Yog nws ua tau kom lub teeb qhov chaw tshuaj nrog lawv ob txhais tes?

Oh, cov neeg uas lawv Jedi lightsabers, zoo siab heev lub minds ntawm lab, nws tsis yog peb. Nyob rau hauv cov yeeb yam, nws ntsia ntau tshaj impressive, thiab 10 xyoo dhau los dawb lias glow sticks, coj Suav dev mub ciaj uas muag thiab tsuas heev vaguely reminiscent ntawm ib qho kev ntsuas xa mus rau knights, tsim ib tug furore. Tswv yim neeg, ib yam li fishermen thiab soj ntsuam ntawm, tam sim ntawd menyuam cov teeb tsis tau tsuas yog raws li ib tug txhais tau tias ntawm kev tsim ib tug haum ncig, tab sis kuj raws li ib tug lwm txoj rau lub teeb qhov chaw. Cov tshuaj txoj kev ua pom lub teeb muaj ib tug heev tsawg emissivity. Nyob rau hauv tas li ntawd, nws yuav tsum muaj ntaub ntawv nyob rau hauv tej yam kev mob nyob qhov twg lwm yam teeb yuav tsis ua hauj lwm. Nug minds experimenters tam sim ntawd xav yuav ua li cas nyuaj heev rau tsim xws li ib tug glow lo lawv ob txhais tes.

ntau ntau yam Nws

Nws - tshuaj qhov twg los ntawm prefabricated lub teeb yuav pom tsis tau xwb nyob rau hauv lub khw ntawm cov khoom ua si thiab decorations. Model ntau thiab, ntawm chav kawm, muaj zog tshaj nyob rau hauv lub twj tshwj xeeb ntawm rescuers, divers, speleologists thiab lwm cov tub txawg txuam nrog txawv txawv ua hauj lwm tej yam kev mob. Cov khoom xyaw muab kev koom tes nyob rau hauv cov tshuaj tiv thaiv yog heev yooj yim mus nkag rau lub sau, thiab ib co nqi ib tug loj npaum li cas. Ib txhia ntawm cov tshuaj yuav ua tau tsis zoo, thiab nws xav kom tsis txhob muaj nyob rau hauv lub handicraft kev lag luam. Nyob rau hauv kev, experimentally pom tias ob peb txoj kev, xws li hai.

Cov ua hauj lwm ntawm ID

не работает. Peb khuv xim peb yuav hais tias ib tug zoo-paub ua kom yuam kev ntawm Roob Lwg haus tsis ua hauj lwm. Yuav kom ua tau kiag li yog, nws tsis ua hauj lwm nrog cov khoom xyaw uas siv nyob rau hauv lub zoo-paub xyaum ua tej yam, vim hais tias cov teeb nyob rau hauv ib lub hnab yas raj mis nyob rau hauv lub hauv paus ntawm no haus dej yog heev realizable. Hais txog qhov no tom qab.

Qhov yooj yim luminaire acetone

Catalytic oxidation ntawm acetone yuav ntshai raws li lub teeb qhov chaw, tshuaj paus ntsiab lus uas yog txawv los ntawm cov pa combustion. Qhov txawv tsuas yog qhov uas tsis qhib nplaim taws. Luv luv, nyob rau hauv ib tug pob tshab ntim yog poured me me ntawm acetone. Nws yog tsuas ib qho tseem ceeb ua rau cov tsim thiab txuam nrog ntawm roj vapors thiab lawv nws nrog cua oxygen. Tooj liab hlau yog dov ib daim txiag caij nplooj ntoos hlav los yog lwm yam txhais tau tias mus rau lub coils twb los ze zog mus rau txhua lwm yam los mus tsim ib tug loj cheeb tsam ntawm cov tshuaj tiv thaiv mus rau ib tug tsawg raws li. Qhov no kawg ntawm cov hlau yog rhuab mus liab thiab nws txo qis rau hauv lub thawv nrog cov officers ntawm acetone, thiab cov acetone rau cov tooj liab nto reacts nrog cov pa, tso ntxiv thaum tshav kub kub. Cov uas ua lub zog koom tes rau cov tshuaj tiv thaiv kub thiab ntxiv heats cov hlau kom txog thaum lub luminescence lub xeev. Xws li ib tug teeb tsim npaum li cas thaum tshav kub kub, thiab lub teeb yog tau los ntawm lub cua sov ntawm tooj liab, tab sis txawv txawv thiab tshuaj cov pej xeem yog, yog li peb yuav tsis quav ntsej nws.

Tshuaj luminol oxidation los ntawm lub teeb

Nrhiav txoj cai cov khoom xyaw thiab ib tug ua hauj lwm daim ntawv qhia thaum kawg coj mus rau ib tug fee tshwm sim. Luminol yog siv nyob rau hauv forensic tshuaj mus ntes cov ntshav residues: hlau ions nyob rau hauv cov ntshav ua raws li ib lub hauv paus thiab oxidizes luminol tso tawm lub teeb. Nrhiav no yam khoom uas yuav tsis yooj yim, cov tshuaj "Galavit" muaj cov sodium ntsev ntawm luminol nyob rau hauv txaus ntau rau ib tug xov tooj ntawm thwmsim nrog rau qhov siv ntawm cov tshuaj siv raws li lub teeb qhov chaw. Tshuaj nam ntawm tag nrho cov txiav txim txhais tau tias lub peev xwm rau lub teeb yuav tsum tsis txhob siv nyob rau hauv lub tsev kom tsis txhob muaj lom los yog daim tawv nqaij puas txhoj puab heev tshuaj. Ceev faj thaum ua kev ntsuam xyuas, hnav tiv thaiv cov hnab looj tes, tsom iav thiab qhov ncauj yog tias tsim nyog.

