Nnyocha Mgbe Niile
Nnyocha Ọdịdị: Kwa ọnwa, a na-enyochakarị maka mmebi nke oyi akwa nchebe, mgbanwe nke etiti, na ire ere igbe osisi.
Nnwale ọzọ nke ziri ezi: Kwa ọnwa atọ, site na iji laser interferometer iji lelee larịị (≤ 0.02mm/m) na vetikal (≤ 0.03mm/m).
Usoro Mberede
Mmebi oyi akwa nchekwa: Jiri teepu anti-static mechie ozugbo (≥ 3N/cm adhesion) ma jiri ihe nkiri ọhụrụ dochie ya n'ime awa iri abụọ na anọ.
Ọ bụrụ na iru mmiri gafere ọkọlọtọ: Mee ka usoro ọgwụgwọ ụfọdụ rụọ ọrụ ma dekọọ data. Nchekwa nwere ike ịmaliteghachi naanị mgbe iru mmiri laghachiri n'ókè kwesịrị ekwesị.
V. Ndụmọdụ maka Nchekwa Ogologo Oge
A na-etinye mbadamba ihe mgbochi uzuoku (VCI) n'ime igbe osisi ahụ iji wepụta ihe ndị na-egbochi nchara ma chịkwaa ire ere nke etiti ígwè ahụ.
Nlekota Anya nke Ọma: Tinye ihe mmetụta okpomọkụ na iru mmiri (izi ezi ±0.5°C, ±3%RH) na ikpo okwu IoT maka nlekota anya n'ime awa iri abụọ na anọ n'ụbọchị asaa n'izu.
Nkwakọ ngwaahịa a na-emegharị emegharị: Jiri etiti alloy aluminom a na-apịachi apịachi ya na ihe mkpuchi ihe na-agbanwe agbanwe, na-ebelata ọnụ ahịa nkwakọ ngwaahịa site na ihe karịrị 30%.
Site na nhọrọ ihe, nkwakọ ngwaahịa a haziri ahazi, nchekwa nke ọma, na njikwa ike, ntọala granite na-ejigide arụmọrụ kwụsiri ike n'oge nchekwa, na-eme ka ọnụego mmebi njem dị n'okpuru 0.5%, ma na-agbatị oge nchekwa ahụ ruo ihe karịrị afọ 5.
