单词 Inertial confinement
释义

Inertial confinement

原声例句
彭博洞察

The idea behind inertial confinement is you hold plasma for a very short time in a very small space.

惯性限制背后的想法是，您可以在非常小的空间内将等离子体保持很短的时间。

彭博洞察

Back in Oxford, First Light Fusion is taking what might be the most original approach of any fusion company, borrowing from a branch of fusion called inertial confinement.

回到牛津， First Light Fusion 采用了可能是所有聚变公司中最原始的方法，借鉴了称为惯性约束的聚变分支。

彭博洞察

So, one example of inertial confinement is where lasers, very high-powered lasers, are used to heat a very small amount of hydrogen for nanoseconds, that is billionths of a second.

因此，惯性限制的一个例子是激光，非常高功率的激光，用于在纳秒内加热非常少量的氢，即十亿分之一秒。

惯性局限融合 Inertial confinement fusion

（重定向自Inertial confinement）
以雷射进行惯性局限融合的图解。蓝色箭头代表雷射；橘色代表固态球状核燃料向外爆裂的力量；紫色代表因雷射热能而产生向内的惯性作用力。 1. 雷射光束，或是以雷射产生的X光，快速加热燃料球表面，在周围形成电浆。 2. 燃料核因为表面爆裂产生向内的反作用力，遭到挤压。 3. 当燃料核的密度比铅还大二十倍，温度到达100,000,000 ˚C，进入最后阶段。 4. 压缩后的燃料核，产生的热量快速向外放射，发散的能量是雷射光束加在燃料球上的数倍。
El confinamiento inercial de fusión que emplea láseres ha progresado velozmente en los años 1970 y comienzos de los años 1980 hasta el punto de disponer de unos cuantos pulsos para fusionar un objetivo con diez millones de kilojoules. En la ilustración se puede ver un láser 10 beam LLNL NOVA, mostrado en 1984. Esta instalación viene a suplir el viejo proyecto de su predecesor, el láser Shiva.
Una micro-cápsula empleada como combustible en el confinamiento inercial de fusión (a menudo denominada
Indirect drive laser ICF uses a hohlraum which is irradiated with laser beam cones from either side on its inner surface to bathe a fusion microcapsule inside with smooth high intensity X-rays. The highest energy X-rays can be seen leaking through the hohlraum, represented here in orange/red.

惯性局限融合（英语：Inertial confinement fusion，缩写为ICF），也译为局限惯性核融合、惯性约束核融合、惯性限制氢融合、惯性局限融合，是一种核融合的技术。这项技术利用雷射的冲击波使得通常包含氘和氚的燃料球达到极高的温度和压力，来引发核融合反应。

惯性约束是实现可控核聚变的两大主流方案之一（另一个是磁约束）。美国的国家点火设施（NIF）是目前最大的惯性约束聚变装置，以环空器进行实作，于2013年成功一次核融合反应实验，使燃料球放出比施加雷射还大的能量。法国一个类似的大型设备百万焦耳激光（Laser Mégajoule，LMJ）也在进行相关研究。

Inertial confinement fusion 惯性局限融合

（重定向自Inertial confinement）
Inertial confinement fusion using lasers rapidly progressed in the late 1970s and early 1980s from being able to deliver only a few joules of laser energy (per pulse) to being able to deliver tens of kilojoules to a target. At this point, incredibly large scientific devices were needed for experimentation. Here, a view of the 10 beam LLNL Nova laser, shown shortly after the laser's completion in 1984. Around the time of the construction of its predecessor, the Shiva laser, laser fusion had entered the realm of
Indirect drive laser ICF uses a hohlraum which is irradiated with laser beam cones from either side on its inner surface to bathe a fusion microcapsule inside with smooth high intensity X-rays. The highest energy X-rays can be seen leaking through the hohlraum, represented here in orange/red.
Schematic of the stages of inertial confinement fusion using lasers. The blue arrows represent radiation; orange is blowoff; purple is inwardly transported thermal energy. 1. Laser beams or laser-produced X-rays rapidly heat the surface of the fusion target, forming a surrounding plasma envelope. 2. Fuel is compressed by the rocket-like blowoff of the hot surface material. 3. During the final part of the capsule implosion, the fuel core reaches 20 times the density of lead and ignites at 100,000,000 ˚C. 4. Thermonuclear burn spreads rapidly through the compressed fuel, yielding many times the input energy.
An Inertial confinement fusion target, which was a cylindrical hohlraum target of D-T, being compressed by the Nova Laser. This shot was done in 1995. The image shows the compression of the target, as well as the growth of the Rayleigh-Taylor instabilities.[6]

Inertial confinement fusion (ICF) is a type of fusion energy research that attempts to initiate nuclear fusion reactions by heating and compressing a fuel target, typically in the form of a pellet that most often contains a mixture of deuterium and tritium.
