Mwinamwake mwawona kale kuti ambiri a Chifalansa akale (ndi kupitirira) amagwiritsa ntchito nyali zachikasu m'malo mwa kuwala koyera / kwachikasu. Ndipo mosiyana ndi momwe mungaganizire, si pazifukwa zokongoletsa.
Nkhaniyi imanena kuti, monga nyali zachikasu zomwe zimasiyanitsa magalimoto a asilikali a ku France kuchokera ku Germany, boma la France linkafunanso kusiyanitsa magalimoto awo pamsewu - zomwe siziri zoona. Kuti tipeze chifukwa chenicheni tiyenera kubwerera ku 1930s za zaka zana zapitazi.
Mu November 1936, lamulo linayamba kugwira ntchito ku France lomwe linkafuna kuti magalimoto onse azikhala ndi nyali zomwe zimatulutsa kuwala kwachikasu - "selective yellow".
Chifukwa chiyani magetsi akutsogolo achikasu?
Chifukwa chake chinali chosavuta: malinga ndi kafukufuku wa Académie des Sciences, kuwala kumeneku kunapangitsa kuwala kocheperako kusiyana ndi kuwala koyera / kwachikasu, makamaka nyengo yomwe si yabwino kuyendetsa (mvula kapena chifunga).
Kuyambira chaka chotsatira, magalimoto onse olembetsedwa ku France - komanso omwe adatumizidwa kunja - adayamba kugwiritsa ntchito nyali zachikasu.
Nyali zakutsogolo zachikaso zinali zogwira mtima kwambiri ndipo nthawi zonse zimakonda kuyendetsa munyengo yovuta monga chifunga kapena mvula.
Chinsinsi chake ndi mmene diso la munthu limasinthira kuwala kwa mitundu yosiyanasiyana. Choyera chimabweretsa pamodzi mitundu yonse, ndipo buluu, indigo ndi violet ndi omwe ali ndi utali wamfupi. Chifukwa chake, ndizovuta kwambiri kuzikonza, kuwonjezera pakupangitsa kuwala kochulukirapo, komwe kumabweretsa kukongola.
Kuchotsa matani awa timapeza kuwala kwachikasu, komwe, mofananamo, kumakhala ndi kuwala kochepa, motero kumapangitsa kuti maso athu agwire ntchito.
Lembetsani ku kalata yathu yamakalata
Kumbali inayi, maphunziro angapo mu theka lachiwiri la zaka za zana la 20 - makamaka kafukufuku wopangidwa ku Netherlands mu 1976 - adatsimikiza kuti pochitapo panalibe kusiyana kwakukulu pakuwoneka pakati pa mitundu iwiri ya kuwala. Zinapezeka kuti mphamvu ya kuwala kwachikasu inali yotsika ndipo izi zinapangitsa kuti madalaivala asamawoneke bwino, osati kuti aziwoneka bwino.
Chowonadi ndi chakuti kuyatsa magalimoto panthawiyo sikunali kotchuka, mosasamala kanthu kuti kuwalako kunali koyera kapena kwachikasu. Monga china chilichonse, kuunikira kudasinthika kwazaka zambiri ndipo, mokakamizidwa ndi European Union, yomwe inkafuna kukhazikitsa malamulowo, France idayamba kutengera nyali zoyera mu 1993 m'malo mosankha chikasu, kutsatira chitsanzo cha mayiko ena aku Europe .
Masiku ano, nyali zachikasu ndizoletsedwa ku France, kupatula magalimoto olembetsedwa 1993 isanafike kapena ngati nyali zachifunga. Ndipo mu GT's ku Le Mans ...
