ning fizik va kimyoviy sinovi hujayra zavodi sifatini tekshirishning juda muhim jihati hisoblanadi. U bir qator sinov ob'ektlarini o'z ichiga oladi, jumladan, yonishdagi qoldiqlar, yuviladigan moddalarni sinash, metall elementlar va boshqalar. Bu sinovlar asosan xom ashyo tarkibida hujayra o'sishi kimyoviy moddalariga ta'sir qilishini aniqlash, shu bilan hujayra madaniyati xavfsizligini ta'minlash. Yonayotganda qoldiq: Organik preparat karbonizatsiya yoki noorganik preparatni isitish orqali parchalangandan so'ng, uni namlash uchun sulfat kislota qo'shing va keyin past haroratda, keyin esa yuqori haroratda (700-800 ° C) yondiring. toʻliq kul boʻladi, organik moddalar parchalanadi va uchuvchan boʻladi, qolgan uchuvchan boʻlmagan noorganik aralashmalar (koʻproq Metall oksidi yoki noorganik tuzlar) sulfatlarga aylanadi, ular yonganda qoldiqlar deb ataladi. Ushbu test, asosan, xom ashyoning tozaligini baholash uchun hujayra zavodining ishlab chiqarish xom ashyosidagi aralashmalar standartdan oshib ketishini aniqlash uchundir.hujayra. fabrika
Eritish testi: materialning erish darajasi va erigan moddalarning xavfsizligi. ishlab chiqarish, saqlash va tashish jarayonida polimer materiali mahsulotlari va suyuq mahsulotlar o'rtasida uzoq muddatli aloqadan so'ng, shu jumladan qabariq sinovi, pH o'zgarishi testi, ionlash, xlorid ionini aniqlash, og'ir metallar Tarkibni aniqlash, bug'lanish qoldiqlari, kaliy permanganat iste'moli, UV nurlanishi va boshqalar.
Metallar: Metalllar hujayra madaniyatining ishlashiga va tegishli terapevtik protein mahsulotlari sifatiga ta'sir qiluvchi asosiy xom ashyoning atributlari. Mis, magniy hujayra o'sishi, oqsil ifodasi, glikoformlar kabi ko'plab metabolik yo'llarda kofaktorlar va reagentlar rolini o'ynaydi va shuning uchun elementar monitoringni talab qiladi.
Yuqoridagilar hujayra zavodining fizik va kimyoviy sinov elementlaridir. Bu ko'plab testlarning faqat bitta jihati. Mahsulotning umumiy sifatini ta'minlash uchun, shuningdek, biologik sinov, jarayon sinovi, hujayra o'sishi testi, hujayra va zarracha kafolati va boshqa sinovlarni o'z ichiga oladi.
The above are the physical and chemical testing items of the cell factory. This is only one aspect of many tests. To ensure the overall quality of the product, it also includes biological testing, process testing, cell growth testing, cell and particle assurance and other testing.
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.
