Kev daws teeb meem rau Coarse Adjustment Mechanism of the Microscope
Cov kev ua txhaum loj ntawm lub tshuab ntsuas qhov ntxhib hloov kho tshuab suav nrog kev tsis siv neeg swb thiab tsis sib xws nruj thaum nqa thiab txo qis. Tsis siv neeg slipping yog hais txog qhov tshwm sim uas lub thoob, caj npab los yog theem maj mam drifts downward spontaneously nyob rau hauv nws tus kheej qhov hnyav yam tsis muaj kev hloov kho thaum nws nyob twj ywm ntawm ib qho chaw. Qhov kev txhaum no tshwm sim thaum lub zog gravitational ntawm lub thoob, caj npab lossis theem siab tshaj qhov kev sib txhuam zoo li qub. Qhov kev daws teeb meem yog txhawm rau ua kom muaj kev sib txhuam zoo li qub kom nws tshaj qhov hnyav ntawm lub thoob los yog caj npab.
Rau inclined-tube microscopes thiab coarse adjustment assemblies ntawm feem ntau binocular microscopes, yog hais tias lub caj npab slips down cia li, tuav lub anti-slip ceev nyob rau hauv lub ntxhib focusing handwheel nrog ob txhais tes thiab nruj nreem clockwise kom tsis txhob slipping. Yog tias txoj kev no ua tsis tiav, hu rau cov neeg ua haujlwm kho mob.
Thaum lub microscope chim plam cia, nws yog feem ntau yuam kev xav tias lub iav thiab khib mesh dhau xoob. Qee cov neeg siv yuav ntxiv shims hauv qab khib. Txawm hais tias qhov no tuaj yeem tso tseg ib ntus, nws tso cov iav thiab khib rau hauv qhov txawv txav meshing. Kev txav mus tas li yuav deform ob lub iav thiab khib. Deformation ntawm lub khib yuav hnyav heev yog hais tias lub shim tsis sib xws, ua rau tsis sib xws meshing - nruj nyob rau hauv ib co seem thiab xoob nyob rau hauv lwm tus neeg. Yog li ntawd, txoj kev no tsis pom zoo.
Tsis tas li ntawd, yog tias qhov kev hloov kho ntxhib tsis tau khaws cia rau lub sijhawm ntev thiab cov roj lubricating tau qhuav lawm, kev ua haujlwm nqa yuav hnov tsis zoo, thiab kev sib txhuam suab nrov ntawm qhov chaw tseem yuav hnov. Nyob rau hauv rooj plaub no, disassemble lub mechanical assembly, ntxuav nws, siv roj thiab reassemble nws.
