Indium yog ib qho ntawm cov minerals tsawg tshaj plaws hauv ntiaj teb. Nws tau pom tias tsis sib xyaw hauv cov xwm txheej, tab sis feem ntau nws pom muaj cuam tshuam nrog zinc cov zaub mov thiab hlau, txhuas thiab tooj liab ore. Nws yog kev lag luam tsim tawm los ntawm cov khoom lag luam ntawm kev kho kom zoo zinc.

Ib yam li ib tug yuav nug, dab tsi yog qhov tseem ceeb ntawm kev siv indium?

Indium yog siv los dope germanium los ua transistors. Nws kuj tseem siv los ua lwm yam khoom siv hluav taws xob xws li rectifiers, thermistors thiab photoconductors. Is Nrias teb tuaj yeem siv los ua cov iav uas muaj qhov cuam tshuam zoo li cov iav nyiaj tab sis tsis txhob tarnish sai li sai tau. Is Nrias teb Nws kuj yog siv los ua cov hlau tsis tshua muaj melting.

Ib yam nkaus, lub npe indium los qhov twg los? Lawv npe lub ntsiab indium , los ntawm cov xim indigo pom hauv nws cov spectrum, tom qab Latin indicum, lub ntsiab lus 'ntawm Is Nrias teb'. Richter tau mus cais cov hlau hauv xyoo 1864.

Ntawm no, qhov twg tuaj yeem nrhiav tau Indium?

Qhov chaw & ntau Is Nrias teb tsawg tsawg pom uncombined nyob rau hauv qhov thiab yog feem ntau pom hauv zinc, hlau, txhuas thiab tooj liab ore. Nws yog 61st feem ntau cov khoom nyob rau hauv lub ntiaj teb crust thiab nyob ib ncig ntawm peb zaug ntau tshaj nyiaj los yog mercury, raws li US Geological Survey (USGS).

Puas yog indium ua kua lossis roj?

Lub npe originates los ntawm cov xim Indigo nyob rau hauv nws atomic spectrum. Cov ntsiab lus tuaj yeem raug cais raws li lawv lub cev lub xeev (States of Matter) e.g. roj, khoom lossis kua. Cov khoom no yog ib qho khoom. Indium tau muab cais ua ntu 'Lwm Yam Hlau' uas tuaj yeem nyob hauv pab pawg 13, 14, thiab 15 ntawm Cov Sijhawm Sijhawm.

Dab tsi yog lub npe ntawm cov khoom tsim uas yog qhov tseem ceeb rau kev pib tsim cov ntshav khov?

Thrombocytes (platelets) Megakaryocytes tsim los ntawm hemocytoblasts hauv cov pob txha liab. Thrombocytes dhau los ua nplaum thiab sib sau ua ke los ua cov platelet ntsaws uas kaw qhov tawg thiab kua muag hauv cov hlab ntshav. Lawv kuj pib tsim cov ntshav txhaws

Nyob rau theem dab tsi ntawm kev tsim cov kab mob fungal yog diploid cells tsim?

Hauv lub neej voj voog ntawm kev sib deev kis tus kab mob hu ua fungus, theem haploid hloov nrog qib diploid. The haploid theem xaus nrog nuclear fusion, thiab theem diploid pib nrog kev tsim zygote (diploid cell ua los ntawm fusion ntawm ob haploid cells)

Cov kab mob hauv qhov ncauj dab tsi metabolize sucrose tsim cov nplaum glucans thiab tsim cov quav hniav?

GTF yog qhov tseem ceeb enzyme uas catalyzes sucrose rau nplaum glucans thiab pab txhawb kev tsim cov hniav plaque nyob rau hauv uas lub tsub zuj zuj ntawm metabolic acids uas ua los ntawm cov kab mob colonies ua rau lub zos demineralization ntawm cov enamel nto (Loesche, 1986)

Qhov feem pua ntawm cov ntshav tau tsim los ntawm cov khoom tsim?

Cov qe ntshav no (uas tseem hu ua corpuscles lossis 'tsim cov ntsiab lus') suav nrog erythrocytes (cov qe ntshav liab, RBCs), leukocytes (cov qe ntshav dawb), thiab thrombocytes (platelets). Los ntawm qhov ntim, cov qe ntshav liab muaj li ntawm 45% ntawm cov ntshav tag nrho, cov ntshav plasma txog 54.3%, thiab cov qe dawb txog 0.7%
