Microcline (KAlSi3O8) yog triclinic qis-kub K-feldspar ruaj khov ntawm qhov kub qis dua 500 ° C. Nws yog feem ntau tsim los ntawm recrystallization los ntawm feldspar, thiab qee zaum los ntawm crystallization ncaj qha los ntawm magma thiab hydrothermal txheej txheem. Microcline feem ntau qhia albite thiab pericline twining.
Yog li ntawd, Microcline nyob qhov twg?
Microcline yog pom ntawm Baveno, Ltalis; Kragerø, Nor.; Madagascar; thiab, raws li amazonstone, hauv Urals, Russia, thiab Florissant, Colo., US Rau cov ncauj lus kom ntxaws txog lub cev, saib feldspar (rooj). Microcline yog daim ntawv ntawm cov poov tshuaj feldspar uas ruaj khov ntawm qhov kub qis tshaj plaws.
Ib yam li ntawd, qhov txawv ntawm microcline thiab orthoclase yog dab tsi? Lub xwb qhov sib txawv ntawm lawv yog lawv cov qauv siv lead ua. Microcline crystallizes hauv triclinic system, thiab Orthoclase thiab Sanidine crystallize hauv monoclinic system. Vim nws nyuaj heev rau paub qhov txawv ntawm Orthoclase , Sanidine, thiab Microcline , tej zaum lawv tsuas yog hu ua " Potassium Feldspar ".
Tsis tas li ntawd, koj yuav txheeb xyuas Microcline li cas?
Microcline tej zaum yuav ntshiab, dawb, daj-daj, cib-liab, los yog ntsuab; Nws yog feem ntau tus cwj pwm los ntawm tus ntoo khaub lig-hatch twinning uas tsim los ntawm kev hloov pauv ntawm monoclinic orthoclase rau hauv triclinic. microcline . Lub npe tshuaj lom neeg yog poov tshuaj txhuas silicate, thiab nws yog hu ua E tooj siv E555.
Qhov hardness ntawm Microcline yog dab tsi?
6 - 6.5

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Dab tsi yog qhov txawv ntawm kev xaiv khoom tsim thiab kev tsim noob caj noob ces?
Artificial xaiv xaiv rau cov yam ntxwv uas twb muaj nyob rau hauv ib hom, whereas genetic engineering tsim cov yam ntxwv tshiab. Hauv kev xaiv dag, cov kws tshawb fawb yug tsuas yog cov tib neeg uas xav tau qhov zoo. Los ntawm kev xaiv kev yug me nyuam, cov kws tshawb fawb muaj peev xwm hloov cov cwj pwm hauv cov neeg. Evolution tau tshwm sim
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Vim li cas thiaj nres thiab pib codons tsim nyog rau kev tsim cov protein?
Pib thiab nres codons yog ib qho tseem ceeb vim hais tias lawv qhia lub xov tooj ntawm tes machinery qhov twg yuav pib thiab xaus kev txhais lus, txheej txheem ntawm kev ua cov protein. Qhov pib codon cim qhov chaw ntawm qhov kev txhais lus rau hauv protein ntau pib. Qhov nres codon (los yog termination codon) cim lub vev xaib uas txhais lus xaus
