粒子物理学的一些理论推测说有可能,尽管这些维度蜷缩在极小的闭路里,只有利用高能粒子碰撞才能探测得到。
Some theories in particle physics speculate that it might, although these dimensions would be curled up in loops so small, they could probably be probed only in high-energy particle collisions.
在最新一期的《科学快讯》杂志上,Reisseter和她的同事报道发现了跟暗物质有关的两个可能事件,这表明暗物质可能与他们的探测器发生了碰撞,但目前还不能下定论。
In a recent issue of the journal Science Express, Reisseter and her colleagues reported finding two possible events that may or may not be dark matter impacts on their detectors.
据称,在两个弱作用大质量粒子碰撞时会发生湮灭,并且放出伽马射线,类似费尔米卫星的探测器能够捕捉到这种信号。
These annihilations are thought to occur when two WIMPs collide, generating gamma-rays which can be picked up by detectors such as those on board Fermi.
大型探测器放置于这些交汇点以在碰撞后的亚原子残骸中寻找新粒子。
Big detectors are located at these points to look for new particles in the sub-atomic wreckage of the collisions.
另一台设备,探测中子与不同化学分子碰撞后产生的不同伽马射线。
The other device can detect the distinctive gamma rays produced by collisions of neutrons with the atoms of different chemical elements.
它将警告控制人员哪些飞机没有按照计划飞行,并且探测到中期有可能发生的碰撞。
It will alert controllers to flights which are not following their flight plan and detect medium-term conflicts.
可用的传感器包括视觉传感器(彩色照相机)、范围传感器(声波和红外探测器)以及碰撞检测的缓冲。
Available sensors include a vision sensor (color monoscopic camera), range sensors (sonars and IR detectors), and bumpers for collision detection.

高能重离子碰撞物理学主要目的是研究极端条件下核物质的性质,探测夸克—胶子等离子体(QGP)。
The major goal of high energy heavy ion collision is to investigate nuclear matter properties under extreme conditions and detect quark-gluon plasma (QGP).
用等价预测碰撞线代替预测碰撞线,只需要探测视线的角速度,使需要探测的参数减少。文中还提出了外扰动常驻条件下,渐近稳定系统的设计方法。
If predicted collision courses are replaced with equivalent collis'on courses, this method only needs to measure the rotation rate of the Line-of-Sight, therefore, the measured parameters are reduced.
