Rau xam feem pua txoj kab nqes , faib qhov sib txawv ntawm qhov siab ntawm ob lub ntsiab lus los ntawm qhov kev ncua deb ntawm lawv, ces muab cov quotient los ntawm 100. Qhov sib txawv ntawm qhov siab ntawm cov ntsiab lus yog hu ua qhov nce. Qhov kev ncua deb ntawm cov ntsiab lus yog hu ua kev khiav. Yog li ntawd, feem pua txoj kab nqes sib npaug (nce / khiav) x 100.
Ua kom pom qhov no, koj yuav pom qhov piv ntawm txoj kab nqes li cas?
nqes hav feem pua yog xam nyob rau hauv ntau ib yam li cov gradient. Hloov qhov nce thiab khiav mus rau tib lub units thiab ces faib qhov nce los ntawm kev khiav. Muab tus lej no los ntawm 100 thiab koj muaj qhov feem pua txoj kab nqes . Piv txwv li, 3 "nce muab faib los ntawm 36" khiav =.
Tsis tas li ntawd, qib 10% yog dab tsi? Qhia qhov feem pua qib raws li ib feem ntawm 100. Piv txwv li, a 10 feem pua qib yog 10 / 100, thiab 25 feem pua qib yog 25/100.
Ib yam li ib tug yuav nug, koj ua li cas xam qhov poob piv?
PUAS = GRADIENT X DISTANCE Piv txwv li, xam tus poob nyob rau hauv ib tug 50 meter seem ntawm foul pipework yog hais tias tus gradient yuav tsum 1 nyob rau hauv 80. Ib tug gradient ntawm 1 nyob rau hauv 80 yog hloov dua siab tshiab rau ib tug xov tooj es tsis txhob ntawm ib tug gradient. piv.
Dab tsi yog 6% txoj kab nqes?
" 6 % qib" yog qhov txoj kab nqes ntawm txoj kev. Ib xees txhais tau tias ib puas ib puas 6 % qib yog 6 rau ib puas. Yog tias txoj kev nce toj ces qhov no txhais tau tias rau txhua 100 units koj taug kev kab rov tav koj nce koj qhov siab los ntawm 6 units.

Yuav ua li cas koj xam qab nthab kab noj hniav ratio?
Cov kauj ruam: Chav kab noj hniav piv = 2.9; qab nthab kab noj hniav piv = 0.0 (recessed teeb); pem teb kab noj hniav piv = 1.2 (piv txwv li rau 20 x 30 x 3 'qhov tob) Zoo qab nthab reflectance = . 80; zoo pem teb reflectance =
Dab tsi yog qhov txawv ntawm qhov ratio ntawm qhov ratio thiab tus nqi?
Ib qho piv txwv piv qhov loj ntawm ob qhov ntau. Thaum qhov ntau muaj qhov sib txawv, ces qhov piv yog hu ua tus nqi. Ib qho piv txwv yog ib nqe lus hais txog kev sib npaug ntawm ob qho piv txwv
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Cov nroj tsuag zoo li cas hauv hav zoov hav zoov hav zoov?
Canopy txheej Nws muaj feem ntau ntawm cov ntoo loj tshaj plaws, feem ntau 30-45 m hauv qhov siab. Siab, dav-leaved evergreen ntoo yog cov tseem ceeb nroj tsuag. Qhov chaw ntom ntom ntawm biodiversity yog pom nyob rau hauv hav zoov canopy, raws li nws feem ntau txhawb ib tug nplua nuj flora ntawm epiphytes, xws li orchids, bromeliads, mosses thiab lichens
Vim li cas cov dej thiaj li muaj qhov tsis zoo ntawm txoj kab nqes nqes?
Hauv cov duab kos duab, txoj kab nqes ntawm txoj kab nruab nrab ntawm cov khoom thiab cov kua dej yog qhov tsis zoo es tsis zoo. Yog vim li cas yog tias dej yog ib yam khoom txawv txawv nyob rau hauv uas nws lub xeev yog tsawg ntom dua li cov kua hauv lub xeev
