4. Zog. Cov no muaj xws nqa ntawm lub zog siv nyob rau hauv ntau lawm.
5. Material. Lawv ntau yam ntawm cov khoom thiab cov khoom ntawm zog, lub totality ntawm tej yam, uas muaj feem xyuam rau cov neeg nyob rau hauv cov txheej txheem.
6. Qhuav. Lawv yog ib tug txhais tau tias ntawm zog, los ntawm kev uas tus txiv neej ua rau tej khoom tsim cov khoom.

Logistical lub koom haum pab

Lawv tshwm sim tawm lub khoom ntawm zog, uas yog siv nyob rau hauv lub thib ob thiab thawj lawm. Lub ntsiab av uas txwv kom muab zais khoom pab - yog lawv cov keeb kwm. Piv txwv li, nyob rau hauv qhuav ntawm uas tsis yog-hlau siv, cov ntoo khoom. Tseeb tau thaum lub sij hawm ua rau tom hav zoov. Tsis-co yog tsim nyob rau hauv lub tshuaj industries. Lwm kauj uas cov classified cov ntaub ntawv thiab kev pab - uas yog lawv lub hom phiaj. Piv txwv li, raw cov ntaub ntawv yuav siv tau rau qhov siv thiab ua lub Cheebtsam, intermediates, khoom zaum kawg.

yam ntxwv ntawm

Muaj tej thaj chaw uas cov khoom thiab kev pab. Qhov no, nyob rau hauv particular, yam ntxwv xws li thermal conductivity, hluav taws xob conductivity, Thaum tshav kub kub muaj peev xwm, hardness, viscosity, thiab ceev. Lwm yam zog yog:

1. Daim ntawv no. Khoom tau nyob rau hauv daim ntawv ntawm slats, hexagonal, rods, beams thiab thiaj li nyob.
2. Qhov ntev. Khoom yuav ua tau nruab nrab, loj, me me luaj li cas, ntawm ntau ntau thiab tsawg.
3. Lub cev lub xeev - khoom, kua los yog roj.

enlarged division

Suam ntawm cov ntaub ntawv thiab kev pab, nyob ntawm seb daim ntawv thov ua cov nram no pawg:

1. Nyoo. Nws yog siv nyob rau hauv qhuav ntawm lub zog thiab lwm yam ntaub ntawv kev pab.
2. Semi-tiav lawm cov khoom. Lawv ua.
3. Ntaub ntawv. Lawv yog siv nyob rau hauv lub thib ob thiab thawj lawm.
4. Accessories. Lawv yuav siv los tsim cov khoom muag kawg.
5. Tiav lawm cov khoom. Nws muab cov kev xav tau ntawm cov neeg.

raw cov ntaub ntawv

Lawv nqa tawm lub logistics ntawm cov kev pab muab kev koom tes nyob rau hauv lub ntxiv hais plaub ntug. Cov raw khoom yog lub hauv paus ntawm cov khoom tiav los yog semi-tiav lawm cov khoom. Nws yog muab faib ua ob peb pawg. Ua ntej tso tawm muaj raw cov ntaub ntawv. Nws yog dag thiab mineral. Cov yav tas los xws li yas thiab cov khoom cua resins, rau daim tawv nqaij hloov, ntau yam detergents. Mineral zog pab muaj xws li uranium, peat, roj shale, thee, roj, nkev; tsuas thiab tshuaj - agronomic ore siv nyob rau hauv qhuav ntawm chiv, barite, uas los ntawm tus dawb xim, fluorspar, metallurgical thiab tshuaj industries, sulfur; kev - mica, graphite, diamonds; siv -. av nplaum, xuab zeb, pob zeb, thiab lwm yam Attendance tseem ceeb nyob rau hauv zus tau tej cov raw cov ntaub ntawv ua liaj ua teb muaj. Nws yog muab faib mus rau hauv cov kev pab:

1. Zaub. Cov no muaj xws kev thiab cov qoob loo.
2. Tsiaj txhu. Lawv yog cov mis nyuj, nqaij, wool, nyoos daim tawv nqaij, thiab cov qe.

