Indawo emaphakathi isho imvelo yezakhi ezilingisa ngokuzenzela ukukhula kwamangqamuzana emzimbeni, futhi inikeze ukukhula nokukhiqizwa kabusha kwamagciwane, izitshalo noma izilwane (noma izicubu), futhi iyi-matrix yezakhi ezilungiswa ngokuhlanganisa imisoco ehlukene. Kufanele igcinwe kanjani into esetshenziswayo futhi yiziphi izidingo zamabhodlela mediaAmabhodlela ?
Ukugcinwa kwendawo kufanele kulandele lezi zimiso ezilandelayo:
1. Indawo yezohwebo kufanele igcinwe ngokuhambisana nezidingo encwadini yeziqondiso. Ilebula yolimi kufanele imakwe ngenombolo yeqoqo, usuku lokukhiqiza, usuku lokuphelelwa yisikhathi kanye nezici ezifanele zale ndlela. Izimo zokulondoloza nezokuthutha ezisetshenziswayo kufanele zinciphise ukulahlekelwa umswakama endaweni ephakathi nendawo futhi zinikeze ukuvikeleka komshini.
2. Indawo elungisiwe kufanele igcinwe ku-2 ~ 25 ℃ endaweni emnyama. Uma igcinwe esitsheni esingangeni moya, ngokuvamile isetshenziswa phakathi namasonto amathathu; uma igcinwe esitsheni esivaliwe, ngokuvamile isetshenziswa phakathi nonyaka owodwa. I-agar medium akufanele igcinwe ngaphansi noma ngaphansi kuka-0 °C ukuvimbela ukuqhwa ekulimazeni izakhiwo zejeli. Uma okuphakathi kuzogcinwa isikhathi eside, amapuleti e-agar kufanele ahlanganiswe ngokuqinile noma afakwe esitsheni esingenawo umoya ukuze avimbele ukulahlekelwa kwamanzi.
3. I-medium kufanele ikhishwe ngokushesha ngemva kokuvalwa inzalo, futhi akufanele igcinwe ku-autoclave ukugwema ukuphazamisa ikhwalithi ye-medium. Indawo elungisiwe kufanele igcinwe ku-2-25°C endaweni emnyama.
4. Gcina esitsheni esingangenisi umoya ukuze uvimbele ukulahleka komswakama futhi welule isikhathi sokuwugcina.
5. Ukuncibilika kabusha kwendawo eqinile ngemuva kokuvalwa inzalo kufanele kwenziwe kubhavu wamanzi ashisayo noma kusetshenziswa isitimu esijikelezayo, kuvunyelwe isikhathi esisodwa kuphela, kanti indawo encibilikisiwe kufanele ibekwe endaweni yokugeza amanzi ngo-45-50 ° C kungabe kusaba khona. kunamahora angu-8.
Isisetshenziswa sisetshenziswa kakhulu kusikompilo lwamaseli. Ngenxa yezidingo eziphakeme uma kuqhathaniswa ngendawo edingekayo yokukhula kweseli, ukuze kuqinisekiswe ukuthi okuphakathi akungcolisiwe, ibhodlela eliphakathi ngokuvamile livalwa inzalo ngemishayo yama-electron, ukuze lingabi nayo i-DNase, i-RNase, kanye Nomthombo wokushisa. Ukuze kube lula ukubhekwa komthamo we-medium, izinto zokusetshenziswa zamabhodlela emidiya ikakhulukazi izinto ze-polyester ezinokucaca okuphezulu, futhi izikali ezithile zizomakwa emzimbeni webhodlela.
Njengesakhi esibalulekile sokukhula kwamaseli, ukuthi i-medium igcinwe kahle ihlobene nokukhula okuvamile kwamaseli. Lapho ukhetha ibhodlela lemidiya, kufanele kuqashelwe ngokukhethekile ukuthi liyahlangabezana yini nezidingo zesitoreji se-medium.
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.
