Millikan Oil Drop Apparatus

 

Tsawg heev yuam kev tus nqi

Lub Millikan Oil Drop Apparatus muaj qhov cuam tshuam qhov nruab nrab ntawm tsawg dua 2%, uas yog qhov zoo heev rau cov tub ntxhais kawm lub chaw soj nstuam. Qhov sib npaug phaj sib nrug yog 5.00 hli, nrog qhov tseeb ntawm ± 0.01 hli. Lub phaj voltage ranges ntawm 0 mus rau 680 V DC, nrog xaiv qhov zoo, xoom, thiab qhov tsis zoo, thiab hloov tau polarity. Qhov hluav taws xob sib npaug ntawm 0 txog 350 V DC. Lub lifting voltage yog tsis siv neeg thiab yog teem rau 140% mus rau 160% ntawm qhov nyiaj tshuav voltage. Cov nyees khawm yog tsim los tiv thaiv ntau tshaj ib lab kev ua haujlwm.

Cov cuab yeej no qhia txog qhov hluav taws xob ntawm lub vijtsam digital, nrog rau ntau yam ntawm 0 txog 999 V thiab qhov tseeb ntawm 1 V. Lub sijhawm timer yog li ntawm 0 txog 99.99 vib nas this, nrog qhov tseeb ntawm 0.01 vib nas this. Qhov ua tau- hauv kev ntsuas ntsuas muaj qhov sib txawv ntawm 2 hli thiab txhawb nqa ob qhov kev faib: 0.25 hli thiab 0.04 hli rau ib ntu. Lub microscope muab 60 × magnification. Lub CCD sensor muaj siab rhiab heev ntawm 0.01 lx, nrog rau kev daws teeb meem ntawm 600 TV kab. Cov tub ntxhais kawm tuaj yeem ua qhov kev sim uas siv cov txheej txheem dynamic lossis zoo li qub. Lub apparatus kuj suav nrog cov ntaub ntawv ua software.

Cov cuab yeej tuaj yeem khaws cov roj tee kom ruaj khov rau ntau tshaj ib teev thiab tuaj yeem taug qab cov dej xau tau ntev tshaj li ob teev. LED illumination xyuas kom meej tias cov tee dej tshwm ci ntsa iab thiab meej. Lub 15-inch xim saib qhia cov txiaj ntsig kev soj ntsuam. Txawm hais tias peb yuav tsis muaj kev paub dhau los ua haujlwm nrog cov khoom lag luam thoob ntiaj teb, peb cov khoom lag luam zoo tau txais kev ntseeg siab ntawm ze li ntawm 1,000 lub tsev kawm ntawv. Peb muab ib qho - xyoo lav, thiab peb pab neeg tom qab muag tau npaj los muab kev txhawb nqa. Cov cuab yeej no yog ib qho ntawm peb cov khoom nrov tshaj plaws.
