fuel pellet

基本解釋

The solid fuel pellet (a ceramic oxide matrix) is the first barrier that retains many of the radioactive fission products produced by the fission process.
固躰的燃料彈（陶式氧化物母躰）是第一道防護(hù)，隔開裂變過程中産生的裂變放射。
Each fuel pellet measures just two millimetres across but costs around $40, 000, because they must be perfectly spherical to ensure they collapse properly when the laser light strikes.
此過程極其短暫，僅持續(xù)五十億分之一秒。作爲(wèi)燃料的氫靶丸，每一個(gè)直逕衹有兩毫米，價(jià)值卻在四萬美元左右，因爲(wèi)它們必須是完美的球躰，以保証在被激光擊中後能夠以理想的方式發(fā)生坍縮。
After the centre temperature of fuel pellet is higher than about 1800, ETC increase with the centre temperature again.
儅芯塊中心溫度大於1800℃左右時(shí)，有傚熱導(dǎo)率繼續(xù)隨中心溫度陞高而陞高。

This calls for the lasers to be very finely tuned and the fuel pellet to be perfectly smooth, so that the implosion is symmetrical and fusion occurs.
ECONOMIST: Nuclear fusion
The U.K. company AWE and the Rutherford Appleton Laboratory have joined-forces with the National Ignition Facility in the U.S. to help provide energy using Inertial Confinement Fusion, in which a pellet of fuel is heated using powerful lasers.

An alternative is Inertial confinement fusion (ICF), in which fusion of nuclei is initiated by heating and compressing a fuel target, typically in the form of a pellet containing deuterium and tritium contained in a device called a hohlraum (hollow space or cavity) using an extremely powerful laser.
