Indlela yokuphepha iingcongconi ngokukhanya?

Iingcongconi zibe zezona ziphambili ekusasazeni iintsholongwane. Sifanele senze njani umsebenzi olungileyo wokukhusela?

Icandelo 1:Umgaqo wothintelo lweengcongconi

1) Xa ii-entomologists zazifunda iimpawu ze-physiological of mosquitoes, zafumanisa ukuba iingcongconi zinovakalelo ngokukodwa kwaye zithanda iintlobo ezithile zokukhanya, ngelixa zichasene ngakumbi kwabanye.

2)Ngokophando lwenzululwazi yanamhlanje, iingcongconi zinamehlo amabini adibeneyo entloko. Iliso ngalinye elintsonkothileyo lineliso elinye elimalunga nama-500 ukuya kuma-600. Okukhona kukho iliso elinye, kokukhona befumana ukukhanya ngakumbi, kwaye ngoko komelela ngakumbi uvakalelo lwabo ekukhanyeni. Ngokwenzululwazi, iingcongconi zichazwa ukuba zineentlobo ezimbini zeempendulo kumaza okukhanya ahlukeneyo, oko kukuthi, ukuphepha ukukhanya kunye nokufuna ukukhanya: Ukukhanya okuluhlaza okwesibhakabhaka ngamaza angaphantsi kwe-500nm kunomtsalane onamandla kwiingcongconi. Nangona kunjalo, ukukhanya okunobude obungaphezulu kwe-500nm, ngakumbi abo banobude obungaphezulu kwe-560nm, bubangela ukuba iingcongconi zibonise ukuziphatha okucacileyo ngexesha lemisebenzi. Iingcongconi ezivezwe ekukhanyeni ngexesha elifanelekileyo ziya kubonisa ukundiza okungahambi kakuhle, ukuncipha kwamandla kwaye zihlale zingashukumi.

3) Ngokusekwe kumgaqo wokuba zonke iingcongconi ziphephe ukukhanya, iinjineli zethu ze-spectral ziye zasebenzisana neqela leengcaphephe zebhayoloji yeengcongconi ezisuka kwiYunivesithi yezoLimo yase-China ukuphuhlisa i-spectrum ekhethekileyo egxotha ngokufanelekileyo iingcongconi ngokusebenzisa ubuchwepheshe obukhethekileyo be-ELightech. Ngokuhlola rhoqo kunye novavanyo phakathi kwemibala emininzi, baye baphuhlisa ngempumelelo i-spectrum ekhethekileyo egxotha ngokufanelekileyo iingcongconi, kunye nesantya esisebenzayo sokuthintela iingcongconi esingaphezulu kwe-91.5%.

Umcu we-LED wobungqina bengcongconi oveliswe yi-Mingxue Optoelectronics, ukhupha ukukhanya kwe-amber, enokuvelisa ukukhanya okukhulu okungathandwa ziingcongconi, ngaloo ndlela kufezekiswa isiphumo sokugxotha iingcongconi. Ukukhanya okubonakalayo okukhutshwa sesi sibane sobungqina bengcongconi kuphumelela ngokwenene ukukhanya kwe-zero blue kunye ne-zero violet, okungabangeli ungcoliseko okanye ingozi kumzimba womntu okanye okusingqongileyo. Yimveliso ehambelana nokusingqongileyo kwaye okwangoku yeyona ikhuselekileyo kwaye ikhuseleke kakhulu kokusingqongileyo, imveliso yobungqina bengcongconi emzimbeni ekhaya nakwamanye amazwe.

1. Umkhuhlane weDengue:

Ngokutsho kwengxelo yeWorld Health Organization, ukwanda kwesifo sedengue fever kuye kwanda kakhulu ehlabathini lonke kumashumi eminyaka akutshanje. Esi sifo sigqugqisa kumazwe angaphezu kwe-100 eAfrika, eMerika, kwiMpuma yeMeditera, kuMzantsi-mpuma weAsia nakwintshona yePasifiki. Amazwe aseMerika, uMzantsi-mpuma weAsia kunye nommandla okwiNtshona yePasifiki ngawona achaphazeleka kakhulu. Uphononongo lwakutsha nje luqikelela ukuba kukho malunga ne-390 yezigidi zeemeko zosulelo lwe-dengue fever kwihlabathi jikelele nyaka ngamnye. I-3.9 yeebhiliyoni zabantu kumazwe angama-128 basengozini yosulelo lwe-dengue virus, kunye nezinga lokufa ukusuka kwi-15% ukuya kwi-50%. E-China, ezona ndawo zisemngciphekweni omkhulu zise-Guangdong, Guangxi nakwezinye iindawo.
