Engineering Case

Cov ntsiab lus tseem ceeb ntawm engineering tiv thaiv
1.Nkag mus: Feem ntau, thaum qhov siv hluav taws xob (tube voltage) ntawm X-rays> 400Kv, yuav tsum tau teeb tsa txoj kev taug kev (poob) ntawm qhov nkag, thiab cov kev taug kev yuav tsum tau teeb tsa rau gamma rays, neutrons, thiab cov khoom nrawm. .

2.Phab ntsa: Lub thickness yog xam.Lub thaiv phab ntsa yuav tsum ceev nrooj nrog mortar thiab yuav tsum tsis txhob muaj lub qhov ntsaws rov qab.Cast-in-chaw pob zeb phab ntsa yuav tsum tau lees tias yuav compact thiab zoo ib yam, thiab bulk ceev raws li tus tsim yuav tsum tau, tshwj xeeb tshaj yog tiv thaiv lub phenomenon ntawm "sinking mus rau hauv qab" ntawm cov khoom siv zawv zawg.Cov pob zeb loj loj yuav tsum tau ntxiv nrog qhov ntsuas kub kom tiv thaiv kom tsis txhob txhaws thiab tawg.Thaum siv cov hlau lead, cov hlau lead lossis Boron yas daim hlau, qhov dav ntawm lub puab tsaig yuav tsum yog> 10, thiab cov ntsia hlau kho cov phaj yuav tsum tau them nrog cov hlau lead.

3.Kev tiv thaiv qhov rooj: Lub thickness yog txiav txim los ntawm kev xam.Qhov dav ntawm lub qhov rooj thiab phab ntsa yuav tsum yog ≥ 100, thiab tsis muaj qhov sib txawv yuav tsum tau tso rau hauv nruab nrab ntawm ob lub qhov rooj.

4.Kev soj ntsuam qhov rai, hloov qhov rais: raws li qhov xav tau ntawm cov txheej txheem kev ua haujlwm los txiav txim siab.Qhov siab ntawm lub qhov rais sill yog txiav txim siab raws li qhov yuav tsum tau ua, qhov siab ntawm cov khoom siv hluav taws xob, kev taw qhia thiab cov xwm txheej tshwj xeeb ntawm cov neeg ua haujlwm sab nraum zoov.

5.Qhov cua nkag: txhua chav yuav tsum tau nruab nrog cov cuab yeej ua cua txias, thiab cov cua hloov pauv yuav tsum ua raws li GB8703-83 "txoj cai tiv thaiv hluav taws xob .Qhov chaw ua cua sov yuav tsum tau ceev faj tiv thaiv cov hluav taws xob tawm (tseem ceeb yuav tsum tau them rau neutron thiab accelerator chav).

6.Cov kav dej: Tsis txhob hla cov phab ntsa tiv thaiv lossis cov vaj huam sib luag.Thaum nws yuav tsum tau hla, yuav tsum tau siv cov polyline los hla, thiab yuav tsum tau muab kev txiav txim siab los tiv thaiv cov kab hluav taws xob los ntawm qhov tsis muaj zog.

7.Hluav taws xob: Qhov siab ntawm lub busbar sab hauv tsev yuav tsum yog ntau tshaj 3m los ntawm hauv av, thiab qhov siab-voltage ib feem ntawm cov cuab yeej yuav tsum tau grounded.Cov khoom siv hauv av yuav tsum tawm hauv cov yeeb nkab hauv av.Chav tsev hluav taws xob yuav tsum tau nruab nrog lub tswb nrov thiab koom nrog lub qhov rooj txuas cov cuab yeej.
