National Electrical Code (NEC), los yog NFPA 70, yog ib cheeb tsam uas tau txais kev pom zoo rau kev nyab xeeb ntawm kev teeb tsa hluav taws xob thiab khoom siv hauv Tebchaws Meskas. Nws yog ib feem ntawm National Fire Code series luam tawm los ntawm National Fire Protection Association ( NFPA ), lub koom haum kev lag luam ntiag tug.
Tsis tas li ntawd, thaum twg National Electrical Code pib?
Cov Code yog Ameslikas luam tawm xyoo 1897, thiab tau hloov kho ntau zaus --- feem ntau txhua peb xyoos --- txij li lub sijhawm ntawd. Cov Code yog luam tawm los ntawm National Lub Koom Haum Tiv Thaiv Hluav Taws Xob ("NFPA") ua ib feem ntawm nws National Hluav taws Cov lej series.
Tsis tas li ntawd, hluav taws xob Code yog dab tsi? Ib hluav taws xob code yog ib txheej txheej txheem rau kev tsim thiab installation ntawm hluav taws xob txuas hauv ib lub tsev. Lub hom phiaj ntawm a code yog muab cov qauv los xyuas kom meej hluav taws xob cov kab hluav taws xob uas muaj kev nyab xeeb rau tib neeg thiab khoom. Cov xaim zoo li no yog ua raws li cov qauv kev nyab xeeb nruj rau kev tsim thiab kev teeb tsa.
Tsuas yog li ntawd, qhov tseeb National Electrical Code yog dab tsi?
NEW NFPA 70®, National Electrical Code ® (NEC®), teem lub hauv paus rau hluav taws xob kev nyab xeeb.
Lub hom phiaj ntawm National Electrical Code yog dab tsi?
(A) Kev Tiv Thaiv Kev Nyab Xeeb. Cov lub hom phiaj ntawm NEC yog kom paub meej tias hluav taws xob cov tshuab tau nruab rau hauv ib qho kev tiv thaiv tib neeg thiab cov khoom ntiag tug los ntawm kev txo qis cov kev pheej hmoo cuam tshuam nrog kev siv hluav taws xob. (B) Kev tsim nyog. Cov Code muaj cov kev xav tau nec - sau ntawv rau kev nyab xeeb hluav taws xob kev teeb tsa.

Leej twg ntawm cov hauv qab no yog suav tias yog leej txiv ntawm kev ua haujlwm tshuaj?
Bernardino Ramazzini
Leej twg yog leej txiv ntawm epistemology niaj hnub?
Descartes' Epistemology. René Descartes (1596–1650) yog dav suav hais tias yog leej txiv ntawm kev xav niaj hnub no. Nws cov txiaj ntsig tseem ceeb txuas ntxiv mus rau lej thiab physics
Puas yog National Electrical Code yog txoj cai?
National Electrical Code (NEC) codifies yam tsawg kawg nkaus uas yuav tsum tau rau kev ruaj ntseg hluav taws xob installation nyob rau hauv ib tug, standardized qhov chaw. Txawm hais tias NEC tsis yog nws tus kheej raws li txoj cai lij choj hauv Teb Chaws Asmeskas, NEC feem ntau raug txib los ntawm lub xeev lossis txoj cai hauv zos. Qhov twg NEC tau txais, ib yam dab tsi tsawg dua yog txhaum cai
Yuav ua li cas koj pom qhov nruab nrab tshaj tawm ntawm qhov tshaj tawm vs lub sijhawm teeb?
Qhov chaw nyob hauv qab qhov nrawm / lub sijhawm nkhaus yog tag nrho cov kev hloov pauv. Yog tias koj faib qhov ntawd los ntawm kev hloov pauv hauv lub sijhawm, koj yuav tau txais qhov nruab nrab tshaj tawm. Velocity yog vector daim ntawv ntawm kev ceev. Yog tias qhov nrawm ib txwm tsis yog qhov tsis zoo, ces qhov nruab nrab tshaj tawm thiab qhov nruab nrab ceev yog tib yam
Leej twg yog leej niam leej txiv pab txhawb cytoplasmic qub txeeg qub teg?
Nyob rau hauv cov ntaub ntawv ntawm cytoplasmic qub txeeg qub tes, cov teebmeem ntawm niam txiv. Qhov no feem ntau yog vim muaj kev koom tes ntau dua ntawm cytoplasm rau zygote los ntawm niam txiv poj niam dua li txiv neej niam txiv. Feem ntau ovum txhawb ntau cytoplasm rau zygote dua cov phev
