Hujayralarning o'sishi atrof-muhitga, haroratga, pH qiymatiga va boshqalarga juda qattiq talablarga ega va hujayralarni etishtirishda ishlatiladigan hujayra sarf materiallarining sifati ham hujayralar o'sishiga ta'sir qiladi. Hujayra fabrikalari yopishgan hujayra madaniyati uchun keng tarqalgan ishlatiladigan sarf materiallari bo'lib, ularning sifatiga ta'sir qiluvchi to'rtta asosiy omil mavjud.
1. Ishlab chiqarish xomashyosi: Yuqori sifatli xom ashyo yuqori sifatli mahsulotlarning asosidir. Hujayra zavodining xom ashyosi polistirol (PS) bo'lib, USP VI sinfining talablariga javob berishi kerak. So'z talablari tibbiy sohada plastik materiallarni va biofarmatsevtikada quvur liniyasi mahsulotlarini sinab ko'rishdir. Bu sohada qo'llaniladigan yanada qattiqroq testlar turli eksperimental spetsifikatsiyalarga mos keladigan klinik bo'lmagan laboratoriya tadqiqotlaridir.
2. Ishlab chiqarish muhiti: hujayralar o'sish muhitiga ayniqsa sezgir, shuning uchun sarf materiallarida endotoksin kabi hujayralar uchun zararli moddalar bo'lmasligi kerak, bu ularning ishlab chiqarish muhitiga yuqori talablarni qo'yadi. Sarf materiallari maxsus 10 000 toifali toza xonada ishlab chiqarilishi va qat'iy tekshiruvdan (plankton, cho'kindi va to'xtatilgan zarrachalarni aniqlash) o'tishi va ishlab chiqarish muhitining barqarorligini ta'minlash uchun GMP ustaxonalariga muvofiq sifat menejmentini amalga oshirishi kerak.
3. Ishlab chiqarish jarayonini nazorat qilish: Bu mahsulotning barcha jihatlarini ishlab chiqarish jarayoniga kiritishni nazarda tutadi, masalan, inyeksion kalıplama parametrlari, quyish harorati va boshqalar, bu tayyor mahsulot sifatiga ta'sir qiladi.
4. Sifatni tekshirish: Sifatni tekshirish hujayra zavodi ishlab chiqarilgandan keyin muhim jarayondir. Tekshirilishi kerak bo'lgan narsalar qatoriga muhrlash, biologik xavfsizlik, fizik va kimyoviy xavfsizlik, mahsulotning amal qilish muddatini tekshirish, sirtning gidrofilligi va boshqalar kiradi, bu tekshiruvlar orqali mahsulot sifat standartlariga muvofiqligini aniqlash uchun.
Sifatga ta'sir qiluvchi omillar. hujayra zavodlari asosan yuqoridagi to'rt jihatni o'z ichiga oladi. Faqatgina ushbu omillarni nazorat qilish orqali yuqori sifatli mahsulotlarni ishlab chiqarish mumkin, bu esa hujayra o'sishi uchun yaxshi muhitni ta'minlaydi.
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.
