Piv txwv ntawm Tertiary Sources: Dictionaries/encyclopedias (tej zaum kuj yog secondary), almanacs, factbooks, Wikipedia, bibliographies (tej zaum kuj yog theem nrab), phau ntawv qhia, phau ntawv qhia, phau ntawv, phau ntawv qhia, thiab phau ntawv kawm (tej zaum yuav yog qhov thib ob), indexing thiab abstracting qhov chaw.
Puas yog qhov ntsuas thawj lossis qhov thib ob?
Piv txwv ntawm qhov chaw thib ob suav nrog phau ntawv txhais lus, phau ntawv txhais lus, phau ntawv kawm, thiab phau ntawv thiab cov ntawv uas txhais lossis tshuaj xyuas cov haujlwm tshawb fawb. Cov peev txheej no teev, sau ua ke, zom, lossis ntsuas qhov tseem ceeb lossis qhov chaw thib ob. Piv txwv ntawm cov hauv paus tsev kawm ntawv qib siab suav nrog indexes, phau ntawv qhia, digests, thiab almanacs.
Puas yog qhov ntsuas qhov nruab nrab?
Indexes, bibliographies, concordances, thiab databases yuav tsis muab ntau cov ntaub ntawv, tab sis raws li ib tug tag nrho ntawm cov thawj thiab thib ob qhov chaw, lawv yog feem ntau suav hais tias yog tertiary sources.
Dab tsi yog qhov ntsuas qhov ntsuas?
Indexes feem ntau yog pom raws li ib lossis ntau tus neeg ntim ntawm qhov kawg ntawm cov txheej(xws li nrog cov duab CJS indexes) lossis hauv qab ntawm phau ntawv. Koj tuaj yeem nkag mus rau qhov ntsuas ntsuas thaum siv cov khoom siv hluav taws xob. Qhov no tej zaum yuav yog ib qho kev sib txuas kiag li ntawm qhov txuas. Txheeb xyuas cov ntsiab lus ntsuas.
Dab tsi los ntawm qhov chaw thib ob?
Rau qhov kev tshawb fawb keeb kwm, cov ntaub ntawv thib ob feem ntau yog cov ntawv kawm thiab cov ntawv Ib qhov chaw thib ob txhais thiab txheeb xyuas cov hauv paus ntsiab lus. Cov peev txheej no yog ib lossis ntau kauj ruam tshem tawm ntawm qhov kev tshwm sim. Qhov chaw thib ob yuav muaj cov duab, cov lus hais los yog cov duab ntawm cov hauv paus ntsiab lus.

A throttle position sensor (TPS) yog ib qho sensor siv los saib xyuas huab cua nkag ntawm lub cav. Lub sensor yog feem ntau nyob ntawm tus npauj npaim ntxaiv / ncej, kom nws tuaj yeem saib xyuas txoj haujlwm ntawm lub throttle . Lub throttle txoj hauj lwm sensor zoo li cas?
Los ntawm qhov ntsuas qhov ntsuas qhov ntsuas?
Lub throttle txoj hauj lwm sensor (TPS) yog qhov tseem ceeb ntawm koj lub tsheb kev tswj hwm roj, ua haujlwm kom ntseeg tau tias qhov sib xyaw ntawm huab cua thiab roj tau xa mus rau koj lub cav. Lub sensor no ua haujlwm nyob rau hauv tandem nrog lwm tus sensors kom optimize acceleration, cruising ceev thiab roj economy .
Ntsuas qhov ntsuas qhov ntsuas li cas?
Tus odometer yog ib qho cuab yeej siv rau ntsuas qhov kev ncua deb ntawm lub tsheb. Lub odometer feem ntau yog nyob rau hauv lub tsheb lub dashboard. Lo lus "odometer" yog muab los ntawm ob lo lus Greek lub ntsiab lus thiab kev ntsuas .
Yuav ntsuas ntsuas ntsuas ntsuas li cas?
Ib lub ntsuas hluav taws xob muaj peev xwm ntsuas tus nqi ntawm cov khoom tawg tag nrho (TDS) hauv cov tshuaj, hauv cov khoom ntawm ib lab (ppm) lossis milligrams ib liter. Tus qauv kev sib raug zoo ntawm TDS kev ntsuas ntawm kev daws teeb meem thiab kev ntsuas kev ntsuas yog:
Dab tsi yog qhov ntsuas qhov ntsuas qhov ntsuas?
Cov qhab nia Ballard yog feem ntau siv los txiav txim siab lub hnub nyoog gestational Nov yog nws ua haujlwm li cas: Cov qhab nia tau muab rau 6 lub cev thiab 6 paj hlwb thiab cov leeg nqaij (neuromuscular) cov cim ntawm kev loj hlob. Cov qhab nia rau txhua tus tuaj yeem nyob ntawm -1 txog 5.
