Tsis ntev los no, kev txaus siab rau cov tshuaj sulfur hexafluoride tau loj hlob. Qhov no tau txhawb nqa los ntawm cov kev lom zem hauv TV, cov uas nto moo tshaj plaws yog Good Jokes thiab MythBusters. Muaj coob tus neeg tshwj xeeb tshaj yog txaus siab nyob rau hauv lub fact tias nrog kev pab los ntawm cov tshuaj no koj muaj peev xwm hloov lub timbre ntawm lub suab - nws yog heev tsawg. Cov neeg txiav txim siab tias qhov no yog lub tswv yim zoo rau ob tog, kev sib tw thiab lwm yam kev ua si lom zem. Yog tias muaj kev thov, yuav muaj cov kev pabcuam: nws tsis yog qhov nyuaj rau nrhiav kev tshaj tawm rau kev muag sulfur hexafluoride hauv Is Taws Nem. Tab sis, ua ntej koj maj mus yuav cov khoom no, nws yuav muaj txiaj ntsig los xyuas seb nws yog dab tsi thiab nws muaj kev nyab xeeb npaum li cas rau tib neeg.
Sulfur hexafluoride, tseem hu ua SF6, los yog sulfur hexafluoride, los yog sulfur hexafluoride, yog ib qho tshuaj inorganic. Nws tau paub ntau tshaj 100 xyoo thiab tau ua tiav los ntawm tus txiv neej rau nws lub hom phiaj rau tib tus nqi. Chemical zog: inert, non-toxic, hnyav roj (5 zaug hnyav dua huab cua). Cov khoom yog tsis muaj xim kiag li, muaj hluav taws xob siab zog thiab siab tawg voltage. Muaj ob txoj hauv kev ntawm nws txoj kev tsim - los ntawm qhov yooj yimtshuaj thiab thaum lub sij hawm decomposition ntawm complex sulfur fluorides. Vim nws lub cev thiab tshuaj lom neeg, nws yog siv los ua dielectric hauv kev lag luam hluav taws xob, ua cov txheej txheem nruab nrab hauv kev lag luam hluav taws xob, thiab ua ib qho nruab nrab inert rau tsim cov alloys hauv metallurgy. Tsis ntev los no, SF6 (luv luv rau "hluav taws xob roj") tau siv los tua hluav taws ua tus neeg tua hluav taws. Cov no yog cov kev siv tseem ceeb ntawm sulfur hexafluoride.
Tab sis kev lom zem TV tau nthuav dav ntawm cov khoom no thiab ua rau nws nrov. Yog vim li cas rau qhov no yog nws lub peev xwm los hloov tib neeg lub suab: yog tias koj nqus tau cov sulfur hexafluoride, lub suab yuav ua tsis taus pa,
tsis ncaj ncees lawm. Kuv xav tias yog vim li cas qhov no tshwm sim? Nws yog feem ntau tuaj yeem hla cov kev xav tias SF6 ua rau lub suab nrov, ua rau lawv lub sijhawm luv luv thiab yog li "tso" lub suab. Nws tsis zoo li ntawd kiag li. Qhov tseeb yog tias cov suab paj nruag lawv tus kheej tsis tsim lub suab nrov. Tib neeg hais lus apparatus, ntxiv rau ligaments, kuj muaj xws li resonators. Ib tug ntawm cov resonators yog lub pharynx. Lub timbre ntawm lub suab yog cuam tshuam, ua ntej ntawm tag nrho cov, los ntawm ib puag ncig ntawm no resonator. Yog hais tias qhov nruab nrab no yog huab cua, ces peb hnov ib tug zoo tib yam, paub lub suab. Tab sis nws tsim nyog hloov ib puag ncig, thiab peb yuav hnov ib lub suab sib txawv, tag nrho cov neeg txawv teb chaws. Qhov no tau piav qhia los ntawm cov hauv paus ntsiab lus hauv qab no: qhov sib zog ntawm cov roj thiab qhov nrawm ntawm nws cov molecules, lub suab yuav siab dua. Thiab vice versa: qhov hnyav dua cov pa, qhov qeeb qeeb ntawm cov molecules, qhov qis ntawm cov timbre. Helium yog lighter tshaj huab cua, yog li thaum koj nqus tau cov pa, koj lub suab yuavsqueaky, nyias heev. Sulfur hexafluoride, raws li twb tau hais lawm, yog 5 zaug hnyav dua, thiab yog tias koj nqus tau nws, lub suab yuav ntxhib thiab qis. Ntawd yog tag nrho: xws li cov txiaj ntsig lom zem ntawm SF6 roj tuaj yeem piav qhia los ntawm kev hloov pauv luv luv hauv ib puag ncig resonator. Kev nqus ntawm cov khoom no tsis muaj peev xwm ua rau lub cev puas tsuaj yog tias nws tsis muaj cov impurities txawv teb chaws.
Yog tias koj xav yuav sulfur hexafluoride, tus nqi yuav tsum tsis txhob txiav txim siab rau koj. Tsis muaj leej twg hais tias qhov no tseem ceeb, tab sis kev noj qab haus huv yog kim dua. Yog li ntawd, thaum yuav SF6, nug tus neeg muag khoom yog tias nws yog "ntshiab" hexafluoride, seb nws puas muaj lwm yam ntxiv. Qhov no yuav tiv thaiv koj thiab koj cov qhua, uas koj yuav lom zem nrog SF6 roj, los ntawm kev xav tsis thoob thiab tsis txaus siab.
