美国留学14个敏感专业列表
如果自己的专业或研究方向和这些相关.
尽量淡化,或者想好说明和做好被check的心理准备了.
1. CONVENTIONAL MUNITIONS:
Technologies associated with warhead and other large caliber projectiles, reactive armor and warhead defeat systems, fusing, and arming systems.
2. NUCLEAR TECHNOLOGY:
This section covers technologies associated with the production and use of nuclear material for both peaceful and military applications. Included are technologies for enrichment of fissile material, for reprocessing irradiated nuclear fuel to recover produced platinum, production of heavy water for moderator material, plutonium and tritium handling, as well as certain associated technologies related to high energy physics. It includes research and poser reactors, breeder and production reactors, fissile or special nuclear materials; uranium enrichment, including gaseous diffusion, centrifuge, aerodynamics, chemical, electromagnetic isotopic separation (EMIS) laser, isotopic separation (LIS); spent fuel reprocessing, plutonium, mixed oxide nuclear research, inertial confinement fusion (ICF), magnetic confinement fusion, plasma, nuclear fuel fabrication including mixed oxide (uranium-plutonium) fuels (MOX), heavy water production, tritium production and sue, electromagnetic pulse (EMP); hardening technology.
3. MISSILE/MISSILE TECHNOLOGY:
Technologies associated with air vehicles and missile systems. The technology needed to develop a satellite launch vehicle is virtually identical to that needed to build a ballistic missile. Technologies include rocket systems, ballistic missiles, space launch vehicles and sounding rockets and unmanned air equipment and reentry vehicles.
4. AIRCRAFT AND MISSILE PROPULSION AND VEHICULAR SYSTEMS:
The propulsion technologies included are associated with near-earth super and hypersonic flight propulsion systems for aircraft and missiles. Many of these technologies are dual use. Technologies include liquid and solid rocket propulsion systems; missile propulsion and systems integration; individual rocket states or staging/separation mechanism; aerospace thermal and high-performance structures; propulsion systems test facilities.
5. NA VIGATION AND GUIDANCE CONTROL:
These capabilities directly determine the delivery accuracy and lethality of both unguided and guided weapons. The long-term costs to design, build and apply these technologies have been a limiting proliferation factor. Technologies include those associated with internal navigation systems, tracking and terminal homing devices; accelerometers, vehicle and flight control systems.
6. CHEMICAL AND BIOTECHNOLOGY ENGINEERING:
Of specific concern is the ability to develop, produce, and disseminate toxic chemicals, biological and toxin agents. The technologies that could be applied to produce chemical and biological
