Likarolo tse ikhethang tsa terata ea ho hanyetsa Karma

1) Ho qala ka terata ea motlakase ea mocheso ea Nickel Chromium Sehlopha sa 1, re nkile sebaka sa tse ling tsa Ni ka
Al le likarolo tse ling, kahoo li fihlelletse thepa ea ho hanyetsa ka ho nepahala ka ntlafatso
coefficient ea mocheso oa khanyetso le matla a motlakase a mocheso khahlanong le koporo.
Ka ho eketsoa ha Al, re atlehile ho etsa hore ho hanyetsa molumo ho be hoholoanyane ka makhetlo a 1.2.
ho feta terata ea motlakase ea mocheso ea Nickel Chromium Sehlopha sa 1 'me matla a ho thaepa a phahame ka makhetlo a 1.3.

2) Koefficient ea mocheso oa bobeli β ea terata ea Karmalloy KMW e nyane haholo, - 0.03 × 10-6/ K2,
'me mothapo oa mocheso oa khanyetso o fetoha mola o otlolohileng ka hare ho sephara se seholo
mocheso o fapaneng.

Ka hona, tekanyo ea mocheso e behiloe hore e be tekanyo ea mocheso e tloaelehileng pakeng tsa
23 ~ 53 °C, empa 1 × 10-6/K, karolelano ea mocheso pakeng tsa 0 ~ 100 °C, le eona e ka ba
e amoheloe bakeng sa tekanyo ea mocheso.

3) Matla a motlakase khahlanong le koporo a pakeng tsa 1 ~ 100 °C le ona a manyane, a ka tlase ho + 2 μV/K, mme
e bonts'a botsitso bo babatsehang ka nako ea lilemo tse ngata.

4) Haeba sena se tla sebelisoa e le thepa ea ho hanyetsa ka nepo, kalafo ea mocheso o tlase ke
e hlokahalang ho felisa ho sotha ha ts'ebetso feela joalo ka ha ho bile joalo ka terata ea Manganin CMW.

Re boetse re hlahisa mofuta o mong oa terata ea khanyetso joalo ka NiCr 80/20, NiCr 70/30, Nicr 60/15, Cr25Al5, jj.
