Kodi kupewa udzudzu ndi kuwala?

Udzudzu wakhala woyamba kufalitsa ma virus. Kodi tiyenera kuchita chiyani kuti tipeze chitetezo chabwino?

Gawo 1: Mfundo yopewera udzudzu

1) Pamene akatswiri a entomologists amaphunzira za thupi la udzudzu, adapeza kuti udzudzu umakhudzidwa kwambiri komanso umakonda mitundu ina ya kuwala, pamene iwo amadana kwambiri ndi ena.

2) Malinga ndi kafukufuku wamakono wa sayansi, udzudzu uli ndi maso awiri pamutu pawo. Diso lililonse lili ndi maso amodzi pafupifupi 500 mpaka 600. Pamene maso amodzi amakhala ochulukirapo, amalandila kuwala kwambiri, ndipo motero amamva mphamvu zawo pakuwala. Mwasayansi, udzudzu umatanthauzidwa kuti uli ndi mitundu iwiri ya mayankho ku mafunde osiyanasiyana a kuwala, ndiko kupewa-kupewa kuwala ndi kufunafuna kuwala: Kuwala kwa buluu ndi mafunde apansi pansi pa 500nm kumakopa kwambiri udzudzu. Komabe, kuwala kokhala ndi mafunde otalika kuposa 500nm, makamaka omwe ali ndi mafunde akulu kuposa 560nm, kumapangitsa udzudzu kuwonetsa machitidwe ozemba panthawi yantchito. Udzudzu womwe umawonekera pa kuwala munthawi yake umawonetsa kuuluka kosasunthika, kuchepa kwa mphamvu komanso kukhala osasunthika.

3）Kutengera mfundo yakuti udzudzu wonse umapewa kuwala, akatswiri athu opanga ma spectral agwirizana ndi gulu la akatswiri a sayansi ya udzudzu ochokera ku South China Agricultural University kuti apange mawonekedwe apadera omwe amathamangitsa udzudzu mogwira mtima pogwiritsa ntchito luso lapadera la ELightech. Kupyolera mukuyang'ana mosalekeza ndikuwunika pakati pa zowonera zambiri, apanga bwino mawonekedwe apadera omwe amathamangitsa udzudzu, ndi chiwopsezo choletsa udzudzu choposa 91.5%.

Mzere wotsimikizira udzudzu wa LED wopangidwa ndi Mingxue Optoelectronics, kuwala kwa amber, komwe kumatha kutulutsa kuwala kochulukirapo komwe udzudzu sakonda, potero kukwaniritsa zotsatira za kuthamangitsa udzudzu. Kuwala kowoneka bwino komwe kumatulutsidwa ndi nyali yoteteza udzudzuyi kumakwaniritsadi zero buluu ndi ziro violet, zomwe sizikuyipitsa kapena kuvulaza thupi la munthu kapena chilengedwe. Ndi mankhwala ochezeka ndi zachilengedwe ndipo pakadali pano ndi otetezeka kwambiri komanso ochezeka kwambiri ndi chilengedwe komanso osateteza udzudzu kunyumba ndi kunja.

Gawo 2: Ngozi ya Udzudzu

1, Dengue fever:

Malinga ndi lipoti la Bungwe Loona za Umoyo pa Dziko Lonse, chiwerengero cha matenda a dengue chakwera kwambiri padziko lonse m’zaka makumi angapo zapitazi. Matendawa amapezeka m'mayiko oposa 100 ku Africa, America, Eastern Mediterranean, Southeast Asia ndi Western Pacific. Madera aku America, Southeast Asia ndi Western Pacific ndiwo adakhudzidwa kwambiri. Kafukufuku waposachedwapa akuti padziko lonse pali anthu pafupifupi 390 miliyoni omwe amadwala matenda a dengue fever chaka chilichonse. Anthu 3.9 biliyoni m'maiko 128 ali pachiwopsezo chotenga kachilombo ka dengue, ndipo anthu amafa kuyambira 15% mpaka 50%. Ku China, madera omwe ali pachiwopsezo chachikulu ali ku Guangdong, Guangxi ndi malo ena.

