星系中心的位置被射流本身的光学耀斑所曲解。
This week, in Nature, Eugene Serabyn of the Jet Propulsion Laboratory in California and his colleagues describe a stunning implementation of what is known as an optical vortex coronagraph.本周,加利福尼亚州喷气推进实验室的尤金·瑟拉宾和他的同事将在《自然》杂志中描述被称为光学涡旋日冕的一项惊人的实验。
The optical properties, and hydrodynamics characteristics, as well as the key coupling technologies between the non-diffracting beam and the water jet, have been deeply analyzed and researched.深入研究了水射流导引激光加工系统的光学特性、水光纤的流体力学特性及耦合系统的关键技术。
