Nkauj thov ua suab paj nruag

Hauv kev kho dua tshiab ntawm Golden Hall nyob Vienna, Acoustic Master siv cov teebmeem suab nrov hauv cov suab nrov hauv lub xyoo 19th. 312 conical micropores yog faib rau ib square meter, thiab theem nrab zaus reverberation lub sij hawm ntawm 24 {} hz yog tswj ntawm 1.8 vib nas this 0.05. Laser cuam tshuam ntsuas pom tias lub zog yoj hluav taws xob muaj zog yog 43% thiab kev sib cav sib ceg tau zoo rau 96 cov ntsiab lus. Cov ua yeeb yam xav tsis thoob ntawm lub suab tsis pom kev sib txuas-ua kom tuab ntawm 5 hli txog 22 hli, sib sau ib qho kev qhia dav dav. Thaum tu, nitrogen yog siv los tshem cov plua plav kom tsis txhob muaj fiber ntau cov chaw nyob, uas keeb kwm daws teeb meem ntawm cov khoom siv suab. Acoustics lub voj voog tau ntsuas qhov no yog "qhov kev sib tw sib luag tshaj plaws ntawm cov khoom lag luam sab nrauv" thiab yeej cov qauv qauv qauv qauv.

Yam ruaj khov

Tuam Tshoj Antarctic Kunlun Chaw Nres Tsheb Tam Sim No tau xya-txheej Composite PVC Orgulation Board kom muaj qhov kub tsis tu ncua ntawm kev kub ntxhov ntawm {2}} degree. Cov ntsiab lus thev naus laus zis nyob rau hauv kev sib xyaw airgel interlayer thiab lub tshuab taws xob aluminium conductivity yog tsawg li}. {14}} 08 w / (mk). Cov phaj tau kos nrog cov tshuab hluav taws xob siv kho qhov muag tau los soj ntsuam kev ntxhov siab thiab deformation ntawm 2000㎡ qab nthab nyob rau hauv lub sijhawm 2000㎡ Cov pab pawg neeg nrhiav tau pom tias cov tshuaj fluorescent tau txhim kho cov khoom siv txij nkawm, thiab kev poob nthav ntawm Aurora Rynamic projection ua haujlwm. Tsawg-kub kho cov nplaum tau siv thaum lub sijhawm teeb tsa, thiab lub zog ua zog tseem tau mus txog 18mpa ntawm {10}} degree. Lub Norwegian Polar Tshawb Fawb Lub Tshuab tau yuav siv cov thev naus laus zis no, thiab tshwj xeeb tshaj yog cov tshuaj tiv thaiv kab mob los ntawm 10 meters, tawm tsuas yog 0.3 hli.

Kev Tiv Thaiv

Hauv Okinawa, Nyij Pooj, cua ua pov thawj lub vov vov tsev tau ua nrog corrugated pvc nplooj ntawv, uas ua tiav {1}} qhov ntau tshaj plaws ntawm no "nanmadu". Iberodynamic simulation qhia tau tias cov qauv nkhaus sab saum npoo txo cov cua tshuab siab thauj mus rau 27% ntawm lub tiaj tiaj. Cov duab nco tagnrho cov pob hinges yog embedded hauv txhua lub rooj tsavxwm, thiab thaum cua kub tshaj 40m / s, viav vias lub viav vias ntawm lub tsev yog txo los ntawm 83%. Cov neeg nuv ntses pom tias cov phiaj qub tsis tau hloov pauv mus ua los tiv thaiv kev tawm tsam hauv 6- meter Meter High School. Tsoomfwv Txoj Kev Npaj Pab Nyiaj tshwj xeeb uas tau coj raws li homestays uas homestays tau txais cov thev naus laus zis no tuaj yeem tau txais 30% kev pov hwm them nqi puas tau txo. Cov kws tshawb fawb cov ntaub ntawv yog tsim cov qauv xyoob ntoo ntawm cov seaweed, uas tuaj yeem ua rau cov marine ua kom peb lub xyoos tom qab txhuam.

Daim Ntawv Thov Kev Thov Ecological

Cov tsev hav zoov ntsug hauv Dubai Evolved lub PVC qab nthab rau hauv ib lub cua huv av matrix. Txhua ntu square ntawm board yog embedded nrog 300 micro poolocatalytic reactors los ntawm 1.2g ib hnub, thiab kev ua tau zoo sib npaug ntawm 30 tus neeg laus birch ntoo. Lub kaw lus ntse hloov kho lub npoo hydrophilicity raws li kev xav ntawm PM2.5, thiab lub zog purificiency ntawm nag ntuj hnub nce los ntawm 340%. Cov neeg nyob hauv lub xov tooj txawb xov tooj tuaj yeem tshawb xyuas tus nqi "kev pab cuam ntawm huab cua" Nyiaj Siv Ua Haujlwm, thiab cov pob zeb pob khoom tuaj yeem hloov pauv cov nqi vaj tse. Cov kws ua haujlwm ua rau cov kws ua haujlwm tau ua tiav ib qho kev sib tsoo hauv 37- 'meter mets cantilever. Cov zais yog tus tsim ntawm Bionic tus tav, thiab cov khoom dab tsi khoov yog 18 zaug ntawm cov phiaj xwm dog dig. Thaum hmo ntuj hom tau pib, tus txheej ntawm fluorescent hypeae nthuav tawm cov kev ntsuas paug tsis zoo, thiab cov phiaj xwm paug paug paug los ntawm 62% piv nrog cov teeb pom kev zoo ib txwm muaj.
