Kev Them Nqi Tshwj Xeeb ntawm Cov Khoom Siv Hluav Taws Xob (Tso Tseg Ib Ntus)

Kev Taw Qhia

Cov cuab yeej siv lub zog sib nqus uas tsim los ntawm Helmholtz kauj los tswj kev txav ntawm cov hluav taws xob hauv Lorentz lub raj xa hluav taws xob los txiav txim siab qhov them hluav taws xob tshwj xeeb. Nws muaj Lorentz lub raj xa hluav taws xob (qhov ntsuas ua ke), Helmholtz kauj, lub zog muab hluav taws xob thiab lub taub hau ntsuas, thiab lwm yam. Tag nrho yog teeb tsa hauv lub thawv ntoo tsaus, uas yooj yim rau kev soj ntsuam, ntsuas thiab tswj.

Cov ntsiab lus tseem ceeb ntawm kev sim:

1, Kev soj ntsuam ntawm deflection ntawm electron beam nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb;

2, Kev soj ntsuam ntawm txoj cai ntawm kev txav mus los ntawm kev txav mus los hauv lub teb sib nqus hauv qab kev ua ntawm Lorentz lub zog;

3, Kev txiav txim siab ntawm cov nqi tshwj xeeb ntawm electron.

Cov kev tsis tseem ceeb

1, Lorentz lub raj xa dej txoj kab uas hla 153 hli, puv nrog cov roj inert, ua-hauv nplai, nplai ntev 9cm;

2, Lorentz lub raj xa dej tuaj yeem tig tau, lub kaum sab xis ntawm kev tig 350 degrees, nrog rau qhov ntsuas qhia;

3, Deflection voltage 50 ~ 250V kho tau tas li, tsis muaj 'meter' zaub;

4, Qhov hluav taws xob nrawm 0 ~ 250V hloov kho tas li, kev tiv thaiv tam sim no ua tiav, lub ntsuas hluav taws xob digital ncaj qha tso saib qhov hluav taws xob Qhov kev daws teeb meem yog 1V;

5, kev txhawb zog tam sim no 0 ~ 1.1A kho tau tas li, lub ntsuas digital ncaj qha tso saib tam sim no, kev daws teeb meem 1mA;

6, Helmholtz kauj vojvoog zoo 140 hli, ib kauj tig 300 tig;

7, lub thawv ntoo khov kho, lub thawv ntoo loj 300 × 345 × 475mm 8, qhov yuam kev ntsuas hluav taws xob rau qhov hnyav zoo dua 3%.
