Tus gal, qee zaum hu ua galileo tom qab Galileo Galilei, yog ib chav ntawm kev nrawm qee zaum siv hauv gravimetry. Lub gal yog txhais raws li 1 centimeter ib ob squared. Cov milligal thiab microgal yog feem ntau ib txhiab thiab ib lab ntawm ib gal. Tus gal tsis yog ib feem ntawm International System of Units.
Vim li cas gals thiaj hu ua Galileo?
Gal, chav tsev nrawm, muaj npe rau kev hwm ntawm Italian physicist thiab astronomer Galileo Galilei (1564–1642) thiab siv tshwj xeeb hauv kev ntsuas lub ntiajteb txawj nqus. Ib tus gal sib npaug sib npaug ntawm qhov kev hloov pauv ntawm ib centimeter (0.3937 nti) ib ob ib ob.
Microgal yog dab tsi?
The milligal (mGal) thiab microgal (µGal) yog feem ib txhiab thiab ib lab ntawm ib gal. … Lub gal yog ib chav derived, txhais nyob rau hauv cov nqe lus ntawm lub centimeter–gram-thib ob (CGS) lub hauv paus chav tsev ntawm qhov ntev, lub centimeter, thiab qhov thib ob, uas yog lub hauv paus chav tsev ntawm lub sij hawm nyob rau hauv ob qho tib si lub CGS thiab niaj hnub SI system.
1mgal yog dab tsi?
1 Mgal/d=1.121 txhiab acre-taw ib xyoos.
mGal gravity yog dab tsi?
i. Ib chav tsev ua haujlwm nyob rau hauv txoj kev gravitational ntawm geophysical prospecting. Nws yog kwv yees li ib lab ntawm qhov nruab nrab tus nqi ntawm qhov nrawm vim lub ntiajteb txawj nqus ntawm lub ntiaj teb nto; i.e., 1 milligal=1 cm/s2.
