Craftsmanship of Basic Physics Experimental Instruments

Cov txheej txheem tsim khoom rau cov cuab yeej siv lub cev hauv lub sim ntsuas feem ntau ua qhov tseem ceeb rau qhov tseeb thiab sib xws. Thaum lub sij hawm tsim khoom, cov khoom tseem ceeb tau ua tiav kev ua haujlwm tiav -xws li tig, milling, thiab sib tsoo -kom paub meej tias qhov ntev ntev nyob rau hauv cov kev txwv uas tau txais. Rau cov khoom tseem ceeb uas cuam tshuam nrog kev ntsuas, kev nplua ntxiv - cov txheej txheem ua tiav thiab calibration yog siv los txo cov kev ua yuam kev ntawm qhov chaw, yog li lav qhov kev ntsuas txhim khu kev qha thaum lub sijhawm ntsuas kev ua haujlwm.

Hais txog cov txheej txheem sib dhos, cov khoom sib dhos yog sib sau ua ke thiab debugged hauv kev ua raws li cov txheej txheem tsim. Cov txheej txheem sib dhos yuav tsum tsis yog tsuas yog ua kom muaj kev sib txuas ruaj ntseg nkaus xwb tab sis kuj ua tib zoo saib xyuas qhov haum ntawm cov khoom nyob ib sab.

Kev kho deg thiab kev tswj kom zoo yog qhov tseem ceeb ntawm cov txheej txheem sib npaug. Cov khoom siv hlau feem ntau raug kho saum npoo av-xws li kev pleev xim, electroplating, lossis anodizing- txhawm rau txhim kho lawv cov kev tiv thaiv corrosion thiab kev zoo nkauj, thaum cov yas lossis iav cov khoom raug soj ntsuam feem ntau raws li lawv cov molding zoo thiab nto tiav. Thoob plaws hauv tag nrho lub voj voog tsim khoom, kev tshuaj ntsuam xyuas zoo tau tswj xyuas los txheeb xyuas qhov tseem ceeb ntawm cov khoom siv los ntawm cov khoom, yog li xyuas kom txhua lub cuab yeej ua haujlwm ruaj khov thiab ntseeg tau hauv qhov chaw kawm thiab kev sim.
