Cov qib ntawm qhov tseem ceeb ntawm kev txheeb cais feem ntau qhia tias yog p-tus nqi ntawm 0 thiab 1. Qhov me me p-tus nqi, qhov muaj zog pov thawj uas koj yuav tsum tsis lees paub qhov kev xav tsis tseeb. Tus nqi p-nqi tsawg dua 0.05 (feem ntau ≤ 0.05) yog qhov tseem ceeb.
Dab tsi yog qib tseem ceeb hauv kev txheeb cais?
theem tseem ceeb yog qhov tshwm sim ntawm kev tsis lees paub qhov kev xav tsis tseeb thaum nws muaj tseeb. … Piv txwv li, qhov tseem ceeb ntawm 0.05 qhia txog 5% kev pheej hmoo ntawm kev txiav txim siab tias qhov sib txawv tshwm sim thaum tsis muaj qhov sib txawv tiag tiag.
Lub ntsiab lus ntawm 0.05 theem ntawm qhov tseem ceeb yog dab tsi?
theem tseem ceeb, kuj txhais tau tias yog alpha lossis α, yog qhov tshwm sim ntawm kev tsis lees paub qhov kev xav tsis zoo thaum nws muaj tseeb. Piv txwv li, theem tseem ceeb ntawm 0.05 qhia a 5% kev pheej hmoo ntawm kev txiav txim siab tias qhov sib txawv tshwm sim thaum tsis muaj qhov sib txawv tiag tiag.
Koj txiav txim siab qhov tseem ceeb li cas?
txhawm rau nrhiav qhov tseem ceeb, rho tus lej qhia los ntawm ib qho. Piv txwv li, tus nqi ntawm ". 01" txhais tau tias muaj 99% (1-. 01=.
Koj xaiv qib tseem ceeb hauv kev txheeb cais li cas?
Koj tuaj yeem xaiv cov theem tseem ceeb ntawm tus nqi 0.05, thiab 0.01. Thaum p-tus nqi tsawg dua alpha lossis sib npaug 0.000, nws txhais tau tias qhov tseem ceeb, feem ntau yog thaum koj xaiv lwm qhov kev xav, txawm li cas los xij, thaum siv ANOVA tsom xam p-tus nqi yuav tsum ntau dua Alpha.

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 .
Nyob rau hauv lub ntsuas kub ntsuas ntsuas los ntawm?
Thermography ntsuas qhov kub ntawm qhov chaw los ntawm kev siv infrared video thiab tseem lub koob yees duabCov cuab yeej no pom lub teeb uas nyob hauv qhov kub thiab txias. Cov duab ntawm daim vis dis aus lossis zaj duab xis kaw qhov kub hloov pauv ntawm lub tsev ntawm daim tawv nqaij, xws li dawb rau thaj chaw sov mus rau xim dub rau qhov chaw txias dua .
Tus kws ntsuas ntsuas ntsuas qib 1 yog dab tsi?
Level I cov kws ntsuas ntsuas ntsuas feem ntau ua raws cov txheej txheem sau ntawv los ntsuas cov cuab yeej tshwj xeeb hauv lawv qhov chawLawv tuaj yeem ua haujlwm lawv lub koob yees duab infrared thiab software thiab txheeb xyuas thiab ntsuas thermal anomalies raws li thermal cov qauv, kev sib piv nrog cov cuab yeej zoo sib xws, thiab lawv cov kev paub dhau los .
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.