Qhuav ntawm tshuaj teeb qhov chaw (Nws) nyob rau hauv aqueous lub ntsiab

Yog li ntawd peb txiav txim siab nyob rau hauv ib tug yooj yim neeg sawv cev, koj yuav tsum xav txog qhov zoo tagnrho tej yam kev mob ntawm cov tshuaj tiv thaiv. Cov kuab uas yuav tsum tau raws li cov kua nruab nrab. Nyob rau hauv nws lub luag hauj lwm yuav ua tsis tu ncua cov dej los ntawm tus kais, tab sis luminol yog suab insoluble nyob rau hauv nws. Yuav kom cov tshuaj tiv thaiv mus uniformly, "Galavit" yuav muaj finely zom thiab npaj ib ncua kev kawm, thiab yuav tsum tau ib lub hauv paus nrog ib tug loj tso tawm ntawm cov hlau los yog tooj liab ions nyob rau hauv cov tshuaj. Tooj sulfate los yog tooj liab sulfate, raws li nws yog hu ua, yog ib qho zoo heev amplifier cov tshuaj tiv thaiv nyob rau hauv cov dej. Yuav kom ua tau ib lub alkaline puag ncig yuav tsum tau ammonia, dua li sodium los yog poov tshuaj hydroxide. Nws ua hauj lwm pab raws li ib tug hydrogen peroxide oxidizer, cov nram qab proportions:

• 100 ml ntawm cov dej tov nrog 2-3 rastortymi tshuaj "Galavita";

• ntxiv 50 ml ntawm hydrogen peroxide;

• 5.3 g ntawm tooj liab sulfate los yog cov ntshav liab ntsev;

• 30 ml ntawm cov kua ammonia, los yog 15 ml ntawm Koh los yog NaOH tshuaj.

Lub glow yuav tshwm sim yuav luag tam sim ntawd tom qab nws, thiab yuav mus ntxiv rau ob peb teev. Mus ntxiv qhov kev txiav txim tsim nyog mus ntxiv grated 'Galavit "thiab hydrogen peroxide nyob rau hauv cov tshuaj thiab maj mam muab shaken.

Sim kawm nrog "Dimexidum"

Sim kawm nrog dej, muab ib tug tshwm sim weaker tshaj yuav tsum, vim cov neeg pluag solubility ntawm luminol, yuav tsum tau saib rau ib tug zoo dua ib puag ncig. Dimethyl sulfoxide copes nrog cov hauj lwm ntawm dissolving lub reagents, koj muaj peev xwm yuav nws nyob rau hauv pharmacies nyob rau hauv lub npe "Dimexidum". Siv ceev faj thaum ua hauj lwm nrog cov tshuaj no vim hais tias ntawm nws cov tob tob hwj chim ua rau cov tawv nqaij permeable mus rau ntau yam av, uas nyob rau hauv ib txwm tej yam kev mob ntse tsis txaus los ntawm peb tej yam ntuj tso kev tiv thaiv txheej. Cov tshuaj tiv thaiv, tus catalyst yuav tau muab tshem tawm, vim hais tias nrog vitriol thiab cov ntshav ntsev cov tshuaj tiv thaiv hais dhau sai heev thiab luv luv. Empirically xam nyob rau hauv cov nram no proportions:

• в сухом виде (следует полностью отказаться от воды для чистоты эксперимента); 20 g ntawm Koh los yog NaOH nyob rau hauv ib tug qhuav daim ntawv (yuav tsum tau kiag li tso tseg dej xyaum ua tej yam kev coj dawb huv);

• 100 ml "Dimexidum" siab yaj hydroxide yog tsis tsim nyog, rau ntawm qhov chaw ntawm nws cov tshuaj tiv thaiv thiab precipitate pib;

• 1 ntsiav tshuaj "Galavita" rastortaya rau hauv hmoov yaj sai.

Los ntawm txoj kev, cov tshuaj no yuav tsum npaj kom txhij nyob rau hauv ua ntej thiab sau luminol, yog tias tsim nyog, lub tseem ceeb tshaj plaws - mus kom kev ntseeg thiab kev muaj peev xwm ceev ceev. Nws yog ib nqi rau ceeb toom hais tias ib tug sib tov ntawm caustic alkalis thiab "Dimexidum" corrodes yas hwj rau 3-4 hnub, ces nws yog advisable rau tsuas yog ib-off thiab luv luv siv cov ntim rau npaj tshuaj teeb qhov chaw.

lwm yam kev xaiv

Muaj ntau ntau cov zaub mov txawv rau cov creation ntawm ib tug dej xws li ib tug tshuaj teeb qhov chaw, muaj cov kev xaiv ntawm ntxuav kua raws li ib tug nruab nrab, thiab txawm tib neeg cov ntshav raws li ib lub hauv paus, tab sis feem ntau ntawm lawv yog cov tsuas xaiv nyob rau peb cov zaub mov txawv. Koj koj tus kheej muaj peev xwm xaiv lawv tus kheej cov neeg ua hauj thiab lawv kev txheeb ze rau kev, xws li dej qab zib Roob Lwg.
