Once this kind of data is used to reconstruct the image directly , beam - hardening artifacts appear in the reconstructed image 若直接用多色投影数据来重建图像，就会出现射束硬化伪迹。
A group of nasa - supported researchers are going to test the equivalence principle by shooting laser beams at the moon 一组nasa资助的研究人员正在用激光射束击月球的方法，检验等量原理。

Amendment 1 - medical electrical equipment - part 2 - 11 : particular requirements for the safety of gamma beam therapy equipment 修改件1 .医用电气设备.第2 - 11部分:射束治疗设备安全的特殊要求
Viscosity and viscometric fixed points of glass - method for the determination of annealing point and strain point by beam bending 玻璃粘度和测定粘度固定点.第7部分:采用射束弯曲法对退火点和应力点的测定方法
" determination of the bond behaviour between reinforcing steel and autoclaved aerated concrete by the " beam test " - part 1 : short term test " 用射束试验法测定钢筋和高压蒸汽加气水泥间的粘结情况.第1部分:短时试验
The beam from kek carries higher - energy neutrinos , which can be spotted easily even with the surviving tubes spread more sparsely across the detector Kek产生的射束带有较高能的微中子，所以即使是只用幸存但散布较疏的光电管，也仍可轻易将之侦测出来。
Like ligo , virgo is a so - called michelson interferometer : light from a laser passes a beam splitter and travels down two perpendicular evacuated pipes 和ligo一样， virgo基本上是一具迈克生干涉仪，来自雷射的光束通过射束分离器，然后分别循两条相互垂直的真空管道行进。
If a user in a beam - switching network is near the edge of a beam , the signal that he or she transmits may bounce into the adjacent beam before reaching the beam - switching array 射束交换网络的用户如果位于波束边缘，他所发射的讯号在抵达射束交换阵列之前，可能会先反射到邻近波束中。
Technical system includes the injector and the accelerator subsystem , synchrotron , beam transport , gantry with beam transport and nozzle , treatment couch and control subsystems etc 技术系统包括用作入射器的加速器、高能加速器（可采用同步?旋加速器） 、射束输送管、旋转架质子输送和射?管口、治疗床、管制次系统等。
