Cov sib txawv P 1 P_1 P1?P, pib subscript, 1, kawg subscript, v 1 v_1 v1?v, pib subscript, 1, kawg subscript, h 1 h_1 h1?h, pib subscript, 1, kawg subscript xa mus rau lub siab, ceev , thiab qhov siab ntawm lub kua dej ntawm point 1, where the sib txawv P 2 P_2 P2?P, pib subscript, 2, kawg subscript, v 2 v_2 v2?v, pib
Kuj nug, qhov kev sib npaug Bernoulli ntsuas li cas?
Cov Bernoulli Equation tuaj yeem suav hais tias yog ib nqe lus ntawm kev txuag hluav taws xob txoj cai tsim nyog rau cov dej ntws. Tus cwj pwm zoo uas feem ntau sau nrog lo lus " Bernoulli effect" yog qhov txo qis ntawm cov kua dej hauv cov cheeb tsam uas qhov kev nrawm nrawm nce ntxiv.
Ib tug kuj yuav nug, Bernoulli lub ntsiab lus yooj yim yog dab tsi? Bernoulli txoj cai yog ib lub tswv yim ntawm cov dej dynamics. Nws hais tias raws li qhov ceev ntawm cov kua nce, lub siab txo. Thov nco ntsoov tias qhov no yog hais txog kev hloov pauv hauv kev nrawm thiab siab raws li ib txoj hauv kev ntws thiab tsis siv rau ob qhov sib txawv ntawm qhov sib txawv.
Yog li ntawd, peb nqe lus hauv Bernoulli qhov sib npaug sawv cev li cas?
Txhua lub sij hawm sawv cev lub zog ib unit ntim ntawm cov kua. Thawj lub sij hawm sawv cev lub zog siab, qhov thib ob sawv cev lub zog kinetic, thiab peb sawv cev gravitational muaj peev xwm zog.
Qhov kev thov ntawm Bernoulli qhov sib npaug yog dab tsi?
Ib qho piv txwv ntawm daim ntawv thov ntawm Bernoulli's Equation nyob rau hauv ib tug tsiv siv ncej yog nrhiav lub siab ntawm lub tis ntawm ib tug dav hlau ya nrog tej yam ceev. Hauv qhov no, lub kev sib npaug yog siv ntawm qee qhov taw tes ntawm lub tis thiab ib qho taw tes hauv huab cua dawb. Cov no muaj tsawg kev siv ntawm Bernoulli's Equation.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
