toza suvda 30 daqiqadan ko'proq vaqt davomida namlashingiz, ozgina tozalash vositasi qo'shishingiz, ultratovush bilan ko'proq yuvishingiz mumkin. 30 daqiqa, olib tashlang va quriting, so'ngra 6-18 soat davomida xrom kislotali losonga botiring, keyin 10-15 marta musluk suvi bilan yuving, 3-4 marta ikki marta distillangan suv bilan yuving, quriting va qayta ishlatishdan oldin avtoklavda o'tkazing.
Mavjud hujayra madaniyati kolbalarining aksariyati plastik materiallardan tayyorlangan va ularning aksariyati bir martalik ishlatiladi va ko'pi bilan bir necha avlod hujayralarni o'tkazishi mumkin. Ammo hujayralar atrof-muhitga nisbatan sezgirroqdir. Agar ular ko'p marta qayta ishlatilsa, hujayra o'sishi bilan ajralib chiqadigan moddalar va o'lik hujayralarning qoldiq moddalari shishada qoladi va yangi hujayralar o'sishiga ta'sir qiladi. Bundan tashqari, hujayra madaniyati kolbalarida hujayra yopishishi va o'sishiga yordam beruvchi omillar mavjud. Ko'proq o'tishlar bilan bu omillar sekin o'sib boradi. Shuning uchun bu hujayra o'sishi holatiga bog'liq. Umuman olganda, 2-3 avlod yaxshi. 3 Uni avloddan keyin almashtirish tavsiya etiladi.
Umuman olganda, yaxshi o'sishi uchun hujayra kulturalari dan qayta foydalanish tavsiya etilmaydi. Hujayralarni etishtirish uchun ishlatiladigan madaniyat muhiti va sarum bilan solishtirganda, sarf materiallari narxini eslatib o'tmaslik kerak. Albatta, hujayralar an'anaviy tarzda ko'paya oladimi, nafaqat yangi va eski hujayra madaniyati idishlariga, balki aseptik operatsiyaga e'tibor berishingizga ham bog'liq. Agar operatsiya jarayoni noto'g'ri bo'lsa, hatto eng yaxshi shishalar ham hujayra o'sishiga ta'sir qiladi.
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.
