“Ilanga nenyanga kuphephile? “
Ezinkulungwaneni zeminyaka edlule, u-Qu Yuan waveza ifilosofi yakhe yendawo yonke kulo mbuzo. I-Mars ibilokhu ibhekwa njengento ebalulekile kusukela ezikhathini zasendulo. Kusukela ngawo-1960 kuye kwaba nemishini engaphezu kuka-40 eya kuMars. Umkhumbi-mkhathi waseChina wango-2021 ubuyisele emuva izithombe ze-Mars ezithathe ukunaka komhlaba wonke.

Buyini ubuchwepheshe obusemuva kwesithombe se-Mars? Ubuchwepheshe be-TDI(Time Delay Integration) bungomunye wabo. Ukuntuleka kokuchayeka ngenxa yejubane eliphezulu lezinto endaweni yonke enkulu kanye nendawo yokukhanya okuphansi kuyisici esikhawulela ikhwalithi yezithombe zokuhlola isikhala. Ungakwandisa kanjani ukuvezwa ukuze uthole izithombe ezingcono? I-TDI inikeza impendulo. I-TDI detector ingumtshina okhethekile we-linearrray detector enesakhiwo sohlelo lwendiza kanye nokuphumayo komugqa womugqa. Uma uthwebula, isithombe siphuma ngokuqhubekayo ngokunyakaza okuhlobene kwento nomtshina. Lolu hlobo lwendlela yokuthwebula lubizwa nangokuthi i-push-sweep imaging, njengoba nje i-mop ihudula inhlabathi ibheke ohlangothini olulodwa, indawo eyihudulela ngaphesheya yindawo lapho isithombe siqedwa khona (esithombeni ngezansi).

Uma kuqhathaniswa nomtshina womugqa wendabuko, umtshina we-TDI ungadalula ithagethi efanayo izikhathi eziningi, wandise kakhulu ukuqoqwa kwamandla okukhanya, futhi unezinzuzo zokuphendula ngokushesha, ububanzi obuguquguqukayo, njll., futhi ungakhiqiza izithombe zokucaca okuphezulu ngesivinini esiphezulu. ezindaweni ezinzima. Ukuthatha izithombe ezinokulungiswa okuphezulu kwe-Mars ngobuchwepheshe be-TDI isidingo sokuphuma ohlelweni lwenyanga-yomhlaba futhi uhlole indawo yonke. Ingabe kuyadingeka ukusebenzisa ubuchwepheshe be-TDI ekutholeni ukudla?

Kulinganiselwa ukuthi inani labantu emhlabeni lizodlula izigidigidi eziyisi-8 ngo-2025. Ukunikezwa kokudla cishe kuzodinga ukuphinda kabili, ngokushesha futhi okunembe kakhudlwana kwemishini yokuhlola, okuyodingeka emabhizinisini okucubungula ukudla ukuze kuzuze umkhiqizo omkhulu, ukukhiqizwa kokudla okusezingeni eliphezulu, kanye ukusetshenziswa kobuchwepheshe be-TDI i-x-ray imishini yokubona umzimba wangaphandle (ngemuva kwalokhu ebizwa ngokuthi umshini we-x-ray), ongakhawulela ukushuba kwemisebe, uthuthukise isivinini sokuskena nokucaca kwesithombe, uthuthukise ukusebenza kahle kokutholwa, ngokuhambisana nenkambiso yemboni yokudla ukuthuthukiswa ukuhlangabezana nokuthuthukiswa kwezidingo zokuphepha kokudla.
I-Techik inokuqonda ekuthuthukisweni komkhakha wokucubungula ukudla. Umshini okhaliphile we-x-ray, osebenzisa umtshina wobuchwepheshe we-TDI onesivinini esikhulu futhi onencazelo ephezulu, wethula izici zesithombe sencazelo ephezulu, ukusetshenziswa kwamandla okuphansi kanye nemisebe ephansi, futhi usiza amabhizinisi okucubungula ukudla ukuthi angene emgudwini osheshayo wentuthuko.
01 Ukuchazwa kwesithombe kwencazelo ephezulu
Umshini ohlakaniphile we-X-ray we-Techik osebenzisa umphumela wokuchayeka we-TDI technology detector uyiphinda izikhathi ezingu-8 umtshina womugqa wendabuko ophumayo we-x-ray imaging enencazelo ephezulu, ekhanyayo futhi emnyama, kanye nomuzwa ongcono wokulandelana, ongabonisa kangcono imininingwane izinto ezilinganiswayo ezithuthukisa ngempumelelo ukunemba kokutholwa.
02 Ukusetshenziswa kwamandla okuphansi 02
Umtshina wobuchwepheshe we-TDI wenza umshini we-x-ray ukwazi ukuthola isithombe esicacile ngomthamo omncane we-x Ray, bese wehlisa ngempumelelo amandla adingekayo ekusebenzeni kwawo.
03 isivinini sokubona ngokushesha03
Ukusebenzisa umtshina we-TDI kungakhawulela ukushuba kwemisebe, kuthuthukise isivinini sokubona, futhi kwenze umshini we-x-ray ohlakaniphile uzivumelanise nolayini wokukhiqiza isivinini esiphezulu.
04 Ukuphepha okwengeziwe kanye nokuvikelwa kwemvelo
Ukusetshenziswa kwamandla okuphansi kanye nokucushwa kwemishini yemisebe ephansi akuthuthukisi nje kuphela ukuphepha nokuthembeka komshini ohlakaniphile we-x-ray we-Techik, kodwa futhi kusiza ukonga amandla nokuvikela imvelo.
05 Impilo ende yesevisi
Umtshina we-TDI wehlisa amandla okukhiphayo, ukushisa komthombo we-x-ray, umthamo wezinto ezisetshenziswayo, futhi wenza umshini we-x-ray uzinze futhi usebenze isikhathi eside.
06 Izindleko eziphansi
Impilo ende yesevisi, ukusetshenziswa kwamandla okuncane, ukuchithwa kokushisa okuncane, umthamo omncane nezinye izici zenza izindleko eziphansi zokusebenzisa umshini we-x-ray.
Ngokusekelwe ocwaningweni lohlelo lokusebenza lobuchwepheshe kanye Nokuhlangenwe nakho kweminyaka engaphezu kwe-10 ye-R & D, i-Techik izibophezele kubuchwepheshe bokutholwa kwe-spectrum eku-inthanethi kanye nokuphindaphinda komkhiqizo, ihlinzeka ngemishini yokuhlonza ehlakaniphile, izixazululo eziguquguqukayo neziqondene nomuntu ezimbonini zokudla nezemithi.
