These unprecedented energy and luminosity values impose new and stringent requirements on the machine design and performances 这种前所未有的能量和亮度给设计与运行带来了严酷的考验。
" for a poetic oeuvre of great luminosity , sustained by a historical vision , the outcome of a multicultural commitment 他的作品具有巨大的启发性和广阔的历史视野,是其献身多种文化的结果
The second chapter clarifies luminosity and chroma measure keystone , measure methods and instruments word theory 第二章阐述了光度和色度测量的基本原理,测量的方法及其仪器的工作原理。
Main sequence stars have stable luminosities and sizes . to be honest , they are quite boring compare to their deaths 主序星的光度和大小十分稳定,或者你可以说相对于恒星的死亡舞曲,主序阶段相当沈闷。
And on the base of this model , we gain its equation of extinction , consequently can adjust the supernova ' s luminosity distance 并在此模型的基础上推导出了它的消光公式,从而能够校准超新星的光度距离。
We know the luminosity is directly related to the absolute magnitude . so , in practice , we usually use absolute magnitudes instead 由于光度和绝对星等有直接的对应关系,所以很多时赫罗图会选用绝对星等。
While touring their four hundred million revolutions around the machine , a number of effects contribute to dilute the beams and degrade the luminosity 当粒子正在环行4亿圈时,有几种效应会使粒子束变弱,亮度变暗。
Is the most important diagram in discussing stellar evolution . it is a plot of the surface temperature versus the brightness or luminosity of stars 是研究恒星演化最重要的工具,它显示了恒星表面温度和恒星光度的关系。
Recent observations vindicate the assumption : a direct velocity - mass correlation is even tighter than the velocity - luminosity correlation 最近的观测证实了这项假设:速度与质量的直接关系甚至比速度与光度的关系更为紧密。
This system consist of a single - chip microcomputer , a controlling circuit board , a driving circuit board and sensor for luminosity 采用单片机803设计、制作led显示模块扫描控制板;选用cs - 100色度色差仪来作为亮度传感器。
Luminosity is generally understood as a measurement of brightness. Each discipline, however, defines the term differently, depending on what is being measured.
