Nyhuv ntawm kub ntawm kev xeem cov ntaub ntawv ntawm yaj khiav Performance index tester

Vim hais tias nyob hauv kev ntsuam xyuas cov tawv nqaij, tsuas yog qhov ntsuas kub yog qhov dynamic parameter, yog li qhov feem ntawm kev xeem tau los kuj tseem loj heev, vim li ntawd peb yuav tsum qhia meej txog cov kev tsis zoo ntawm qhov kub ntawm qhov kev xeem.

1. Kub qhov tseeb.

Tshuaj ntsuam index kuaj qhov tseeb, qhov twg qhov txawv nruab nrab ntawm tus nqi exponential thiab tus qauv ntsuas kub. Feem ntau, yog tias qhov kev tswj qhov kub kub muaj qhov ntev ntev thiab kev hloov me me, qhov tseeb yuav raug kho kom tshem tawm qhov yuam kev. Feem ntau (raws li ISO cov qauv,) yuav tsum tau ua kom tsis pub dhau 0.5 ° C.

2. Hlav kub txawv

Kub fluctuation hais txog qhov ntsuas kub ntawm qhov khoom ntsuas tom qab pub mis los yog tsis tau, thiab qhov kub yog qhov ruaj khov. Qhov no txhais tau tias qhov kub tswj kev muaj peev xwm ntawm cov khoom siv.

3. Kev ruaj ntseg ntev ntev

Kev ntsuam xyuas kev ntsuam xyuas tawv stability yog hais txog qhov hloov ntawm qhov kub hloov tom qab lub sij hawm ntev, xws li 4 x, seb nws yog noj los yog tsis nyob hauv lub thoob. Nws txhais tau tias qhov kub tswj qhov peev xwm los tiv thaiv kev kub hloov ntawm ib puag ncig, tiv thaiv lub hwj huam hloov hluav taws xob, thiab nws tus kheej. Kev hloov ntawm kev siv hluav taws xob. Feem ntau tsis tas yuav tsum tau tshaj 1 ° C.

4. Kub Tshaj Plawg

Tshwj xeeb, nws yog hais txog qhov kub thiab txias ntawm qhov ntev ntawm 50 hli los ntawm qhov kawg ntawm tus tuag nyob hauv lub thoob, rov qab qhia txog qhov sib txawv ntawm qhov ntsuas kub hauv lub thoob. Nws feem ntau yuav tsum tsis txhob pub tshaj ± 1.5 ° C ntawm sab saum toj ntawm qhov kub thiab ± 1 ° C ntawm qab