Nyob rau hauv tas li ntawd, nyob rau hauv qhuav ntawm raw cov ntaub ntawv muab kev koom tes rau hauv lub nuv ntses thiab forestry industries.

ntaub ntawv

Lawv pab raws li lub hauv paus rau semi-tiav lawm cov khoom, Cheebtsam, khoom noj khoom thiab muaj lub hom phiaj. Ntaub ntawv raug muab faib ua lub ntsiab thiab tej koom haum. Cov yav tas muaj xws li cov neeg hom uas yog ncaj qha mus siv rau hauv lub tiav lawm cov khoom. Koom haum pab cov ntaub ntawv thiab kev pab - lawv yog cov khoom uas tsis yog ib feem ntawm lub tsim khoom, tab sis yog tsis muaj lawv nws yog tsis yooj yim sua los tsim. Cov pawg yog muab faib mus rau hauv chav kawm ntawv, hom, ib pawg, tej pab pawg, subclasses. Cov mob kev faib yog ua nyob rau hauv cov nram no pawg: non-co thiab co, gaseous, khoom, kua, tej.

semi-tiav lawm cov khoom

Lawv yog cov tseem ceeb heev rau zus tau tej cov ntaub ntawv thiab kev pab. Kev siv cov semi-tiav lawm cov khoom tau tso cai rau lub tuam txhab txuag rau lub tsev cov ntaub ntawv rau ntau lawm. Cov khoom muaj ua ntej raug hloov dua siab tshiab rau hauv tas cov khoom. Semi-tiav lawm cov khoom uas ntawm ob hom. Cov yav tas los xws li cov manufactured khoom nyob rau hauv lub enterprise, kis tau los ntawm ib tug lub tsev mus rau lwm lub. Qhov thib ob qeb ntawm semi-tiav lawm qhov chaw tau txais los ntawm lwm lub tuam txhab. Cov khoom yuav tsum tau muaj raws li ib tug ib-lub sij hawm ua, thiab multi-ua hauj lwm nyob rau hauv tshwj xeeb tswvyim.

accessories

Lawv yog cov npaj txhij rau siv cov ntsiab ntawm cov khoom muag kawg. Raws li by-khoom, lawv yog kis los ntawm ib tug enterprise mus rau lwm lub. Cheebtsam siv los sib sau ua ke lawm cov khoom, txij nkawm, ntim thiab li ntawd.

Deliverables

Nws muaj neeg khoom thiab muaj lub hom phiaj. Khoom muag intermediate los yog qhov xaus neeg siv. Cov neeg khoom yuav tau rov qab los yog ntev siv, txhua hnub los yog tshwj xeeb thov, pre-xaiv.

siv

Secondary khoom pab yog remnants ntawm semi-tiav lawm cov khoom, qhov chaw thiab lwm yam khoom tsim nyob rau hauv cov txheej txheem. Siv kiag los yog cov loses nws cov thawj zog. Cov theem nrab cov ntaub ntawv uas tej zaum yuav tsim thaum debiting qhov chaw dismantling cov rooj sib txoos, cov tshuab, aggregates thiab lwm yam khoom muaj nqis.

tsom xam ntawm

Ib tug ntawm cov tseem ceeb tshaj plaws qhov chaw ntawm kev tswj yog cov kev tswj ntawm cov ntaub ntawv thiab kev pab. Nyob rau tib lub sij hawm ib feem ntawm qhov kev ua hauj lwm pab tus tsom xam ntawm cov hauj lwm zoo ntawm tas cov cuab tam. Rau lwm yam kev mob ua sib npaug zos, lub ntau lawm ntim yuav tsum tau ntau dua, cov zoo muab qhauj nrog cov ntaub ntawv thiab kev pab. Lub enterprise yuav tsum tau ib lub koom haum tswj ntawm expenditure ntawm raw cov ntaub ntawv. Analysis ntawm lub logistical thiab nyiaj txiag tso cai rau kom paub tias cov tseem pheej chaw ntawm daim ntawv thov.
