Masensa matsva evhu anogona kuvandudza fetiraiza yezvirimwa

Fetereza ine nitrogen inoshandiswa kuwedzera kugadzirwa kwechikafu, asi kuburitsa kwayo kunogona kusvibisa nharaunda.Kuti uwedzere kushandiswa kwezviwanikwa, kukwidza goho rekurima, uye kudzikisira njodzi kwezvakatipoteredza, kuenderera uye chaiyo-nguva yekutarisa zvivakwa zvevhu, senge tembiricha yevhu uye kuburitsa fetereza, zvakakosha.Iyo yakawanda-parameter sensor inodiwa kune yakangwara kana chaiyo kurima kuteedzera NOX gasi kuburitsa uye tembiricha yevhu kuti fetireza yakanakisa.

James L. Henderson, Jr. Chirangaridzo Associate Purofesa weUinjiniya Sayenzi uye Mechanics paPenn State Huanyu "Larry" Cheng akatungamirira kukurudzirwa kwe-multi-parameter sensor iyo inobudirira kuparadzanisa zviratidzo zvekushisa uye nitrogen kubvumira kuyerwa kwakarurama kweumwe neumwe.

Cheng akati,“Kuti pave nefotereza inobudirira, panoda kuongororwa nguva dzose uye nguva chaiyo yemamiriro evhu, kunyanya mashandisirwo enitrogen uye tembiricha yevhu.Izvi zvakakosha pakuongorora hutano hwezvirimwa, kuderedza kusvibiswa kwezvakatipoteredza, uye kusimudzira kurima kwakasimba uye nemazvo. ”

Chidzidzo ichi chine donzvo rekushandisa huwandu hwakakodzera goho regoho repamusoro.Kurimwa kwechirimwa kunogona kunge kwakadzikira pane zvakungave kana nitrogen yakawanda ikashandiswa.Kana fetereza ikaiswa zvakanyanyisa, inoraswa, zvirimwa zvinogona kupisa, uye utsi hwe nitrogen hune muchetura hunoburitswa mumhoteredzo.Varimi vanokwanisa kusvika pamazinga akakodzera efetireza yekukura kwembesa nerubatsiro rwekuona nhanho yenitrogen chaiyo.

Co-munyori Li Yang, purofesa muChikoro cheArtificial Intelligence kuChina Hebei University of Technology, akati,“Kukura kwembesa kunokonzerwawo netembiricha, iyo inopesvedzera mashandiro anoita muviri, makemikari, uye utachiona huri muvhu.Kuenderera mberi kwekutarisa kunoita kuti varimi vagadzire nzira nekuita kana tembiricha ichipisa zvakanyanya kana kutonhora zvakanyanya zvirimwa zvavo.

Sekureva kwaCheng, Sensing nzira dzinogona kuwana nitrogen gasi uye zviyero zvetembiricha zvakazvimirira kubva kune mumwe hazviwanzo kutaurwa.Ose magasi uye tembiricha zvinogona kukonzera mutsauko mukuverenga kwe sensor kuramba, zvichiita kuti zviome kusiyanisa pakati pazvo.

Chikwata chaCheng chakagadzira sensor yepamusoro-soro inokwanisa kuona kurasikirwa kwenitrogen pasina tembiricha yevhu.Iyo sensor inogadzirwa nevanadium oxide-doped, laser-induced graphene foam, uye zvakaonekwa kuti doping metal complexes mugraphene inovandudza gasi adsorption uye yekuona kunzwa.

Nekuti membrane yakapfava inodzivirira iyo sensor uye inodzivirira nitrogen gasi kupindira, iyo sensor inongotarisana nekuchinja kwekushisa.Iyo sensor inogona zvakare kushandiswa pasina encapsulation uye pane yakakwirira tembiricha.

Izvi zvinobvumira kuyerwa kwakarurama kwegesi yenitrogen nekusasanganisa zvinokonzerwa nehunyoro uye tembiricha yevhu.Tembiricha uye nitrogen gasi inogona kuve yakazara uye isina kupindira-isina kubatanidzwa uchishandisa yakavharirwa uye isina kuvharwa sensors.

Muongorori akati kudzoreredza tembiricha shanduko uye kuburitsa gasi renitrogen kunogona kushandiswa kugadzira nekushandisa michina yemultimodal ine decoupled sensing nzira dzekurima chaiko mumamiriro ekunze ese.

Cheng akati, "Kugona kuona panguva imwe chete iyo yakaderera-yakaderera nitrogen oxide uye diki tembiricha shanduko inovhura nzira yekugadzirwa kweamangwana multimodal midziyo yemagetsi ine decoupled yekunzwa nzira dzekurima chaiko, kutarisa hutano, uye mamwe maapplication."
