Cov kev ntsuas rheological yog viscosity (cp), torque%, shear stress (dyne/cm2) thiab shear rate (s- 1).
Dab tsi yog qhov txawv ntawm rheology thiab viscosity?
Qhov sib txawv tseem ceeb ntawm rheology thiab viscosity yog qhov rheology yog kev kawm txog qhov ntws ntawm cov teeb meem, whereas viscosity yog ib qho kev ntsuas ntawm nws qhov tsis kam mus deformation. Rheology yog ib ceg ntawm physics los yog lub cev chemistry, thaum viscosity yog ib qho kev ntsuas ntau uas muaj txiaj ntsig zoo hauv chemistry.
Dab tsi yog cov khoom rheological?
Rheology cov khoom yog kev tshwm sim ntawm tus nqi thiab qhov xwm txheej ntawm deformation uas tshwm sim thaum cov khoom raug ntxhov siabCov kev txwv no tuaj yeem siv los kwv yees seb cov kua dej yuav coj li cas hauv cov txheej txheem thiab txiav txim siab lub zog xav tau rau kev thauj cov kua los ntawm ib qho mus rau lwm qhov hauv kev cog qoob loo.
Kev sib raug zoo ntawm rheology thiab viscosity yog dab tsi?
6.1 Taw qhia. Rheology txhais tau tias yog kev kawm txog kev deformation thiab ntws ntawm cov kua dej. Nws yog ib qho tseem ceeb ntawm cov khoom siv molten polymer; Nws hais txog qhov viscosity nrog qhov kub thiab txias, thiab yog li txuas rau polymer txheej txheem.
piv txwv ntawm cov khoom rheological yog dab tsi?
Piv txwv ntawm cov khoom muaj xws li elasticity, poisson ratio thiab so lub sij hawm so thiab shear modulus.
Muaj peb hom moduli yuav raug xam rau Hookan cov khib nyiab nyob ntawm txoj kev siv lub zog:
- Modulus ntawm elasticity (E)
- Modulus ntawm rigidity (G)
- Modulus of bulkiness (K)

Puas yog cov khoom lag luam newell yog cov khoom lag luam zoo los yuav?
NWL tam sim no ntaus pob ncaws pob Zacks Qib ntawm 2 (Yuav), nrog rau tus nqi qib ntawm A. Cov Tshuag muaj Forward P / E piv ntawm 14.76. Qhov no piv rau nws qhov kev lag luam qhov nruab nrab Forward P / E ntawm 22.55. Tshaj li 52 lub lis piam dhau los, NWL's Forward P/E tau siab li 17.
Puas yog kev ntshaw rau cov khoom tsis yog khoom noj?
Pica yog hais txog thaum ib tug neeg xav tau lossis noj cov khoom uas tsis yog khoom noj, xws li cov xim pleev xim lossis cov xuab zeb. Feem ntau cov kws kho mob qhia pica raws li kev noj zaub mov tsis zoo. Qee tus poj niam tuaj yeem tsim pica thaum cev xeeb tub.
Cov khoom noj khoom haus puas yuav txais cov khoom noj tas sij hawm?
khoom noj "Tsev" tuaj yeem pub dawb. Peb yuav tsum hais nws vim tsis yog txhua tus paub nws. Cov khoom noj khoom haus uas dhau los ntawm lawv cov hnub "zoo tshaj ua ntej" tau txais thiab txaus siab ntawm cov chaw pub khoom noj thiab cov tsev txhab nyiaj khoom noj thoob plaws tebchaws .
Puas cov khoom noj khoom haus puas muab cov khoom puas tsuaj?
Qhov Tseeb: Pantries muab khoom noj khoom haus tsis zoo thiab tsis lwj suav nrog: cov khoom noj siv mis, txiv hmab txiv ntoo thiab zaub tshiab, khoom ci, cov kaus poom, cov khoom qhuav, cov nqaij khov thiab lwm yam . Lub tsev txhab nyiaj puas noj cov khoom puas tsuaj?
Puas yog intercompany yog khoom vaj khoom tsev?
Intercompany Assets txhais tau tias tag nrho cov nyiaj tau txais ntawm Kev Lag Luam ntawm lossis ntawm ib lossis ntau tus Muag lossis lawv cov koom nrog. Intercompany Assets txhais tau tias cov nyiaj tag nrho vim yog Lub Tuam Txhab los ntawm txhua tus koom tes ntawm Lub Tuam Txhab .
