I. Sooyaalka iyo Hordhaca
Machadka Shanghai ee Physics Applied (SIAP) ee Akadeemiyada Sayniska Shiinaha (CAS) waa machad cilmi-baaris oo muhiim ah oo ku saabsan sayniska nukliyeerka iyo tignoolajiyada, oo leh 'Shaybaadhka Furaha ee Fiisigiska Microinterface iyo Ogaanshaha Akademiyada Sayniska Shiinaha (CAS)', 'Shaybaadhka Muhiimka ah ee Shanghai ee Cryogenic Superconducting iyo Farsamaynta Sare ee Shaybaarka Sare ee Shaybaarka iyo Farsamada dalool ee Soo noqnoqoshada Sare'. Shaybaadhka Furaha ee Shanghai ee Heerkulka Hoose ee Farsamada Daloosha Soo noqnoqoshada Sare'. Qaybaha inverter-ka ee lagu sameeyay iskaashigan ayaa lagu dabaqi doonaa dardar-geliyayaasha tooska ah ee shaybaarrada kor ku xusan, taas oo siin doonta xal muhiim ah cilmi-baarista farsamada ee nukliyeerka.
II. Habka iskaashiga iyo farsamada
Intii wada shaqayntu socotay, labada dhinacba waxa ay ilaalinayeen xidhiidh dhow iyo wada shaqayn. Iyada oo loo marayo shirarka joogtada ah, warbixinnada horumarka iyo isweydaarsiga goobta, labada dhinacba waxay hubiyaan in faahfaahin kasta oo farsamo si sax ah loo fahmo loona aqoonsaday. Habkan isgaadhsiinta hufan ma aha oo kaliya in uu dedejiyo horumarka wax soo saarka, laakiin sidoo kale waxay hagaajinaysaa tayada iyo waxqabadka alaabta.
III. Tignoolajiyada Isku-dhafka ah iyo Guulaha
Soo-dhoweynta mowjadaha gaaban ee waxqabadka sare leh ee loo habeeyey XST ee ASTRI waxay leedahay dabool ballaaran oo isdaba-joog ah (awood u leh helitaanka calaamadaha mowjadaha gaaban ee xadhkaha soo noqnoqda ee badan), awoodda hoos u dhigista awoodda xooggan ( dhib ma leh waa habaynta baaxadda (AM), habaynta soo noqnoqda (FM) ama hal-sideband modulation (SSB), qaataha hirarka gaaban wuxuu u dhimi karaa si hufan oo uu u soo kabsado macluumaadka la qabsan karo ee asalka ah. xaaladaha cimilada iyo waqtiyada). (awood u leh in uu la qabsado xaaladaha cimilada kala duwan iyo waqtiyada calaamadaha faafinta calaamadaha gaaban ee gaaban) iyo sifooyinka kale ee farsamada iyo faa'iidooyinka.
Tan iyo markii XST-ga qaatayaasha mowjadaha gaaban la geliyay shaybaarka, waxay ku guuleysteen sumcadda wanaagsan ee macaamiisha iyagoo leh waxqabadkooda wanaagsan iyo waxqabadka qiimaha sare leh, waxayna kor u qaadeen hal-abuurka iyo horumarinta sayniska iyo tignoolajiyada nukliyeerka, iyagoo gacan ka geysanaya horumarka sayniska iyo tignoolajiyada iyo dhismaha difaaca qaranka ee dalka.