2, malungo:

Malungo alembedwa ndi World Health Organisation kukhala amodzi mwa matenda atatu oopsa, kuphatikiza AIDS ndi chifuwa chachikulu. Chaka chilichonse, anthu mamiliyoni mazanamazana kapena mamiliyoni ambiri amafa ndi malungo padziko lonse lapansi. Malungo amapha anthu pafupifupi mamiliyoni atatu chaka chilichonse. Udzudzu wa Anopheles, womwe umatha kufalitsa malungo, umagawidwa ku Central ndi South America, Africa, Oceania ndi Central Asia, ndipo Africa ndi yomwe imakhudzidwa kwambiri. Mu Afirika, pafupifupi, mwana amafa ndi malungo masekondi 30 aliwonse. Ku China, malungo amafalitsidwa makamaka ndi udzudzu waku China wotchedwa Aedes.

3, Mliri wa encephalitis B:

Epidemic encephalitis B imafalikiranso ndi udzudzu wa Culex ndi udzudzu wa Aedes, ndipo umatchedwanso encephalitis. Udzudzu ukaluma ndi kuyamwa magazi a anthu kapena nyama zomwe zili ndi kachilomboka, amayamba kupatsirana pakapita nthawi. Zikaluma anthu opanda chitetezo chokwanira, zimatha kuyambitsa matenda, omwe pakati pawo ndi ana omwe amavutika kwambiri.

Poyankha nkhaniyi, tapanga achounikira choteteza udzudzundipo ili ndi zabwino izi:

1-Pulojekitiyi ndi njira yopewera udzudzu. Simapha chamoyo chilichonse ndipo sichisokoneza udzudzu wachilengedwe. Ndi chilengedwe wochezeka mankhwala.
Zimatengera kuwala kofiira ndi kobiriwira monga mawonekedwe akuluakulu owonetserako, omwe ali opindulitsa kwa maso aumunthu, kuswana nyama ndi kukula kwa zomera, ndipo ndi otetezeka komanso odalirika.

2-Sizidzayambitsa kuipitsa kwa mankhwala. Kuwala kulibe kuwala kwa buluu kapena kofiirira ndipo kumagwiritsa ntchito magetsi amtundu wa stroboscopic, omwe angatsimikizire chitetezo chazithunzi za maso a anthu ndi nyama.
Mawonekedwe a mawonekedwe ndi mawonekedwe a nyali omwe amatengedwa ndi mankhwalawa amapangidwa mofanana ndi patent, zomwe zingapangitse kuti mawonekedwe a mankhwalawa akhale okhazikika komanso odalirika, komanso kupititsa patsogolo moyo wautumiki wa nyali ndi zotsatira za udzudzu.

3-Kuyesa kwasayansi kwatsimikizira kuti udzudzu umatsutsana ndi mphamvu zowoneka bwino za 570-590nm. Izi zitha kukwaniritsa izi ndikuthamangitsa tizilombo. Poyerekeza ndi luso alipo wamba LED udzudzu-umboni nyali, ntchito imeneyi kwathunthu kupewa sipekitiramu pansipa 500nm kuti akhoza kukopa udzudzu, ndi dzuwa bwino.

4-Pambuyo poyesa, malo owonetsera udzudzu a nyali imodzi ya mankhwalawa amafika pa 0,8 mpaka 1 mita imodzi pa watt, yomwe ndi yabwino kwa mankhwala akuluakulu a udzudzu. Makamaka m'nyengo yoswana udzudzu, udzudzu ukhoza kuthamangitsa udzudzu kumadera amadzi ndi malo oswana, zomwe zimathandiza kuchepetsa kwambiri kuswana ndi kuchulukana kwa udzudzu.
Nyali zathu zakunja zakhala zikugwiritsidwa ntchito popanga ma radiation osagwirizana ndi madzi komanso anti-ultraviolet. Sangagwiritsidwe ntchito m'nyumba zokha komanso kunja, makamaka m'madera, m'mapaki, m'minda ndi malo ena.

5-Chifukwa cha kutengera ukadaulo wa LED, imapulumutsa magetsi ndi mphamvu poyerekeza ndi nyali zachikhalidwe zoletsa udzudzu.
Chofunika kwambiri ndi chakuti zinthu zonse zikhoza kusinthidwa kwa makasitomala!Lumikizanani nafekuti mumve zambiri!
