I. Ngano uye Nhanganyaya
Shanghai Institute of Applied Physics (SIAP) yeChinese Academy yeScience (CAS) inzvimbo yakakosha yekutsvagisa mumunda wesainzi yenyukireya uye tekinoroji, ine 'Key Laboratory yeMicrointerface Physics uye Kuonekwa kweChinese Academy yeScience (CAS)', 'Shanghai Key Laboratory yeCryogenic Superconducting uye High-Frequency Key Laboratory' uye High-Frequency Cavity Cavity Cavity yeShanghai Frequency Cavity Technology'. Shanghai Key Laboratory yeLow Temperature Superconducting Yakakwira Frequency Cavity Technology '. Iyo inverter zvikamu zvakagadziridzwa mumubatanidzwa uyu zvichashandiswa kune superconducting linear accelerators epamusoro marabhoritari, iyo ichapa mhinduro yakakosha yekutsvagisa yakashandiswa yehunyanzvi hwenyukireya.
II. Co-operation Mode uye Mechanism
Mukufamba kwekushandira pamwe, mapato ese ari maviri akachengetedza kutaurirana kwepedyo uye kubatana. Kuburikidza nemisangano yenguva dzose, mishumo yekufambira mberi uye kuchinjana kwepa-saiti, mapato ese ari maviri anovimbisa kuti zvese zvehunyanzvi zvinonzwisiswa uye zvinozivikanwa. Iyi inyanzvi yekutaurirana nzira haingo mhanyisa kufambira mberi kwechigadzirwa, asi zvakare inovandudza kunaka uye kuita kwezvigadzirwa.
III. Synthesis Tekinoroji uye Zvakabudirira
Iyo yakakwira-inoshanda shortwave inogamuchira yakagadziridzwa neXST yeASTRI ine yakafara frequency kufukidzwa (inokwanisa kugamuchira mapfupi masaini eakawanda frequency mabhendi), yakasimba demodulation kugona (zvisinei kuti ndeye amplitude modulation (AM), frequency modulation (FM) kana single-sideband modulation (SSB), iyo shortwave inogamuchira inogona kudzoreredza iyo inogoneka yepakutanga uye kudzoreredza ruzivo rwepakutanga kuparadzira maitiro pasi pemamiriro ekunze akasiyana uye nguva dzenguva). (inokwanisa kuchinjika kune akasiyana mamiriro ekunze uye nguva dzenguva pfupi-wave chiratidzo chekuparadzira maitiro) uye humwe hunyanzvi maficha uye zvakanakira.
Sezvo XST's short-wave receivers vakaiswa murabhoritari, vakakunda mukurumbira wakanaka wevatengi nekuita kwavo kwakanaka uye nekuita kwemutengo wakakwira, uye vakasimudzira kuvandudzwa nekuvandudzwa kwesainzi yenyukireya uye tekinoroji, vachiita mipiro yakakosha kubudiriro yesainzi uye tekinoroji uye kuvaka kwedziviriro yenyika.
