The star becomes very big and the surface temperature decreases , although the core temperature is still very high and the total luminosity is also high 虽然核心仍保持炽热,但膨胀令表面温度下降,结果星光变红,最后演化为一颗
Bepc and bes are the only tools of its kind in the world , which operate in the tau - charm energy region with high luminosity 子计数器的分辨率是北京正负电子对撞机的重要性能指标,其z向分辨率是决定探测器的性能好坏的标准。
This subject focus on the issues about how to resolve the luminosity of led module . we devised a set device for measuring luminosity of led module 设计了一套显示模块的控制和驱动电路,采用亮度测试仪对显示模块的亮度进行测试。
Easily accessible , completely the luminosity is good , there are district gardens . the large balcony of lavatory of independent kitchen , build the bridal chamber hard - coverly 交通便利,透光度好,有小区花园。独立厨厕大阳台,精装修新房。
Therefore , the color of a star is mainly determined by its surface temperature , but its luminosity is determined both by its surface temperature and the surface area 所以,恒星的颜色由表面温度所决定,而恒星的光度则由表面温度和表面面积所决定。
In both the restaurant and the lounge of the island pacific hotel , a spectacular glass facade blends the opulence of the interiors and the luminosity of the victoria harbour 不论是咖啡厅或是酒吧,全天候玻璃幕墙令室内绚烂的格调与维港融为一体。
When studying type ia supernovae , astronomers found that not only they have similar light curve , they also have the same peak luminosity 在研究ia型超新星type ia supernovae时,天文学家发现它们不单在光度变化上非常相似,而且在最光亮时的亮度也极为一致。
Gain an understanding of tonal range and how to adjust lighting and exposures using techniques like luminosity masking , light painting and creative ways of combining multiple exposures 本教学教授色调范围的基本知识,并告诉大家如何在图象中调整光线,暴光,与色彩合成
Luminosity is generally understood as a measurement of brightness. Each discipline, however, defines the term differently, depending on what is being measured.
