Txhawm rau pib, tsuas yog square tus nqi ntawm txhua tus tsis paub meej qhov chaw. Tom ntej no, ntxiv lawv tag nrho ua ke rau xam lub sum (piv txwv li lub sum ntawm squares). Ces, xam tus square-hauv paus ntawm tus nqi summed (piv txwv li lub hauv paus sum ntawm squares). Qhov tshwm sim yuav yog koj Combined Tsis paub meej.

Kuj paub, koj pom qhov kev sim tsis paub meej li cas?

Tsis paub meej yuav luag ib txwm hais rau ib tus lej tseem ceeb (piv txwv: ± 0.05 s). Yog tias tsis paub meej pib nrog ib qho, qee cov kws tshawb fawb hais txog qhov tsis paub meej rau ob tus lej tseem ceeb (piv txwv: ± 0.0012 kg). Ib txwm puag ncig kev sim ntsuas los yog qhov tshwm sim rau tib qhov chaw decimal raws li qhov tsis paub meej.

Ib tug kuj yuav nug, ua li cas koj txo qhov kev sim tsis paub tseeb? Txhawm rau pab cov koom haum ua tiav lub hom phiaj no, kuv tau sau ib daim ntawv teev npe ntawm peb txoj hauv kev ua tau zoo los txo qhov ntsuas qhov tsis paub tseeb.

  1. Kuaj thiab sau cov ntaub ntawv. "Nrhiav kev sib xyaw ua ke uas ua rau muaj qhov sib txawv tsawg dua.
  2. Xaiv ib lub calibration Laboratory zoo dua.
  3. Tshem tawm Bias thiab Characterize.

Kuj kom paub, koj ua li cas xam qhov tsis paub tseeb?

Cov tsis paub meej ntawm qhov ntsuas ntsuas yog kwv yees li ntxiv lossis rho tawm (±) ib nrab ntawm qhov ntsuas qhov tsawg tshaj plaws. Rau tus pas ntsuas kub nrog lub cim ntawm txhua 1.0 ° C, qhov tsis paub meej yog ± 0.5 ° C. Qhov no txhais tau hais tias yog tus menyuam kawm ntawv nyeem tus nqi ntawm qhov ntsuas kub no li 24.0 ° C, lawv tuaj yeem muab qhov tshwm sim li 24.0 ° C ± 0.5 ° C.

Dab tsi yog qhov kev sim tsis paub tseeb hauv chemistry?

Kev sim tsis paub meej tsom xam yog ib tug txheej txheem uas tsom xam ib tug derived kom muaj nuj nqis, raws li cov tsis paub meej nyob rau hauv qhov kev sim ntsuas qhov ntau uas yog siv nyob rau hauv qee hom kev sib raug zoo ntawm kev ua lej ("model") los xam cov khoom uas tau muab los. Tsis paub meej tsom xam feem ntau hu ua "kev nthuav tawm ntawm qhov yuam kev."
